Bears Load Up as Earnings Week Looms

Short sellers sharpened their bets heading into the busiest earnings week of 2026. The biggest mover was WYFI (WhiteFiber). Its short interest jumped +14 percentage points in seven days. It now sits at 53.4% of free float. Cost to borrow hit 8.9%, signalling growing conviction among bears.

The car rental trade is back in focus. HTZ (Hertz) remains the most shorted large name at 84.6% SI — up nearly 10 points on the week. Peer CAR (Avis Budget) also climbed sharply, adding 7.1 points to reach 36.2% of free float. Both names appear in this week's earnings calendar.

CHWY (Chewy) rounds out the trio of big SI movers, jumping to 82.4% from 72.4% a week ago. It too reports earnings this week, and bears appear positioned for disappointment.

GRPN (Groupon) stayed firmly in focus on social platforms. Its 3-month price surge of +96% has attracted short sellers. SI now stands at 74.3% of free float.

On the squeeze watchlist, EVCM (EverCommerce) tops the short score table at 95.7. Cost to borrow is an elevated 40.3%, with availability near zero. That's a fragile setup for shorts if any positive catalyst emerges.
