The nuclear energy sector has shown a clear internal divergence in this wave: the trends of mature operators and early-stage small nuclear companies are diametrically opposite.

Constellation Energy and Centrus Energy rose by nearly 2% and 1.2% respectively, both having actual operating assets and stable cash flows as the basis for valuation—Constellation is the largest nuclear power operator in the United States, and the demand for uninterrupted clean power from AI data centers directly benefits its long-term contract pricing; Centrus is the only enterprise in the U.S. with uranium enrichment capabilities, and its strategic value is clear under the policy backdrop.

Cameco fell slightly by about 2%, as phased pressure on uranium prices dragged down the underlying stock.

Nano Nuclear Energy plunged over 7%, and Lightbridge fell over 4.8%. Both are in the technology R&D stage, far from commercial deployment. In a window of generally weak market risk appetite, such high-valuation early-stage targets are more susceptible to selling.

Overall, the long-term logic of nuclear energy remains intact, but within the sector, it is necessary to distinguish between operating assets and concept valuation types of targets.
