ONTO · PEAD ↑ 80

Onto Innovation reported Q2 2026 EPS of $1.93 on 2026-08-06, beating the $1.68 consensus by $0.25 (+14.9%).

Print-day reaction was −2.6% versus the prior close, as the market initially sold into the beat — a modest gap-down open absorbed most of the damage before the session settled. The overnight gap from the T+0 close to the T+1 open surged +11.6%, decisively reversing the print-day softness and signalling strong after-hours conviction in the result. Over the following two trading days the stock drifted an additional +3.7%, sustaining and extending the overnight repricing with no meaningful give-back. Cumulative abnormal return of +15.8% versus SPY.US over the full three-day window firmly places this in PEAD long territory; the documented drift pattern holds through the window ending 2026-11-03.
