Bears Pile In: Five9, SOUN, Solid Bio in Focus

Short sellers are moving fast. ORTEX data as of August 3 shows notable shifts in bearish positioning across several names.

SLDB leads the weekly movers. Solid Biosciences saw its SI % of free float jump +7.9 points to 39.6% in just seven days. That's a sharp build with no corresponding share price bounce to squeeze against.

FIVN (Five9) is another fresh target. SI climbed from 11.1% to 13.7% of free float over the week — a 2.6-point rise. The cloud contact-center firm has been under pressure all year.

On the structural shorts list, CHWY remains extreme. Chewy sits at 81.3% SI % FF — yet borrow costs are just 0.4%. That high availability (385% of SI) means shorts can still find stock to borrow easily.

SOUN tells the opposite story. SoundHound AI carries 42.7% SI % FF with a 13.8% cost to borrow and zero shares available. Any squeeze catalyst here would hit hard.

EVCM (EverCommerce) tops the short-score rankings. Borrow costs hit 60.1% APR — the highest among liquid names. That's a massive carry cost for shorts holding the position.

LCID (Lucid Group) mirrors the story. CTB sits at 59.6% with near-zero availability. Bears are paying dearly to stay short.

On the covering side, TNGX (Tango Therapeutics) saw SI fall 3.8 points to 56.1%. WOLF (Wolfspeed) shed 2.8 points to 78.1%.
