Insider trading by executives is pervasive – research

> Of the 496 trades [Filler has] made since 2014 in Alabama’s ServisFirst Bancshares Inc., where he sits on the board of directors, and Century Bancorp Inc. of Massachusetts, where he’s the largest shareholder, 372 of them, or 75%, have shown a profit three months later.
> Besides Filler, other TipRanks stars include Steve Mihaylo, the CEO of telephone services company Crexendo Inc., where he owns a $60 million stake. Mihaylo has turned a three-month profit on 83% of his trades over the past five years even as Crexendo’s shares have seesawed.
We've also had an unprecedented bull market over the past 10 years. If you pick any random stock at any time and hold it for three months, what are the odds that it will be worth more?
The article compares the returns to the S&P500, but that is the net performance of those 500 stocks. You'd have to compare it to the base rate of picking a random stock to see if it's actually remarkable.
Maybe the S&P 500 performed lower because 75% of the stocks in it went up and 25% went down. But that means that if you randomly pick one stock, you'd have a 75% chance of it being one of the ones that went up, and you'd outperform the S&P500. (Well, not quite, maybe it could go up, but not as much as the S&P500 as a whole. But still, most of the stocks that go up, would have to go up more than the average of the whole index in order to compensate for the ones that go down)
Later in the article, when they mention that insiders tend to reliably sell stock ahead of bad news, that seems much more damning.
The real issue is people wouldn’t bring it up if the number wasn’t “shocking”. Which self selects for outliers.
I just hate hearing these same narratives being repeated because... they've already been repeated. Why must stock returns be random? It's predicting whether a company is going to do well or not, which has nothing to do with randomness. And yet people (like this commenter) just keep repeating this stuff, absolutely endlessly. They don't even know why they're doing it (try asking him) -- they just keep doing it.
You're right that that has little to do with randomness. But it also has little to do with investing.
Random paper (Fama et al.) doesn't say it's impossible to predict how well a company performs. It says why do you think you can predict better than the 1000 Ph.D. employed by trading co. inc. when all of you have access to the same public information? So the price of the company's stock is going to converge to some number that already reflects the known information.
Not sure where you're getting the stock returns are random bit either.
If you read hn a lot and built a lot over the past decade it hasn’t been hard to predict better than “a 1000 phds” which companies would win.
NVIDIA, apple, even small plays like twilio. It was obvious these companies had big leads in stuff that made money.
Go back and read the Cloudflare IPO filing thread here. That opened at what, $16?
You read the R2 thread from a few days ago it is again obvious AWS will bleed some of the most influential engineers when this becomes generally available. I don’t have a PhD mind you, but I would presume this will lead to entire companies moving to CF for some primitives, eventually CF pick up entire accounts.
Do PhDs at trading companies get annoyed because some AWS services still will only respond with plain/text in api responses containing json? That they have to write a custom parser as a result?
Or that the UI for AWS SNS in setting up an HTTPS subscriber kinda sucks? Like it was mostly done but worked so people got pulled elsewhere?
Do wall street PhDs realize the bundling of expensive AWS cloud primitives to use other AWS cloud products is anti-customer, and that maybe this is going to translate to devs voting with their feet when CF makes this move?
Heck, even the R2 announcement makes the egress fees issue clear in plain English. There are tons of comments validating that pain. Business people shouldn’t need a lot of convincing.
Do the above observations and experiences working with AWS and reading others experiences add up to more knowledge than 1000 PhDs?
I wouldn’t have thought so, but the value of an academic degree has been on a downward spiral for some time.
Is it obvious? How likely is it that you're right - is the chance 100%? Is it even possible that you're wrong and this don't happen?
Besides, successful trading is more about getting the timing right than it is about picking which companies will eventually increase in value.
well one reason would be that there is something about the market at time X that means conventional wisdom is faulty, since the 1000 Ph.D. employed by trading co. inc will be following the conventional wisdom there is a chance to outwit - years leading up to 2007 housing crash spring to mind as an example where this can happen.
Sure, if you’re correct it’s easy to say the logic was sound, but you never learn the odds just what happened.
That market has a lot of very smart people spending a lot of time making their predictions. If you can consistently identify stocks that are undervalued then either you are smarter than the rest of the market, or you know something the rest of the market doesn't.
It is possible to be smarter than the rest of the market. Particularly if you are investing in relatively low value companies and doing significant due diligence yourself. However, if you work in Congress, it is much more likely that you got your edge by knowing something that the rest of the market doesn't, and we have generally decided that it is illegal to make trades based on that information.
This can't happen because prices rise as a consequence of buying and fall as a consequence of selling. People who bet on a pattern destroy it.
The consequent randomness is easily verifiable. Try running some stock market data through a machine learning library, you won't get any interesting results.
This data has been around for years
But if the market has been going up, even underperforming it means you can still make a profit (unless you significantly underperform). The quoted text in the gp is just talking about profit, not comparing to the market.
If the price movement was completely random with no bias up or down, and you entered trades at completely random times, then you would expect 50% of trades to be profitable 3 months later. So 50% is our baseline. Then consider that these stocks have been going up. THEN consider that you don't have to enter trades at completely random times; if you buy during a dip, the price merely needs to return to the mean for you to be up.
> If you pick any random stock at any time and hold it for three months, what are the odds that it will be worth more?
High, very high if you filter down to the most likely stocks that would be traded, apple etc.
That is surprisingly close to the number Matt Levine reported on some time ago. A group was trading almost exclusively on insider information, and (IIRC) 77% of their trades made a profit. It's a massive edge over other market participants, but only goes to show that even with that kind of information at your disposal, you are still not guaranteed to make money on every trade.
I wish I could find the article. The overlap between "Matt Levine article" and "insider trading" sets is large enough to make any search for a particular piece of news a needle/haystack problem.
EDIT: to clarify - when you are trading on inside information with the goal of making a quick buck, you are not interested in how the company will do in short term. You are trying to predict how the market in aggregate will react to that same information, once it becomes public.

