Short sellers made bold moves this week. Data from ORTEX as of September 24 shows dramatic swings in short positioning across multiple names.
Biggest new short target: BRVE (Braveheart Bio) saw its short interest explode to 585.6% of free float — up a staggering 359 percentage points in just seven days. That's the sharpest week-on-week build in the market.
MMED (MiniMed Group) was another standout, with SI jumping from 38.5% to 68.3% of free float. Short score sits at a high 90.1. Availability is razor-thin at just 2.3%, which could set up a squeeze.
SPCX (Space Exploration Technologies) also attracted fresh bears. SI rose nearly 10 percentage points to 30.6% of FF over the week.
On the cover side, CHWY (Chewy) saw short interest fall from 74.1% to 67.2% — short sellers easing off despite the stock's ongoing struggles.
ARQQ (Arqit Quantum) dropped from 56.5% to , a significant 10-point retreat suggesting bulls may be gaining ground.
Chip stocks remain lightly shorted. NVDA sits at just 1.27% SI, with cost to borrow near zero — shorts have little appetite for mega-cap tech right now.
