AMKR · PEAD ↓ 80

Amkor Technology reported Q2 2026 EPS of $0.70 on 2026-07-27, beating the $0.47 consensus by $0.23 (+48.9%).

Print-day reaction was -6.5% versus the prior close, a steep sell-the-news move despite the EPS beat, closing at $60.71 against $64.96 the session before. The overnight gap to the T+1 open deepened the damage by a further -14.7%, signalling aggressive after-hours and pre-market selling with no recovery bid. Over the following two trading days the price continued lower before a partial recovery, producing a Day 1–3 drift of +5.6% — a bounce that only partially offset the gap-down damage. Cumulative abnormal return of -26.1% versus SPY.US firmly places this in PEAD short territory; per the documented drift pattern, the holding window runs through 2026-10-22.
