Bears Pile Into Wolfspeed and Cerebras

Short sellers moved aggressively into two names this week. Wolfspeed now sits at 113% SI % FF. That is up 15 points in just seven days.

The beleaguered chipmaker has faced mounting losses and debt concerns. Bears keep adding. The stock remains one of the most heavily shorted in the US market.

AI chip upstart Cerebras Systems also drew fresh shorts. Its SI % FF rose 6.6 points to 38%. Cerebras went public in late 2025. Bears appear skeptical of its valuation amid intense AI chip competition from Nvidia and Broadcom.

Broadcom unveiled a new "Jalapeño" AI inference chip with OpenAI this week. Broadcom's own SI % FF sits at just 1.2%. Short sellers have largely avoided mega-cap AI plays.

Lucid Group carries 34% SI % FF. That barely budged this week. The EV maker's stock dipped Wednesday as bulls and bears remain locked in a standoff.

On the covering side, Salesforce saw the biggest short squeeze signal. Bears cut 2.1 points off SI % FF. EchoStar also saw covering of 3.3 points. Both names may have attracted buyers on recent dips.

GameStop remains at 13.5% SI % FF. Shorts are not running yet.
