Why Is NUSCALE PWR CORP A (SMR) Stock Down Today?

NuScale Power stock fell by 6.04% in the session to $7.54, marking a significant decline for the small modular reactor developer. The drop came amid a broader market shift in nuclear energy stocks, as recent regulatory developments and market dynamics reshaped investor sentiment. While some SMR peers saw gains earlier in the week, NuScale's stock has struggled to maintain momentum, particularly as regulatory approvals have favored competitors and broader sector optimism has waned.

What Happened

NuScale Power’s stock declined sharply as the market digested mixed signals from the nuclear energy sector. A recent regulatory approval for a small modular reactor was announced, but it was not for NuScale’s design, highlighting the competitive landscape the company faces. While some SMR producers like Oklo and X-Energy saw early gains, NuScale’s stock reversed course. The session opened with a -1.1% gap down from the previous close and continued to fall throughout the morning, reaching a low of $7.49 before stabilizing slightly. The stock closed at $7.54, with a volume of 4.7 million shares, significantly below its 3-month average.

What The Data Shows

NuScale’s fundamentals remain challenging, with a trailing twelve-month revenue decline of 81% and an unprofitable EPS of -1.54. The stock has traded between $7.21 and $57.42 over the past 52 weeks and has seen seven fresh 52-week lows on October 7. Recent insider transactions also suggest caution, with six sell transactions totaling $981K reported in the last 90 days, including two by the CFO. Options activity showed a notable put premium of $146K, indicating bearish positioning. The stock has also declined by 4.4% over the last eight sessions, from $8.39 to $8.02.

What To Watch

NuScale Power is scheduled to report third quarter 2026 results on November 5, 2026, with a conference call and webcast available. Investors will be watching for signs of progress in the company’s construction plans and how it differentiates its technology in the competitive SMR market.
