Bears Pile Into CoreWeave; Wolfspeed Stays Under Siege

Short sellers added aggressively to CoreWeave positions this week. Short interest hit 24.1% of free float on October 21, up 3.7 percentage points in just seven days. The AI cloud computing firm carries a $28.5bn market cap. Bears are clearly skeptical of its valuation.

Wolfspeed remains one of the most punishing shorts on the market. SI sits at 85.5% of free float with zero shares available to borrow. The semiconductor maker has shed 16% over three months. Days to cover stand at nearly 10, a level that makes any squeeze technically possible but practically difficult.

Chewy stays extreme at 89% short interest but saw a slight 3.6 percentage point pullback this week. Cost to borrow is a modest 0.4%, suggesting shorts are comfortable holding.

Levi Strauss caught attention with a 2.7 point rise in SI to 11.7% of free float. The denim brand has quietly attracted more bearish interest over the past week.

1-800-Flowers holds the most punishing days-to-cover reading among mid-size names at 25.4 days, with SI at 78.8% of free float and availability down to just 30%.

Taiwan export orders hit a record $114bn in September, up 62% year-on-year. That tailwind sits squarely behind semiconductor demand, which makes the sustained short pressure on Wolfspeed all the more striking.
