Bears Pile Into Dave, CoreWeave; Wolfspeed Shorts Retreat

Short sellers stepped up pressure on fintech DAVE this week. Its SI % of Free Float jumped 8.4 points in just seven days. It now stands at 28.8% of free float. The stock has tripled in 2026 — making the elevated short interest a bold bet against momentum.

AI infrastructure play CRWV also attracted fresh shorts. CoreWeave's SI rose 2 points to 18.3% of FF. Bears appear unconvinced by the $45bn market cap. Cost to borrow remains low at 0.43%, so capacity to short is ample.

Nuclear energy darling NNE saw shorts climb too. SI hit 26% of FF. Availability is tight at just 13% of SI. That squeeze pressure is building.

Auto parts giant APTV saw a sharp 2-point SI jump to 6.3%. The move tracks ongoing concern over EV supply chain disruption.

On the other side, WOLF shorts are covering. Wolfspeed's SI fell over 10 points to 119.7% of FF. The stock remains the most heavily shorted in the US. But the retreat signals some bears are locking in profits. Availability there reads at zero — there's nothing left to borrow.

FT Markets highlighted a broad chip stock rally. Intel and Micron led gains. Shorts in the sector may face headwinds if AI fervour holds.
