Short sellers made dramatic moves this week. Biodexa Pharmaceuticals stands out as the most extreme mover. Its SI % of Free Float exploded to 1,771% — up from 111% just seven days ago. That's a jaw-dropping 1,660-percentage-point jump in a single week.
Wolfspeed is the headline story among larger stocks. The chipmaker's short interest hit 60.4% of free float, rising nearly 10 points in seven days. The stock is up 196% over three months. Bears are betting hard the rally is overblown.
SoundHound AI carries 37.5% SI of FF with a cost to borrow of 22%. Short sellers are paying a steep premium to stay in their positions.
In the rental car space, Hertz remains deeply shorted at 43.9% of FF, while Avis Budget sits at 35.7%. Both face pressure from EV fleet costs and weak consumer travel.
Wheels Up has near-zero availability at just — meaning shorts have almost no room to add new positions. With 174% SI of FF and a 9.2 days-to-cover, a squeeze remains possible.
Among biotech names ahead of prints, BigBear.ai shorts are holding firm into Q1 earnings. Veeva Systems saw a notable 3.4-point SI jump to 7.2% — unusual for a mid-cap software name.
