COHR · PEAD ↑ 68

Coherent reported Q1 FY2027 EPS of $1.80 on 2026-11-04 (after market close), matching the $1.80 consensus exactly — a 0% beat/miss.

Print-day reaction was −6.0% versus the prior close, as the stock sold off sharply despite an in-line EPS print. The overnight gap to T+1 open extended the damage a further −5.4%, signalling that after-hours sentiment remained distinctly negative. Over the following two trading sessions (T+1 close through T+3 close), however, the stock staged a sharp reversal, drifting +32.7% — decisively unwinding the initial sell-off. Cumulative abnormal return of +8.8% versus SPY.US puts this firmly in PEAD long territory; drift sharply reversed the initial reaction, and the holding window runs through 2027-02-01.
