PWR · PEAD ↑ 100

Quanta Services reported Q3 2026 EPS of $5.71 on 2026-10-29, beating the $4.68 consensus by $1.03 (+22.0%).

Print-day reaction was +4.7% versus the prior close, as the stock surged from $606.89 to $635.18 on a beat of more than 22% against consensus. The overnight gap to the T+1 open reversed sharply, pulling back -4.3%, signalling meaningful after-hours profit-taking following the initial spike. Over the subsequent two trading sessions the stock drifted +5.8%, fully absorbing the overnight fade and extending well above the print-day close. Cumulative abnormal return of +10.6% versus SPY.US — which declined -2.3% over the same window — places this firmly in PEAD long territory; the documented drift pattern holds through 2027-01-26.
