Bears Pile In: Five9, BridgeBio Lead SI Movers

Short sellers made notable moves in the week ending August 4. The clearest trend: bears are building positions in tech and biotech while cutting exposure in semiconductors.

Five9 saw the biggest jump among mid-cap names. Its SI % of Free Float rose to 15.0%, up nearly 3.7 points in seven days. The cloud contact-center software firm has been under pressure as enterprise AI spending shifts to in-house solutions.

BridgeBio Pharma remains one of the most extreme shorts on the market. Its SI hit 738% of free float — a figure explained by a heavily concentrated float. It climbed another 9 points in just one week.

On the semiconductor side, Wolfspeed shorts are actually pulling back. SI dropped 3.5 points to 77.1% of free float. The stock has fallen over 26% in three months. Some bears may be locking in gains.

Chewy stays heavily shorted at 78.4% of FF, but availability remains high at 459% of SI — meaning borrow is easy and a squeeze looks unlikely near-term.

EverCommerce carries the highest ORTEX short score at 95.9. Its cost to borrow hit 56.4% APR. Availability has collapsed to just 0.7% of SI — a warning sign for any remaining shorts.

Hertz holds at 82% SI with zero shares available to borrow. Days to cover stands at 12. A catalyst could make things uncomfortable fast.
