Bears Circle CoreWeave as Short Bets Jump

Short sellers pushed hard into CoreWeave last week. The AI cloud infrastructure firm saw its short interest jump 3.66 percentage points in seven days to 23.7% of free float. That is the biggest week-on-week move among US stocks with a market cap above $500 million.

Sturm Ruger followed close behind. Short interest rose 3.34 percentage points to 10.65% of free float, an unusual build in the firearms maker. Legend Biotech also attracted fresh shorts, up 3 percentage points to 22.1%.

On the other end, EverCommerce carries the highest short score among mid-cap names. Its cost to borrow stands at 95.5% APR. Availability sits at just 1.5% of short interest, meaning shares to borrow are nearly exhausted.

Chewy remains one of the most shorted names by free float at 89.2%. Availability is abundant at 518%, so no squeeze pressure is building there yet.

Supernus Pharmaceuticals is drawing retail attention. ORTEX data shows Wikipedia traffic running 7.3 standard deviations above its 90-day average today, a signal that often precedes sharp moves.

Taiwan export orders hit a record $114 billion in September, up 62% year-on-year. That data point matters for the chip supply chain. TSLA short interest sits low at 2.6% of free float, while NVDA is even lighter at 1.4%, suggesting bears are not pressing the big-cap tech names.
