Advanced Micro Devices surged about 10% on 16 June 2025, making it the best-performing stock in the S&P 500. The rally came two trading days after the company’s AI-focused product showcase and followed a series of upbeat research notes that predicted a near-term “snapback” in the chipmaker’s performance. Enthusiasm for artificial-intelligence hardware lifted other large technology names. Microsoft touched an intraday record near $500 as traders executed roughly $40 million of bullish call-option trades, while Nvidia moved closer to its own peak after six brokerages lifted their June price targets by roughly 20%. The moves underscore brisk investor demand for companies seen as central to the fast-growing AI ecosystem.
