NuScale Power in 2026: When to Buy and When to Sell Your Position

As 2026 unfolds, small modular reactor developer NuScale Power (NYSE: SMR) finds itself at a critical crossroads. The company’s stock price has declined roughly 20% since the start of the year, following a remarkable 200% surge throughout 2025. For investors evaluating whether to buy and sell positions in this emerging energy company, the decision hinges on risk tolerance, investment timeline, and confidence in breakthrough nuclear technology.

The Case Against Buying Now: Why Conservative Investors Should Wait

NuScale Power remains a pre-revenue enterprise operating in the nuclear energy sector, still pursuing its first commercial sale. While small modular reactor technology represents a promising innovation in clean energy, the company’s manufacturing capabilities and reactor designs remain unproven in real-world deployment. Until a customer materializes and places a binding order, it’s difficult to gauge the true market potential.

For risk-averse investors, caution is warranted. The prudent approach involves waiting for concrete evidence of commercial traction—ideally a confirmed purchase agreement followed by the delivery of the first operational reactor. Such milestones would validate both the technology and the business model before committing capital. Jumping in prematurely exposes conservative portfolios to significant downside if the company fails to secure customers or faces technical setbacks.

The Upside for Early Risk-Takers: Two Major Opportunities on the Horizon

Conversely, aggressive investors willing to accept higher risk may find NuScale Power compelling. The company is pursuing two substantial sales opportunities that could reshape its financial trajectory. Discussions with a Romanian energy utility and ongoing negotiations with the Tennessee Valley Authority and ENTRA1 Energy represent potential game-changers. While neither has culminated in a sale announcement, the proximity of these opportunities creates asymmetric upside potential.

The 2025 performance demonstrates how swiftly NuScale’s stock could respond to positive catalysts. A confirmed sale announcement could trigger another significant rally, rewarding early-stage investors handsomely. However, it’s crucial to recognize that NuScale functions as an industrial manufacturing enterprise. Its value proposition extends far beyond a single transaction—the long-term opportunity lies in establishing a factory-based production model for modular reactors. Early entry positions investors to capture gains from multiple future sales and market expansion.

Understanding the Risk-Reward Calculus: When to Hold or Exit

Investors who purchased NuScale near its 2025 highs are nursing considerable losses. This situation presents two strategic options. First, these positions could be strategically liquidated to harvest tax losses that offset gains elsewhere in a portfolio. Second, if you lack conviction in the company’s reactor technology or commercial prospects, exiting makes financial sense regardless of whether it locks in losses.

The core investment thesis ultimately rests on technological viability. NuScale’s reactors must prove capable of supporting a sustainable, profitable manufacturing and deployment business. Without this foundation, holding the stock or initiating new positions becomes difficult to justify. Conversely, investors genuinely convinced the technology will transform the energy landscape should consider whether their conviction matches their risk capacity.

The Technology Factor: Where the Real Investment Story Lies

Beyond quarterly earnings or near-term sales announcements, NuScale’s fundamental value proposition centers on whether its small modular reactor design can compete economically against traditional and renewable energy sources. This isn’t a short-term trading opportunity but rather a long-term thesis about the future of nuclear power generation.

The Motley Fool Stock Advisor research team regularly identifies promising growth companies, yet NuScale failed to make their latest list of top-rated picks. Interestingly, when Netflix appeared on their recommendation list in December 2004, a $1,000 investment would have grown to $415,256 by 2026. Similarly, early Nvidia backers (April 2005) would have seen $1,000 appreciate to $1,133,904. These historical examples underscore how breakthrough technology companies can deliver exceptional returns—but only for investors with both foresight and patience to endure volatility.

Your decision to buy and sell NuScale Power shares should align with your belief in the company’s technological trajectory and your ability to withstand price fluctuations. For most investors, monitoring developments in their sales pipeline and waiting for customer confirmations represents the prudent middle ground between blind optimism and complete dismissal of a potentially transformative energy technology.
