ONTO

In the past six months, Onto Innovation's stock (ONTO) has experienced notable volatility, reaching an all-time high of $386.46 on June 29, 2026. Over the last year, the stock price increased by 105.17% to 115.03%, with a year-to-date return of 67.59% as of September 18, 2026, though it decreased by 15.75% in the month prior. This volatility is attributed to the cyclical nature of the semiconductor equipment industry and strong AI-driven demand for advanced packaging and process control tools. Key events include the Q2 2026 earnings report on August 6, 2026, where Onto Innovation reported EPS of $1.93, beating estimates, and revenue of $343.1 million, up 35.3% year-over-year, leading to a sharp rise in shares due to strong performance, a record backlog, and upbeat Q3 guidance. Bullish analyst commentary, highlighting strong demand for the new Dragonfly G5 process control platform and projecting significant annual revenue growth and margin expansion, along with an alliance with Rigaku, has framed Onto Innovation as an undervalued AI-driven process control play. However, the stock has also seen declines alongside broader weakness in semiconductor equipment stocks due to investors digesting stretched valuations, concerns about an AI slowdown, and rising bond yields, impacting ONTO's price despite strong results.
