Bears Pile Into Space, Pharma Stocks

Short sellers made big moves last week. BRVE — Braveheart Bio — saw the most extreme reading, with SI jumping to 352% of free float, up 161 points in seven days. That level reflects aggressive synthetic short positioning rather than a simple directional bet.

Elsewhere, YSS (York Space Systems) saw shorts nearly double, rising from 15.1% to 27.4% of free float in a week. SPCX (Space Exploration Technologies) climbed to 29.9% SI, adding 7.9 points. The space sector is clearly attracting skeptics.

MMED (MiniMed Group) hit 42% SI, up 8.5 points. Its short score sits at 85, with cost to borrow at 17%. Shorts are paying up to hold this position.

On the squeeze watch list, CHWY remains deeply shorted at 74.2% of free float, but pressure is easing — shorts trimmed slightly over the week. LCID holds steady at 50.4%, flat on the week. HTZ ticked up 2.5 points to 69.3%, with zero shares available to borrow — a warning sign for late shorts.

EVCM leads on short score at 94, with cost to borrow at nearly 39% APR and near-zero availability. That combination makes it one of the most expensive shorts in the market.

MGM came into focus after news Barry Diller withdrew a bid. Short interest is modest at 10%, leaving room for further positioning if the deal void weighs on sentiment.
