GE2020: The Roar of the Swing Voter

Hi everyone, this is my first ever post here.
I run a little website called The Thought Experiment where I talk about various issues, some of them Singapore related. And one of my main interests is Singaporean politics. With the GE2020 election results, I thought I should pen down my take on what us as the electorate were trying to say.
If you like what I wrote, I also wrote another article on the state of play for GE2020 during the campaigning period, as well as 2 other articles related to GE2015 back when it was taking place.
If you don't like what I wrote, that's ok! I think the beauty of freedom of expression is that everyone is entitled to their opinion. I'm always happy to get feedback, because I do think that more public discourse about our local politics helps us to be more politically aware as a whole.
Just thought I'll share my article here to see what you guys make of it :D
Article Starts Here:
During the campaigning period, both sides sought to portray an extreme scenario of what would happen if voters did not vote for them. The Peoples’ Action Party (PAP) warned that Singaporeans that their political opponents “might eventually replace the government after July 10”. Meanwhile, the Worker’s Party (WP) stated that “there was a real risk of a wipeout of elected opposition MPs at the July 10 polls”.
Today is July 11th. As we all know, neither of these scenarios came to pass. The PAP comfortably retained its super-majority in Parliament, winning 83 out of 93 elected MP seats. But just as in GE2011, another Group Representation Constituency (GRC) has fallen to the WP. In addition, the PAP saw its vote share drop drastically, down almost 9% to 61.2% from 69.9% in GE2015.
Singapore’s electorate is unique in that a significant proportion is comprised of swing voters: Voters who don’t hold any blind allegiance to any political party, but vote based on a variety of factors both micro and macro. The above extreme scenarios were clearly targeted at these swing voters. Well, the swing voters have made their choice, their roar sending 4 more elected opposition MPs into Parliament. This article aims to unpack that roar and what it means for the state of Singaporean politics going forward.
1. The PAP is still the preferred party to form Singapore’s Government
Yes, this may come across as blindingly obvious, but it still needs to be said. The swing voter is by its very definition, liable to changes of opinion. And a large factor that determines how a swing voter votes is their perception of how their fellow swing voters are voting. If swing voters perceive that most swing voters are leaning towards voting for the opposition, they might feel compelled to vote for the incumbent. And if the reverse is true, swing voters might feel the need to shore up opposition support.
Why is this so? This is because the swing voter is trying to push the vote result into a sweet spot – one that lies between the two extreme scenarios espoused by either side. They don’t want the PAP to sweep all 93 seats in a ‘white tsunami’. Neither do they want the opposition to claim so much territory that the PAP is too weak to form the Government on its own. But because each swing voter only has a binary choice: either they vote for one side or the other (I’m ignoring the third option where they simply spoil their vote), they can’t very well say “I want to vote 0.6 for the PAP and 0.4 for the Opposition with my vote”. And so we can expect the swing voter bloc to continue being a source of uncertainty for both sides in future elections, as long as swing voters are still convinced that the PAP should be the Government.
2. Voters no longer believe that the PAP needs a ‘strong mandate’ to govern. They also don’t buy into the NCMP scheme.
Throughout the campaign period, the PAP repeatedly exhorted voters to vote for them alone. Granted, they couldn’t very well give any ground to the opposition without a fight. And therefore there was an attempt to equate voting for the PAP as voting for Singapore’s best interests. However, the main message that voters got was this: PAP will only be able to steer Singapore out of the Covid-19 pandemic if it has a strong mandate from the people.
What is a strong mandate, you may ask? While no PAP candidate publicly confirmed it, their incessant harping on the Non-Constituency Member of Parliament (NCMP) scheme as the PAP’s win-win solution for having the PAP in power and a largely de-fanged opposition presence in parliament shows that the PAP truly wanted a parliament where it held every single seat.
Clearly, the electorate has different ideas, handing Sengkang GRC to the WP and slashing the PAP’s margins in previous strongholds such as West Coast, Choa Chu Kang and Tanjong Pagar by double digit percentages. There is no doubt from the results that swing voters are convinced that a PAP supermajority is not good for Singapore. They are no longer convinced that to vote for the opposition is a vote against Singapore. They have realized, as members of a maturing democracy surely must, that one can vote for the opposition, yet still be pro-Singapore.
3. Social Media and the Internet are rewriting the electorate’s perception.
In the past, there was no way to have an easily accessible record of historical events. With the only information source available being biased mainstream media, Singaporeans could only rely on that to fill in the gaps in their memories. Therefore, Operation Coldstore became a myth of the past, and Chee Soon Juan became a crackpot in the eyes of the people, someone who should never be allowed into Parliament.
Fast forward to today. Chee won 45.2% of the votes in Bukit Batok’s Single Member Constituency (SMC). His party-mate, Dr. Paul Tambyah did even better, winning 46.26% of the votes in Bukit Panjang SMC. For someone previously seen as unfit for public office, this is an extremely good result.
Chee has been running for elections in Singapore for a long time, and only now is there a significant change in the way he is perceived (and supported) by the electorate. Why? Because of social media and the internet, two things which the PAP does not have absolute control over. With the ability to conduct interviews with social media personalities as well as upload party videos on Youtube, he has been able to display a side of himself to people that the PAP did not want them to see: someone who is merely human just like them, but who is standing up for what he believes in.
4. Reserved Election Shenanigans and Tan Cheng Block: The electorate has not forgotten.
Tan Cheng Bock almost became our President in 2011. There are many who say that if Tan Kin Lian and Tan Jee Say had not run, Tony Tan would not have been elected. In March 2016, Tan Cheng Bock publicly declared his interest to run for the next Presidential Election that would be held in 2017. The close result of 2011 and Tan Cheng Bock’s imminent candidacy made the upcoming Presidential Election one that was eagerly anticipated.
That is, until the PAP shut down his bid for the presidency just a few months later in September 2016, using its supermajority in Parliament to pass a “reserved election” in which only members of a particular race could take part. Under the new rules that they had drawn up for themselves, it was decreed that only Malays could take part. And not just any Malay. The candidate had to either be a senior executive managing a firm that had S$500 million in shareholders’ equity, or be the Speaker of Parliament or a similarly high post in the public sector (the exact criteria are a bit more in-depth than this, but this is the gist of it. You can find the full criteria here). And who was the Speaker of Parliament at the time? Mdm Halimah, who was conveniently of the right race (Although there was some hooha about her actually being Indian). With the extremely strict private sector criteria and the PAP being able to effectively control who the public sector candidate was, it came as no surprise that Mdm Halimah was declared the only eligible candidate on Nomination Day. A day later, she was Singapore’s President. And all without a single vote cast by any Singaporean.
Of course, the PAP denied that this was a move specifically aimed at blocking Tan Cheng Bock’s bid for the presidency. Chan Chun Sing, Singapore’s current Minister of Trade and Industry, stated in 2017 that the Government was prepared to pay the political price over making these changes to the Constitution.
We can clearly see from the GE2020 results that a price was indeed paid. A loss of almost 9% of vote share is very significant, although a combination of the first-past-the-post rule and the GRC system ensured that the PAP still won 89.2% of the seats in Parliament despite only garnering 61.2% of the votes. On the whole, it’s naught but a scratch to the PAP’s overwhelming dominance in Parliament. The PAP still retains its supermajority and can make changes to the Constitution anytime that it likes. But the swing voters have sent a clear signal that they have not been persuaded by the PAP’s rationale.
5. Swing Voters do not want Racial Politics.
In 2019, Heng Swee Keat, Singapore’s Deputy Prime Minister and the man who is next in line to be Prime Minister (PM) commented that Singapore was not ready to have a non-Chinese PM. He further added that race is an issue that always arises at election-time in Singapore.
Let us now consider the GE2015 results. Tharman Shanmugaratnam, Singapore’s Senior Minister and someone whom many have expressed keenness to be Singapore’s next PM, obtained 79.28% of the vote share in Jurong GRC. This was above even the current Prime Minister Lee Hsien Loong, who scored 78.63% in Ang Mo Kio GRC. Tharman’s score was the highest in the entire election.
And now let us consider the GE2020 results. Tharman scored 74.62% in Jurong, again the highest scorer of the entire election, while Hsien Loong scored 71.91%. So Tharman beat the current PM again, and by an even bigger margin than the last time. Furthermore, Swee Keat, who made the infamous comments above, scored just 53.41% in East Coast.
Yes, I know I’m ignoring a lot of other factors that influenced these results. But don’t these results show conclusively that Heng’s comments were wrong? We have an Indian leading both the current and future PM in both elections, but yet PAP still feels the need to say that Singapore “hasn’t arrived” at a stage where we can vote without race in mind. In fact, this was the same rationale that supposedly led to the reserved presidency as mentioned in my earlier point.
The swing voters have spoken, and it is exceedingly clear to me that the electorate does not care what our highest office-holders are in terms of race, whether it be the PM or the President. Our Singapore pledge firmly states “regardless of race”, and I think the results have shown that we as a people have taken it to heart. But has the PAP?
6. Voters will not be so easily manipulated.
On one hand, Singaporeans were exhorted to stay home during the Covid-19 pandemic. Contact tracing became mandatory, and groups of more than 5 are prohibited.
But on the other hand, we are also told that it’s absolutely necessary to hold an election during this same period, for Singaporeans to wait in long lines and in close proximity to each other as we congregate to cast our vote, all because the PAP needs a strong mandate.
On one hand, Heng Swee Keat lambasted the Worker’s Party, claiming that it was “playing games with voters” over their refusal to confirm if they would accept NCMP seats.
But on the other hand, Heng Swee Keat was moved to the East Coast GRC at the eleventh hour in a surprise move to secure the constituency. (As mentioned above, he was aptly rewarded for this with a razor-thin margin of just 53.41% of the votes.)
On one hand, Masagos Zulkifli, PAP Vice-Chairman stated that “candidates should not be defined by a single moment in time or in their career, but judged instead by their growth throughout their life”. He said this in defense of Ivan Lim, who appears to be the very first candidate in Singaporean politics to have been pushed into retracting his candidacy by the power of non-mainstream media.
But on the other hand, the PAP called on the WP to make clear its stand on Raeesah Khan, a WP candidate who ran (and won) in Sengkang GRC for this election, stating that the Police investigation into Raeesah’s comments made on social media was “a serious matter which goes to the fundamental principles on which our country has been built”.
On one hand, Chan Chun Sing stated in 2015, referring to SingFirst’s policies about giving allowances to the young and the elderly, “Some of them promised you $300 per month. I say, please don’t insult my residents. You think…. they are here to be bribed?”
On the other hand, the PAP Government has just given out several handouts under its many budgets to help Singaporeans cope with the Covid-19 situation. [To be clear, I totally approve of these handouts. What I don’t approve is that the PAP felt the need to lambast similar policies as bribery in the past. Comparing a policy with a crime is a political low blow in my book.]
I could go on, but I think I’ve made my point. And so did the electorate in this election, putting their vote where it counted to show their disdain for the heavy-handedness and double standards that the PAP has displayed for this election.
Conclusion
I don’t say the above to put down the PAP. The PAP would have you believe that to not support them is equivalent to not wanting what’s best for Singapore. This is a false dichotomy that must be stamped out, and I am glad to see our swing voters taking a real stand with this election.
No, I say the above as a harsh but ultimately supportive letter to the PAP. As everyone can see from the results, we all still firmly believe that the PAP should be the Government. We still have faith that PAP has the leadership to take us forward and out of the Covid-19 crisis.
But we also want to send the PAP a strong signal with this vote, to bring them down from their ivory towers and down to the ground. Enough with the double standards. Enough with the heavy-handedness. Singaporeans have clearly stated their desire for a more mature democracy, and that means more alternative voices in Parliament. The PAP needs to stop acting as the father who knows it all, and to start acting as the bigger brother who can work hand in hand with his alternative younger brother towards what’s best for the entire family: Singapore.
There is a real chance that the PAP will not listen, though. As Lee Hsien Loong admitted in a rally in 2006, “if there are 10, 20… opposition members in Parliament… I have to spent my time thinking what is the right way to fix them”.
Now, the PAP has POFMA at its disposal. It still has the supermajority in Parliament, making them able to change any law in Singapore, even the Constitution at will. We have already seen them put these tools to use for its own benefit. Let us see if the PAP will continue as it has always done, or will it take this opportunity to change itself for the better. Whatever the case, we will be watching, and we will be waiting to make our roar heard once again five years down the road.
Majulah Singapura!

