Short sellers turned aggressive on several names this week. The data as of August 13 shows sharp moves in both biotech and semiconductors.
REPL — Replimune Group — saw the biggest weekly jump. Its SI % FF leapt +10.4 percentage points to 37.8% in just seven days. Biotech peer CCCC — C4 Therapeutics — also saw SI climb +8.3pp to 31.1%.
The most crowded short remains WOLF — Wolfspeed. Bears hold 85.2% of its free float short. Availability is now zero. That means no new shorts can easily be added. SI rose another +6.9pp this week alone. With a cost to borrow at 3.8%, pressure is building.
CXW — CoreCivic — stands out as a surprise. SI % FF surged from just 2.3% to 10.0% in one week. That is a fourfold increase. Prison operators are in focus as policy risk grows.
On the high short-score leaderboard, EVCM — EverCommerce — carries a 93.6 ORTEX short score. Its cost to borrow hit 40%. That is among the highest for mid-caps.
— SoundHound AI — sits at 40% SI % FF. CTB is 10.5% and availability is zero. Squeeze risk is real.
Meanwhile, mega-caps stay quiet. NVDA and TSLA have SI % FF below 3%, with borrowing costs near zero. Bears are not the story there — bulls are.
