ONTO is trading at $342.99 (+6.44%) in pre-market as investors buy the dip in semiconductor and AI-related stocks following the June 23 tech selloff.

  • The move aligns with broader market sentiment, with the Nasdaq rising 2.24% in early trading.
  • No company-specific catalyst was identified; the price action is attributed to sector-wide relief buying across the AI chip industry rather than a fresh announcement from ONTO.
