Quanta Services Inc. (PWR) closed at $642.33 on October 1, 2026, a decline of 1.51% over the prior 24 hours. The drop trimmed recent gains but left the stock in positive territory across longer timeframes.
Over the past seven days, PWR is up 1.14%, and over the past 30 days the stock has gained 5.84%. Those figures suggest the single-session pullback occurred within a broader period of steady appreciation for the infrastructure services company.
Quanta Services carries a market capitalization of $97.99 billion, reflecting its standing as one of the larger companies in its sector. The stock's 30-day advance of 5.84% represents a meaningful move in absolute terms for a company of that size.
Thursday's session resulted in a modest retreat, but the weekly and monthly data indicate that PWR has maintained an upward trajectory over the recent period leading into October 2026.
