REGN · PEAD ↑ 16

Regeneron reported Q2 2026 EPS of $12.53 on 2026-07-30, beating the $8.00 consensus by $4.53 (+56.6%).

Print-day reaction was +6.2%, with shares closing at $738.34 versus the prior close of $695.42 — a sharp gap up on the earnings beat. The overnight session gave back ground, with the T+1 open at $726.69 representing a -1.6% gap down from the T+0 close. Over the subsequent two trading days (T+1 close through T+3 close) the stock drifted -0.3%, a modest fade that largely preserved the initial pop. Cumulative abnormal return of +3.6% versus SPY.US clears the PEAD long threshold; the documented drift pattern holds through the window ending 2026-10-27, though conviction registers at a low 16.
