AMD stock declined 4.25% on November 18, 2025, closing at $230.29 as part of a broader AI sector selloff. Momentum indicators have turned bearish, and analysts warn the stock may retest its early-October gap near $200 if selling pressure persists. The decline reflects broader market concerns about AI valuations, with AMD falling 5.6% and dragging down the QQQ index by 1.7%. Despite the recent weakness, analyst sentiment remains constructive with 18 buy ratings and a median price target of $280, suggesting potential recovery if market sentiment stabilizes.
