Public Service Enterprise Group is trading 18.6% higher at $79.12 after hours, with no confirmed company-specific explanation. - The price compares with its September 28 regular-session close of $66.72; the after-hours move is unusually large. - The company’s latest prominent updates concern storm-related outage restoration, not a major financial or corporate announcement. - Broader markets were weak September 28 amid rising oil prices, Treasury yields and geopolitical concerns; those factors do not explain the sharply opposite move.
