AMD's -17.3% single-day plunge to $200.19 following Q4 earnings represents an extreme overreaction given the company beat estimates with $1.53 EPS on $10.27B revenue and data center grew 39% YoY to $5.4B. The selloff was driven by Q1 guidance of $9.8B versus inflated expectations exceeding $10B, but the fundamental AI infrastructure thesis remains intact with the OpenAI partnership, MI455X launch in H2 2026, and strategic positioning as Nvidia's primary alternative. At $200, the stock has surrendered all 2026 gains and offers a compelling risk-reward for a 2-3 month recovery toward $240-250 as sentiment normalizes.
