Short Sellers Circle Hertz and Chewy

Hertz is now one of the most pressured names in the market. Short interest hit 75% of free float as of July 23. That's up nearly 5 percentage points in just one week.

Chewy is close behind. SI % FF climbed to 72.4%, up 5.8 points over seven days. Both names appear in this week's high-impact news flow, alongside a peak earnings season calendar.

The biggest weekly mover is Columbia Financial. SI jumped from 5.3% to 27.6% of free float. That's a 22-point spike in seven days — the sharpest rise among mid-cap US stocks.

Wolfspeed stays in focus. SI stands at 80% of free float, with a cost to borrow near 10%. The chip maker has been a persistent short target amid restructuring concerns.

On the meme front, GameStop sits at 13.6% SI and Tesla at just 2.7%. Neither shows significant movement.

Sensei Biotherapeutics holds the highest short score on ORTEX at 99.2, with SI above 118% of free float and a CTB of 223%. Availability is just 17% — squeezing room to add more shorts.

SpaceX's unlisted vehicle SPCX also saw a 4.1-point SI rise this week to 31.7%, worth watching as sentiment shifts.
