Bears Pile Into Cerebras and Rental Giants

CBRS is this week's standout mover. Short interest jumped to 25.6% of free float. That's up from just 6.3% seven days ago — a 19-point leap in one week.

The rental car sector is drawing heavy fire. CAR (Avis Budget) sits at 45.8% short, up 6.2 points in a week. HTZ (Hertz) is close behind at 44.5%, up 4.6 points. Availability on Hertz is razor thin at just 14% of short interest — a sign that new short positions are getting harder to open.

GRND (Grindr) saw its SI jump 10 points to 22.2%. BIRK (Birkenstock) climbed 8.4 points to 30.2%.

On the other side, WOLF (Wolfspeed) shorts retreated sharply. SI fell 16.8 points to 95.7%. That's still extreme, but the direction matters.

KDP (Keurig Dr Pepper) is seeing fresh short bets as its June 16 earnings approach. COIN sits at 11.4% with options signaling elevated risk ahead of its print.

Social favourites GME holds steady at 12.8%. TSLA remains lightly shorted at 2.75%.
