ASML Holding is trading 4.19% down at €1,464.20 on October 16, following the broad semiconductor selloff on October 15. - Reuters reported ASML shares fell 5% Thursday amid investor concerns over AI investment financing costs, data-centre constraints and high expectations for 2028–2029. - Strong results and outlook did not offset the pressure; the move appears sector-driven, not tied to a fresh company-specific negative catalyst. - Broader technology weakness was reported amid inflation and interest-rate concerns; no volume or activity data were supplied.
