Short sellers made bold new bets this week. CBRS — Cerebras Systems — saw the sharpest jump. Its SI % of Free Float surged to 27.7%, up from just 6.3% a week ago. That's a 21-point leap in seven days. Bears are clearly sceptical of the AI chipmaker's valuation.
BIRK is another mover worth watching. Short interest in Birkenstock climbed to 30.9% from 22.1%. The cost to borrow hit 19.3% APR, and availability has collapsed to near zero. Shorts are piling in but will struggle to add more.
HTZ remains under heavy pressure. Hertz short interest stands at 45% of free float, up from 39.6% last week. The struggling rental car firm continues to attract bears.
On the other side, WOLF (Wolfspeed) saw shorts retreat. SI fell to 99.8% from 118% — still enormous, but the unwinding is notable. Availability is zero, making any new short position near-impossible.
Among social favourites, GME sits at , while remains lightly shorted at . is even lower at — bulls firmly control those names.
