Vistra Corp (NYSE: VST) stock price plummeted 12.6% on Friday, closing at $146.02, as AI-related power stocks broadly declined. This widespread dip, affecting companies like Constellation Energy, Talen Energy, and NRG Energy, was influenced by an overall tough day on Wall Street, with the S&P 500 experiencing its weakest finish in six months, and utilities taking a significant hit. Despite Vistra’s recent rating upgrade to investment grade and its strong position in the AI-fueled data center demand, broader market anxieties over inflation, interest rate hikes, and rising power-purchase agreement costs contributed to the sell-off.