Wall Street Week Ahead for the trading week beginning June 29th, 2020

Good Saturday afternoon to all of you here on StockMarket. I hope everyone on this sub made out pretty nicely in the market this past week, and is ready for the new trading week ahead.
Here is everything you need to know to get you ready for the trading week beginning June 29th, 2020.

Fragile economic recovery faces first big test with June jobs report in the week ahead - (Source)

The second half of 2020 is nearly here, and now it’s up to the economy to prove that the stock market was right about a sharp comeback in growth.
The first big test will be the June jobs report, out on Thursday instead of its usual Friday release due to the July 4 holiday. According to Refinitiv, economists expect 3 million jobs were created, after May’s surprise gain of 2.5 million payrolls beat forecasts by a whopping 10 million jobs.
“If it’s stronger, it will suggest that the improvement is quicker, and that’s kind of what we saw in May with better retail sales, confidence was coming back a little and auto sales were better,” said Kevin Cummins, chief U.S. economist at NatWest Markets.
The second quarter winds down in the week ahead as investors are hopeful about the recovery but warily eyeing rising cases of Covid-19 in a number of states.
Stocks were lower for the week, as markets reacted to rising cases in Texas, Florida and other states. Investors worry about the threat to the economic rebound as those states move to curb some activities. The S&P 500 is up more than 16% so far for the second quarter, and it is down nearly 7% for the year. Friday’s losses wiped out the last of the index’s June gains.
“I think the stock market is looking beyond the valley. It is expecting a V-shaped economic recovery and a solid 2021 earnings picture,” said Sam Stovall, chief investment strategist at CFRA. He expects large-cap company earnings to be up 30% next year, and small-cap profits to bounce back by 140%.
“I think the second half needs to be a ‘show me’ period, proving that our optimism was justified, and we’ll need to see continued improvement in the economic data, and I think we need to see upward revisions to earnings estimates,” Stovall said.
Liz Ann Sonders, chief investment strategist at Charles Schwab, said she expects the recovery will not be as smooth as some expect, particularly considering the resurgence of virus outbreaks in sunbelt states and California.
“Now as I watch what’s happening I think it’s more likely to be rolling Ws,” rather than a V, she said. “It’s not just predicated on a second wave. I’m not sure we ever exited the first wave.”
Even without actual state shutdowns, the virus could slow economic activity. “That doesn’t mean businesses won’t shut themselves down, or consumers won’t back down more,” she said.

Election ahead

In the second half of the year, the market should turn its attention to the election, but Sonders does not expect much reaction to it until after Labor Day. RealClearPolitics average of polls shows Democrat Joe Biden leading President Donald Trump by 10 percentage points, and the odds of a Democratic sweep have been rising.
Biden has said he would raise corporate taxes, and some strategists say a sweep would be bad for business, due to increased regulation and higher taxes. Trump is expected to continue using tariffs, which unsettles the market, though both candidates are expected to take a tough stance on China.
“If it looks like the Senate stays Republican than there’s less to worry about in terms of policy changes,” Sonders said. “I don’t think it’s ever as binary as some people think.”
Stovall said a quick study shows that in the four presidential election years back to 1960, where the first quarter was negative, and the second quarter positive, stocks made gains in the second half.
Those were 1960 when John Kennedy took office, 1968, when Richard Nixon won; 1980 when Ronald Reagan’s was elected to his first term; and 1992, the first win by Bill Clinton. Coincidentally, in all of those years, the opposing party gained control of the White House.

Stimulus

The stocks market’s strong second-quarter showing came after the Fed and Congress moved quickly to inject the economy with trillions in stimulus. That unlocked credit markets and triggered a stampede by companies to restructure or issue debt. About $2 trillion in fiscal spending was aimed at consumers and businesses, who were in sudden need of cash after the abrupt shutdown of the economy.
Fed Chairman Jerome Powell and Treasury Secretary Steven Mnuchin both testify before the House Financial Services Committee Tuesday on the response to the virus. That will be important as markets look ahead to another fiscal package from Congress this summer, which is expected to provide aid to states and local governments; extend some enhanced benefits for unemployment, and provide more support for businesses.
“So much of it is still so fluid. There are a bunch of fiscal items that are rolling off. There’s talk about another fiscal stimulus payment like they did last time with a $1,200 check,” said Cummins.
Strategists expect Congress to bicker about the size and content of the stimulus package but ultimately come to an agreement before enhanced unemployment benefits run out at the end of July. Cummins said state budgets begin a new year July 1, and states with a critical need for funds may have to start letting workers go, as they cut expenses.
The Trump administration has indicated the jobs report Thursday could help shape the fiscal package, depending on what it shows. The federal supplement to state unemployment benefits has been $600 a week, but there is opposition to extending that, and strategists expect it to be at least cut in half.
The unemployment rate is expected to fall to 12.2% from 13.3% in May. Cummins said he had expected 7.2 million jobs, well above the consensus, and an unemployment rate of 11.8%.
As of last week, nearly 20 million people were collecting state unemployment benefits, and millions more were collecting under a federal pandemic aid program.
“The magnitude here and whether it’s 3 million or 7 million is kind of hard to handicap to begin with,” Cummins said. Economists have preferred to look at unemployment claims as a better real time read of employment, but they now say those numbers could be impacted by slow reporting or double filing.
“There’s no clarity on how you define the unemployed in the Covid 19 environment,” said Chris Rupkey, chief financial economist at MUFG Union Bank. “If there’s 30 million people receiving insurance, unemployment should be above 20%.

When Will The Economy Recover?

The economy is moving in the right direction, as many economic data points are coming in substantially better than what the economists expected. From May job gains coming in more than 10 million higher than expected and retail sales soaring a record 18%, how quickly the economy is bouncing back has surprised nearly everyone.
“As good as the recent economic data has been, we want to make it clear, it could still take years for the economy to fully come back,” explained LPL Financial Senior Market Strategist Ryan Detrick. “Think of it like building a house. You get all the big stuff done early, then some of the small things take so much longer to finish; I’m looking at you crown molding.”
Here’s the hard truth; it might take years for all of the jobs that were lost to fully recover. In fact, during the 10 recessions since 1950, it took an average of 30 months for lost jobs to finally come back. As the LPL Chart of the Day shows, recoveries have taken much longer lately. In fact, it took four years for the jobs lost during the tech bubble recession of the early 2000s to come back and more than six years for all the jobs lost to come back after the Great Recession. Given many more jobs were lost during this recession, it could takes many years before all of them indeed come back.

The economy is going the right direction, and if there is no major second wave outbreak it could surprise to the upside. Importantly, this economic recovery will still be a long and bumpy road.

Nasdaq - Russell Spread Pulling the Rubber Band Tight

The Nasdaq has been outperforming every other US-based equity index over the last year, and nowhere has the disparity been wider than with small caps. The chart below compares the performance of the Nasdaq and Russell 2000 over the last 12 months. While the performance disparity is wide now, through last summer, the two indices were tracking each other nearly step for step. Then last fall, the Nasdaq started to steadily pull ahead before really separating itself in the bounce off the March lows. Just to illustrate how wide the gap between the two indices has become, over the last six months, the Nasdaq is up 11.9% compared to a decline of 15.8% for the Russell 2000. That's wide!
(CLICK HERE FOR THE CHART!)
In order to put the recent performance disparity between the two indices into perspective, the chart below shows the rolling six-month performance spread between the two indices going back to 1980. With a current spread of 27.7 percentage points, the gap between the two indices hasn't been this wide since the days of the dot-com boom. Back in February 2000, the spread between the two indices widened out to more than 50 percentage points. Not only was that period extreme, but ten months before that extreme reading, the spread also widened out to more than 51 percentage points. The current spread is wide, but with two separate periods in 1999 and 2000 where the performance gap between the two indices was nearly double the current level, that was a period where the Nasdaq REALLY outperformed small caps.
(CLICK HERE FOR THE CHART!)
To illustrate the magnitude of the Nasdaq's outperformance over the Russell 2000 from late 1998 through early 2000, the chart below shows the performance of the two indices beginning in October 1998. From that point right on through March of 2000 when the Nasdaq peaked, the Nasdaq rallied more than 200% compared to the Russell 2000 which was up a relatively meager 64%. In any other environment, a 64% gain in less than a year and a half would be excellent, but when it was under the shadow of the surging Nasdaq, it seemed like a pittance.

Share Price Performance

The US equity market made its most recent peak on June 8th. From the March 23rd low through June 8th, the average stock in the large-cap Russell 1,000 was up more than 65%! Since June 8th, the average stock in the index is down more than 11%. Below we have broken the index into deciles (10 groups of 100 stocks each) based on simple share price as of June 8th. Decile 1 (marked "Highest" in the chart) contains the 10% of stocks with the highest share prices. Decile 10 (marked "Lowest" in the chart) contains the 10% of stocks with the lowest share prices. As shown, the highest priced decile of stocks are down an average of just 4.8% since June 8th, while the lowest priced decile of stocks are down an average of 21.5%. It's pretty remarkable how performance gets weaker and weaker the lower the share price gets.

Nasdaq 2% Pullbacks From Record Highs

It's hard to believe that sentiment can change so fast in the market that one day investors and traders are bidding up stocks to record highs, but then the next day sell them so much that it takes the market down over 2%. That's exactly what happened not only in the last two days but also two weeks ago. While the 5% pullback from a record high back on June 10th took the Nasdaq back below its February high, this time around, the Nasdaq has been able to hold above those February highs.
(CLICK HERE FOR THE CHART!)
In the entire history of the Nasdaq, there have only been 12 periods prior to this week where the Nasdaq closed at an all-time high on one day but dropped more than 2% the next day. Those occurrences are highlighted in the table below along with the index's performance over the following week, month, three months, six months, and one year. We have also highlighted each occurrence that followed a prior one by less than three months in gray. What immediately stands out in the table is how much gray shading there is. In other words, these types of events tend to happen in bunches, and if you count the original occurrence in each of the bunches, the only two occurrences that didn't come within three months of another occurrence (either before or after) were July 1986 and May 2017.
In terms of market performance following prior occurrences, the Nasdaq's average and median returns were generally below average, but there is a pretty big caveat. While the average one-year performance was a gain of 1.0% and a decline of 23.6% on a median basis, the six occurrences that came between December 1999 and March 2000 all essentially cover the same period (which was very bad) and skew the results. Likewise, the three occurrences in the two-month stretch from late November 1998 through January 1999 where the Nasdaq saw strong gains also involves a degree of double-counting. As a result of these performances at either end of the extreme, it's hard to draw any trends from the prior occurrences except to say that they are typically followed by big moves in either direction. The only time the Nasdaq wasn't either 20% higher or lower one year later was in 1986.

Christmas in July: NASDAQ’s Mid-Year Rally

In the mid-1980s the market began to evolve into a tech-driven market and the market’s focus in early summer shifted to the outlook for second quarter earnings of technology companies. Over the last three trading days of June and the first nine trading days in July, NASDAQ typically enjoys a rally. This 12-day run has been up 27 of the past 35 years with an average historical gain of 2.5%. This year the rally may have begun a day early, today and could last until on or around July 14.
After the bursting of the tech bubble in 2000, NASDAQ’s mid-year rally had a spotty track record from 2002 until 2009 with three appearances and five no-shows in those years. However, it has been quite solid over the last ten years, up nine times with a single mild 0.1% loss in 2015. Last year, NASDAQ advanced a solid 4.6% during the 12-day span.

Tech Historically Leads Market Higher Until Q3 of Election Years

As of yesterday’s close DJIA was down 8.8% year-to-date. S&P 500 was down 3.5% and NASDAQ was up 12.1%. Compared to the typical election year, DJIA and S&P 500 are below historical average performance while NASDAQ is above average. However this year has not been a typical election year. Due to the covid-19, the market suffered the damage of the shortest bear market on record and a new bull market all before the first half of the year has come to an end.
In the surrounding Seasonal Patten Charts of DJIA, S&P 500 and NASDAQ, we compare 2020 (as of yesterday’s close) to All Years and Election Years. This year’s performance has been plotted on the right vertical axis in each chart. This year certainly has been unlike any other however some notable observations can be made. For DJIA and S&P 500, January, February and approximately half of March have historically been weak, on average, in election years. This year the bear market ended on March 23. Following those past weak starts, DJIA and S&P 500 historically enjoyed strength lasting into September before experiencing any significant pullback followed by a nice yearend rally. NASDAQ’s election year pattern differs somewhat with six fewer years of data, but it does hint to a possible late Q3 peak.

