ASML's selloff on China's mass production of DUV machines is a huge overreaction that double counts ASML's own guidance. Export controls made Chinese indigenization inevitable, with SMIC trialling domestic tools since Q3'25, and ASML's China share of sales was already falling from ~50% in 2024 to 33% in 2025 and ~20% guided for 2026. ASML is richly valued, but the stock held up after earnings that showed the same China decline. x.com x.com x.com
