Bears Circle SharonAI and Wolfspeed

Short sellers made dramatic moves this week. SHAZ (SharonAI Holdings) saw the most explosive jump. Its SI % of Free Float leapt from 12.7% to 54.6% in just seven days — a gain of nearly 42 percentage points.

WOLF (Wolfspeed) remains the standout extreme. Its SI % FF hit 103.5%, up from 87.4% a week ago. Availability has dropped to zero. Shares to borrow are essentially gone. Cost to borrow sits at 7.7% APR, a sign of high demand from short sellers.

RHI (Robert Half) also attracted fresh bearish bets. SI % FF climbed to 29.9%, up from 27.9%. Retail staffing firms face headwinds from AI disruption — a theme shorts appear to be trading.

On the squeeze side, SATS (EchoStar) saw covering accelerate. SI % FF fell from 32.0% to 29.2% in a week. SGP (SpyGlass Pharma) shed 4.3 percentage points.

Popular meme favourites stayed quiet. GME ticked up slightly to 14.1% SI % FF. TSLA held near 2.9%, essentially flat. NVDA remains lightly shorted at just 1.3%.

The week's big macro backdrop — Fed guidance uncertainty and US-China rare earth trade tensions — may be driving some of the defensive short positioning in tech-adjacent names.
