Bears Press CoreWeave as HTZ Borrow Cost Soars

Short sellers have been busy this week. CoreWeave saw the sharpest rise among large-cap names. Its SI % FF climbed 4.5 percentage points over seven days to 25.7%. The AI infrastructure stock has drawn sceptics since its IPO earlier this year.

Hertz remains one of the most expensive shorts on the market. Cost to borrow sits at 155%, with availability at zero. SI % FF stands at 71.4%. Shares to borrow simply do not exist.

Wolfspeed is similarly squeezed. SI % FF is 84.4% with zero availability. The semiconductor maker has shed most of its value over three months. The short case remains aggressive.

Chewy carries 86.5% SI % FF, the highest among mid-cap names covered. Despite heavy shorts, availability is 566%, meaning bears can still find stock to borrow easily.

Levi Strauss caught fresh attention. Short interest rose 2.9 percentage points in a week to 11.6% of free float. The move comes with no immediate catalyst apparent in news feeds.

Separately, Albertsons shorts climbed 4.4 points to 23.8%. Grocery competition remains fierce.

Talen Energy sits at a modest 5.5% SI % FF, but ORTEX alt data flags a different risk. Reactor output fell 10 standard deviations below its own history as of 9 October. That is the sharpest deviation in the nuclear output dataset, a signal bears may yet price in more aggressively.

On the rebalance radar, EverCommerce faces additional pressure. Short score is at 96, with 93% cost to borrow and only 5.6% availability. Index flows could add to the pain.
