Why Is ASML Holding NV (ASML) Stock Price Down 5.80% Today, July 27? China DUV Competition Fears Hit Chip Equipment

ASML sold off after reports of Chinese progress in domestic deep-ultraviolet lithography revived long-term competitive-risk concerns, compressing the premium investors assign to ASML's equipment franchise. The move was reinforced by a broad semiconductor hardware drawdown, suggesting de-risking across chip-equipment exposures rather than a company-specific earnings or guidance reset. Near-term focus shifts to whether the sector stabilizes and whether the China DUV narrative gains confirmation.