There are regulations but no enforcement except for smaller players within the financial industry.
But you’re right there are more clearly corrupt officials including two fed presidents. This is a systemic problem of poor enforcement and violated norms. The rule of law matters and regulators should be above reproach.
The fed's policies affect every area of the financial system. Can't put it in a bank because they'll almost certainly be above the insured amount and will have an incentive to bail out that bank if it's in trouble, another conflict of interest.
Perhaps some special account at the fed that pays a specific interest rate and is fully insured? But then why do Fed presidents get special access to such an account that normal folks don't?
I don't know that there is anywhere he could put his money and be above reproach, him putting his money in muni's seems like a good faith effort to do that though.
Because otherwise it's easy to just cynically say he's lining his own pockets when in practice the position inherently makes it impossible to have zero conflicts of interest.
Anything would be better than buying the very assets they are meant to oversee.
You’re defending the indefensible here with sophistry about how hard it is to be honest and avoid double dealing. These fed presidents dealt in the very securities they had inside information on.
Traders in financial institutions can invest in assets outside their job and likely those traders don't have the financial muscle to move the values of entire sectors the way the fed can.
Again, there is nowhere existing at present that a Fed chairman can invest that is outside his/her influence, nowhere there is no conflict of interest in the current financial system.
The only real solution is some kind of defined fed official only fund as you and I have both suggested. But while this would get rid of conflict of interest it enters into an issue of equality of why should fed officials get guaranteed safe investments when the public at large do not, which is why it's probably never been done.
An even simpler solution would be to hire someone for this position _who lived off their salary._
The idea that these positions always have to be given to fabulously rich people is why America is in the crappy position it is now.
If they didn't make a lot of money, they probably never rose to positions that gave them the experience they need to do the job?
When they might as well be criminals. Look at the Pandora leaks
It ended[2] up with him transferring his personal assets to a bank account and the ownership of the hedge fund to a charity foundation he had started long before this.

