AMD is trading at 6% down now at $218.83 after a confluence of negative catalysts specific to the semiconductor sector and broader market weakness. The primary company-specific driver is President Donald Trump’s threat to impose 'massive' new tariffs on Chinese goods, which directly impacts chipmakers reliant on global supply chains and access to Chinese markets[1]. Compounding this, the U.S. Senate passed a bill to limit AI chip exports to China, creating uncertainty for AMD’s growth prospects in a key market[2]. Chinese authorities have reportedly responded with tighter export controls on rare earth metals—critical for chip production—and increased scrutiny of semiconductor shipments, further pressuring the sector[1]. These developments have triggered a broad sell-off in tech and semiconductor stocks, with the NASDAQ down 2.61% and the S&P 500 down 2.06%, amplifying AMD’s decline[1]. While AMD remains up significantly year-to-date, today’s drop reflects acute sensitivity to geopolitical and regulatory risks in the semiconductor industry[1][2].
