Short sellers made bold moves this week. Hertz leads all large-cap gainers in short interest. Its SI % of FF hit 59.2% — up nearly 11 percentage points in seven days. Borrowing shares costs 4.2% APR. Availability has dropped to zero. That is a stock under serious bear pressure.
CoreWeave is another notable mover. The AI infrastructure name saw its SI % FF climb to 28.4%, up 4.8 points in a week. Despite a $36B market cap, bears keep adding. Cost to borrow remains low at 0.5%, so the pressure could build further.
Perrigo grabbed attention after ORTEX flagged a 26.4% surge in short interest in one week. Activist short pressure drove it to 13.5% of float. The stock simultaneously rallied 13.8% — a classic squeeze setup to watch.
On the social front, Tesla and NVIDIA topped the most-searched ticker lists for H1 2026. Yet neither carries meaningful short pressure. TSLA SI sits at just 2.9% of FF. NVDA is even lower at 1.3%.
GameStop remains steadily shorted at 13.8% of FF. No big move this week. Reddit dipped slightly from 12.7% to 12.3%. Palantir stays lightly shorted at 3.6%.
The real action this week belongs to Hertz — near-zero availability and a 59% short float make it the most explosive squeeze candidate in the market right now.
