Bears Pile In: Wolfspeed, Cerebras, Freddie Mac in Focus

Short sellers intensified bets across several names last week. Wolfspeed tops the most-shorted table with 88.6% of its free float sold short. That figure climbed another 4.8 percentage points in just seven days. Shares are down 7% over three months and the cost to borrow sits below 2%.

Cerebras Systems is a newer target. Short interest jumped 5.2 percentage points to 20.1% of free float in one week. The AI chip maker only listed recently, and bears are moving fast.

Freddie Mac caught attention after short interest surged 59% in a week to 14.6 million shares, according to ORTEX. A Trump-backed $4.3 billion housing push for Fannie Mae and Freddie Mac landed in the news simultaneously, creating a volatile mix for traders.

Grindr also saw a sharp rise, with SI climbing 4.9 percentage points to 19.4% of free float. Talen Energy moved from 6.2% to 10.8% in seven days, one of the bigger relative jumps in the energy space.

1-800-FLOWERS.COM carries the most extreme setup for a squeeze, with 79.2% short and 25 days to cover. Availability is just 17%, leaving very little room for bears to add.

ORTEX's Index Rebalance Radar flags Corteva deletion odds from MSCI World jumping from 31% to 77% overnight, a move that could force $555 million of selling if confirmed on 11 November.
