Bears Pile Into Wolfspeed and Avis

Short sellers stepped up pressure on several names this week. Wolfspeed tops the most-shorted list with a staggering 100.9% SI % FF — meaning shorts exceed the entire free float. That figure rose another 8.6 percentage points in just seven days.

SharonAI Holdings saw the biggest weekly jump. SI % FF rocketed from 12.4% to 50.7%, a 38-point swing in a week. That is an extraordinary build-up. Avis Budget also attracted fresh shorts, climbing to 48.1% of free float, up nearly 8 points from last week.

AI chipmaker Cerebras Systems is drawing short sellers too. SI % FF hit 31.8%, up 6.4 points over seven days. Bears appear to be questioning its post-IPO valuation as competition from NVIDIA intensifies.

On the squeeze side, Kohl's shorts retreated 2.6 points to 21.8%. HP Inc. saw a 1.7-point drop to 9.3% — a modest but notable unwind.

Meanwhile, the meme crowd's favourites look quiet. GameStop sits at 12.7% SI % FF. AMC trades at just 8.3%, with cost to borrow under 0.5% — little urgency for either side.
