Bears Pile In: Wolfspeed Hits 106% Short

Short sellers are making bold moves this week. Wolfspeed tops the list with a jaw-dropping SI of 106% of free float — up 34 percentage points in just seven days. With zero shares available to borrow and a cost-to-borrow of 17%, the squeeze risk is real.

Carvana is the week's biggest mover by surprise factor. SI jumped from 2.1% to 10.1% of free float in seven days — a fivefold rise. Bears are clearly growing skeptical of the used-car platform's recent rally.

Lucid Group also attracted fresh shorts. SI climbed to 34.7% from 27.7% last week. The EV name remains under pressure with no clear path to profitability.

Chewy sits at 48% of free float shorted, adding 7.4 points in a week. Despite a massive 859% share availability reading, shorts keep piling in.

On the other side, KalVista Pharmaceuticals saw shorts retreat sharply. SI fell 13 points to 41%. Rumble dropped 5 points to 19.5% — short sellers backing off the video platform.

Tango Therapeutics also saw covering, with SI falling to 54.3% from 61.8%. Biotech short covering can signal improved sentiment — or simply profit-taking ahead of catalysts.
