VST is trading at $168.65 (up 3.6%), extending its strong June rally. - The momentum is fueled by Vistra's strategic position in AI-related power, notably its role as preferred power provider for the KKR-backed Helix Digital Infrastructure platform, announced June 11. - Recent analyst upgrades from firms like Bernstein and Seaport Global, along with positive commentary on its utility fundamentals, have further bolstered investor confidence. - This price action reflects continued sector optimism rather than a specific new catalyst today.
