Bears Bet Big on AI Chips and SoundHound

Short sellers are making bold moves this week. SHAZ (SharonAI Holdings) saw the biggest jump — short interest leapt from 12.8% to 54.5% of free float in just seven days. That's a 42-point surge, one of the sharpest seen recently.

WOLF (Wolfspeed) remains the most heavily shorted name tracked. SI now sits at 103% of free float. Availability has dropped to zero, making new shorts nearly impossible to open. Cost to borrow is 7.6%.

AI chip firm CBRS (Cerebras Systems) saw SI climb from 25.6% to 32.4%. Bears are building positions ahead of potential volatility in the AI hardware space.

On the squeeze side, BIRK (Birkenstock) is unwinding fast. SI fell from 30.2% to 26.8% this week. The cost to borrow remains elevated at 21.4%, pressuring shorts to cover. Social chatter has picked up around the sandal brand.

ARS Pharmaceuticals dropped sharply too — SI fell over 5 points to 55%. Short covering is accelerating there.

Fox Corporation is a quieter mover, but SI ticked up 2 points to 16% this week, worth watching.
