KLA is trading at $178.10, down 3.21%, as hotter-than-expected September CPI lifted Treasury yields and rate-hike concerns.

  • September CPI showed 3.7% annual inflation, versus 3.6% expected.
  • Reuters reported U.S. chip stocks remained under pressure; KLA’s decline extends a semiconductor-equipment selloff linked to China competition concerns.
  • Available reporting describes sector-wide pressure, not a new KLA-specific announcement; no trading-volume figure was provided.
