ChipMOS Technologies is trading 10.04% up at $60.62, with the move aligning with a broad semiconductor rally rather than a new company-specific announcement on September 18, 2026.

  • The semiconductor ETF is up about 2.78%, supported by renewed AI optimism and positive industry developments.
  • ChipMOS Technologies’ latest notable update was September 10 revenue growth of 33.3% year over year, but that release predates today’s move.
