On November 6, 2026, TSMC shares fell to the 10% daily trading limit before closing down 4.69%. The sell-off in semiconductor stocks spread from Wall Street to Asian markets amid fears of a slowdown in the AI sector.
Taiwan’s Taiex recorded its fourth-largest single-day point loss. The government authorized the National Financial Stabilization Fund to intervene and buy shares to support the market.
Retail interest in TSMC surged, with odd-lot trading more than doubling as small investors bought the dip. Separately, a report said TSMC is considering producing advanced memory chips at Nvidia’s request, potentially deepening its role in the AI supply chain.