Selling your Covered Call - Thoughts on How to Select Your Strike and Expiration

Congratulations! You are a bag holder of company XYZ which was thought to be the best penny stock ever. Instead of feeling sorry, you consider selling covered calls to help reduce your cost basis - and eventually get out of your bags with minimal loss or even a profit!
First - let's review the call option contract. The holder of the call option contract has the right but not the obligation to purchase 100 shares of XYZ at the strike price per share. This contract has an expiration date. We assume American style option contracts which means that the option can be exercised at any point prior to expiration. Thus, there are three parameters to the option contract - the strike price, the expiration date and the premium - which represents the price per share of the contract.
The holder of the call option contract is the person that buys the option. The writer of the contract is the seller. The buyer (or holder) pays the premium. The seller (or writer) collects the premium.
As an XYZ bag holder, the covered call may help. By writing a call contract against your XYZ shares, you can collect premium to reduce your investment cost in XYZ - reducing your average cost per share. For every 100 shares of XYZ, you can write 1 call contract. Notice that that by selling the contract, you do not control if the call is exercised - only the holder of the contract can exercise it.
There are several online descriptions about the covered call strategy. Here is an example that might be useful to review Covered Call Description
The general guidance is to select the call strike at the price in which you would be happy selling your shares. However, the context of most online resources on the covered call strategy assume that you either just purchased the shares at market value or your average cost is below the market price. In the case as a bag holder, your average cost is most likely over - if not significantly over - the current market price. This situation simply means that you have a little work to reduce your average before you are ready to have your bags called away. For example, you would not want to have your strike set at $2.50 when your average is above that value as this would guarantee a net loss. (However, if you are simply trying to rid your bags and your average is slightly above the strike, then you might consider it as the strike price).
One more abstract concept before getting to what you want to know. The following link shows the Profit/Loss Diagram for Covered Call Conceptually, the blue line shows the profit/loss value of your long stock position. The line crosses the x-axis at your average cost, i.e the break-even point for the long stock position. The green/red hockey stick is the profit (green) or loss (red) of the covered call position (100 long stock + 1 short call option). The profit has a maximum value at the strike price. This plateau is due to the fact that you only receive the agreed upon strike price per share when the call option is exercised. Below the strike, the profit decreases along the unit slope line until the value becomes negative. It is a misnomer to say that the covered call is at 'loss' since it is really the long stock that has decreased in value - but it is not loss (yet). Note that the break-even point marked in the plot is simply the reduced averaged cost from the collected premium selling the covered call.
As a bag holder, it will be a two-stage process: (1) reduce the average cost (2) get rid of bags.
Okay let's talk selecting strike and expiration. You must jointly select these two parameters. Far OTM strikes will collect less premium where the premium will increase as you move the strike closer to the share price. Shorter DTE will also collect less premium where the premium will increase as you increase the DTE.
It is easier to describe stage 2 "get rid of bags" first. Let us pretend that our hypothetical bag of 100 XYZ shares cost us $5.15/share. The current XYZ market price is $3/share - our hole is $2.15/share that we need to dig out. Finally, assume the following option chain (all hypothetical):
DTE Strike Premium Intrinsic Value Time Value
20 $2.5 $0.60 $0.50 $0.10
20 $5.0 $0.25 $0 $0.25
20 $7.5 $0.05 $0 $0.05
50 $2.5 $0.80 $0.50 $0.30
50 $5.0 $0.40 $0 $0.40
50 $7.5 $0.20 $0 $0.20
110 $2.5 $0.95 $0.50 $0.45
110 $5.0 $0.50 $0 $0.50
110 $7.5 $0.25 $0 $0.25
Purely made up the numbers, but the table illustrates the notional behavior of an option chain. The option value (premium) is the intrinsic value plus the time value. Only the $2.5 strike has intrinsic value since the share price is $3 (which is greater than $2.5). Notice that intrinsic value cannot be negative. The rest of the premium is the time value of the option which is essentially the monetary bet associated with the probability that the share price will exceed the strike at expiration.
According to the table, we could collect the most premium by selling the 110 DTE $2.5 call for $0.95. However, there is a couple problems with that option contract. We are sitting with bags at $5.15/share and receiving $0.95 will only reduce our average to $4.20/share. On expiration, if still above $2.5, then we are assigned, shares called away and we receive $2.50/share or a loss of $170 - not good.
Well, then how about the $5 strike at 110 DTE for $0.50? This reduces us to $4.65/share which is under the $5 strike so we would make a profit of $35! This is true - however 110 days is a long time to make $35. You might say that is fine you just want to get the bags gone don't care. Well maybe consider a shorter DTE - even the 20 DTE or 50 DTE would collect premium that reduces your average below $5. This would allow you to react to any stock movement that occurs in the near-term.
Consider person A sells the 110 DTE $5 call and person B sells the 50 DTE $5 call. Suppose that the XYZ stock increases to $4.95/share in 50 days then goes to $8 in the next 30 days then drops to $3 after another 30 days. This timeline goes 110 days and person A had to watch the price go up and fall back to the same spot with XYZ stock at $3/share. Granted the premium collected reduced the average but stilling hold the bags. Person B on the other hand has the call expire worthless when XYZ is at $4.95/share. A decision can be made - sell immediately, sell another $5 call or sell a $7.5 call. Suppose the $7.5 call is sold with 30 DTE collecting some premium, then - jackpot - the shares are called away when XYZ is trading at $8/share! Of course, no one can predict the future, but the shorter DTE enables more decision points.
The takeaway for the second step in the 2-stage approach is that you need to select your profit target to help guide your strike selection. In this example, are you happy with the XYZ shares called away at $5/share or do you want $7.5/share? What is your opinion on the stock price trajectory? When do you foresee decision points? This will help determine the strike/expiration that matches your thoughts. Note: studies have shown that actively managing your position results in better performance than simply waiting for expiration, so you can adjust the position if your assessment on the movement is incorrect.
Let's circle back to the first step "reduce the average cost". What if your average cost of your 100 shares of XYZ is $8/share? Clearly, all of the strikes in our example option chain above is "bad" to a certain extent since we would stand to lose a lot of money if the option contract is exercised. However, by describing the second step, we know the objective for this first step is to reduce our average such that we can profit from the strikes. How do we achieve this objective?
It is somewhat the same process as previously described, but you need to do your homework a little more diligently. What is your forecast on the stock movement? Since $7.5 is the closest strike to your average, when do you expect XYZ to rise from $3/share to $7.5/share? Without PR, you might say never. With some PR then maybe 50/50 chance - if so, then what is the outlook for PR? What do you think the chances of going to $5/share where you could collect more premium?
Suppose that a few XYZ bag holders (all with a $8/share cost) discuss there outlook of the XYZ stock price in the next 120 days:
Person 10 days 20 days 30 days 40 days 50 days 100 days 120 days
A $3 $3 $3 $3 $3 $4 $4
B $4 $4 $5 $6 $7 $12 $14
C $7 $7 $7 $7 $7 $7 $7
Person A does not seem to think much price movement will occur. This person might sell the $5 call with either 20 DTE or 50 DTE. Then upon expiration, sell another $5 call for another 20-50 DTE. Person A could keep repeating this until the average is reduced enough to move onto step-2. Of course, this approach is risky if the Person A price forecast is incorrect and the stock price goes up - which might result in assignment too soon.
Person B appears to be the most bullish of the group. This person might sell the $5 call with 20 DTE then upon expiration sell the $7.5 call. After expiration, Person B might decide to leave the shares uncovered because her homework says XYZ is going to explode and she wants to capture those gains!
Person C believes that there will be a step increase in 10 days maybe due to major PR event. This person will not have the chance to reduce the average in time to sell quickly, so first he sells a $7.5 call with 20 DTE to chip at the average. At expiration, Person C would continue to sell $7.5 calls until the average at the point where he can move onto the "get rid of bags" step.
In all causes, each person must form an opinion on the XYZ price movement. Of course, the prediction will be wrong at some level (otherwise they wouldn't be bag holders!).
The takeaway for the first step in the 2-stage approach is that you need to do your homework to better forecast the price movement to identify the correct strikes to bring down your average. The quality of the homework and the risk that you are willing to take will dedicate the speed at which you can reduce your average.
Note that if you are unfortunate to have an extremely high average per share, then you might need to consider doing the good old buy-more-shares-to-average-down. This will be the fastest way to reduce your average. If you cannot invest more money, then the approach above will still work, but it will require much more patience. Remember there is no free lunch!
Advanced note: there is another method to reduce your (high) average per share - selling cash secured puts. It is the "put version" of a cover call. Suppose that you sell a XYZ $2.5 put contract for $0.50 with 60 DTE. You collect $50 from the premium of the contract. This money is immediately in your bank and reduces your investment cost. But what did you sell? If XYZ is trading below $2.50, then you will be assigned 100 shares of XYZ at $2.50/share or $250. You own more shares, but at a price which will reduce your average further. Being cash secured, your brokerage will reserve $250 from your account when you sell the contract. In essence, you reduce your buying power by $250 and conditionally purchase the shares - you do not have them until assignment. If XYZ is greater than the strike at expiration, then your broker gives back $250 cash / buying power and you keep the premium.

Early assignment - one concern is the chance of early assignment. The American style option contract allows the holder the opportunity to exercise the contract at any time prior to expiration. Early assignment almost never occurs. There are special cases that typically deal with dividends but most penny stocks are not in the position to hand out dividends. Aside from that, the holder would be throwing away option time value by early exercise. It possibly can handle - probably won't - it actually would be a benefit when selling covered calls as you would receive your profit more quickly!

Step-by-Step Guide for Adding a Stack, Expanding Control Lines, and Building an Assembler

After the positive response to my first tutorial on expanding the RAM, I thought I'd continue the fun by expanding the capabilities of Ben's 8-bit CPU even further. That said, you'll need to have done the work in the previous post to be able to do this. You can get a sense for what we'll do in this Imgur gallery.
In this tutorial, we'll balance software and hardware improvements to make this a pretty capable machine:

Parts List

To only update the hardware, you'll need:
If you want to update the toolchain, you'll need:
  1. Arduino Mega 2560 (Amazon) to create the programmer.
  2. Ribbon Jumper Cables (Amazon) to connect the Arduino to the breadboard.
  3. TL866 II Plus EEPROM Programmer (Amazon) to program the ROM.
Bonus Clock Improvement: One additional thing I did is replace the 74LS04 inverter in Ben's clock circuit with a 74LS14 inverting Schmitt trigger (datasheet, Jameco). The pinouts are identical! Just drop it in, wire the existing lines, and then run the clock output through it twice (since it's inverting) to get a squeaky clean clock signal. Useful if you want to go even faster with the CPU.

