Bears Double Down on Wolfspeed and WaterBridge

Short sellers made bold moves this week. Two names stand out as clear targets for bearish conviction.

WaterBridge Infrastructure saw the sharpest spike. Its short interest jumped 53 percentage points in just seven days. It now sits at 83% of free float. That is an extraordinary build in a single week.

Wolfspeed remains the most shorted large US stock. Bears pushed it to 113% of free float — up 15 points week-on-week. Its cost to borrow sits at 9.4%. That is expensive but still manageable for determined shorts.

Cerebras Systems is another name bears are loading up on. SI% rose 6.6 points to 38% of free float. The AI chip company IPO'd late last year and shorts have been relentless.

On the other side, Salesforce saw bears retreat. SI fell more than 2 points to just 4%. EchoStar also saw notable covering, dropping 3.3 points.

Social media favourite SoundHound AI carries a 11.5% cost to borrow. That is the highest among major shorted names. Its SI of 38.5% is unchanged week-on-week but the borrowing cost signals fresh pressure. FuelCell Energy jumped today on a 380MW data centre deal — short sellers there may be feeling the squeeze.
