AMGN · PEAD ↑ 79

Amgen reported Q2 2026 EPS of $6.29 on 2026-08-04 (after market close), beating the $5.60 consensus by $0.69 (+12.3%).

Print-day reaction was +2.9% versus the prior close, as AMGN moved from $378.87 to $390.02 on the earnings session. The overnight gap to the T+1 open added another +0.9%, with no after-hours fade into the next morning's open at $393.36. Over the subsequent two trading days, the stock drifted an additional +0.8%, closing at $410.95 on 2026-08-07 — a continuation rather than a reversal of the initial move. Cumulative abnormal return of +6.4% versus SPY.US over the three-day window places this firmly in PEAD long territory; the documented drift pattern holds through the window end of 2026-10-30.
