AMD shares fall roughly 8% in October 22 chip sell-off

AMD stock dropped sharply on Thursday, October 22, 2026, closing near $508 after a risk-off session in semiconductors. Coverage attributes the move mainly to renewed worries about semiconductor supply chains and softness in PC demand, which drew attention away from the company's long-term AI data center growth. The decline ran ahead of a broader technology sector drop and a roughly 1% fall in the S&P 500. Analyst commentary that followed in the same coverage is not reproduced here.