That seems like a solution. And yes, some leadership positions require you to restrict your private activities outside the job.
Before Trump, it also used to be common courtesy that the president-elect published his tax returns and removed himself from all projects that could lead to a conflict of interest.
I was 100% out after 2008 (I saw it coming; I saw the Dot Com crash coming - I finally realized the entire system is utterly corrupt and only "the house" wins - you are NOT the house.
Simply invest in a total market fund and you get the average returns of the market. Even investing in 1999 or 2007 in a total market fund would put you ahead of a savings account by now.
What do I mean? Mark Cuban sold a collar on his Yahoo stock through Goldman for $[I forget] billion dollars. That was an off-market trade in which someone bought his entire block off of him. In today’s world, with tons of low interest (as in, single/double-digit basis points) loans and other fun weird contraptions, you have a lot more options to trade without trading.
I have no grand reveal here, but there’s probably an entire “dark dataset” regarding that activity that is missing from this conversation.
And so, according to how I was told, the accountant, after dropping off the document and walking out of the SEC building, would pull out his cell phone and call his buddy from the front steps with the relevant info. The buddy would then make trades on the now-"public" info that no one else yet knew, because it was still on a piece of paper in the SEC office that no one had yet looked at.
Could it really have been that easy? This would have been the 1980s or so, I think. I think they had cell phones then, but if not, they had pay phones.
The speed of communication outpaces the speed of government bureaucracy so it’s easy to take advantage of a technicality to make huge profits.
It’s like university exams when a friend in a morning class would take an exam and then tell others in the afternoon class about the questions and what to expect before taking the exam. The no guarantee the exams would be the say, but even if some questions overlap it makes a big difference.
In the case of university, I’m pretty sure this would be some kind of honor policy violation with repercussions if found out, and for Wall St it’s probably not even as tough as uni.
Maybe a market that didn't pretend insider trading didn't happen would look somewhat different.
I can witness the same structure at my job. We all see stuff (not financial related) the public is not aware of. It would be easy to take advantage of that.
This is both theoretically and practically impossible.
Many things: Records of communications. People talk.
Ladies and gentlemen of the jury: the defendant changed his 10b5-1 plan multiple times, and one of those times he profited hugely from it. The defendant's excuse that his advisor told him to do it and he needed the money for his daughter's college is just unpersuasive.
Anyone see why a prosecutor might be reluctant to bring such a case? It might well be true, but the jury may or may not stay awake long enough to agree. Best to concentrate scarce resources on cases you CAN win.
Note that I'm not saying insider trading is harmless; just that it's like illegal drugs: no policies will stamp it out entirely.

Not only is it insider trading, it's clear that the briefing indicated the amount of suffering that was coming to their constituents.
In any case, this is distasteful and gross. Every bill should have an estimated impact on publicly traded companies, and politicians with stocks should be forbidden to discuss/mediate the bill, and only vote on it.

I don't think this is feasible.
> and politicians with stocks should be forbidden to discuss/mediate the bill, and only vote on it.
But I'll go one further on this. No person holding public office above a certain level should be allowed to trade individual stocks. Either buy broad-market indices or have a third-party invest for you without your knowledge on specifics.
These people should not be allowed to hold any kind of private or public stock other than ETFs of the S&P 500 index. This way you remove the conflict of interest in favoring one sector/company over another and instead if they want to make money through the market they can do so by helping the overall economy instead.

(It would also be infeasible to mandate the divestiture of small, closely-held family businesses in order to hold office.)
He eventually sold it but only after leaving the Presidency (in large part because it was then under crushing debt, having been run by “not the people who knew and cared about the business”.)
I’d rather have us have politicians who are “like us” (who might have an LLC with a rental property in it, who own a pizza shop/dry cleaner/corner bodega, a consulting shop, etc.) than to restrict politics only to those with nothing to lose or so much to lose that if they lose some in a quest for power, it’s OK. I don’t want to shut small businesspeople out because they’ll lose everything they’ve worked to build.
We need people in government who know what it’s like to have to work to make payroll and to sign paychecks on the front.
Dehumanizing, isn't it? Working hard to contribute to society while these people accumulate 10, 100, 1000 times our yearly salaries in seconds by playing some market. The world we live in is so absurd, it's such a joke.

So yeah, hearing "there's a law against this but there's no enforcement of that law"...most people shrug and say, "ok, that's legal".
In additon there are thousands of elected officials across the country. If we need everyone to abandon/destroy their non-official form of income, nobody will join politics. It is easy to judge from that sidelines.
It was already known in 1987 that he traded while spreading false information and after a couple of years the entire stock market ignored him.
They were really years ahead of everyone else on what to do.
Of course, or some other mechanism.
> In additon there are thousands of elected officials across the country. If we need everyone to abandon/destroy their non-official form of income, nobody will join politics. It is easy to judge from that sidelines.
So you are saying that politics is inherently corrupt and that if you take away the appeal of corruption then no one will participate?
I've heard rumors that quite a bit before I was born, politics was as boring and stuffy as being an actuary. One can only dream that politics gets boring like that soon.
Absolutely, 100% agree. We should also not let children of Presidents get entangled in billion dollar investment deals with foreign powers that are hostile to US interests[1]
There are blind trusts and other vehicles that can be used. Maybe if the ability to exploit inside knowledge for personal financial gain were limited, the people who choose to get involved in politics would be doing so because they care about making the country a better place, and not to enrich themselves.

Professionals deal responsibly with conflicts of interest all the time. If you mishandle them, that's somewhere between bad judgement and a punishable offense.
Is there a way to "index-fund" Pelosi's investments? More generally, "index-funding" the investments made by politicians who are in a position of power would be a really interesting thing.

