Bears Pile Into Chewy, Trucking Stocks

Short sellers turned aggressive this week. Two names stand out for fresh pressure: CHWY and KNX.

Chewy now sits at 51.2% SI % of FF — up 4.4 percentage points in just seven days. Bears are betting the pet e-commerce firm's margins remain squeezed. Shares to borrow are abundant, with availability at 537% of SI, so this trade can still grow.

Trucker Knight-Swift saw its SI % FF nearly double week-over-week, jumping from 5.96% to 10.94% — a 5 percentage point spike. Freight markets are back in focus this week as macro data looms.

On the persistent side, Wolfspeed remains a battleground stock. SI % FF stands at 74.8% with zero shares available to borrow. Short sellers are locked in and nobody is lending. Hertz is similarly constrained at 62.4% SI % FF with no availability — a classic squeeze setup if sentiment turns.

Social buzz surrounds Rocket Lab after after-hours trending. Its SI % FF is a modest 7.9%, meaning shorts here are not the driver — momentum buyers are. The stock's low cost-to-borrow at 0.4% signals little short conviction.

Keep watching CHWY and WOLF — both show classic divergence between rising short interest and constrained availability.