Step 1: Program with an Arduino and Assembler (Image 1, Image 2)

There's a certain delight in the physical programming of a computer with switches. This is how Bill Gates and Paul Allen famously programmed the Altair 8800 and started Microsoft. But at some point, the hardware becomes limited by how effectively you can input the software. After upgrading the RAM, I quickly felt constrained by how long it took to program everything.
You can continue to program the computer physically if you want and even after upgrading that option is still available, so this step is optional. There's probably many ways to approach the programming, but this way felt simple and in the spirit of the build. We'll use an Arduino Mega 2560, like the one in Ben's 6502 build, to program the RAM. We'll start with a homemade assembler then switch to something more robust.
Preparing the Physical Interface
The first thing to do is prepare the CPU to be programmed by the Arduino. We already did the hard work on this in the RAM upgrade tutorial by using the bus to write to the RAM and disconnecting the control ROM while in program mode. Now we just need to route the appropriate lines to a convenient spot on the board to plug the Arduino into.
  1. This is optional, but I rewired all the DIP switches to have ground on one side, rather than alternating sides like Ben's build. This just makes it easier to route wires.
  2. Wire the 8 address lines from the DIP switch, connecting the side opposite to ground (the one going to the chips) to a convenient point on the board. I put them on the far left, next to the address LEDs and above the write button circuit.
  3. Wire the 8 data lines from the DIP switch, connecting the side opposite to ground (the one going to the chips) directly below the address lines. Make sure they're separated by the gutter so they're not connected.
  4. Wire a line from the write button to your input area. You want to connect the side of the button that's not connected to ground (the one going to the chip).
So now you have one convenient spot with 8 address lines, 8 data lines, and a write line. If you want to get fancy, you can wire them into some kind of connector, but I found that ribbon jumper cables work nicely and keep things tidy.
The way we'll program the RAM is to enter program mode and set all the DIP switches to the high position (e.g., 11111111). Since the switches are upside-down, this means they'll all be disconnected and not driving to ground. The address and write lines will simply be floating and the data lines will be weakly pulled up by 1k resistors. Either way, the Arduino can now drive the signals going into the chips using its outputs.
Creating the Arduino Programmer
Now that we can interface with an Arduino, we need to write some software. If you follow Ben's 6502 video, you'll have all the knowledge you need to get this working. If you want some hints and code, see below (source code):
  1. Create arrays for your data and address lines. For example: const char ADDRESS_LINES[] = {39, 41, 43, 45, 47, 49, 51, 53};. Create your write line with #define RAM_WRITE 3.
  2. Create functions to enable and disable your address and data lines. You want to enable them before writing. Make sure to disable them afterward so that you can still manually program using DIP switches without disconnecting the Arduino. The code looks like this (just change INPUT to OUTPUT accordingly): for(int n = 0; n < 8; n += 1) { pinMode(ADDRESS_LINES[n], OUTPUT); }
  3. Create a function to write to an address. It'll look like void writeData(byte writeAddress, byte writeData) and basically use two loops, one for address and one for data, followed by toggling the write.
  4. Create a char array that contains your program and data. You can use #define to create opcodes like #define LDA 0x01.
  5. In your main function, loop through the program array and send it through writeData.
With this setup, you can now load multi-line programs in a fraction of a second! This can really come in handy with debugging by stress testing your CPU with software. Make sure to test your setup with existing programs you know run reliably. Now that you have your basic setup working, you can add 8 additional lines to read the bus and expand the program to let you read memory locations or even monitor the running of your CPU.
Making an Assembler
The above will serve us well but it's missing a key feature: labels. Labels are invaluable in assembly because they're so versatile. Jumps, subroutines, variables all use labels. The problem is that labels require parsing. Parsing is a fun project on the road to a compiler but not something I wanted to delve into right now--if you're interested, you can learn about Flex and Bison. Instead, I found a custom assembler that lets you define your CPU's instruction set and it'll do everything else for you. Let's get it setup:
  1. If you're on Windows, you can use the pre-built binaries. Otherwise, you'll need to install Rust and compile via cargo build.
  2. Create a file called 8bit.cpu and define your CPU instructions (source code). For example, LDA would be lda {address} -> 0x01 @ address[7:0]. What's cool is you can also now create the instruction's immediate variant instead of having to call it LDI: lda #{value} -> 0x05 @ value[7:0].
  3. You can now write assembly by adding #include "8bit.cpu" to the top of your code. There's a lot of neat features so make sure to read the documentation!
  4. Once you've written some assembly, you can generate the machine code using ./customasm yourprogram.s -f hexc -p. This prints out a char array just like our Arduino program used!
  5. Copy the char array into your Arduino program and send it to your CPU.
At this stage, you can start creating some pretty complex programs with ease. I would definitely play around with writing some larger programs. I actually found a bug in my hardware that was hidden for a while because my programs were never very complex!

Step 2: Expand the Control Lines (Image)

Before we can expand the CPU any further, we have to address the fact we're running out of control lines. An easy way to do this is to add a 3rd 28C16 ROM and be on your way. If you want something a little more involved but satisfying, read on.
Right now the control lines are one hot encoded. This means that if you have 4 lines, you can encode 4 states. But we know that a 4-bit binary number can encode 16 states. We'll use this principle via 74LS138 decoders, just like Ben used for the step counter.
Choosing the Control Line Combinations
Everything comes with trade-offs. In the case of combining control lines, it means the two control lines we choose to combine can never be activated at the same time. We can ensure this by encoding all the inputs together in the first 74LS138 and all the outputs together in a second 74LS138. We'll keep the remaining control lines directly connected.
Rewiring the Control Lines
If your build is anything like mine, the control lines are a bit of a mess. You'll need to be careful when rewiring to ensure it all comes back together correctly. Let's get to it:
  1. Place the two 74LS138 decoders on the far right side of the breadboard with the ROMs. Connect them to power and ground.
  2. You'll likely run out of inverters, so place a 74LS04 on the breadboard above your decoders. Connect it to power and ground.
  3. Carefully take your inputs (MI, RI, II, AI, BI, J) and wire them to the outputs of the left 74LS138. Do not wire anything to O0 because that's activated by 000 which won't work for us!
  4. Carefully take your outputs (RO, CO, AO, EO) and wire them to the outputs of the right 74LS138. Remember, do not wire anything to O0!
  5. Now, the 74LS138 outputs are active low, but the ROM outputs were active high. This means you need to swap the wiring on all your existing 74LS04 inverters for the LEDs and control lines to work. Make sure you track which control lines are supposed to be active high vs. active low!
  6. Wire E3 to power and E2 to ground. Connect the E1 on both 138s together, then connect it to the same line as OE on your ROMs. This will ensure that the outputs are disabled when you're in program mode. You can actually take off the 1k pull-up resistors from the previous tutorial at this stage, because the 138s actively drive the lines going to the 74LS04 inverters rather than floating like the ROMs.
At this point, you really need to ensure that the massive rewiring job was successful. Connect 3 jumper wires to A0-A2 and test all the combinations manually. Make sure the correct LED lights up and check with a multimeteoscilloscope that you're getting the right signal at each chip. Catching mistakes at this point will save you a lot of headaches! Now that everything is working, let's finish up:
  1. Connect A0-A2 of the left 74LS138 to the left ROM's A0-A2.
  2. Connect A0-A2 of the right 74LS138 to the right ROM's A0-A2.
  3. Distribute the rest of the control signals across the two ROMs.
Changing the ROM Code
This part is easy. We just need to update all of our #define with the new addresses and program the ROMs again. For clarity that we're not using one-hot encoding anymore, I recommend using hex instead of binary. So instead of #define MI 0b0000000100000000, we can use #define MI 0x0100, #define RI 0x0200, and so on.
Testing
Expanding the control lines required physically rewiring a lot of critical stuff, so small mistakes can creep up and make mysterious errors down the road. Write a program that activates each control line at least once and make sure it works properly! With your assembler and Arduino programmer, this should be trivial.
Bonus: Adding B Register Output
With the additional control lines, don't forget you can now add a BO signal easily which lets you fully use the B register.

Step 3: Add a Stack (Image 1, Image 2)

Adding a stack significantly expands the capability of the CPU. It enables subroutines, recursion, and handling interrupts (with some additional logic). We'll create our stack with an 8-bit stack pointer hard-coded from $0100 to $01FF, just like the 6502.
Wiring up the Stack Pointer
A stack pointer is conceptually similar to a program counter. It stores an address, you can read it and write to it, and it increments. The only difference between a stack pointer and a program counter is that the stack pointer must also decrement. To create our stack pointer, we'll use two 74LS193 4-bit up/down binary counters:
  1. Place a 74LS00 NAND gate, 74LS245 transceiver, and two 74LS193 counters in a row next to your output register. Wire up power and ground.
  2. Wire the the Carry output of the right 193 to the Count Up input of the left 193. Do the same for the Borrow output and Count Down input.
  3. Connect the Clear input between the two 193s and with an active high reset line. The B register has one you can use on its 74LS173s.
  4. Connect the Load input between the two 193s and to a new active low control line called SI on your 74LS138 decoder.
  5. Connect the QA-QD outputs of the lower counter to A8-A5 and the upper counter to A4-A1. Pay special attention because the output are in a weird order (BACD) and you want to make sure the lower A is connected to A8 and the upper A is connected to A4.
  6. Connect the A-D inputs of the lower counter to B8-B5 and the upper counter to B4-B1. Again, the inputs are in a weird order and on both sides of the chip so pay special attention.
  7. Connect the B1-B8 outputs of the 74LS245 transceiver to the bus.
  8. On the 74LS245 transceiver, connect DIR to power (high) and connect OE to a new active low control line called SO on your 74LS138 decoder.
  9. Add 8 LEDs and resistors to the lower part of the 74LS245 transceiver (A1-A8) so you can see what's going on with the stack pointer.
Enabling Increment & Decrement
We've now connected everything but the Count Up and Count Down inputs. The way the 74LS193 works is that if nothing is counting, both inputs are high. If you want to increment, you keep Count Down high and pulse Count Up. To decrement, you do the opposite. We'll use a 74LS00 NAND gate for this:
  1. Take the clock from the 74LS08 AND gate and make it an input into two different NAND gates on the 74LS00.
  2. Take the output from one NAND gate and wire it to the Count Up input on the lower 74LS193 counter. Take the other output and wire it to the Count Down input.
  3. Wire up a new active high control line called SP from your ROM to the NAND gate going into Count Up.
  4. Wire up a new active high control line called SM from your ROM to the NAND gate going into Count Down.
At this point, everything should be working. Your counter should be able to reset, input a value, output a value, and increment/decrement. But the issue is it'll be writing to $0000 to $00FF in the RAM! Let's fix that.
Accessing Higher Memory Addresses
We need the stack to be in a different place in memory than our regular program. The problem is, we only have an 8-bit bus, so how do we tell the RAM we want a higher address? We'll use a special control line to do this:
  1. Wire up an active high line called SA from the 28C16 ROM to A8 on the Cypress CY7C199 RAM.
  2. Add an LED and resistor so you can see when the stack is active.
That's it! Now, whenever we need the stack we can use a combination of the control line and stack pointer to access $0100 to $01FF.
Updating the Instruction Set
All that's left now is to create some instructions that utilize the stack. We'll need to settle some conventions before we begin:
If you want to add a little personal flair to your design, you can change the convention fairly easily. Let's implement push and pop (source code):
  1. Define all your new control lines, such as #define SI 0x0700 and #define SO 0x0005.
  2. Create two new instructions: PSH (1011) and POP (1100).
  3. PSH starts the same as any other for the first two steps: MI|CO and RO|II|CE. The next step is to put the contents of the stack pointer into the address register via MI|SO|SA. Recall that SA is the special control line that tells the memory to access the $01XX bank rather than $00XX.
  4. We then take the contents of AO and write it into the RAM. We can also increment the stack pointer at this stage. All of this is done via: AO|RI|SP|SA, followed by TR.
  5. POP is pretty similar. Start off with MI|CO and RO|II|CE. We then need to take a cycle and decrement the stack pointer with SM. Like with PSH, we then set the address register with MI|SO|SA.
  6. We now just need to output the RAM into our A register with RO|AI|SA and then end the instruction with TR.
  7. Updating the assembler is easy since neither instruction has operands. For example, push is just psh -> 0x0B.
And that's it! Write some programs that take advantage of your new 256 byte stack to make sure everything works as expected.

