Bears Pile Into Braveheart, RUM Squeeze Risk Rises

Short sellers dramatically lifted bets against BRVE this week. SI % of Free Float jumped to 352% — up from 192% just seven days ago, a gain of 161 percentage points. That signals heavy synthetic short positioning in the newly listed pharma name.

RUM is the social-media story of the day. ORTEX data shows utilisation hit 93.77%, near its 52-week high. Available shares to borrow are just 7.3% of short interest — a razor-thin cushion. With SI at 18.1% of free float and availability drying up fast, a short squeeze is increasingly plausible.

WOLF remains one of the most shorted large-cap names. The silicon carbide chipmaker carries 80.7% SI % FF with zero availability — bears hold the line and there are no shares left to borrow.

FLWS sits at 79.5% SI % FF on a market cap of just $105M. Days to cover hit 31, making any positive catalyst dangerous for shorts.

CHWY shows 74.2% SI % FF but with 405% availability — shorts face no squeeze pressure here despite the high headline number.

Among week-over-week movers, SCTX and YSS both saw SI jump over 12 percentage points — worth watching as catalysts approach.
