Bears Circle: Big SI Spikes This Week

Short sellers turned aggressive this week. Several names saw dramatic increases in short interest, while a few heavily shorted stocks shed bearish bets fast.

Biggest Mover: WaterBridge Infrastructure

WBI stands out as the week's wildest shift. SI hit 85.2% of free float, up from 31.8% just seven days ago. That is a 53-point jump in a single week. Availability sits at only 12.6%. Borrow is tight.

Wolfspeed Still Extreme

WOLF remains one of the most shorted stocks in the market. SI stands at 129.9% of free float, up another 26 points this week. Cost to borrow is 11%. Availability is effectively zero. There are no easy exits for shorts here.

Lucid Group Bears Add Pressure

LCID short interest climbed to 39.4%, up 5.6 points on the week. The cost to borrow hit a striking 125.6% APR. That cost alone puts enormous pressure on short holders.

Zimmer Biomet Gets Hit

ZBH saw a sharp 32% one-week surge in short interest to 5.9% of float, per ORTEX. Shorts point to margin pressure in orthopedic implants.

Avis Budget Shorts Cover

CAR saw the opposite move. SI fell from 44.3% to 38.2% — a 6-point drop in a week. Bears are stepping back from the car rental giant.
