NuScale Power shares climbed as much as 15.4% to $11.37 on Tuesday, September 8, before closing near $11.19, as a broad rally in nuclear and small modular reactor stocks lifted trading activity. About 53.6 million shares changed hands, 74% above typical volume, while Oklo gained nearly 5% and Nano Nuclear Energy rose about 9.2%. The advance was not tied to a company announcement or rating change and came as the broader market declined. NuScale had recently traded near its July 2026 52-week low of $7.21, while its approximately $1.89 billion cash and liquid-investment position and debt-free balance sheet contrasted with quarterly revenue of just $0.07 million, down 99.1% from a year earlier. Wall Street's consensus rating remains Hold, with an average target of $13.50. Earlier interest in NuScale's manufacturing, artificial intelligence and reactor-control initiatives, along with expectations for AI data-center power demand and political support for advanced nuclear energy, helped sustain sector attention, but those developments were not identified as the cause of Tuesday's move.
