Advanced Micro Devices (AMD) has experienced an extraordinary rally in 2026, with its stock surging over 180% year to date. The rally was driven by recognition of AMD's products being used by major AI hyperscalers like OpenAI and Meta Platforms, rather than new sales. However, as 2026 draws to a close, investors are looking ahead to 2027, and historical trends suggest AMD's stock may face challenges.
AMD's valuation has reached unsustainable levels, with a forward price-to-earnings ratio of over 85, making it one of the most expensive stocks in the market. This valuation is significantly higher than its peers, such as Nvidia (NVDA), which trades at 26 times forward earnings, and Broadcom (AVGO), at 32 times. The market's premium on AMD reflects investor fatigue with Nvidia and a search for alternatives, but this rally may not be sustainable.
The stock's recent gains were fueled by the deployment of AMD's chips in major AI projects, but this growth was already priced in before 2026. The value of new deals may also be baked into the current stock price, which could lead to struggles in 2027. Historical data shows that highly valued stocks either tumble to a reasonable valuation or remain flat as the business grows into its valuation, neither of which bodes well for shareholders.
Investors are advised to consider other AI stocks for 2027, as AMD's future returns may be limited by its lofty valuation. The Motley Fool Stock Advisor team, for instance, did not include AMD in their top 10 stocks for 2027, suggesting a preference for other opportunities in the market.
