Short sellers made aggressive moves this week. Wolfspeed tops the large-cap movers. Its short interest hit 59.7% of free float — up nearly 9 percentage points in just seven days. Availability is at zero, meaning borrowable shares are essentially gone.
Carvana saw an even sharper relative jump. SI leapt from 2% to 8.8% of free float in a week — a more than fourfold increase. Bears are circling the used-car platform despite its $56bn market cap.
Transport giant J.B. Hunt is grabbing attention too. ORTEX data flagged a 31% single-day jump in short interest, with the put/call ratio spiking to 1.26. Traders are clearly turning bearish on freight.
In extreme-short territory, ARS Pharmaceuticals sits at 64.4% of free float shorted. Availability is just 3.9% — shorts are deeply committed and new bears have almost nowhere to borrow.
Celsius Holdings dropped 10% today. Its SI sits at 11.1% of free float. With availability at 193%, shorts can still pile in — and they may.
Meanwhile, STAAR Surgical remains one of the most squeezable names, with SI at 112% of free float and no obvious catalyst to relieve the pressure.
