What happened
Hertz closed at $1.51 on August 4, its lowest price in a year.
Six sessions later it touched $2.86, an 89% gain, on volume that reached 227 million shares in a single day against a 20.9 million average. Then on August 13 it gave back 16%.
Two numbers are being quoted everywhere about this stock right now: 89% off the low, and 59% of the float sold short.
The first is accurate. The second is accurate and badly misleading, and the reason why is the most useful thing in this article.
The June deal that set the whole thing up
On June 23 Hertz closed at $5.06. On June 24 it closed at $3.00, a 41% fall in one session, and the filings that day explain it.
The company announced two things at once:
$350,000,000 of 6.75% Exchangeable Senior First-Lien Secured PIK Notes due 2030, with an option for a further $50 million. First-lien means they rank ahead of essentially everything else. Exchangeable means they can turn into stock.
And, in the same breath, this:
We are offering 37,037,037 shares of common stock, which we will lend to J.P. Morgan Securities LLC... The share borrower, or its affiliates, will receive all of the proceeds from the sale of the borrowed shares.
Read that carefully, because it is unusual and it is the key to everything that followed. Hertz did not sell those 37 million shares for its own account. It lent them to a bank. The company received no proceeds from them.
Why that matters, and why "59% short" is not what it looks like
A share lending agreement exists for one reason: to let the buyers of the notes short the stock as a hedge.
This is standard practice, and it is called convertible arbitrage. A fund buys the exchangeable notes and shorts the shares against them. It is not betting the company fails. It is neutralising the share-price risk so it can earn the 6.75% and the option value.
Now look at the short interest with that in mind:
103,219,503 shares are short, against an implied float of about 175 million. That is 59%, and it is the number every screener is flashing.
But 37,037,037 of those borrowable shares were created specifically so the note buyers could short them. That is 21% of the float, delivered to a bank as part of a financing, and it is not a directional position at all.
### The distinction that decides how you read this
A directional short is betting the price falls. Good news hurts, and they cover, which is what a squeeze is made of.
A convertible hedge is indifferent to direction. It adjusts continuously and it does not panic. On a rally it may even short MORE, because the delta on its notes rises.
A large share of the 59% is the second kind. That does not make the number fake, and there are certainly real bears in there too. It means the squeeze fuel is meaningfully smaller than the headline implies, and anyone buying purely on "59% short" has not read the June prospectus.
The other consequence: shorts rose into the fall, from 97,539,992 on July 15 to 103,219,503 on July 31. Some of that is bears pressing. Some is simply the hedge being established as the notes settled on June 29. The data does not separate them, and neither should we pretend to.
Then earnings actually delivered
On August 6, Hertz reported second-quarter results, and the operating numbers were the best in years.
- Revenue $2.4 billion, up 10%, on a fleet that was 1% smaller. Growth from pricing, not from buying more cars.
- Strongest second-quarter revenue per day on record, excluding the 2022 market anomaly.
- Revenue per unit up 8%, revenue per day up 9%.
- GAAP net income of $64 million, diluted EPS $0.05.
- Adjusted Corporate EBITDA of $81 million, a $63 million improvement year over year.
- Total utilisation 81% excluding elevated recalls, up 190 basis points.
- Net depreciation per unit per month $302, in line with guidance, with about 94% of the U.S. core fleet on 2025 and 2026 model years.
- Liquidity $984 million.
The honest caveat, which the company disclosed and most coverage will skip: GAAP net income was $64 million, but the adjusted result was a $47 million loss, or $(0.11) per share. Those measure different things and both are true. The adjusted figure strips out items management considers non-operating; the GAAP figure includes them.
If you want one number for whether the business is genuinely improving, use the $63 million EBITDA improvement on a smaller fleet. That is hard to manufacture.
156 million shares on the print, then 227 million. Seven and eleven times normal. That is not a quiet re-rating.
Who owns it
Knighthead Capital Management and Certares, through CK Amarillo LP, hold 181,455,469 shares, 50.9% of the company. They have been the controlling holders since the post-bankruptcy restructuring.
Their August 10 filing is worth understanding correctly: it was Amendment No. 10, filed because the percentage moved, not because they bought or sold. The share count went from 315,764,523 on April 30 to 356,451,393 on July 30, mostly through the lending facility, so the same holding became a different percentage.
The practical effect for a trader is the float. Half the company does not trade. That is why a $838 million company can carry a 103 million share short position, and why the moves are as violent as they are in both directions.