I would be more concerned with presidents who are known to spread/say things to try to influence the market.
Such a system seems possibly fairer and more efficient than what we have now.
What is needed is instantaneous reporting.
Yes, because democratic institutions have such a great track record of managing things like this
Nation states and institutions can build on top of or integrate into this base network rather than building their own walled gardens. Long term this improves auditability and protects these institutions' CBDC networks from censorship.
How do you think we got that miraculous bounce post-Covid?
The Federal Reserve had to step in with ~$8 trillion and start buying stocks.
Two Fed presidents had to step down recently due to their stock holdings.
They had to do this to save everyone's retirement accounts and the housing market.
And now we have inflation and this will get blamed on the President's policies. It has nothing to do with that, it's this massive injection of cash into the system. They may have gone a little overboard.
They are trying to slowly unwind this. Until then it's "party like it's the 1920s".

How about: make all trades 100% transparent in real time, and nevermind the insider trading laws? If Jack Smith, the CFO of XYZ Corp, sells 300 shares at 11:04:00 AM, you can know about it by 11:04:01. Sure, Jack still has an advantage, but now his trade is ACTUALLY providing information to the market.
It is one thing for TipRanks to provide analysis two days after, another thing for them to be able to do it in almost real-time, or setup a Fast Follower fund...
Seems there's only good to be gained here, and the insiders won't have to worry about prosecution.
If society keeps seeing investing as an absolutely necessary thing for financial stability, we can't expect politicians and executives to not be corrupted.

Go enjoy your American dream, the rich people that is.
His point, which is pretty much impossible to argue with, is that insiders always have material nonpublic information about the companies they work for, so treating “insider trading” as a categorical evil that must be totally eliminated is just denying reality. You would have to bar insiders from ever trading their own stock under any circumstances, which seems silly.
The alternative view is basically “who cares”, and that barring insiders from trading freely actually impedes efficient price discovery. A compromise might be to require insiders to at least publicly disclose all trades, so that markets know when insiders are making moves.
Why is it silly? It seems perfectly reasonable to me. There are 10's of thousands of other stocks to trade.
This feels like you're begging the question, or that you left off a step or two at the end and stopped a bit short of a complete argument. Maybe something about equity compensation being a valuable tool that can provide a beneficial incentive structure that is not easily achieved through other means?
Unless they pass a law that monitors every single transaction of every person of interest, and even then, I'm sure my RIA would love to know if I had a juicy tidbit and could trivially hide it, I just don't see how you ever stop it.
That world isn't made for the people on HN.
Fine? That's my point. Can't be done. Like trying to forbid certain strata of civil servants from using encrypted communications.
I get that connected insiders need more scrutiny and maybe making some high profile examples would set the tone, but that some bad actors don't bring the whole thing down is more of a feature than a bug in this case.
The market being rigged (in the casual sense used here) does not require anyone to be manipulating all of the factors that affect prices; you just need to be able to cheat on some input to the system. Trading on non-public information may not always be a successful strategy because you might get unlucky and some other factors could unpredictably outweigh the impact of the insider information you're basing your trades on—but on average, insider trading works until/unless you are caught and prosecuted.
This leaves out some key facts: different people have access to information at different times.
It isn't fair (and it isn't good for market efficiency) for insiders to act on their inside information. This isn't disputed.
I think we accept the increased inefficiency (from barring insider trading) in the name of fairness and resulting trust in the market.
Laffont, Jean-Jacques, and Eric S. Maskin. "The efficient market hypothesis and insider trading on the stock market." Journal of Political Economy 98.1 (1990): 70-93.
How is this not good for market efficiency? Insiders have material information about company performance. Trading on that information means that it is (marginally) reflected in the market price. That sounds like a more efficient market to me.
Also, I’d like to see your full specification of “fairness” in capital markets. Stock markets are not casinos, they are economic tools for directing capital to its highest use. “Fairness” doesn’t seem like a relevant factor here.
Some sources to consider include:
1. From Brittanica' ProCon.org: https://insidertrading.procon.org/view.answers.php?questionI...
2. Finnerty, Joseph E. "Insiders and market efficiency." The journal of finance 31.4 (1976): 1141-1148.
From the latter:
> THE STRONG-FORM of the efficient market hypothesis assumes all available public and private information is fully [reflected] in a security's market price. The strong-form, in terms of market participants, also assumes that no individual can have higher expected trading profits than others because of monopolistic access to information. One possible test of the strong-form is to determine whether insiders earn better than average profits from their market transactions. To ascertain if the market is truly efficient will involve determining how well insiders do relative to the market in general. To date, some work has already been done in evaluating rates of return earned by insiders trading for their own accounts. ...
I would wager (in a prediction market) that many people who cite the efficient market hypothesis may be unaware of the second sentence in the quote above.
