CME · PEAD ↑ 63

CME Group reported Q3 2026 EPS of $3.02 on 2026-10-21 (before the open), beating the $2.98 consensus by $0.04 (+1.3%).

Print-day reaction was a muted +0.16% versus the prior close, as the modest beat offered little immediate price discovery. The overnight gap into T+1 open was a more meaningful +1.17%, signalling that the market revised its view upward after hours. From T+1 through T+3 the stock continued to drift higher by +0.68%, sustaining rather than fading the gap. Cumulative abnormal return of +4.80% against SPY.US — which fell 0.48% over the same window — places this squarely in PEAD long territory; the documented pattern holds through the window ending 2027-01-18.
