The setup: back in June, Hertz issued $350M in exchangeable senior notes (6.75%, due 2030) convertible into roughly 98M shares at $3.58. At the same time, 37M shares got lent to JPM and sold at $2.70 so the noteholders could hedge. Hertz didn't see a dime of that sale.
Here's the part that matters. The holders delta hedge the position, so as the stock climbs toward $3.58, the hedge mechanically requires more shorting. It's formulaic, not a directional bet. They're neutral, not bearish.
That's why $3 keeps acting like a ceiling. In August the stock doubled from $1.50 to almost $3.00 on a legit earnings beat (smaller loss than expected, revenue beat, solid Q3 guide) and just died there. The hedge flow absorbs rallies on autopilot, and the market front runs the known $3.58 overhang on top of it.
The squeeze math: around 115M shares short, roughly a third of the float, 8.5 days to cover. The thing is, the hedge wall is finite (delta can't go past 1.0) while buying pressure isn't. If $3 breaks decisively on real volume, you get momentum buyers plus forced covering at the same time. The wall becomes fuel.
Catalyst is Q3 earnings on November 5. Company guided positive EPS. Actually delivering profitability flips the story from "less bad" to "fixed."
Risks, because I'm not going to pretend they don't exist: $3.58 stays a structural ceiling through 2030 thanks to conversion dilution. There's class action noise from the June financing. And the business still has to execute. None of this matters if ops fall apart.
Position: 4807 shares, $10K cost basis.
