COHU · PEAD → 8

Cohu reported Q3 2026 EPS of $0.36 on 2026-10-28, beating the $0.23 consensus by $0.13 (+56.5%).

Print-day reaction was +4.2% versus the prior close, as the stock responded decisively to the sizeable EPS beat. The overnight gap into T+1 was flat at 0.0%, indicating the after-hours session added no incremental directional pressure. Over the following two trading sessions the stock shed -9.4%, fully reversing the initial pop and then some. Cumulative abnormal return of -2.8% versus SPY.US lands just inside the neutral band, yielding a PEAD verdict of none with minimal conviction; drift contested rather than confirmed the initial reaction, and the hold window runs through 2027-01-25.
