AMD stock drops 8% as chip-sector selloff deepens
The move
AMD shares fell 8.1% to $507.93 on Oct. 22, part of a broader tech selloff after chipmaking-equipment supplier Lam Research warned on Oct. 21 that supply-chain constraints were limiting its own revenue guidance, and as oil prices jumped on renewed Middle East conflict.
Why it matters
The drop shows how exposed AI-chip stocks are to supply-chain and macro shocks even when the companies' own results are strong.
The bear case
AMD's business hasn't changed; one bad trading day in a volatile sector doesn't reflect the company's actual AI chip demand.
What to watch
AMD's next earnings report, expected in early November 2026.
