Taiwan's weighted index closed down 3.2% at 41,574.72, its lowest level in over three months, dragged by losses among major chipmakers. Democrats' strong showing in the US midterms increased uncertainty over AI regulation, prompting investor concern that near-term AI-related capex could be affected and that tech profit forecasts may be overly optimistic, BNP Paribas analyst William Bratton said.
