Bears Pile In: Wolfspeed & CLRB in Focus

Short sellers are making bold moves this week. Wolfspeed tops the list with SI hitting 89.3% of free float — up nearly 29 percentage points in just seven days. Bears are betting hard on the chip maker. Zero shares remain available to borrow, locking in current positions.

Cellectar Biosciences is a different kind of alert. Short interest jumped 706% in one month. Cost to borrow has exploded to 323% APR — the highest in the stock's recent history. That's a punishing rate for anyone holding a short position.

Among retail favourites, BigBear.ai saw short interest climb to 29.2% of FF, up 3.2 points on the week. Strategy Inc ticked up to 12%, while GameStop sits at 15.2% — barely moved, but still heavily watched.

SMCI bucked the trend. Short interest fell 1.7 points to 14.9%, suggesting some bears are covering positions after recent price moves.

TSLA and NVDA remain lightly shorted at 2.7% and 1.2% respectively — neither a major target for short sellers right now.

The week's biggest wildcard remains Wolfspeed. With no shares left to borrow and a 252% price gain over three months, a squeeze scenario cannot be ruled out.
