Onto Innovation is trading 4.47% up at $280 in pre-market, with Asian semiconductor strength potentially supporting the move despite no clear company-specific announcement on September 8, 2026.

  • Strong second-quarter results, raised second-half revenue expectations, and the completed $720 million Rigaku investment are recent bullish developments but predate this move.
  • Broader U.S. futures are mixed-to-lower.
