Bears Pile In: WIX, CHWY Lead SI Surge

Short sellers made bold moves this week. Wix.com tops the movers list with SI jumping from 11.5% to 17.8% of free float — a +6.2pp spike in just seven days. Earnings are on the radar for the web-platform firm. Bears are clearly not convinced by the outlook.

Chewy sits at a hefty 52.3% SI % FF, up 4.6pp over the week. Availability is enormous at 544%, meaning shares to borrow remain plentiful. Short sellers keep pressing despite the pet-retailer's recent price gains.

Tenable Holdings jumped from 9.1% to 13.5% in a week, a 4.4pp rise. The cybersecurity firm faces growing bear pressure ahead of results.

Among the structural high-shorts, Wolfspeed sits at a staggering 75.3% with zero shares available to borrow. Hertz is similarly seized up at 61.7% with 0% availability and a 7.3% cost to borrow — squeeze conditions are building.

ChronoScale carries a steep 43.5% cost to borrow with SI at 19%, making it one of the most expensive shorts on the board right now.

lululemon at 9.9% SI % FF is trending in news today as analysts slash targets. Bears are watching closely into earnings next week.
