SEMI.AS is trading at $19.01, down 4.09%, as hotter-than-expected September inflation revived concerns about higher rates and borrowing costs.

  • September CPI was 3.7% year over year, versus 3.6% expected.
  • Chip stocks remained under pressure as investors questioned debt-heavy AI infrastructure spending; the semiconductor index fell 0.88% on October 15, even as broader U.S. indexes recovered.
  • TSMC also declined despite record profits, reflecting sector-wide risk aversion rather than company-specific weakness.
