Taiwan Semiconductor Manufacturing Company (TSMC) experienced a significant selloff after a two-day trading break caused by a typhoon. When trading resumed, TSMC shares fell by 6.5% in Taipei. The decline is attributed to global investors' growing skepticism about the promises of artificial intelligence (AI), which has affected the broader tech sector. The Taiwan stock market closure meant that investors could not trade TSMC's local shares ($2330.tt), leading to increased selling pressure on TSMC's American Depositary Receipts (ADRs). This situation has contributed to TSMC joining the global tech rout, impacting companies like $NVDA, $ARM, $AMD, $INTC, $AVGO, $MRVL, $MU, and $SMCI.
