Short sellers are moving fast. Data as of April 30 shows sharp shifts across several names, with a few standout movers that traders should watch closely.
ONCO (Onconetix) tops the leaderboard for weekly short interest change. SI jumped from 14% to 214% of free float in just seven days. That is an extreme reading — and a classic short squeeze setup if buying pressure builds.
WOLF (Wolfspeed) sits at 50% SI % FF, up 4.2 percentage points on the week. The semiconductor name has been under pressure for months. Bears are still adding.
WEN (Wendy's) climbed to 31.7% SI % FF, up 4.2pp. Fast food is rarely a short-seller favourite. This move stands out.
FIG (Figma) hit 24.9% SI % FF, gaining 6.2pp — the biggest large-cap weekly jump in the dataset. The recent IPO is drawing heavy short interest fast.
CAR (Avis Budget) holds 64.8% SI % FF. HTZ (Hertz) sits at 43.4%. Both car rental firms remain deeply shorted amid EV fleet write-down concerns.
TNGX (Tango Therapeutics) carries 56.6% SI % FF despite an 86% price gain over three months — a live short squeeze candidate.
SMR (NuScale Power) rose to 21.8% SI % FF, up 4.4pp. Nuclear enthusiasm hasn't shaken the bears.