Step 4: Add Subroutine Instructions (Image)

The last step to complete our stack is to add subroutine instructions. This allows us to write complex programs and paves the way for things like interrupt handling.
Subroutines are like a blend of push/pop instructions and a jump. Basically, when you want to call a subroutine, you save your spot in the program by pushing the program counter onto the stack, then jumping to the subroutine's location in memory. When you're done with the subroutine, you simply pop the program counter value from the stack and jump back into it.
We'll follow 6502 conventions and only save and restore the program counter for subroutines. Other CPUs may choose to save more state, but it's generally left up to the programmer to ensure they're not wiping out states in their subroutines (e.g., push the A register at the start of your subroutine if you're messing with it and restore it before you leave).
Adding an Extra Opcode Line
I've started running low on opcodes at this point. Luckily, we still have two free address lines we can use. To enable 5-bit opcodes, simply wire up the 4Q output of your upper 74LS173 register to A7 of your 28C16 ROM (this assumes your opcodes are at A3-A6).
Updating the ROM Writer
At this point, you simply need to update the Arduino writer to support 32 instructions vs. the current 16. So, for example, UCODE_TEMPLATE[16][8] becomes UCODE_TEMPLATE[32][8] and you fill in the 16 new array elements with nop. The problem is that the Arduino only has so much memory and with the way Ben's code is written to support conditional jumps, it starts to get tight.
I bet the code can be re-written to handle this, but I had a TL866II Plus EEPROM programmer handy from the 6502 build and I felt it would be easier to start using that instead. Converting to a regular C program is really simple (source code):
  1. Copy all the #define, global const arrays (don't forget to expand them from 16 to 32), and void initUCode(). Add #include and #include to the top.
  2. In your traditional int main (void) C function, after initializing with initUCode(), make two arrays: char ucode_upper[2048] and char ucode_lower[2048].
  3. Take your existing loop code that loops through all addresses: for (int address = 0; address < 2048; address++).
  4. Modify instruction to be 5-bit with int instruction = (address & 0b00011111000) >> 3;.
  5. When writing, just write to the arrays like so: ucode_lower[address] = ucode[flags][instruction][step]; and ucode_upper[address] = ucode[flags][instruction][step] >> 8;.
  6. Open a new file with FILE *f = fopen("rom_upper.hex", "wb");, write to it with fwrite(ucode_upper, sizeof(char), sizeof(ucode_upper), f); and close it with fclose(f);. Repeat this with the lower ROM too.
  7. Compile your code using gcc (you can use any C compiler), like so: gcc -Wall makerom.c -o makerom.
Running your program will spit out two binary files with the full contents of each ROM. Writing the file via the TL866II Plus requires minipro and the following command: minipro -p CAT28C16A -w rom_upper.hex.
Adding Subroutine Instructions
At this point, I cleaned up my instruction set layout a bit. I made psh and pop 1000 and 1001, respectively. I then created two new instructions: jsr and rts. These allow us to jump to a subroutine and returns from a subroutine. They're relatively simple:
  1. For jsr, the first three steps are the same as psh: MI|CO, RO|II|CE, MI|SO|SA.
  2. On the next step, instead of AO we use CO to save the program counter to the stack: CO|RI|SP|SA.
  3. We then essentially read the 2nd byte to do a jump and terminate: MI|CO, RO|J.
  4. For rts, the first four steps are the same as pop: MI|CO, RO|II|CE, SM, MI|SO|SA.
  5. On the next step, instead of AI we use J to load the program counter with the contents in stack: RO|J|SA.
  6. We're not done! If we just left this as-is, we'd jump to the 2nd byte of jsr which is not an opcode, but a memory address. All hell would break loose! We need to add a CE step to increment the program counter and then terminate.
Once you update the ROM, you should have fully functioning subroutines with 5-bit opcodes. One great way to test them is to create a recursive program to calculate something--just don't go too deep or you'll end up with a stack overflow!

Conclusion

And that's it! Another successful upgrade of your 8-bit CPU. You now have a very capable machine and toolchain. At this point I would have a bunch of fun with the software aspects. In terms of hardware, there's a number of ways to go from here:
  1. Interrupts. Interrupts are just special subroutines triggered by an external line. You can make one similar to how Ben did conditional jumps. The only added complexity is the need to load/save the flags register since an interrupt can happen at any time and you don't want to destroy the state. Given this would take more than 8 steps, you'd also need to add another line for the step counter (see below).
  2. ROM expansion. At this point, address lines on the ROM are getting tight which limits any expansion possibilities. With the new approach to ROM programming, it's trivial to switch out the 28C16 for the 28C256 that Ben uses in the 6502. These give you 4 additional address lines for flags/interrupts, opcodes, and steps.
  3. LCD output. At this point, adding a 16x2 character LCD like Ben uses in the 6502 is very possible.
  4. Segment/bank register. It's essentially a 2nd memory address register that lets you access 256-byte segments/banks of RAM using bank switching. This lets you take full advantage of the 32K of RAM in the Cypress chip.
  5. Fast increment instructions. Add these to registers by replacing 74LS173s with 74LS193s, allowing you to more quickly increment without going through the ALU. This is used to speed up loops and array operations.

“Sarah said you wanted to speak with me?” I strode into Zafir’s office and closed the door behind me. He looked mildly surprised to see me at first, but a welcoming smile took over soon after.
“Yes…we have much to discuss.” Zafir watched me carefully as I sat across from him. “First and foremost, I should inform you of Abel’s lie and the steps I took to fix what he’d done.”
“Oh lovely. I can’t wait.” I leaned against the armrest. “Do tell me of your noble deeds, o’ great hero.”
A short laugh escaped Zafir before he settled back in his seat, hands steepled in his lap, and his voice becoming all business. “To the point it is. Abel, contrary to his reports to me and what he told you, had you fitted with the manner of brain chip that can be detonated. The military recently began investigating Abel’s activities due to his sudden—classified—disappearance. As much of his misconduct was in relation to the other survivors, I took the liberty of ordering additional scans when you were rendered unconscious.”
I gave him an impatient look when he paused for a swig of water. “Which showed the chip. And?”
“I took the liberty of replacing it. After some discussions with our bosses, I educated them on the nuances of survivors such as yourself and acquired permission to use a Syldrari-made chip.” Zafir gave me that mysterious ‘I know you’re overthinking every word I say’ smile of his. “The survivors, and especially you, require more processing power than the empire’s chips provide. Luckily for us, the empire has no qualms about stealing technology from others and refitting it to suit their own purposes.”
“Why Syldrari specifically?” I raised an eyebrow. “There’s plenty of races more advanced than us.”
“Because the Syldrari are the most advanced species we’ve encountered, and because a Syldrari chip was the only one you showed compatibility with. I imagine it must have something to do with the Resonance Incident and your Syldrari suit.” Zafir shrugged, seemingly unbothered by my suspicion. “With that explained, we come to the primary reason I sent for you: I want your permission to run further tests. I’m not confident that Abel didn’t fake more information. Specifically, I would like to run blood tests.”
“I mean…fine?” I glanced around, then back at Zafir. “Here, or one of the labs?”
“Here will suffice.” Zafir motioned for me to roll up my sleeves. He stood and began rummaging around in the nearby cabinets. “How is training progressing?”
“It’s…going. There’s not really much to say on that front until they can start actually going out to do…whatever it is we do.” I shook my head.
“I’m still waiting to hear back from our bosses, but I did send in my request that Calder, Nikolai, and Maelor begin working.” Zafir pulled a chair up next to me and rolled a tray over, motioning for me to give him my arm. “Speaking of which, they want you to resume patrolling the Syldrari Sector during the day. They believe we’ve given enough time—”
“I’m not so sure about that,” I interjected, thinking back to the letter Sarah had brought to me from Rel. “From what I understand, the Syldrari are worryingly convinced that I’m Lethe, and it may be dangerous for me there because of it.”
“And you have this on good authority?” Zafir inquired as he gently prodded at my arm, sanitizing it before strapping a thin black band around the crook of my elbow.
I grimaced. It was too late not to elaborate. “Rel sent a letter along with our meal the other week. He warned that I should stay away because multiple clans, including the R’selkti, are looking for me due to these rumors.”
“Of course…” Zafir sighed, his expression falling. “I’m afraid there’s nothing I can say at this point to make them reconsider…without putting you at greater risk. Tomorrow you will begin your patrols again. I will see if I can convince our superiors to permit one of your colleagues to join you. Either way, I am planning to have one of them act as our ‘vigilante’ in the sector for a time, while you work elsewhere. Who would you say is the most stable?”
“Nikolai for sure.” I raised an eyebrow as Zafir took the band off me. “Done already?”
“Indeed. It’s much more efficient than a needle.” Zafir tilted a black glass vial, peering into it briefly before capping it off. The other three were quickly sealed as well. If there was anything off about my blood, he didn’t comment or show it. A pity, that. I was curious to know if there were still traces of blue like I’d seen while fighting the odd Syldrari. “Now then, I recommend you rest for the remainder of the day. I want you at your best when dealing with the Syldrari. Perhaps you can do some reading on their culture while you relax?”
* * *
I arrived in the Syldrari Sector early in the morning as shops were starting to open and people were beginning to walk the streets. Though it was early, there seemed to be an unusual number of people out and about. They were all so distracted that I managed to make it all the way to Rel’s cafe without anyone acknowledging my presence.
“Elara? You shouldn’t…” Rel released an aggravated sigh. “You don’t have a choice and that’s why you’re here. Of course. What can I do for you, then? Are you feeling better?”
“Better…ish?” I shrugged and gave him a small smile. “What can I say? It’s one thing after another. I’m just trying to roll with the punches at this point.”
“Understandable.” Rel nodded and gave me a tired smile. “Will I be surprising you again today?”
“Can you stop spoiling the graekstidat fodder for one second?” A familiar, grumpy voice demanded. I glanced over to see a Syldrari man with pale grey skin walking over. His black hair obscured one eye, the pale blue underside glowing against his cheek. His eyes were…among the odder that I’d seen. While the pupils were consistent with Syldrari, the colors of deep mauve, yellow, and jade green blended together similar to how a human’s hazel did.
However, I had no damn idea where I’d heard his voice before.
“A…what fodder?” I looked over at the aggravated Rel. “And since when did you have an edgy teenager working for you?”
“Ah, think of it as an amphibious, furred shark hybrid the length of…several train cars,” Rel answered, pressing his fingers to his temples. “Furthermore, Aldiner is old enough to be your great-great-great-”
“I’m working here to pay up for pissing off the elder here,” Aldiner interjected with a snort as he pushed his hands into his apron pockets. He leaned over me, examining me from a few angles. “You don’t have that military air to you. Sure you’re a—”
I gave Aldiner my best cold, intimidating glare as he reached out and poked my cheek once. When he went for a second poke, I knocked his arm aside, spun behind him and elbowed him where I hoped his kidneys were, and moved to take him down to the ground. Alas, an arm wrapped around my waist and lifted me clean off the floor—and didn’t stop until my butt was planted on his shoulder. I looked down, startled enough to forget about beating the crap out of Aldiner.
“Ignore Aldiner. He likes to annoy everyone he sees, and hates being ignored.” The much larger Syldrari glanced at me. I certainly hadn’t expected it to be the grumpy soldier man, seeing as he’d appeared to rather dislike me. “You’re fast, for a strigaella.”
“A human woman,” Rel answered my next question with a sigh. Aldiner, behave. Humans are much less…ah…” Rel motioned with his hands and wiggled his fingers as he searched for the word.
“You don’t touch humans unless invited to,” the soldier Syldrari grunted.
“She invited ya?” Aldiner leaned forward peering at the soldier and then at where I was perched on his shoulder.
“I didn’t, but I can appreciate that he was stopping me from starting a brawl with you right here and—” I cut myself off with an aggravated sigh when felt the feral attempting to push forward. All three Syldrari went still and watched me warily. What they sensed, or how much, I wasn’t sure I wanted to know. “Set me down, please…uh…”
“Heh, always bitching about manners and you never introduced yourself, did ya?” Aldiner gave the soldier a cocky grin.
“…call me Casair,” the soldier glanced away, seeming a little disgruntled, but the patterns of light on his arms didn’t so much as flicker.
…Aldiner on the other hand… I glanced at the self-contained rave fish, then back at Casair. “And you can call me Elara, though I suppose you knew that already.”
“Awww, Casair is shy!” Aldiner teased. “Suppressing—”
“Quiet, vlerst bait.” Casair crossed his arms at the strobing Syldrari, then glanced over at me. “Back to patrolling needlessly?”
“Something like that. I was sitting around recovering for so long that my boss’s bosses started thinking up other uses for me.” I grimaced before walking over to the counter and hopping up onto my usual seat. “As for surprising me, Rel, yes. Though I’d like a glass of…” I paused to reference the menu, “Jiirst☆nil?”
Either I said it very right or terribly wrong, because all three men stopped what they were doing to stare at me in shock. Well, Aldiner was staring already, but he didn’t count.
“Ah, there you are Rel my dear!” A woman’s voice carried through the room shortly after I heard the doors to the establishment open. “I’ve been looking everywhere for you!”
“Mother, please…” a familiar voice groaned, and I glanced back to see the candy girl—who perked up and waved when she spotted me.
“Careful you don’t become the queen’s snack,” Casair muttered by my ear before moving away to a booth in the corner, settling into it in such a way that he could keep an eye on everyone.
Queen? I eyed the flamboyant woman and the three people with her. If one was her daughter, I had to assume the other two were guards—they had weapons holstered at their hips, at least.
“I’m honored by your visit, but please refrain—” Rel began.
“So, when will you become one of my consorts?” The…queen? demanded with a bright smile—one that faltered when Rel placed the drink he was making in front of me instead of her. I half-expected her to be angry, but instead she studied me for a moment, her head tilted, and a finger pressed against her full, black-painted lips. “A visitor in the Syldrari Sector…are you an Iri, Sen’iri, Sol’iri, Anad’iri, Sora’iri, or Lun’iri? I can never tell with you humans…”
“Elara is an Iri, honestly…” Rel rubbed his temples. “How many times must we explain to you that the humans are binary in their biological—”
“And that is just the problem! Biological! If they didn’t hop around between bodies and swap out prosthetics constantly—no offense—perhaps I could more easily identify who they are!” The queen hmphed, crossed her arms, then finally seemed to spot my uniform. “Ah, a military girl—my favorite. If Rel still refuses to become my consort… How would you like off this planet, sweetie?”
“Mother, please!” The candy girl moved between her mother and me. “Elara is the nice human I told you about! She likes the candy I make, and her friends are going to help give me ideas for ones more humans will like! Plus, you haven’t even introduced yourself! Humans can’t sense a queen’s identity!”
“Speaking of my colleagues,” I paused, pulling out several sheets of paper that had been folded together. “They may not be able to come to the sector for a while, so they asked me to deliver their notes to you.”
She took them, and skimmed the first page, the glowing sections of her skin pulsing faster the more she read. “This is…this is great! I’m going to go work on the next batch!”
And with that, the excitable candy girl darted out of the café, practically skipping as she went.
“I’m Xilen, I run the mercantile Dvarl Clan,” the queen stated promptly, offering me her hand. When I shook it, she paused to study my face and search my eyes. “If you ever want off this planet, Rel knows how to contact me. It wouldn’t do for a pretty little thing like you to be wasted on the humans.”
“…I’ll keep that in mind…” I gently reclaimed my hand while Aldiner snickered from somewhere.
“Do you find women…?” Rel raised an eyebrow when I shook my head. “Then, you are being polite.”
“I’m keeping my options open,” I countered. “If the military can’t recreate the Resonance phenomena—and maybe even if they can—their next step is going to be breeding our mutations down to offspring. I want no part of that, so having options is good.”
“Ahhh, she’s so smart!” Xilen leaned over to squeeze me, rubbing her cheek against mine. To my surprise, the Syldrari in the cafe all looked ready to start a fight over it—with her. I got the distinct feeling it wasn’t jealousy, which made me all the more confused. “You just say the word and I’ll have you off this planet and into my arms! I’d love to see how such a cute human would look in Syldrari clothes—you don’t mind translucency, do you? I’d imagine not—”
“Elara needs to have her meal before she returns to her duties.” Rel suddenly appeared behind us, his hand on the queen’s shoulder, and his voice cold as ice. “If you’re here to discuss trade, you can wait for me in the usual room.”
“How dare—” One of the men I assumed to be the queen’s guards started to raise a weapon. I figured this was as good a time as any to make my point.
I was out of my chair and twisting the weapon out of the man’s hand before he could finish his sentence. Using his body weight against him, I got him on the floor and twisted his arm behind his back, placing my booted foot against the back of his shoulders.
“You— Ugh!” The other guard grunted when Casair’s fist met his stomach.
“Please keep in mind that my job is to keep conflicts in the Syldrari Sector to a minimum, and I am authorized to use lethal force if you pull a weapon on anyone, regardless of race or species,” I spoke calmly, grinding my heel into the Syldrari’s back for emphasis. “You may keep your weapons and use them for defense if necessary. If you pull them again for any other reason…”
“Cuuute!” Xilen promptly squeezed me in a hug. It took most of my willpower to beat down the feral, especially since I agreed with the idea of fucking ripping her arms off if she hugged me one more damn time. Xilen leaned down to speak quietly by my ear, “Be careful, dear. If you ever suspect you’re in trouble or in over your head, I’m sure you know how we can get them to come running to save you. And, stay far, far away from the R’selkti and their queen.”
“Uh—?” I didn’t get to ask her what the hell she was on about. She fetched her guards and led them to some back room, leaving me confused and…a little unnerved.
“I apologize for Queen Xilen’s…eccentricities,” Rel offered when I finally turned around to return to my seat.
“Are all queens so goddamn pushy?” I snorted irritably, trying to shove Xilen’s insinuations out of my mind.
“Ah…with Iri being the rarest of the six, they tend to act however they please…” Rel murmured awkwardly. “It is not uncommon for Syldrari women to turn their rarity into a form of power over others. Most Iri, even if they are not queens, have many…I believe the human word is ‘spouses?’”
“Long story short: most recent queens have been groomed to see the other sexes as playthings to collect. Some of them even take other Iri, but it’s frowned upon,” Casair piped up flatly. “Xilen is of a different tide. She’s lasted so long because she can pretend. Whatever she whispered to you was probably as herself.”
“Blah blah blah.” Aldiner rolled his eyes before leaning toward me. “You know, being a queen’s pet has its perks.”
“Aldiner!” Rel barked, his markings flaring bright. “Go wash the dishes!
“Fiiine.” Aldiner sauntered off toward the back, though he turned and stuck his fingers up in a V and flicked his surprisingly long dual or split tongue between them before disappearing through the door.
…I have a feeling it’s a good thing Rel didn’t catch that… I shook my head slightly. “So, are there any other developments I should know about before I start my patrols again?”
“Just…be cautious. Someone has convinced the people here that you are Lethe…and that she may be a queen or related to one.” Rel sighed heavily and pushed his hair back. “Aside from that, things have been calming down after the little queen was found. With Xilen here…who knows. Her unannounced visits always cause trouble.”

