On August 18, Onto Innovation Inc. fell 5.52% in regular trading, trading at $324.97/share, with turnover of $39.77 million. The semiconductor equipment sector faced broad-based selling pressure, dragging down the stock alongside major industry peers.

Within the Semiconductor Equipment sector, Applied Materials fell 5.54%, ASML Holding declined 4.48%, Lam Research dropped 6.14%, AXT Inc lost 6.31%, and KLA Corporation slid 3.81%. The sector-wide weakness weighed heavily on Onto Innovation, which had risen 5.24% the prior session after Goldman Sachs initiated coverage with a Buy rating and a $400 price target. The pullback erased much of that gain despite strong fundamental support, including Q2 adjusted EPS of $1.93, up 54.4% year-over-year and well above the consensus estimate of $1.68, on revenue of $343 million that beat expectations by 5.5%.
