Onto Innovation is trading 8.9% down at $236.73 as part of a broad semiconductor decline driven by worries over heavy AI-related capital spending and intensifying competition from Chinese chipmakers.

  • The downward move appears sector-led, coinciding with a sharp decline in the SOXX ETF and a sell-off in Asian chip stocks.
  • There are no company-specific news or fundamental surprises reported for the company today.
