Short sellers ramped up bets across biotech and semiconductor names this week. Replimune Group saw the sharpest move. Its short interest jumped 10.75 percentage points in just seven days. SI now sits at 38.1% of free float.
Wolfspeed remains a bearish favourite. SI hit 85.6% of free float — up another 6.3 points in a week. Zero shares are available to borrow. That's a stock under extreme short pressure.
CoreCivic caught fresh attention too. SI surged from 2.4% to 10.0% in a week — a more than fourfold jump. The private prison operator is now firmly on short sellers' radar.
On the squeeze side, Chewy saw SI drop 12.3 points to 63.4%. That's still high, but bears are covering. With 580% availability of SI, there's no supply crunch — yet.
Hertz keeps heavy short interest at 64.1% of FF. Cost to borrow stands at 12.1%. That makes it expensive to maintain a short position.
In the wider market, FLWS carries 76.3% SI with 27 days to cover. A short squeeze there would be violent. holds the highest short score at 90 — with CTB at nearly 15%.
