Bears Pile Into Braveheart, Smith & Wesson

Short sellers made bold moves this week. BRVE — Braveheart Bio — stands out as the most extreme case in the market. Its short interest hit a staggering 226% of free float, up 36.5 percentage points in just seven days. That means shorts dwarf the entire available float. Availability has dropped to near zero, making new positions almost impossible to open.

WOLF — Wolfspeed — remains deeply under pressure. SI sits at 82% of FF with zero availability reported. The semiconductor firm has shed 55% in three months. Bears show no sign of backing off.

CHWY tells a different story. Short interest fell 3.5 points to 74% of FF this week. That's still enormous, but the retreat hints at some short covering — a squeeze risk worth watching.

SPCX — SpaceX — is also seeing shorts pull back. SI dropped nearly 5 points to 20.7% of FF ahead of a September 22 event. Shorts appear cautious near a potential catalyst.

New entrants caught attention too. SWBI — Smith & Wesson — saw SI jump 4 points to 10% of FF. SIG — Signet Jewelers — rose 3.4 points to 17.8% as retail headwinds persist.
