Bears Tighten Grip on Wolfspeed and Replimune

Short sellers made bold moves this week. Two names stand out above all others.

WOLF — Wolfspeed — now carries 87% short interest as a percentage of free float. That already made it the most shorted stock with a market cap above $500M. Bears added another 7.6 percentage points in just seven days. Zero shares are available to borrow. The semiconductor maker has shed 41% over three months, and short sellers see no floor yet.

REPL — Replimune Group — saw the biggest weekly jump. SI % FF leapt from 26% to 38%. That is an 11.9 percentage-point rise in one week. Availability sits at 810% of SI, meaning plenty of room for more short selling if bears choose to pile on.

CHWY — Chewy — tells the opposite story. Bears covered hard. SI % FF dropped from 77% to 65% in a week. That's a sharp 12-point fall.

SPCX — SpaceX — also saw notable covering. SI % FF fell from 28% to 19.5%.

On the cost-to-borrow front, EVCM — EverCommerce — leads at 39.5% APR. That signals extreme difficulty borrowing shares. With chip stocks sliding on bond yield fears, watch heavily shorted semis closely.
