Short sellers pushed MMED (MiniMed Group) to a 78.6% short interest as a percentage of free float as of October 1. That is up 10 percentage points in just seven days. Borrow costs sit at nearly 20% APR. Availability has collapsed to just 0.6% of short interest, making new short positions extremely hard to open.
TLN (Talen Energy) is the standout mover among large-caps. Short interest climbed from 6.1% to 12.1% of free float in a week, doubling in size. At a $15.5 billion market cap, that is a meaningful directional bet against the nuclear power generator.
WOLF (Wolfspeed) remains one of the most heavily shorted mid-caps on US exchanges. SI sits at 80.5% of free float, with zero shares available to borrow. That hard-to-borrow status signals deep conviction from existing shorts with no easy path to add more.
HTZ (Hertz) holds at 70.5% short interest with no borrow availability either. Rental car demand data continues to weigh on the name.
On the other side, GME (GameStop) grabbed attention on social platforms after CEO Ryan Cohen bought 700,000 shares at $24.41 on October 2. Short interest in GME stands at 6.5% of free float, relatively low. Borrow is cheap at 0.37% APR, suggesting the squeeze-fuel setup is limited for now.
