AMD shares were selling off during the regular session as the semiconductor sector experienced a broad retreat. While the stock had initially surged 5.9% on November 12 following a Bank of America price target hike to $700 and a William Blair upgrade, investor sentiment shifted on November 13 as the market reevaluated the AI trade in the wake of Nvidia CEO Jensen Huang's resignation. Although AMD was initially viewed as a primary beneficiary of Nvidia's leadership crisis, the broader chip sector ultimately succumbed to uncertainty regarding the future of the AI boom and industry-wide risks.
