MMED is the standout mover. Short interest hit 77.7% of free float, up from 28.1% just 30 days ago. That is a gain of nearly 50 percentage points. Shares to borrow are almost gone, with availability at just 1.5% of short interest. The cost to borrow sits at 17.9% APR.
WOLF (Wolfspeed) holds the top short position at 80.4% of free float. Availability has collapsed to zero. Short sellers have added 4.3 percentage points over the past month, with days to cover at 11.3.
HTZ (Hertz) comes in at 70.2% SI of free float, up 8 points over 30 days. Zero shares available to borrow. Cost to borrow is 8.1% APR. Bearish positioning in the car rental sector reflects ongoing stress in used vehicle values.
CHWY sits at 67.4% short. Availability here is unusually high at 447%, suggesting room for further short building. The cost to borrow is cheap at just 0.4%.
EVCM carries a short score of 95, the highest in the software sector, with CTB at 45.2% and only 1.5% availability. Days to cover stands at 22.
Meanwhile, SERV (Serve Robotics) sees 38.6% of free float short, up 5.8 points in a month, with zero availability remaining.
On the buyback front, ORTEX Alt Data shows remaining buyback authorisations hit a record $58.2bn in Q2 2026, more than double the prior Q2 best. Shares actually repurchased fell 34% year-on-year, pointing to a gap between authorised and executed. That divergence can matter where short sellers are watching for follow-through.
