Bears Pile Into Cerebras, Hertz, and Grindr

Short sellers made bold moves this week. CBRS (Cerebras Systems) saw the biggest jump — its short interest as a percentage of free float leapt from 6.25% to 25.48% in just seven days. That's a 19-point spike on the AI chipmaker. Bears are questioning its $8.2bn valuation amid intense rivalry with NVDA.

HTZ (Hertz) remains a target. Short interest hit 43.7% of free float, up from 39.4% last week. Availability is tight at just 25%. That squeeze setup is building.

GRND (Grindr) is a notable new entrant. SI jumped from 12.9% to 21.5% in a week — an 8.6-point move. BIRK (Birkenstock) also saw a sharp rise, climbing from 21.9% to 29.7%.

XOMA holds the extreme end. Its short interest sits at 90.1% of free float. That's not new — but a 10-point weekly rise keeps it in focus.

On the macro side, AES short interest surged 31% week-on-week to 3.4% of float. BDC (Belden) jumped 26.5% in a week.

Meanwhile, TSLA and META remain lightly shorted at 2.8% and 1.5% respectively — social buzz hasn't translated into short conviction there.

This is not financial advice.
