ASML Holding is trading 6.9% down at €1455.80 as investors react to reports that a state-backed Chinese firm has mass-produced advanced chipmaking equipment.
- The breakthrough potentially erodes the effectiveness of Western export controls and intensifies direct competition for ASML's specialized machinery.
- The decline coincides with a broader sell-off in the semiconductor sector, driven by profit-taking following an extended AI-led rally.
- Market sentiment is further pressured by growing concerns over rich valuations across the global chip industry.
