Bears Circle Wolfspeed as WBI Shorts Double

Short sellers made bold moves this week. Two names saw dramatic spikes in bearish positioning.

WBI — WaterBridge Infrastructure — is the week's standout mover. SI % of FF rocketed from 31.8% to 85.2% in just seven days. That's a 53-point jump. Bears are piling in hard on this midstream energy infrastructure firm.

WOLF — Wolfspeed — remains one of the most shorted stocks on the market. SI % FF hit 129.9%, up from 103.5% last week. Availability sits at exactly 0.0%. There are no shares left to borrow. Cost to borrow is 11.1% APR. The troubled SiC chipmaker continues to attract heavy short pressure.

On the unwind side, CAR — Avis Budget — saw shorts retreat sharply. SI % FF fell from 44.3% to 38.2% over the week. Bears covered nearly 6 percentage points.

CNXC — Concentrix — just cut FY2026 earnings and sales guidance. SI barely moved at 23.2%. But with guidance lowered again, fresh shorting interest could build fast.

Telecom space stocks are also in focus. ASTS — AST SpaceMobile — saw SI rise to 25.5%, up 3.4 points in a week. Shorts are growing more skeptical as telecom names faced heavy selling pressure Monday.

GME and TSLA remain quiet. Short interest is barely moving on both.
