Advanced Micro Devices shares rose as much as 10% on Monday, lifting the chipmaker above a $1 trillion market capitalization for the first time during a five-session rally driven by renewed demand for AI chips. The stock has nearly tripled this year, while its year-to-date performance gap over Nvidia has exceeded 160 percentage points. U.S. stocks extended their advance on expectations for sustained AI-related corporate investment and resilient earnings, but rising Treasury yields challenged risk appetite after strong business activity and accelerating input costs heightened inflation concerns. The 10-year Treasury yield surged past 5.22% intraday, a fresh 19-year high, while the 30-year yield climbed to 5.53%, its highest since 2004. Meta, Moderna and Akamai also posted sharp gains, while Planet Fitness and Gen Digital fell amid concerns that AI agents could make subscription cancellations easier. Micron is due to report fourth-quarter results after Wednesday's close. The broader market backdrop includes MSX's listing of RWA tokens linked to major U.S. stocks and exchange-traded funds.
