On September 1, Onto Innovation Inc. fell 5.07% in regular trading, trading at $253.575/share, with turnover of $28.63 million, as the semiconductor equipment sector continued to face broad-based selling pressure.

The semiconductor equipment sector has been hit by persistent selloffs in recent sessions. Last Friday, peers including Entegris fell 7.2%, Amkor dropped 6.8%, and FormFactor declined 6.5%, while Onto Innovation Inc. itself closed down 7.46%. The weakness carried into today's session, with Applied Materials down 3.98%, Lam Research down 3.66%, KLA Corporation down 3.99%, and AXT Inc plunging 9.11%, reflecting widespread pressure across the sector.

Valuation concerns have further intensified the pullback. Analysts had previously estimated the intrinsic value of Onto Innovation Inc. at approximately $226.96, suggesting the stock had been trading at a premium of roughly 28.5% relative to that estimate, adding to downside risk as the sector correction deepened.
