Has anyone else publicly copied the Hindenburg investigation/financial model? It's not proprietary AFAIK.
Despite it being a necessity for functioning markets, when you are short, seemingly everyone is against you - business management, regulators, media, etc.
Not surprised to see them bow out. Chanos did so last year.
This is one of the reasons frauds go on so much longer than you'd expect - no one wants to hear the truth.
Also, with shorting the best you can do is double your money (if the stock goes to 0), while you can lose an unlimited amount (as there’s no cap on a rising stock); whereas with going long, you can only lose all your money (again, if it goes to 0), but you can gain an unlimited amount.
Right now, Walmart is at $91.34, and you can buy a put at $88 expiring on 24th January for $0.18 [1]. If you buy one, and the stock goes to zero by then, you spent $0.18 and gained $88, a 488x return. January 2026 at $86.67 is $5.35 - a mere 16x return.

(This number is large because Walmart is not going to go bust in the next few days! It serves to illustrate the arithmetic, but maybe it's not the most realistic example.)
Premiums are usually small, so you can make many multiples of paid premium
And since their business model is releasing the findings, which in turn makes the stock drop, they can time their short position very well and don't need to pay premiums for long
According to Investopedia, "the Federal Reserve Board requires all short sale accounts to have 150% of the value of the short sale at the time the sale is initiated" so it's the same principle as going long with margin. You can leverage yourself but there's a limit.
But, of course, that gets ugly when the stock goes up; that's when you have to start putting your own money in against the borrow.
The price drops to $1 per share. You spend $10 to buy those shares and return your loan.
So you spent $10 and made $90. That's a 9x gain.
Yes you cannot make more than $100. But of course you can! Do the short on 1000 shares instead of 10.
The more confident you are of the share price going down, the more shares you borrow. Unlimited upside.
yep, people who aren't professional traders, and don't actually have an account with a broker to do shorting with, and dont know the margin requirements.
The thing is, a broker will _never_ put themselves at risk of losing money. If they offer you a shorting service, they require a method to make themselves whole. If you short, they will guess some sort of margin of safety for said short (calculated based on the liquidity of the stock) - if it's very liquid, the margin could be lower, but for illiquid stocks, it's even higher. This margin of safety is what the broker will use to close your short position if the market moves against you - you don't get a choice in the matter. You don't even have access to those funds from the sale of the short - the broker holds onto it until the short is closed.
Given the regulatory environment we are heading into, I expect short selling will become an even riskier business since the SEC isn't going to be prosecuting fraud anymore (or rather, they'll be doing even less than they are now), making it much easier to sic the lawyers on firms like Hindenburg. Even though this isn't their stated reason for bowing out, I wouldn't be surprised or hold it against them if it was a factor.
They highlight inflated sales and financial irregularities like a chain of companies that engage in self-dealing, but are portrayed as independent to hide their real ownership, and so on.
If you believe what they say, your faith in the company is shaken because they're pulling a con job on you to invest in them and believe their story. If the SEC investigates that just supports the claim that it's a con.
If they don't investigate - for whatever reason - it doesn't mean that it's not a con and you won't lose all of your money believing it.
So a change in the regulatory environment is only one element.
For example, the Modhi/Adani thing is outside the reach of the SEC. And after watching a piece on it, apparently shorting it was amazingly tricky, and they had to go through some Singaporean markets to arrange a short position.
... and the market can stay irrational longer than you can stay solvent.
I remember once I tried shorting a stock, of a market leader in my area. I knew the field well enough to see that they were trying to fudge some numbers and their quarter was _not_ as good as they had claimed it to be.
But sadly the market didn't see this and the stock went up. E*Trade started pushing me to cover my positions, and eventually I ended up losing a 5-figure sum (nothing earth-shattering, but still a good chunk of my cash).
After I had bought it all back, slowly the market realized what I had seen and the stock dropped as I had expected. Unfortunately I did not have the deep pockets to stick around long enough; all I was left with was a hole in the wallet and a hard lesson learned.
The SEC has a policy of paying out part of recovered fines as bounties to whistleblowers to align incentives. If your company is doing something sketchy, you get a payout by doing the right thing.
I’m not a lawyer but I think that mechanism works just as well if you’re an external reporter of fraud. SEC makes money and pays you for your diligent forensic auditing.
Astute observers and outsiders - doing the same thing prolific short sellers do - have received some of the biggest bounty payouts
The source is on the SEC’s bounty payout page
where did you get 1% from, its a really good bounty system to clean up the markets and you get to be anonymous if you use a lawyer, the trick is to get the SEC to prioritize it. They are now inundated after some large payouts made the news in financial circles
On its surface, nothing crazy for long/short funds, the notable part was that basically all the effort was on the short side, and the long side was implied to be very humdrum. And the short book had like negative returns over a long period. It just struck me as a really elegant (if extreme) example of what uncorrelated returns can do if you do somehow have some edge over time.
And I'm not sure what Hindenburg's holistic picture is, but whether rightly or wrongly now I usually assume most of the kind of very public shorts operate similarly. I was never really on board with the "short sellers are evil" train of thought, but I did believe, "oh these very public short sellers only short things, they just go around all the time thinking everything is awful". And my assumption now is that they are like, kind of really theatric long/short funds.
Matt had some line like if you extremely good at something, you can get rich doing it, even if it loses money. As long as it's not correlated.
> Beyond my own desire for relief, it also feels selfish to keep the knowledge we’ve accumulated trapped within our small team. I have more than enough. In the past several years we’ve been flooded with thousands of messages from many of you asking how we do what we do, or whether you can join the team. I read them all and I’ve been trying to figure out how to respond in a way that can answer everyone—so over the next 6 months or so I plan to work on a series of materials and videos to open-source every aspect of our model and how we conduct our investigations.
Just because some company is accused shenanigans or breaking the law doesn't mean they won't try to litigate you out of existence.
Or that they don't have associates with baseball bats who might visit you in the night to discuss your "bad choices".
It takes some real minerals.
I have read somewhere (long ago forgot where) that the only country this can work is America; in other countries, he would need to be scared for his actual life. Adani, for example, is in bed with India government.
