Bears Pile In: Chewy, Wix Lead the Week's Movers

Short sellers had a busy week. Chewy and Wix.com posted the biggest increases in short interest among large-cap US stocks over the past seven days.

Chewy's bears keep building. Short interest hit 52.3% of free float — up 4.6 percentage points in just one week. Earnings are approaching, and ORTEX data shows zero borrow availability, meaning new shorts are struggling to find shares. That squeeze setup is real.

Wix jumped sharply. SI % FF rose from 11.5% to 17.8% in seven days — a 6.2pp move. That's one of the fastest buildups seen in the $3bn software name this year.

Lululemon took a hit. LULU cratered 17% after a Q2 miss. Short interest sits at 10.2% of free float. With analysts cutting targets across the board, bears look well-positioned.

Roku shorts are building. ROKU SI % FF stands at 9.0% as the Street turns cautious. Borrow remains cheap at 0.4% APR — room for more shorting.

Reddit defies the bears. RDDT shorts hold 15.4% of free float, but borrow is loose with availability at 280% of SI. Bears are in, but conditions aren't tight enough for a classic squeeze yet.

Wolfspeed remains extreme at 75.3% SI % FF, adding another 2.1pp this week amid a 49% three-month price collapse.
