Bears Rush Into Cerebras, Rental Cars Squeezed

Short sellers moved fast this week. CBRS — Cerebras Systems — saw its SI % of Free Float rocket from 6.25% to 25.61% in just seven days. That is a +19.4 percentage point jump. Bears are clearly betting the AI chip newcomer is overvalued.

The rental car trade stays crowded. CAR (Avis Budget) sits at 45.8% SI % FF, up 6.2pp over the week. HTZ (Hertz) is close behind at 44.5%, adding 4.6pp. Both stocks are heavily discussed on social platforms, with squeeze-watchers monitoring them closely.

BIRK (Birkenstock) climbed to 30.2% SI % FF from 21.9% — a jump of 8.4pp. Cost to borrow hit 16.7% APR, one of the highest on the board this week.

WOLF (Wolfspeed) remains the outlier. SI % FF sits near 96% — but shorts are retreating. That squeeze pressure is real.

GRND (Grindr) added 10.2pp to reach 22.2%. SMMT (Summit Therapeutics) rose to 28%, up 5.3pp.

With CRWD (CrowdStrike) reporting earnings this week, options skew is building. Bears are active — but squeeze risk is high across several of these names.
