Short interest made big moves this week. Cerebras Systems saw the biggest jump. Its SI % FF surged to 32.4%. That's up from 6.3% just one week ago — a 26-point leap.
The AI chipmaker went public in late 2024. Bears are now betting heavily against it. Zero availability means no new short positions can be opened easily.
Birkenstock also attracted fresh shorts. SI % FF rose to 29.4% from 21.8%. Cost to borrow hit 18.2% — among the steepest in the market. Shorts are paying a high price to stay in that trade.
Rental car stocks remain under pressure. Avis Budget Group sits at 47.8% SI % FF. Grindr doubled its short load, jumping from 12% to 22.3% in a week.
On the other side, Wolfspeed saw a sharp short squeeze signal. SI % FF fell from 117% to 88.9% — a drop of 28 points in seven days. That's a massive cover by bears.
GameStop sits at 13% SI % FF with 84% availability. Plenty of ammo remains for short sellers — or squeeze hunters.