Using Deep Learning to Predict Earnings Outcomes

Using Deep Learning to Predict Earnings Outcomes
(Note: if you were following my earlier posts, I wrote a note at the end of this post explaining why I deleted old posts and what changed)
Edit: Can't reply to comments since my account is still flagged as new :\. Thank you everyone for your comments. Edit: Made another post answering questions here.
  • Test data is untouched during training 10:1:1 train:val:test.
  • Yes, I consider it "deep" learning from what I learned at my institution. I use LSTMs at one point in my pipeline, feel free to consider that deep or not.
  • I'll be making daily posts so that people can follow along.
  • Someone mentioned RL, yes I plan on trying that in the future :). This would require a really clever way to encode the current state parameters. Haven't thought about it too much yet.
  • Someone mentioned how companies beat earnings 61% anyway, so my model must be useless right? Well if you look at the confusion matrix you can see I balanced classes before training (with some noise). This means that the data had roughly 50/50 beat/miss and had a 58% test accuracy.
TLDR:
Not financial advice.
  • I created a deep learning algorithm trained on 2015-2019 data to predict whether a company will beat earning estimates.
  • Algorithm has an accuracy of 58%.
  • I need data and suggestions.
  • I’ll be making daily posts for upcoming earnings.
Greetings everyone,
I’m Bunga, an engineering PhD student at well known university. Like many of you, I developed an interest in trading because of the coronavirus. I lost a lot of money by being greedy and uninformed about how to actually trade options. With all the free time I have with my research slowing down because of the virus, I’ve decided to use what I’m good at (being a nerd, data analytics, and machine learning) to help me make trades.
One thing that stuck out to me was how people make bets on earnings reports. As a practitioner of machine learning, we LOVE binary events since the problem can be reduced to a simple binary classification problem. With that being said, I sought out to develop a machine learning algorithm to predict whether a company will beat earnings estimates.
I strongly suggest TO NOT USE THIS AS FINANCIAL ADVICE. Please, I could just be a random guy on the internet making things up, and I could have bugs in my code. Just follow along for some fun and don’t make any trades based off of this information 😊
Things other people have tried:
A few other projects have tried to do this to some extent [1,2,3], but some are not directly predicting the outcome of the earnings report or have a very small sample size of a few companies.
The data
This has been the most challenging part of the project. I’m using data for 4,000 common stocks.
Open, high, low, close, volume stock data is often free and easy to come by. I use stock data during the quarter (Jan 1 – Mar 31 stock data for Q1 for example) in a time series classifier. I also incorporate “background” data from several ETFs to give the algorithm a feel for how the market is doing overall (hopefully this accounts for bull/bear markets when making predictions).
I use sentiment analyses extracted from 10K/10Q documents from the previous quarter as described in [4]. This gets passed to a multilayer perceptron neural network.
Data that I’ve tried and doesn’t work to well:
Scraping 10K/10Q manually for US GAAP fields like Assets, Cash, StockholdersEquity, etc. Either I’m not very good at processing the data or most of the tables are incomplete, this doesn’t work well. However, I recently came across this amazing API [5] which will ameliorate most of these problems, and I plan on incorporating this data sometime this week.
Results
After training on about 34,000 data points, the model achieves a 58% accuracy on the test data. Class 1 is beat earnings, Class 2 is miss earnings.. Scroll to the bottom for the predictions for today’s AMC estimates.

Future Directions
Things I’m going to try:
  • Financial twitter sentiment data (need data for this)
  • Data on options (ToS apparently has stuff that you can use)
  • Using data closer to the earnings report itself rather than just the data within the quarterly date
A note to the dozen people who were following me before
Thank you so much for the early feedback and following. I had a bug in my code which was replicating datapoints, causing my accuracy to be way higher in reality. I’ve modified some things to make the network only output a single value, and I’ve done a lot of bug fixing.
Predictions for 4/30/20 AMC:
A value closer to 1 means that the company will be more likely to beat earnings estimates. Closer to 0 means the company will be more likely to miss earnings estimates. (People familiar with machine learning will note that neural networks don’t actually output a probability distribution so the values don’t actually represent a confidence).

[Table] Asteroid Day AMA – We’re engineers and scientists working on a mission that could, one day, help save humankind from asteroid extinction. Ask us anything!

