Bears Target Cerebras, Hertz, and Birkenstock

Short sellers made aggressive moves this week. CBRS saw the sharpest jump — SI % of Free Float leapt from 6.25% to 25.48% in just seven days, a rise of over 19 percentage points. The AI chip company had been a market darling. Bears are now firmly in the picture.

BIRK tells a similar story. The sandal maker's short interest climbed nearly 8 points to 29.74% of free float. Its cost to borrow hit 21.2% — one of the highest on the market right now. Availability is near zero at just 0.04% of SI. That combination signals very strong bearish conviction and very little room to build new short positions.

HTZ remains the most heavily shorted large name. SI sits at 43.7% of free float. It climbed another 4.3 points this week. Availability is just 25%, meaning supply is tightening.

GRND saw its short interest surge 8.6 points to 21.48%. SMMT and SAM both saw increases above 3.7 points. Biotech and consumer names are clearly in short sellers' crosshairs.

US tech stocks fell broadly amid Iran tensions and pre-SpaceX IPO nerves. That backdrop may be encouraging fresh short positioning across growth names. Watch these stocks closely.
