Why Taiwan Semiconductor Manufacturing (TSM) Stock Is Down Today

Investivoq PriceTracker

Taiwan Semiconductor Manufacturing (TSM) is down 3.5% today. Here is some analysis on what might have caused this price movement.

Analysis: The decline appears to be more about market reaction than a fundamental miss. TSMC released strong September and third-quarter revenue figures, but the lack of fresh guidance, a slight month-over-month sales dip, and a broader tech selloff likely sparked profit-taking.

Details:

  • TSMC said September 2026 revenue was about NT$511.86 billion, up 54.6% from a year earlier but down 0.6% from August.
  • The company’s third-quarter revenue reached roughly NT$1.49 trillion, above its prior quarterly outlook and ahead of market expectations.
  • TSMC is scheduled to hold its third-quarter earnings conference on October 15, which means investors may be waiting for updated margin, demand, and capital spending commentary before adding exposure.
  • Risk appetite across technology weakened as Treasury yields stayed near multi-year highs and oil prices jumped, creating added pressure on semiconductor shares even where business momentum remained strong.
