Short sellers had a busy week. The biggest mover was SPCX, Space Exploration Technologies, where short interest as a percentage of free float jumped from 3.65% to 26.27% — a gain of nearly 23 percentage points in just seven days. That is a striking build in a stock with a $1 trillion market cap.
HTZ remains the most shorted large name in the data. Hertz short interest hit 70.4% of free float, up from 59.4% a week ago. Availability has fallen to zero, meaning there are essentially no shares left to borrow.
FOXA also saw a notable rise. Fox Corporation's SI % FF climbed from 15.5% to 20.7% — a 5-point increase. That puts the media giant firmly on bears' radar.
On the squeeze side, NNN REIT caught attention. Its cost to borrow surged 349% in one week to nearly 2%. Short interest there remains low at 3.9% of float, but the CTB spike signals stress.
TNGX, Tango Therapeutics, sits at 69% short — just below Hertz — with availability at 582%, suggesting plenty of supply to keep pressure on.
PCT, PureCycle Technologies, holds 34.8% short with availability near zero at just 4.8%. That combination tends to attract squeeze watchers.
