Short sellers turned aggressive this week. GameStop saw its SI % of Free Float jump to 17.1% — up 3.5 percentage points in just seven days. That's a sharp move for a stock closely watched by retail traders. Bears are clearly not spooked by meme-stock nostalgia.
Wolfspeed tells a more extreme story. SI % FF hit 51.6%, up 3.4 points week-on-week. More than half the free float is now sold short. Availability has nearly vanished, sitting at just 0.8% of short interest. That means shorts are deeply committed — and getting new borrow is almost impossible.
SoundHound AI remains a social media favourite and carries one of the market's highest cost-to-borrow rates at 24.2% APR. Short interest sits at 37.7% of FF. Options activity in AI names has been heavy, with ARM and NVDA drawing fresh attention on the back of strong earnings momentum.
ARS Pharmaceuticals leads the biotech short table at with only 10.3% availability remaining — a squeeze setup worth watching.
In the rental car space, both Hertz at 42.9% and Avis Budget at 41.3% remain deeply shorted amid EV fleet concerns and demand uncertainty.
Crypto-linked names continue attracting bears too. Bitdeer Technologies sits at 38.2% SI % FF despite a positive EPS momentum score.
