Bears Pile In: Short Sellers Target Biotech and Semis

Short interest data through 2 November shows bears adding to positions across several mid-cap names, with one semiconductor stock sitting at extreme levels and a Macau gaming play drawing fresh attention.

WOLF remains the most heavily shorted name of meaningful size. Short interest stands at 88.3% of free float. Availability is effectively zero, meaning borrowing new shares is nearly impossible. The silicon carbide chipmaker has shed 14% over the past three months. Bears see no sign of retreating.

EVCM carries the highest short score on the board at 97. Cost to borrow hit 92% APR. Only 0.2% of shares are available relative to existing short interest. That is an extremely thin cushion. Any positive catalyst could force rapid covering.

The biggest mover of the past five days is BRVE. Short interest jumped 6.4 percentage points to 42.4% of free float. The biotech crossed that threshold in just five days, the largest single-week jump among stocks above $500 million in market cap.

PRG and CSV each saw short interest rise roughly 3.8 percentage points. Neither name is widely followed, making the sharp build notable.

On the other side, ABR saw its short interest fall 2.9 points to 19.1%. Shorts are trimming exposure to the mortgage REIT. QNT dropped 3.3 points.

LVS saw short interest tick up 1.8 points to 8.6%. Macau VIP baccarat gross gaming revenue hit MOP 16,906 million in Q3 2026, the largest third quarter in six years, according to ORTEX Alt Data. Bears appear unconvinced the strong Macau data will sustain.

SharkNinja's S&P 500 inclusion odds jumped to 39% overnight per ORTEX Index Rebalance Radar, up from 7%. Potential forced buying of $3.9 billion could squeeze any shorts caught on the wrong side.
