Short sellers made sharp moves this week. CBRS (Cerebras Systems) saw the biggest jump. SI % FF leapt from 6.3% to 27.7% — a gain of over 21 percentage points in seven days. Bears are piling in fast on the AI chip hopeful.
BIRK (Birkenstock) is also drawing attention. Short interest climbed nearly 9 points to 30.9% of free float. Cost to borrow hit 19.3% APR — a sign shorts are paying up to keep bets open.
HTZ (Hertz) added 5.4 points this week and now sits at 45% SI % FF. The car rental group remains one of the most shorted mid-caps in the US market.
On the other side, WOLF saw short covering. SI % FF dropped 18 points to 99.8%. That is still near-total float shorts, but the retreat is notable. CRSP (CRISPR Therapeutics) shed 5 points to 22.2%, suggesting some bears are stepping back from the gene-editing trade.
Social chatter is buzzing around NVDA and after Jim Cramer flagged both as "good money" being sold to chase the SpaceX IPO. Neither has high short interest — NVDA at 1.2% and AAPL at 1.1% — but any pullback could change the picture fast.
GME holds at 13% SI % FF. Meme traders remain watchful.
