Why Did NuScale Stock Drop 14.7% This Week?

NuScale Power (NYSE: SMR) shares declined 14.7% this week, underperforming broader market gains, as investor enthusiasm for nuclear energy stocks linked to artificial intelligence (AI) energy demand cooled. This shift was primarily driven by a Chinese research paper suggesting AI models could be significantly more energy-efficient and comments from a major turbine producer CEO implying potential growth moderation. Despite NuScale's regulatory approval for its reactor design, the company's minimal revenue and substantial ongoing costs, alongside recent downgrades from two investment banks, contributed to the re-evaluation of its previously high valuation.

Analysis

NuScale Power (SMR) shares experienced a significant decline of 14.7% this week, sharply underperforming the S&P 500's 1.9% gain and Nasdaq-100's 2.2% gain. This downturn follows a year-to-date surge of 110% for SMR, driven by expectations of high energy demand from AI data centers. The market's "strongly negative" sentiment reflects a re-evaluation of nuclear energy stock valuations.

The cooling investor enthusiasm was primarily triggered by two key developments. A Chinese research paper suggested AI models could achieve greater energy efficiency without performance sacrifice, directly challenging the premise of insatiable AI energy demand. Additionally, comments from a major gas and wind turbine producer's CEO hinted at a potential tapering of growth in the energy sector, further dampening outlooks.

Despite NuScale's unique regulatory advantage, being the only small modular reactor with full NRC approval, the company faces fundamental challenges including minimal revenue and significant ongoing costs. These concerns, coupled with the broader market re-assessment, led two investment banks to downgrade SMR to "sell" and "underperform" this week. Analysts specifically cited the stock's high valuation as a deterrent for investment at current prices.

Key Decisions for Investors

• Investors should reassess their exposure to nuclear energy stocks, particularly those with high valuations like NuScale Power (SMR), given new data suggesting potentially lower AI energy demand.
• Monitor NuScale's fundamental progress, specifically revenue generation and cost management, as regulatory approval alone does not justify current valuations amidst analyst downgrades.
• Consider waiting for a more attractive entry point for SMR, as suggested by analysts, given the recent 14.7% weekly decline and the "strongly negative" sentiment indicating further potential downside.
