HOUSTON—Move over, Palantir and Uber. The S&P 500’s top-performing, large cap stock in 2025 is the redundantly named NRG Energy.
A growing power generator and retail electric business, NRG’s energized stock has surged by 75% this year, and by about 240% since chairman Larry Coben also took over as interim president and CEO in November 2023 amid an activist push from billionaire Paul Singer’s Elliott Investment Management.
