After suffering its steepest annual decline since 2023, NuScale Power (NYSE: SMR) is testing the patience of investors who once rode one of the most dramatic small modular reactor recoveries on record.
The stock has shed more than half its value through 2026, a collapse that mirrors the kind of drawdown the company’s shareholders endured three years earlier.
What makes that comparison striking is what followed the 2023 decline: NuScale shares more than quintupled the subsequent year, delivering extraordinary gains to those who held through the pain.
That precedent is now the central question hanging over the battered reactor developer, as analysts and retail investors alike debate whether a repeat of that trajectory is plausible.
Small modular reactor companies occupy a uniquely volatile corner of the energy market, where long development timelines, regulatory complexity, and shifting government policy can swing sentiment dramatically in either direction.
NuScale has been among the most visible players in the SMR space, attracting attention from investors drawn to the promise of next-generation nuclear power as an alternative to fossil fuels and intermittent renewables.
The company’s roller-coaster stock history reflects a broader pattern in early-stage energy technology, where commercial milestones and contract news tend to drive outsized moves in either direction.
A decline exceeding 50 percent in a single calendar year is severe by any measure, and it raises legitimate questions about whether the business fundamentals justify a recovery of the magnitude seen after 2023.
For investors who were present during the post-2023 rally, the memory of that quintupling creates a powerful psychological anchor, even if the circumstances driving any future recovery would necessarily differ.
The nuclear energy sector broadly has attracted renewed interest from governments and corporations seeking reliable, low-carbon baseload power, a trend that could provide a supportive backdrop for SMR developers willing to wait out the volatility.
Whether NuScale can translate that broader interest into the kind of concrete commercial progress that once sent its shares surging remains the defining challenge for the company and its long-suffering shareholders.
History in speculative sectors rarely repeats precisely, but for a stock that has already demonstrated the capacity to move more than 400 percent in a single year, the possibility is difficult to dismiss entirely.
