    ASML Falls 6% on Reports of Chinese DUV Breakthrough

    Question

    ASML Falls 6% on Reports of Chinese DUV Breakthrough

    Direct answer

    ASML shares faced pressure as reports emerged that China has successfully manufactured its own deep-ultraviolet (DUV) lithography machines. While this represents a technological milestone for China's self-sufficiency goals, the scale remains small compared to ASML's output. Analysts suggest the market reaction may be overdone given ASML's dominant position in extreme-ultraviolet (EUV) technology, which China still cannot replicate.
