Onto Innovation is trading at $280.00 (+4.29%) in pre-market after a two-day rebound. No fresh company-specific headline, earnings update, or analyst action was identified; the move appears tied mainly to stronger semiconductor sentiment.
The chip sector is rising in pre-market trading, with SOXX up 3.10%, as tech leadership and broader risk-on flows support semis. Onto Innovation also rebounded on August 3 despite weaker sector tape, suggesting the current move extends that recovery.