Source
There are several people answering: Paolo Martino is PM, Marco Micheli is MM, Heli Greus is HG, Detlef Koschny is DVK, and Aidan Cowley is AC.
Questions Answers
Can we really detect any asteroids in space with accuracy and do we have any real means of destroying it? Yes, we can detect new asteroids when they are still in space. Every night dozens of new asteroids are found, including a few that can come close to the Earth.
Regarding the second part of the question, the goal would be to deflect them more than destroy them, and it is technologically possible. The Hera/DART mission currently being developed by ESA and NASA will demonstrate exactly this capability.
MM
I always wanted to ask: what is worse for life on Earth - to be hit by a single coalesced asteroid chunk, or to be hit by a multiple smaller pieces of exploded asteroid, aka disrupted rubble pile scenario? DVK: This is difficult to answer. If the rubble is small (centimetres to meters) it is better to have lots of small ones – they’d create nice bright meteors. If the rubble pieces are tens of meters it doesn’t help.
Let’s say that hypothetically, an asteroid the size of Rhode Island is coming at us, it will be a direct hit - you’ve had the resources and funding you need, your plan is fully in place, everything you’ve wanted you got. The asteroid will hit in 10 years, what do you do? DVK: I had to look up how big Rhode Island is – a bit larger than the German Bundesland ‘Saarland’. Ok – this would correspond to an object about 60 km in diameter, right? That’s quite big – we would need a lot of rocket launches, this would be extremely difficult. I would pray. The good news is that we are quite convinced that we know all objects larger than just a few kilometers which come close to our planet. None of them is on a collision course, so we are safe.
the below is a reply to the above
Why are you quite convinced that you know all object of that size? And what is your approach in finding new celestial bodies? DVK: There was a scientific study done over a few years (published in Icarus 2018, search for Granvik) where they modelled how many objects there are out there. They compared this to the observations we have with the telescopic surveys. This gives us the expected numbers shown here on our infographic: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
There are additional studies to estimate the ‘completeness’ – and we think that we know everything above roughly a few km in size.
To find new objects, we use survey telescopes that scan the night sky every night. The two major ones are Catalina and Pan-STARRS, funded by NASA. ESA is developing the so-called Flyeye telescope to add to this effort https://www.esa.int/ESA_Multimedia/Images/2017/02/Flyeye_telescope.
the below is a reply to the above
Thanks for the answer, that's really interesting! It's also funny that the fist Flyeye deployed is in Sicily, at less than 100km from me, I really had no idea DVK: Indeed, that's cool. Maybe you can go and visit it one day.
the below is a reply to the original answer
What about Interstellar objects however, like Oumuamua? DVK: The two that we have seen - 'Oumuamua and comet Borisov - were much smaller than the Saarland (or Rhode Island ;-) - not sure about Borisov, but 'Oumuamua was a few hundred meters in size. So while they could indeed come as a complete surprise, they are so rare that I wouldn't worry.
Would the public be informed if an impending asteroid event were to happen? And, how would the extinction play out? Bunch of people crushed to death, knocked off our orbit, dust clouds forever? DVK: We do not keep things secret – all our info is at the web page http://neo.ssa.esa.int. The ‘risky’ objects are in the ‘risk page’. We also put info on really close approaches there. It would also be very difficult to keep things ‘under cover’ – there are many high-quality amateur astronomers out there that would notice.
In 2029 asteroid Apophis will fly really close to Earth, even closer than geostationary satellites. Can we use some of those satellites to observe the asteroid? Is it possible to launch very cheap cube sats to flyby Apophis in 2029? DVK: Yes an Apophis mission during the flyby in 2029 would be really nice. We even had a special session on that topic at the last Planetary Defense Conference in 2019, and indeed CubeSats were mentioned. This would be a nice university project – get me a close-up of the asteroid with the Earth in the background!
the below is a reply to the above
So you’re saying it was discussed and shelved? In the conference we just presented ideas. To make them happen needs funding - in the case of ESA the support of our member countries. But having something presented at a conference is the first step. One of the results of the conference was a statement to space agencies to consider embarking on such a mission. See here: https://www.cosmos.esa.int/documents/336356/336472/PDC_2019_Summary_Report_FINAL_FINAL.pdf/341b9451-0ce8-f338-5d68-714a0aada29b?t=1569333739470
Go to the section 'resolutions'. This is now a statement that scientists can use to present to their funding agencies, demonstrating that it's not just their own idea.
Thanks for doing this AMA! Did we know the Chelyabinsk meteor in 2013 (the one which had some great videos on social media) was coming? Ig not, how comes? Also, as a little side one, have there been any fatalities from impact events in the past 20 years? Unfortunately, the Chelyabinsk object was not seen in advance, because it came from the direction of the Sun where ground-based telescopes cannot look.
No known fatalities from impacts have happened in the past 20 years, although the Chelyabinsk event did cause many injuries, fortunately mostly minor.
MM
the below is a reply to the above
How often do impacts from that direction happen, compared to impacts from visible trajectories? In terms of fraction of the sky, the area that cannot be easily scanned from the ground is roughly a circle with a radius of 40°-50° around the current position of the Sun, corresponding to ~15% of the total sky. However, there is a slight enhancement of objects coming from that direction, therefore the fraction of objects that may be missed when heading towards us is a bit higher.
However, this applies only when detecting an asteroid in its "final plunge" towards the Earth. Larger asteroids can be spotted many orbits earlier, when they are farther away and visible in the night side of the sky. Their orbits can then be determined and their possible impacts predicted even years or decades in advance.
MM
There must be a trade-off when targeting asteroids as they get closer to Earth, is there a rule of thumb at what the best time is to reach them, in terms of launch time versus time to reach the asteroid and then distance from Earth? DVK: Take e.g. a ‘kinetic impactor’ mission, like what DART and Hera are testing. Since we only change the velocity of the asteroid slightly, we need to hit the object early enough so that the object has time to move away from it’s collision course. Finding out when it is possible to launch requires simulations done by our mission analysis team. They take the strength of the launcher into account, also the available fuel for course corrections, and other things. Normally each asteroid has its own best scenario.
Do you also look at protecting the moon from asteroids? Would an impact of a large enough scale potentially have major impacts on the earth? DVK: There are programmes that monitor the Moon and look for flashes from impacting small asteroids (or meteoroids) - https://neliota.astro.noa.g or the Spanish MIDAS project. We use the data to improve our knowledge about these objects. These programmes just look at what is happening now.
For now we would not do anything if we predicted a lunar impact. I guess this will change once we have a lunar base in place.
Why aren't there an international organisation comprised of countries focused on the asteroid defence? Imagine like the organisation with multi-billion $ budget and program of action on funding new telescopes, asteroid exploration mission, plans for detection of potentially dangerous NEA, protocols on action after the detection - all international, with heads of states discussing these problems? DVK: There are international entities in place, mandated by the UN: The International Asteroid Warning Network (http://www.iawn.net) and the Space Mission Planning Advisory Group (http://www.smpag.net). These groups advise the United Nations. That is exactly where we come up with plans and protocols on action. But: They don’t have budget – that needs to come from elsewhere. I am expecting that if we have a real threat, we would get the budget. Right now, we don’t have a multi-billion budget.
the below is a reply to someone else's answer
There is no actual risk of any sizable asteroids hitting earth in the foreseeable future. Any preparation for it would just be a waste of money. DVK: Indeed, as mentioned earlier, we do not expect a large object to hit is in the near future. We are mainly worried about those in the size range of 20 m to 40 m, which happen on average every few tens of years to hundreds of years. And where we only know a percent of them or even less.
President Obama wanted to send a crewed spacecraft to an asteroid - in your opinion is this something that should still be done in the future, would there be any usefulness in having a human being walk/float on an asteroid's surface? DVK: It would definitely be cool. I would maybe even volunteer to go. Our current missions to asteroids are all robotic, the main reason is that it is much cheaper (but still expensive) to get the same science. But humans will expand further into space, I am sure. If we want to test human exploration activities, doing this at an asteroid would be easier than landing on a planet.
this is another reply Yes, but I am slightly biased by the fact that I work at the European astronaut centre ;) There exist many similarities to what we currently do for EVA (extra vehicular activities) operations on the International Space Station versus how we would 'float' around an asteroid. Slightly biased again, but using such a mission to test exploration technologies would definitely still have value. Thanks Obama! - AC
I've heard that some asteroids contains large amounts of iron. Is there a possibility that we might have "space mines" in the far away future, if our own supply if iron runs out? Yes, this is a topic in the field known as space mining, part of what we call Space Resources. In fact, learning how we can process material we might find on asteroids or other planetary bodies is increasingly important, as it opens up the opportunities for sustainable exploration and commercialization. Its a technology we need to master, and asteroids can be a great target for testing how we can create space mines :) - AC
By how much is DART expected to deflect Didymos? Do we have any indication of the largest size of an asteroid we could potentially deflect? PM: Didymos is a binary asteroid, consisting of a main asteroid Didymos A (~700m) and a smaller asteroid Didymos B (~150m) orbiting around A with a ~12 hours period. DART is expected to impact Didymos B and change its orbital period w.r.t. Didymos A of ~1%. (8 mins)
The size of Didymos B is the most representative of a potential threat to Earth (the highest combination of probability and consequence of impacts), meaning smaller asteroids hit the Earth more often but have less severe consequences, larger asteroids can have catastrophic consequences but their probability of hitting the earth is very very low.
the below is a reply to the above
Why is there less probability of larger asteroids hitting earth? DVK: There are less large objects out there. The smaller they are, the more there are.
the below is a reply to the original answer
Is there any chance that your experiment will backfire and send the asteroid towards earth? PM: Not at all, or we would not do that :) Actually Dimorphos (the Didymos "moon") will not even leave its orbit around Didymos. It will just slightly change its speed.
I'm sure you've been asked this many times but how realistic is the plot of Armageddon? How likely is it that our fate as a species will rely on (either) Bruce Willis / deep sea oil drillers? Taking into consideration that Bruce Willis is now 65 and by the time HERA is launched he will be 69, I do not think that we can rely on him this time (although I liked the movie).
HERA will investigate what method we could use to deflect asteroid and maybe the results will show that we indeed need to call the deep sea oil drillers.
HG
the below is a reply to the above
So then would it be easier to train oil drillers to become astronauts, or to train astronauts to be oil drillers? I do not know which one would be easier since I have no training/experience of deep see oil drilling nor becoming an astronaut, but as long as the ones that would go to asteroid have the sufficient skills and training (even Bruce Willis), I would be happy.
HG
If budget was no object, which asteroid would you most like to send a mission to? Nice question! For me, I'd be looking at an asteroid we know something about, since I would be interested in using it for testing how we could extract resources from it. So for me, I would choose Itokawa (https://en.wikipedia.org/wiki/25143_Itokawa), which was visited by Hayabusa spacecraft. So we already have some solid prospecting carried out for this 'roid! - AC
this is another reply Not sure if it counts as an asteroid, but Detlef and myself would probably choose ʻOumuamua, the first discovered interstellar object.
MM
the below is a reply to the above
Do we even have the capability to catch up to something like that screaming through our solar system? That thing has to have a heck of a velocity to just barrel almost straight through like that. DVK: Correct, that would be a real challenge. We are preparing for a mission called 'Comet Interceptor' that is meant to fly to an interstellar object or at least a fresh comet - but it will not catch up with it, it will only perform a short flyby.
https://www.esa.int/Science_Exploration/Space_Science/ESA_s_new_mission_to_intercept_a_comet
After proving to be able to land on one, could an asteroid serve as a viable means to transport goods and or humans throughout the solar system when the orbit of said asteroid proves beneficial. While it is probably quite problematic to land the payload, it could save fuel or am I mistaken? Neat idea! Wonder if anyone has done the maths on the amount of fuel you would need/save vs certain targets. - AC
PM: To further complement, the saving is quite marginal indeed because in order to land (softly) on the asteroid you actually need to get into the very same orbit of that asteroid . At that point your orbit remains the same whether you are on the asteroid or not..
can the current anti-ballistic missiles systems intercept a terminal phase earth strike asteroid? or it is better to know beforehand and launch an impacting vehicle into space? DVK: While I do see presentations on nuclear explosions to deflect asteroids at our professional meetings, I have not seen anybody yet studying how we could use existing missile systems. So it's hard to judge whether existing missiles would do the job. But in general, it is better to know as early as possible about a possible impact and deflect it as early as possible. This will minimize the needed effort.
How much are we prepared against asteroid impacts at this moment? DVK: 42… :-) Seriously – I am not sure how to quantify ‘preparedness’. We have international working groups in place, mentioned earlier (search for IAWN, SMPAG). We have a Planetary Defence Office at ESA, a Planetary Defense Office at NASA (who spots the difference?), search the sky for asteroids, build space missions… Still we could be doing more. More telescopes to find the object, a space-based telescope to discover those that come from the direction of the Sun. Different test missions would be useful, … So there is always more we could do.
Have you got any data on the NEO coverage? Is there estimations on the percentage of NEOs we have detected and are tracking? How can we improve the coverage? How many times have asteroids been able to enter earths atmosphere without being detected beforehand? Here’s our recently updated infographics with the fraction of undiscovered NEOs for each size range: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
As expected, we are now nearly complete for the large ones, while many of the smaller ones are still unknown.
In order to improve coverage, we need both to continue the current approach, centered on ground-based telescopes, and probably also launch dedicated telescopes to space, to look at the fraction of the sky that cannot be easily observed from the ground (e.g., towards the Sun).
Regarding the last part of your question, small asteroids enter the Earth atmosphere very often (the infographics above gives you some numbers), while larger ones are much rarer.
In the recent past, the largest one to enter our atmosphere was about 20 meters in diameter, and it caused the Chelyabinsk event in 2013. It could not be detected in advance because it came from the direction of the Sun.
We have however detected a few small ones before impact. The first happened in 2008, when a ~4-meter asteroid was found to be on a collision course less than a day before impact, it was predicted to fall in Northern Sudan, and then actually observed falling precisely where (and when) expected.
MM
this is another reply >After
DVK: And to add what MM said - Check out http://neo.ssa.esa.int. There is a ‘discovery statistics’ section which provides some of the info you asked about. NASA is providing similar information here https://cneos.jpl.nasa.gov/stats/. To see the sky which is currently covered by the survey telescopes, you need to service of the Minor Planet Center which we all work together with: http://www.minorplanetcenter.org, ‘observers’, ‘sky coverage’. That is a tool we use to plan where we look with our telescopes, so it is a more technical page.
Are there any automatic systems for checking large numbers of asteroids orbits, to see if the asteroid's orbit is coming dangerously close to Earth, or is it done by people individually for every asteroid? I ask it because LSST Rubin is coming online soon and you know it will discover a lot of new asteroids. Yes, such systems exist, and monitor all known and newly discovered asteroids in order to predict possible future impacts.
The end result of the process is what we call "risk list": http://neo.ssa.esa.int/risk-page
It is automatically updated every day once new observational data is processed.
MM
What are your favourite sci-fi series? DVK: My favorites are ‘The Expanse’, I also liked watching ‘Salvation’. For the first one I even got my family to give me a new subscription to a known internet streaming service so that I can see the latest episodes. I also loved ‘The Jetsons’ and ‘The Flintstones’ as a kid. Not sure the last one counts as sci-fi though. My long-time favorite was ‘Dark Star’.
this is another reply Big fan of The Expanse at the moment. Nice, hard sci-fi that has a good impression of being grounded in reality - AC
this is another reply When I was a kid I liked The Jetsons, when growing up Star Trek, Star wars and I also used to watch with my sister the 'V'.
HG
When determining the potential threat of a NEA, is the mass of an object a bigger factor or size? I'm asking because I'm curious if a small but massive object (say, with the density of Psyche) could survive atmospheric entry better than a comparatively larger but less massive object. The mass is indeed what really matters, since it’s directly related with the impact energy.
And as you said composition also matters, a metal object would survive atmospheric entry better, not just because it’s heavier, but also because of its internal strength.
MM
What are your thoughts on asteroid mining as portrayed in sci-fi movies? Is it feasible? If so would governments or private space programs be the first to do so?What type of minerals can be found on asteroids that would merit the costs of extraction? Certainly there is valuable stuff you can find on asteroids. For example, the likely easiest material you can harvest from an asteroid would be volatiles such as H2O. Then you have industrial metals, things like Iron, Nickel, and Platinum group metals. Going further, you can break apart many of the oxide minerals you would find to get oxygen (getting you closer to producing rocket fuel in-situ!). Its feasible, but still needs alot of testing both here on Earth and eventually needs to be tested on a target. It may be that governments, via agencies like ESA or NASA, may do it first, to prove the principles somewhat, but I know many commercial entities are also aggresively working towards space mining. To show you that its definitely possible, I'd like to plug the work of colleagues who have processed lunar regolith (which is similar to what you may find on asteroids) to extract both oxygen and metals. Check it out here: http://www.esa.int/ESA_Multimedia/Images/2019/10/Oxygen_and_metal_from_lunar_regolith

