The idea for this guideline is not to link to a teaser that can't be used. You can use this. You just need to sign in.
Most likely, clicking and encountering nothing but a login form is the reason why people started flagging the submission. When users see a page like that, they pattern-match it to a different kind of submission—a boring corporate promotion designed to collect signups. (We get a lot of those.) Keep in mind that many readers will have clicked before looking at the comments.
In its simplest form, insider trading consists of someone knowing something about performance or similar relative measures that would affect a stock price. But as Matt Levine points out, knowing the future isn't that helpful [1]. Research found that even when it has been proven that professional investors had and acted on insider information, their track record was still spotty.
I even made an app [2] where you can get a companies past and future performance numbers, and you try and guess which of two opposite paths the stock took. I call it the insider trading game, and its a lot harder than it looks.
[edit] Just reminded of the Jim Cramer still showing two headlines: "More than 16M Americans have lost jobs in 3 week, dow's best week since 1938" [3]. I'm skeptical a non-professional trader would be able to somehow deduce strong stock market performance from early access to something like 16mm Americans having lost their jobs in 3 weeks.

The range is from 1993-1998 while this was published in 2004. I'm not sure why that range was selected.
Also, consider the universe:
> Initially, we begin with 6,052 transactions. Before analysis we apply several screens to the data. Only U.S. common stocks are included in the study. These screens eliminate, among other things, all preferred stock, ADRs, REITs, foreign stocks, and mutual funds. We also eliminate all initial public offerings (IPOs) from the sample.2 In total, 360 observations are eliminated for the reasons given above. Among the surviving transactions, approximately 59% of the stocks are listed on the NYSE, 40% are traded on the NASDAQ, and about 1% are listed on the ASE.
Why eliminate those other things? Would the conclusion have changed if they had been included?
> As indicated previously, Senators report transaction amounts only within broad ranges.
Ranges are as follows:
$1,001 to $15,000
$15,001 to $50,000
$50,001 to $100,000
$100,001 to $250,000
$250,001 to $500,000
$500,001 to $1,000,000
over $1,000,000
And from the paper:
> As before, we again estimate the value of their trades using the midpoint of the range reported by the Senators for all transactions less than $250,000. For all transactions above $250,000, we assume a transaction size equal to $250,000.
Why floor it at 250? Why not keep the midpoint, at least for 250 - 500 and 500 - 1mm?
I also thought it was odd to look at two portfolios, one of buys and one of sells. If the buys outperformed, but sells were a lot larger, then its not a good strategy on the whole. That's before we even get to the performance measure used.
Think could all be above the board and decided upon prior to actually crunching the numbers. But there are too many things here for me to definitively buy the narrative.
Really enjoyed your medium series btw!
On another note, I was wondering how you got the data. So I opened my Chrome dev tools to see. I'll be checking financialmodelingprep.com out!

