Bears Pile Into Auto Rentals and Chewy

Short sellers have been busy this week. The biggest 7-day jump came from WYFI (WhiteFiber), where SI % of Free Float leapt 14 percentage points to 53.4%. Shares to borrow cost over 7% annually and availability is scarce.

The rental car sector is drawing heavy fire. HTZ (Hertz) now sits at 84.6% SI % FF — up nearly 10 points in a week. Rival CAR (Avis Budget) climbed 7 points to 36.2%. Bears see structural stress in the sector.

CHWY (Chewy) jumped 10 points to 82.4% SI % FF. That puts it among the most shorted large-caps in the US market. Availability remains high at 460%, so shorts can still get in easily.

GRPN (Groupon) hit 74.3% — up 8.6 points — despite a 96% price surge over three months. Short sellers are doubling down against the rally.

On the social buzz front, PLTR (Palantir) just reported earnings and short interest sits at just 3.3% of FF — bears are thin on the ground. GME (GameStop) remains at 13% SI FF. Options activity spiked recently but has since collapsed, per ORTEX data. LCID carries a punishing 70% cost to borrow with 34% SI FF — one of the priciest shorts in the market right now.