Will 2020's climax be a really big rock? DVK: Let's hope not...
Considering NASA, ESA, IAU etc. is working hard to track Earth-grazing asteroids, how come the Chelyabinsk object that airburst over Russia in 2013 came as a total surprise? The Chelyabinsk object came from the direction of the Sun, where unfortunately ground-based telescopes cannot look at. Therefore, it would not have been possible to discover it in advance with current telescopes. Dedicated space telescopes are needed to detect objects coming from this direction in advance.

the below is a reply to the above
Is this to say that it was within specific solid angles for the entire time that we could have observed it given its size and speed? Yes, precisely that. We got unlucky in this case.

Have any of you read Lucifer's Hammer by Larry Niven? In your opinion, how realistic is his depiction of an asteroid strike on Earth? DVK: I have – but really long ago, so I don’t remember the details. But I do remember that I really liked the book, and I remember I always wanted to have a Hot Fudge Sundae when reading it.
I was thinking about the asteroid threat as a teen and came up with this ideas (Hint: they are not equally serious, the level of craziness goes up real quick). Could you please comment on their feasibility? 1. Attaching a rocket engine to an asteroid to make it gradually change trajectory, do that long in advance and it will miss Earth by thousands of km 2. Transporting acid onto asteroid (which are mainly metal), attaching a dome-shaped reaction chamber to it, using heat and pressure to then carry out the chemical reaction to disintegrate asteroids 3. This one is even more terrible than a previous one and totally Dan Brown inspired — transporting antimatter on asteroid, impacting and causing annihilation. Thank you for this AMA and your time! DVK: Well the first one is not so crazy, I have seen it presented... the difficulty is that all asteroids are rotating in one way or another. So if you continuously fire the engine it would not really help. You'd need to switch the engine on and off. Very complex. And landing on an asteroid is challenging too. Just using the 'kinetic impactor' which we will test with DART/Hera (described elsewhere in this chat) is simpler. Another seriously proposed concept is to put a spacecraft next to an asteroid and use an ion engine (like we have on our Mercury mission BepiColombo) to 'push' the asteroid away.
As for 2 and 3 I think I will not live to see that happening ;-)
What is the process to determine the orbit of a newly discovered asteroid? The process is mathematically quite complex, but here's a short summary.
Everything starts with observations, in particular with measurements of the position of an asteroid in the sky, what we call "astrometry". Discovery telescopes extract this information from their discovery images, and make it available to everybody.
These datapoints are then used to calculate possible trajectories ("orbits") that pass through them. At first, with very few points, many orbits will be possible.
Using these orbits we can extrapolate where the asteroid will be located during the following nights, use a telescope to observe that part of the sky, and locate the object again.
From these new observations we can extract new "astrometry", add it to the orbit determination, and see that now only some of the possible orbits will be compatible with the new data. As a result, we now know the trajectory better than before, because a few of the possible orbits are not confirmed by the new data.
The cycle can then continue, with new predictions, new observations, and a more accurate determination of the object's orbit, until it can be determined with an extremely high level of accuracy.
MM
What are some asteroids that are on your "watchlist"? We have exactly that list on our web portal: http://neo.ssa.esa.int/risk-page
It's called "risk list", and it includes all known asteroids for which we cannot exclude a possible impact over the next century. It is updated every day to include newly discovered asteroids, and remove those that have been excluded as possible impactors thanks to new observations.
MM
the below is a reply to the above
That's quite a list!! Do you guys ever feel stressed or afraid when you have to add another dangerous candidate (and by dangerous I mean those above 200m) is added to this Risk List? Yes, when new dangerous ones are added it's important that we immediately do our best to gather more data on them, observing them with telescopes in order to get the information we need to improve our knowledge of their orbit.
And then the satisfaction of getting the data needed to remove one from the list is even greater!
MM
What inspired you to go into this field of study? I was fascinated by astronomy in general since I was a kid, but the actual "trigger" that sparked my interest in NEOs was a wonderful summer course on asteroids organized by a local amateur astronomers association. I immediately decided that I would do my best to turn this passion into my job, and I'm so happy to have been able to make that dream come true.
MM
this is another reply DVK: I started observing meteors when I was 14, just by going outside and looking at the night sky. Since then, small bodies in the solar system were always my passion.
As a layperson, I still think using nuclear weapons against asteroids is the coolest method despite better methods generally being available. Do you still consider the nuclear option the cool option, or has your expertise in the field combined with the real-life impracticalities made it into a laughable/silly/cliche option? DVK: We indeed still study the nuclear option. There are legal aspects though, the ‘outer space treaty’ forbids nuclear explosions in space. But for a large object or one we discover very late it could be useful. That’s why we have to focus on discovering all the objects out there as early as possible – then we have time enough to use more conventional deflection methods, like the kinetic impactor (the DART/Hera scenario).
It seems like doing this well would require international cooperation, particularly with Russia. Have you ever reached out to Russia in your work? Do you have a counterpart organization there that has a similar mission? DVK: Indeed international cooperation is important - asteroids don't know about our borders! We work with a Russian team to perform follow-up observations of recently discovered NEOs. Russia is also involved in the UN-endorsed working groups that we have, IAWN and SMPAG (explained in another answer).
how much can experts tell from a video of a fireball or meteor? Can you work out what it's made of and where it came from? https://www.reddit.com/space/comments/hdf3xe/footage_of_a_meteor_at_barrow_island_australia/?utm_source=share&utm_medium=web2x If multiple videos or pictures, taken from different locations, are available, then it's possible to reconstruct the trajectory, and extrapolate where the object came from.
Regarding the composition, it's a bit more difficult if nothing survives to the ground, but some information can be obtained indirectly from the fireball's color, or its fragmentation behavior. If a spectral analysis of the light can be made, it's then possible to infer the chemical composition in much greater detail.
MM
I've always wanted to know what the best meteorite buying site is and what their average price is?? DVK: Serious dealers will be registered with the 'International Meteorite Collectors Association (IMCA)' - https://www.imca.cc/. They should provide a 'certificate of authenticity' where it says that they are member there. If you are in doubt, you can contact the association and check. Normally there are rough prices for different meteorite types per gram. Rare meteorites will of course be much more expensive than more common ones. Check the IMCA web page to find a dealer close to you.
Just read through Aidans link to the basaltic rock being used as a printing material for lunar habitation. There is a company called Roxul that does stone woven insulation that may be able to shed some light on the research they have done to minimize their similarity to asbestos as potentially carcinogenic materials deemed safe for use in commercial and residential applications. As the interior surfaces will essentially be 3D printed lunar regolith what are the current plans to coat or dampen the affinity for the structure to essentially be death traps for respiratory illness? At least initially, many of these 3d printed regolith structures would not be facing into pressurised sections, but would rather be elements placed outside and around our pressure vessels. Such structures would be things like radiation shields, landing pads or roadways, etc. In the future, if we move towards forming hermetically sealed structures, then your point is a good one. Looking into terrestrial solutions to this problem would be a great start! - AC
What kind of career path does it take to work in the asteroid hunting field? It's probably different for each of us, but here's a short summary of my own path.
I became interested in asteroids, and near-Earth objects in particular, thanks to a wonderful summer course organized by a local amateur astronomers association. Amateur astronomers play a great role in introducing people, and young kids in particular, to these topics.
Then I took physics as my undergrad degree (in Italy), followed by a Ph.D. in astronomy in the US (Hawaii in particular, a great place for astronomers thanks to the exceptional telescopes hosted there).
After finishing the Ph.D. I started my current job at ESA's NEO Coordination Centre, which allowed me to realize my dream of working in this field.
MM
this is another reply DVK: Almost all of us have a Master's degree either in aerospace engineering, mathematics, physics/astronomy/planetary science, or computer science. Some of us - as MM - have a Ph.D. too. But that's not really a requirement. This is true for our team at ESA, but also for other teams in other countries.
What is the likelihood of an asteroid hitting the Earth In the next 200 years? It depends on the size, large ones are rare, while small ones are much more common. You can check this infographics to get the numbers for each size class: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
MM
Have you played the Earth Defence Force games and if you have, which one is your favourite? No I have not played the Earth Defence Force games, but I just looked it up and I think I would liked it. Which one would you recommend?
HG
How close is too close to earth? Space is a SUPER vast void so is 1,000,000 miles close, 10,000,000? And if an asteroid is big enough can it throw earth off its orbit? DVK: Too close for my taste is when we compute an impact probability > 0 for the object. That means the flyby distance is zero :-) Those are the objects on our risk page http://neo.ssa.esa.int/risk-page.
If an object can alter the orbit of another one, we would call it planet. So unless we have a rogue planet coming from another solar system (verrry unlikely) we are safe from that.
How can I join you when I'm older? DVK: Somebody was asking about our career paths... Study aerospace engineering or math or physics or computer science, get a Masters. Possibly a Ph.D. Then apply for my position when I retire. Check here for how to apply at ESA: https://www.esa.int/About_Us/Careers_at_ESA/Frequently_asked_questions2#HR1
How much is too much? DVK: 42 again
Are you aware of any asteroids that are theoretically within our reach, or will be within our reach at some point, that are carrying a large quantity of shungite? If you're not aware, shungite is like a 2 billion year old like, rock stone that protects against frequencies and unwanted frequencies that may be traveling in the air. I bought a whole bunch of the stuff. Put them around the la casa. Little pyramids, stuff like that. DVK: If I remember my geology properly, Shungite forms in water sedimental deposits. This requires liquid water, i.e. a larger planet. So I don't think there is a high chance to see that on asteroids.
