AMD Shares Drop 8% Amid China’s New Chipmaking Technology Announcement
Advanced Micro Devices Inc (NASDAQ: AMD) fell over 8% following an announcement by a Shanghai-based firm that it had developed domestic immersion DUV lithography systems. The development, reported on July 27, 2026, raised concerns about the potential disruption of ASML’s long-standing dominance in chipmaking equipment and triggered broader semiconductor market volatility. Despite strong fundamentals—including Q1 earnings per share of $1.37 (beating estimates) and data-center revenue growth to $5.8 billion—AMD's stock was heavily impacted by investor fears, even though the new Chinese technology does not threaten TSMC’s EUV-based production or AMD’s advanced accelerator roadmap. The real concern appears tied more to valuation than technical risk: AMD trades at a forward P/E of 60 and an EV/EBITDA in the upper 80s—well above industry averages. The stock is vulnerable during market shocks due to its high multiples, not because of any fundamental weakness.
