Bears Double Down: BRVE, WOLF Lead This Week's SI Surge

Short sellers have been busy. Braveheart Bio tops the charts with a jaw-dropping SI of 226% of free float — and it jumped another 36.5 percentage points in just seven days. That's one of the sharpest weekly short interest spikes in any stock above a $1B market cap right now.

Wolfspeed remains a bear favourite. SI sits at 82% of free float. Availability has hit zero, meaning borrowing shares is nearly impossible. That's a classic squeeze setup — shorts are fully locked in.

Smith & Wesson is a fresh entry to watch. SI climbed 4 points to 10% this week. The gun maker's stock has been under pressure, and short sellers are piling on.

Signet Jewelers also saw a jump — SI rose to 17.8%, up from 14.5% a week ago. With consumer spending under strain, shorts are betting the jeweller feels the pinch.

On the other side, Chewy is seeing early covering. SI dropped from 77.7% to 74.1% this week. Still extremely elevated, but shorts are trimming. Asana saw its SI drop 2.3 points to 26.5%.

Fabric.AI carries the highest short score of any stock — 89 out of 100 — with SI at 79% and a cost to borrow above 236%. Bears are paying a steep price to stay short there.
