DSY.PA · PEAD ↑ 100

Dassault Systèmes reported Q2 2026 EPS of €0.31 on 2026-07-23, beating the €0.30 consensus by €0.01 (+3.3%).

Print-day reaction was +3.7% versus the prior close, a clean gap-and-hold off the earnings print. The overnight move into T+1 open added a further +0.5%, with no after-hours fade suggesting institutional accumulation rather than fast-money cover. Day 1-through-3 drift then extended a striking +5.7%, well clear of the initial reaction in magnitude and showing no sign of mean-reversion. Cumulative abnormal return of +19.2% versus SPY.US — which lost 0.9% over the same window — places this decisively in PEAD long territory; the holding window runs through 2026-10-20.
