Short sellers turned more aggressive across several names last week, with MMED topping the weekly movers list. Short interest in MiniMed Group jumped 9.5 percentage points in seven days to nearly 80% of free float. Availability stands at just 0.38%, meaning shares to borrow are almost impossible to find. Cost to borrow sits at 19%.
TLN is a fresh name on the radar. Talen Energy's short interest more than doubled from 6.4% to 11.5% of free float in a week. The nuclear power company drew attention as chip-stock volatility rattled sentiment around AI power demand. Michael Burry's comments this week that Big Tech is "spending wildly" on AI have kept energy-for-data-centres stocks in focus.
WOLF remains one of the most crowded shorts in the market. Wolfspeed sits at 81% SI of free float with zero shares available to borrow. The semiconductor company has shed 15% in three months.
HTZ is trending after hours, carrying 70% SI of free float. Cost to borrow has climbed to 13.5%. With availability at zero, any positive catalyst could trigger a sharp squeeze.
CHWY added 4.2 points over the week to reach 70% SI of free float. Bears continue to build despite ample availability at 441%, keeping squeeze risk lower than in the other crowded names.
US nonfarm payrolls hit a record 159 million jobs in September 2026, a macro backdrop that could pressure defensive shorts if consumer spending holds firm.