Elite wealth managers alone, btw. A minority of rich actually have marketable skills.
Has nothing to do with business acumen (math models have shown one time success was luck not skill and continued success is simply bought; hi Bloomberg)
So yeah let’s keep playing this game, guys! Physics I’m sure shows somewhere this was predetermined by the motion of the stars and matter we can’t see.
Why NOT subject the mathematical majority to a system that (conveniently) won’t educate them well enough to even offer a chance at falsifying the underlying presumptions!
From your blog: “Here’s a trade from David Perdue, the great Senator of Georgia. He actually made nearly half the trades of our dataset, and it makes sense since he’s worth $15.8 million”
Why would it makes sense for him to make half the trades because he is worth $15.8 million? Plenty of Senators are worth more than that.
On a unrelated note, how the hell can a senator sit on so much and be worth so much? Aren't they supposed to have the public in their main interest? Sitting on all those assets looks really suspicious. Seems they care more about themselves than their community/country.
$16 million is a not-unreasonable amount to save for a comfortable retirement that includes travel around the world and making sure your children get a good start to life, and says absolutely nothing about how much the person donates to society’s betterment.
The general advice is to have at least, what, a million saved for retirement. 15 is a lot, not so much that it’s unreasonable to my mind for a successful person.
I agree with you. But maybe if that's what you're aiming for, you should not be in decision power over the entire country. If you're seeking out that position, it should be because you want to see the entire country as your children. Those are the people we want as leaders.
Not the selfish hoarders that currently hold the power in most countries today.
They don't make more products or hire more people when someone buys a stock on the open market.
if he donates to charity - or as the POTUS does, gives his salary away (or doesn't) - that's entirely on him.
Being "rich" and "caring" are two separate and unrelated things...
If I care, but do something that makes more than I spend - or invest wisely into something that makes more... I care and make money...
"if you have money you don't care" is a seriously flawed attitude.
You're a public servant, supposedly working for the public, why you need so much? Share it with the ones who have zero instead. The US have a huge problems in many areas, like healthcare, homelessness and other serious problems, if these hoarders would actually display a bit of care towards those people, you can solve it.
But again, sitting on $15.8 million does not look like you're actually trying to solve anything else but your ego.
Why is your decision that "$1m is enough for anyone" (or whatever your arbitrary amount is) the correct one? Why not 100k? or 10m? (arbitrary numbers I know you haven't stated as such)
"You're a public servant" What does his personal finances have to do with his public service?
as long as he's not making his money from his service (IE: Kick backs, sweet deals for family, etc)?
Nothing.
"The US has huge problems" everyone/every country has huge problems in all these areas - each in different flavors. You could take 100% of money (or value, since a lot of "value" is in intangible stuff like property or stock that isn't "money") from everyone above $1m (or your arbitrary cutt-off) and guess what? We still couldn't afford "heatlhcare for all" and people will still be homeless. Money isn't the problem and it doesn't solve all problems. Just look at places like CA that are spending more and more and having worse and worst problems - the issue isn't money.
At the end of the day... his having 15k, 15m, 15b or 15t means nothing about his attitude, ego or ability to care.
Did you actually read the article? It specifically talks about press releases put out by companies. That’s just a sliver of the type of insider trading knowledge you can trade off of.
There are all types of other insider info. For example if you work at the FDA and know in advance what drugs are about to be approved/rejected.
Also I tried your app and the prompt it gives is... not even close to insider info
“ Regeneron Pharmaceuticals Inc is an integrated biopharmaceutical company. It discovers, invents, develops, manufactures, and commercializes medicines for the treatment of serious medical conditions.”
I fail to see how this is helpful info? Now if on the other hand it said “the company discovered a COVID drug in final approval with FDA”, that would be much easier to trade on.
Knowing the right future information can be insanely profitable. No matter what clickbait headline Matt Levine can come up with.
This is a verbatim example of not assuming good faith in the guidelines for this site
How is this relevant? Surely any senator knowingly engaging in insider trading wouldn't do so directly. They would get someone else to profit from the info and give back to them in either untraceable or legit ways.
However, in the Bloomberg article you mentioned, it was cited that the hackers had a 77% success rate. Any serious investor would tell you that's an incredibly high success rate, as it's impossible to be 100% right all the time. If you had that hit rate, you're almost guaranteed to beat the index by a very large margin.
Lastly, it's possible to still have insider info, and not make money on the trade. That doesn't make it legal, though, does it? I think that's still insider trading - it's just making the wrong bet. If I had access to all insider info, I'd be super picky. Ignore 99% of what I hear (ie 16M Americans are unemployed, big whoop! everyone knows), and only trade on the 1% of info that will almost certainly move the markets (ie COVID-19 will shutdown entire cities). Extremely difficult to do if you love trading, but the optimal strategy.

KID TRADERS
Using data on a half a million accounts from Finland from
1995 to 2010, the study came to a surprising conclusion:
accounts set up to benefit kids 10 years and under did
really well at stock picking, and did especially well just
before mergers, earnings releases and events that generate
big stock moves.
The analysis was possible since Finland makes available
unusually detailed information about the identities of
investors.
“When guardians trade through under-aged accounts, there
is a relatively high probability that they are trading on
private information,” the authors, Henk Berkman, at
University of Auckland, Paul Koch at the University of
Kansas and Joakim Westerholm at the University of Sydney,
conclude in a paper slated to be published in the Journal
of Finance.
The gap between the junior set and typical accounts held
by adults was striking: in the day following trades made
by kids, their accounts outperformed the adult accounts by
9 basis points.
Ahead of major earnings announcements, the kids chose
correctly whether to buy or sell 57 percent of the time
and beat their elders by 1.1 percent in the following day.
It gets even better - at least for junior. On trades made
the day ahead of a merger announcement, juvenile
portfolios outperformed by 12 percent the following day,
and made the right decision to buy or sell an uncanny 72
percent of the time.
The rest of the market, by the way, chose correctly
whether to buy or sell only 50 percent of the time.
This is probably not all due to inside knowledge,
according to the study. The guardians tended to be richer
and may simply have been more successful at investing, the
authors argue, due perhaps to higher intelligence or an
advantage in obtaining legal, but valuable information.
Even so, the fact that the juvenile accounts outperformed
ahead of mergers while the guardians’ accounts did not
implies that the adults were smart enough to know better
than to trade on inside knowledge in an easily traceable
way.Some feedback:
- INSIDER CONFIDENCE INDEX is missing some sort of description, not sure if it's actually Insider Sentiment Index which is a establish term or if it's something else.
- Increase the contrast as almost all of the text (except table headers text) is hard to read without really focusing.
The contrast is less about the fonts and more about the colors. Just making the darker a bit more darker and the light a bit lighter should solve the problem.

Yeah, this is a big reason smart people do not go into politics; the armchair-expert mob.
Do you have any sources where these self-proclaimed smart people tell us about their reasons for not going into politics? Many of the mainstream-smart people seem more interested in getting as much money for themselves than working for the public good.
Lite Pete did.
Or, play the Trump card and attack anyone who gets ybder the kimono too mych.

You can see who, when, which quantity, dollar amounts, dates... I signed up with your system and you only show in the LAST 6 MONTHS -- why not last century? Your title is a complete click and bait.
Anyone else seeing the same?
edit: OK I see others are experiencing the same thing.

Sounds like the founders might need a basic course in stats, before giving stock tips.
