Short Sellers Chase Wolfspeed, Hertz Into July

Short sellers had a busy week. The data through June 29 shows some sharp moves heading into the second half of 2026.

WOLF leads all movers. Short interest in the beleaguered chipmaker jumped +27.5 percentage points in seven days. It now sits at 132% of free float. Availability is zero. Bears are firmly in control, and borrowing stock is getting harder by the day.

HTZ is another name attracting heavy new shorts. Hertz saw SI rise +18 points to 62.6% of free float. The car rental giant has struggled for years post-bankruptcy. Fresh short pressure signals bears still see more downside.

CRWV is drawing attention too. CoreWeave's SI climbed to 28.9% of FF, up nearly 7 points on the week. The AI infrastructure darling is one of the most-talked-about IPOs of 2025. Short sellers are growing bolder.

On the flip side, bears covered hard in CAR. Avis Budget saw SI drop 7.3 points to 39%. Bears also retreated from BIRK, down 5.8 points.

TSLA and GME remain staples of social media, but neither moved meaningfully this week. Tesla sits at just 2.9% of FF. GME holds at 13.6%. Meanwhile, STZ is buzzing — bears are easing ahead of Tuesday's earnings, per ORTEX signals.
