Bears Circle CoreWeave as Chewy Holds the Top Spot

Short sellers have been busy this week. The data as of 19 October shows some clear moves worth watching.

CoreWeave saw the sharpest rise among large-cap names. Its short interest jumped 3.1 percentage points in seven days to 22.2% of free float. The AI cloud company, which reported earnings this week, now has 138% availability of short interest, meaning borrowing is still easy. Bears are pressing the bet.

Chewy remains the most shorted mid-cap US stock. Nearly 90% of its free float is sold short. That number crept up another 2.5 points over the past week, a level that would typically screen as a short squeeze candidate.

MicroVision is grabbing retail attention. Wikipedia views hit 10 standard deviations above the stock's own history on 19 October. Its cost to borrow stands at 102%, and availability is just 13% of short interest, making new short positions very expensive to establish.

Tesla shorts remain light at 2.5% of free float. German car registration data, a dataset that leads Tesla revenue by 43 days, is running 269% above year-ago levels for the same quarter. That is a strong signal heading into today's earnings report.

American Airlines was the biggest liquid mover. Short interest rose 2.2 points to 14.9% of free float. On the other side, Medtronic saw shorts cut by 5 points to 5.5%, one of the largest covers of the week.
