U.S. Chip Stocks Slide as China Reportedly Begins Mass Production of Homegrown DUV Lithography Machines

The development fueled concerns that China is accelerating its semiconductor self-sufficiency efforts, pressuring major chipmakers such as Nvidia, ASML, Micron, and Sandisk while dragging the broader S&P 500 lower.