Why this one draws a crowd
Hertz is not a random small cap, and the retail interest in it is not random either.
It filed for Chapter 11 in May 2020 and emerged in June 2021 with shareholders paid, which almost never happens in a bankruptcy and is the reason the ticker has lived on watchlists ever since. It was one of the original meme-era names. That memory is doing real work in how this move is being discussed.
Layer the current mechanics on top and you get the exact profile a screener surfaces: a sub-$3 price, half the shares locked up, 59% of the float short, six days to cover. If you were designing a stock to attract squeeze hunters, it would look like this.
Most of what the crowd is saying is factually correct:
- The float genuinely is tight, because 50.9% is held by two firms that are not selling into a rally.
- The short interest genuinely is large, and it genuinely did rise into the decline.
- Volume genuinely did go to eleven times normal.
- And unlike most squeeze candidates, the business genuinely did improve. That part is unusual and it is why this deserves more than a dismissal.
The single thing missing from almost every version of the story is the June share lending agreement, which is the difference between "103 million trapped bears" and "a large hedge book plus some bears."
There is also a tape-level check available, and it is worth more than any argument:
August 13. The stock fell 16.3% on 116.8 million shares.
A genuinely trapped short base does not sit still through a 16% down day on heavy volume. It buys, because that is the day the pressure comes off. What the tape showed instead was supply.
That is not proof of anything on its own. It is, however, the opposite of what a squeeze in progress looks like, and it happened on the most recent session available.
What moves it from here
1. Whether the operating improvement continues. The $63 million EBITDA swing on a smaller fleet is the real signal. One quarter is a data point; two is a trend. Next print is the test.
2. The exchangeable notes. $350 million at 6.75%, first-lien, and PIK, meaning the balance can compound rather than being paid in cash. That is expensive money and it sits ahead of shareholders. Watch whether interest is paid in cash or in more notes, because the second answer tells you about liquidity.
3. The short position, but read properly. If real directional shorts cover, moves get violent. But do not model the whole 103 million as squeeze fuel when 37 million of the borrow was created for hedging.
4. Days to cover: 6.02. On the July 31 settlement, against average volume at the time. On the 227 million share days that ratio collapses, which is exactly why the reaction was as sharp as it was.
5. Liquidity at $984 million against a business that just produced $81 million of adjusted EBITDA in a quarter. Comfortable for now, not indefinitely.
Where we think it goes
Grinds higher on execution, about 40%. The turnaround is measurable and the comparisons get easier. This is the base case precisely because it needs nothing dramatic.
Round-trips the move, about 35%. An 89% run in six sessions on 10x volume is not a valuation re-rating, it is a positioning event. The August 13 reversal of 16% is what that looks like starting.
Re-rates hard on a second beat, about 15%. If the next quarter confirms the EBITDA trend, the stock is not expensive against $2.4 billion of quarterly revenue.
Financing pressure returns, about 10%. PIK interest and a first-lien claim ahead of equity is a structure that gets uncomfortable if the operating trend stalls.
The bottom line
This one is different from most stocks that move 89% in a week, because the business genuinely improved. Revenue up 10% on a smaller fleet, a $63 million EBITDA swing, and the first GAAP profit in a long while are not a press release, they are a quarter.
But the move was amplified by a float that is half locked up and a short position that everyone is quoting without reading how it was built. A meaningful part of that 59% was manufactured in June, on purpose, so that $350 million of expensive debt could be placed.
The turnaround is the reason to be interested. The positioning is the reason it moved this fast. Confusing the two is how people buy the top of a squeeze and call it a thesis.

Notes on the numbers
Quarterly figures are as reported by Hertz on August 6, 2026. Short interest of 103,219,503 shares with 6.02 days to cover is the July 31, 2026 settlement, up from 97,539,992 on July 15. The implied float of approximately 174,995,924 is the 356,451,393 shares outstanding less the 181,455,469 held by the Knighthead and Certares entities, and is therefore an estimate: it does not adjust for other long-term holders, so the true tradeable float is smaller and the short percentage correspondingly higher. Prices, volumes, the 52-week range and the 20-day average volume are from The Desperate Trader's own market data. The characterisation of part of the short interest as convertible-arbitrage hedging follows from the share lending agreement disclosed in the June 26 prospectus; the published short interest figure is not broken down by motive and no such breakdown is public. Probability estimates are our opinion.
