Short sellers have been busy over the past week. The most striking move came in MMED, where short interest as a percentage of free float jumped 9.5 percentage points to nearly 80% of FF in just seven days. That puts MiniMed Group among the most heavily shorted stocks with real market heft in the US.
CHWY also attracted fresh bears. SI % FF rose 4.2 points to 70%. Shares have dropped 14% over three months. Short sellers appear unconvinced a recovery is coming.
Energy name TLN saw SI % FF almost double, climbing 5.1 points to 11.5%. Talen Energy has drawn attention as nuclear power stocks face rising scrutiny over costs.
On the flip side, H2O America (HTO) saw shorts cover hard. SI % FF fell nearly 10 points to under 5%. and also saw short covering of around 5 points each.
WOLF, the semiconductor name, stays in focus with SI % FF at 81%. Days to cover sit at over 11, meaning any squeeze would be painful for bears. Availability has dropped to zero.
ORTEX alt data adds context for autos bears: New York State passenger vehicle registrations fell 46% year on year in September 2026. That is the smallest September reading on record since 2024, a headwind that may be keeping short pressure on consumer-facing names.
HTZ remains heavily shorted at 70% of FF, with DTC near 8. The rental car group continues to face pressure from weak vehicle demand signals.
