Why SMR stock is down today
SMR stock fell 15.67% to $8.61 in the latest session, marking a sharp decline driven by a downgrade from UBS and recent insider selling. The stock's steep drop came amid renewed skepticism about NuScale Power's ability to compete in the nuclear energy sector and concerns over its financial performance.
What Happened
UBS downgraded NuScale Power to Sell, citing a 40% downside potential for the stock. This move followed a broader period of uncertainty for the company, which reported a 74% decline in its stock price over the trailing 12 months. The downgrade added to a growing list of concerns for investors, who have seen the company's fundamentals deteriorate. NuScale is unprofitable with an EPS of -1.54 for the trailing 12 months and has experienced an 81% decline in revenue. The company's CFO, Hamady Robert Ramsey, sold 20,000 shares on August 27, 2026, adding to a series of insider sales totaling $1.0 million in the last 90 days.
What The Data Shows
Over the last 8 trading sessions, the stock has moved minimally, from $8.91 to $8.90, suggesting a lack of directional momentum. The stock has been highly volatile, trading within a 52-week range of $7.21 to $57.42. The recent sharp drop contrasts with a 15% intraday jump reported earlier in the week by Yahoo Finance. The stock's beta of 2.31 indicates it is more volatile than the broader market. The recent insider selling and deteriorating sentiment, with a 7-day average of 46 out of 100, reflect growing unease among stakeholders.
What To Watch
Investors should monitor the company's next earnings report if scheduled, or look for changes in coverage from analysts as the stock remains under pressure.
