Bears Swarm Car Rentals and AI Chips

Short sellers are making bold moves this week. Cerebras Systems saw the sharpest single-week jump — SI % of FF leapt from 6.3% to 25.6% in just seven days. Bears are clearly skeptical of the AI chip darling's valuation.

Car rental stocks are under heavy siege. Avis Budget sits at 45.8% SI, up 6.2 points in a week. Hertz matches it at 44.5%, up 4.6 points — with availability near zero at just 14%. Borrowing Hertz shares is getting very tight.

Birkenstock is another surprise. SI hit 30.2%, up 8.4 points. The cost to borrow stands at a steep 16.7% APR. Bears are paying a premium to bet against the sandal brand.

Grindr jumped 10.2 points to 22.2% SI. Social media chatter has been active on the stock after recent earnings noise.

On the other side, Wolfspeed — one of the most shorted stocks at 95.7% — saw shorts trim by 16.8 points. Availability is zero. Any short squeeze here could be violent.

GameStop remains in focus on social platforms at 12.8% SI with CTB of just 0.7%.
