Taiwan Semiconductor Manufacturing (TSMC) ADR dropped 9.8% to $357.16 after U.S. midterm elections, as Democratic wins raised regulatory concerns for AI data centers. Analysts warned of potential negative sentiment for AI infrastructure. TSMC faces pressure ahead of its November 10 sales report, needing $53.3B in quarterly revenue to justify its valuation. The selloff affected the broader semiconductor sector, with Micron, AMD, and Nvidia also declining.
