Bears Pile Into AI, Autos, and Chips

Short sellers made bold new bets this week. Three names stand out for speed and size of move.

SharonAI Holdings (SHAZ) saw the biggest jump. SI % FF rocketed from 12.8% to 54.5% in just seven days — a gain of nearly 42 percentage points. That is an extraordinary move. Availability of shares to borrow sits at just 5.3%, making a squeeze scenario very plausible.

Cerebras Systems (CBRS) also attracted fresh shorts. SI % FF climbed to 32.4%, up 6.8 points week-on-week. Availability is zero. Bears are fully committed and borrow is essentially shut.

Wolfspeed (WOLF) remains one of the most extreme short setups in the market. SI % FF tops 103% of free float. Availability has hit zero. Cost to borrow is 7.6%. No shares left to find — bears are trapped.

On the covering side, Birkenstock (BIRK) shorts retreated. SI % FF fell from 30.2% to 26.8%. Still elevated, but the trend reversed. Cost to borrow remains high at 21.4%, which likely pressured some shorts to exit.

Frontier Group (ULCC) also saw covering. SI dropped from 36.1% to 33.6%. Availability is very high at 239%, signalling bears could easily rebuild if needed.

Avis Budget (CAR) hit 48.2% SI % FF — up 2.3 points this week. With half the float shorted and moderate availability, the car rental giant remains a key watch for squeeze risk.
