Bears Pile Into Wolfspeed and WaterBridge

Short sellers have been busy this week. WaterBridge Infrastructure saw the sharpest SI jump. Its short interest as a % of free float leapt from 31.8% to 85.2% in just seven days — a 53-point surge.

Wolfspeed remains the most extreme case. SI hit 129.9% of free float. Cost to borrow stands at 11.1%. Availability is zero. Bears cannot easily exit this trade.

FuelCell Energy drew fresh attention on social platforms. SI surged 26% in one week to 14.6% of float. The cost to borrow tripled to 1.67%. That cost spike signals tightening supply of shares to borrow.

On the other side, shorts are covering Baker Hughes. SI dropped 30% in one week to just 2.0% of float. Cost to borrow fell to 0.35%. That is a significant capitulation by bears in a large-cap energy name.

Avis Budget Group also saw notable covering. SI dropped 6 points to 38.2% of float. That stock remains heavily shorted overall, but the direction is shifting.

The biggest SI movers this week lean bearish on smaller names. New shorts on GeneDx Holdings and Hinge Health both jumped over 6 points. Both are recent IPO-vintage stocks with high retail interest.
