Why is Advanced Micro Devices stock surging today?

Advanced Micro Devices (AMD) stock is surging today, up 8.4% in morning trading and reaching a new 52-week high of $609.75. This rally is being driven by optimism ahead of the Trump-Xi summit on September 24, as AI semiconductor stocks lead a broad market rally. The PHLX Semiconductor Index climbed over 2% in morning trading, with the rally linked to the expectation that AI industry leaders will attend a White House dinner during the high-stakes U.S.-China meeting.

Positive preliminary talks between U.S. Treasury Secretary Scott Bessent and Chinese Vice Premier He Lifeng have also contributed to the rally, with investors focusing on potential outcomes related to tariff policies, trade limitations, and technology regulations. AMD currently has strong analyst support, with 55 analysts covering the stock, 39 of them recommending buys, and a mean price target of $617, 10% above the stock's previous close.

The NASDAQ Composite is up 1.2%, the S&P 500 is up 0.7%, and falling crude oil prices and easing Treasury yields have reinforced the risk-on tone in the market.
