If you’re checking your portfolio at the end of December and you’re invested in advanced nuclear, the view can look ugly. The industry, a darling of the 2025 market, is currently flashing red warnings to end the year.
Oklo Inc. (NYSE: OKLO) has slid 36% in the past three months. NuScale Power Corporation (NYSE: SMR) has taken an even steeper hit, down nearly 62% in the same period. For investors who bought into the nuclear renaissance narrative earlier this year, these declines might feel like a signal to exit.
