ASML Holding is trading 3.7% down at $11.71, with semiconductor-sector pressure the clearest explanation. - Semiconductor stocks sold off after investors reacted to Lam Research’s cautious outlook and renewed concerns about returns on AI infrastructure spending. - Higher oil prices amid Middle East tensions contributed to a broader risk-off mood that weighed on technology shares. - Search results identified no new ASML-specific event explaining the decline; recent positive earnings and demand news do not clearly explain this session’s drop.
