Bears Pile In: Chewy, Lucid, Wolfspeed Lead Week's Biggest Short Surges

Short sellers have been busy this week. Several names saw dramatic short interest jumps in just five days — and a few carry serious squeeze risk.

CHWY tops the momentum table with SI % FF jumping to 63.6%, up 12 percentage points since September 4. That is a sharp build on an already crowded trade. Bears are clearly not done with the pet e-commerce play.

LCID saw an even sharper relative jump. Short interest leapt from 34.9% to 49.7% of free float in five days. Availability has nearly vanished — just 0.4% of SI can be borrowed right now. A news catalyst here could be explosive.

WOLF remains one of the most shorted stocks in the US market. SI % FF now stands at 83.0%, up more than 8 points this week. Availability has hit zero. Shorts are locked in — and that cuts both ways.

Also catching attention: CRL (Charles River Laboratories) saw short interest spike 28% in a single day to 5.05% of float — flagged by ORTEX News as the biggest one-day spike in weeks. The stock fell 1.9% on the same day.

LUCK carries one of the highest short scores at 94.7, with days-to-cover at 24.5 and SI at 16.7% of float. It has fallen 37% over three months.

Bond market turbulence, rising diesel costs, and a broader macro risk-off tone are likely adding fuel to bearish bets across rate-sensitive and consumer names.
