Bears Tighten Grip on Wolfspeed & Carvana

Short sellers made bold moves this week. WOLF saw the sharpest surge in bearish bets among mid-cap stocks — SI % of Free Float jumped from 57.6% to 80.1% in just seven days. That's a 22.5 percentage point spike. Availability sits at exactly zero, meaning there are no shares left to borrow. Bears are all-in on the troubled semiconductor firm.

CVNA drew fresh short interest too. Carvana's SI % FF leapt from 2.1% to 10.2% — an 8-point jump in one week. The used-car platform has been a battleground stock for years. Bears appear to be re-engaging after a long squeeze-driven rally pushed the market cap past $50bn.

LCID remains heavily targeted. Lucid's SI % FF rose to 34.6%, up 7 points week-on-week. Availability is near zero at 0.1%. With cost to borrow at 10.6%, short positions are expensive to hold — yet bears aren't backing down.

On the squeeze side, RUM saw short interest fall 5.3 points to 19.9% of FF. Rumble's bearish positioning is unwinding. KALV — KalVista Pharmaceuticals — shed 12.8 points, the biggest short cover of the week.

LYFT also caught attention. SI % FF hit 29.2%, up nearly 5 points. The ride-hailing stock has been buzzy on social platforms this week amid ongoing profitability debates.
