Onto Innovation is trading at $255.79, up 4.76% in pre-market on September 16, 2026, amid a rebound in semiconductor-equipment shares.

  • Rebounding after consecutive declines, including an 11.07% drop on September 14.
  • No fresh company-specific announcement or earnings release was identified overnight; available coverage attributes the move to sector-wide de-risking rather than a new Onto Innovation catalyst.
  • Broader futures are modestly higher before the Federal Reserve decision, but the market backdrop alone is insufficient to confirm causation.
