Advanced Micro Devices (AMD) has been one of the top performers in the S&P 500 ($SPX) during the first half of 2026. Specifically, AMD stock has surged 142% year-to-date (YTD), outperforming Nvidia (NVDA) stock's gain of just over 4% over the same period.
The rally has been driven by AMD's solid financial performance over the past several quarters, led by its growing share in the artificial intelligence (AI) infrastructure space. Demand for its Instinct GPU accelerators remains solid, driven by a diversified customer base and ongoing AI infrastructure spending.
