On September 4, Onto Innovation Inc. rose 5.31% in regular trading, trading at 265.46 USD/share, with turnover of $23.07 million. The rally was driven by a broad-based rebound across the semiconductor equipment sector following sustained selling pressure earlier in the week.

On September 1, the semiconductor equipment sector experienced widespread declines, with Onto Innovation Inc. falling over 5% intraday while peers including Applied Materials, Lam Research, KLA Corporation, and AXT Inc all posted significant losses. That selloff followed a prior session where Entegris dropped 7.2%, Amkor fell 6.8%, and FormFactor declined 6.5%. Valuation concerns also weighed on sentiment, with analysts previously estimating Onto Innovation Inc. intrinsic value at approximately $226.96, implying a roughly 28.5% premium over that level.

Today's move carries a corrective nature. Within the Semiconductor Equipment sector, KLA Corporation rose 6.04%, AXT Inc gained 5.6%, Lam Research advanced 4.54%, Applied Materials climbed 4.35%, and ASML Holding rose 3.84%, reflecting strong sector-wide recovery momentum.
