Shares of NANO Nuclear Energy (NASDAQ:NNE) are down 10% midday Thursday, trading near $26. Oklo (NYSE:OKLO | OKLO Price Prediction) stock is off about 8%, while Cameco (NYSE:CCJ) is slipping 4%.
The pullback follows a powerful rally for the nuclear trade. NANO Nuclear had ripped 35% over the past month, while Oklo had surged 63% in a month. Cameco rallied a steadier 12% on the month.
Today’s red looks more like profit-taking than a thesis change. All three names remain positive year to date (YTD), with NNE stock up 9%, OKLO stock up 2%, and CCJ shares up 30%. Some observers might even claim that a cooling-off was overdue.
Profit-Taking Caps a Hot Streak
NANO Nuclear’s run was supercharged by a strategic partnership with Super Micro Computer to integrate advanced nuclear energy with AI servers, announced earlier this week. Super Micro Computer (NASDAQ:SMCI) tie-ins have become a fast lane to retail attention, and NNE shares responded with the kind of vertical move that almost always invites a fade.
Oklo’s catalyst was more concrete. The Nuclear Regulatory Commission approved the Principal Design Criteria Topical Report for the Aurora powerhouse on Wednesday, a milestone retail investors immediately seized on. Reddit sentiment for Oklo has held in bullish territory with sentiment scores between 66 and 70 even as today’s selling kicked in, a sign that long-term holders aren’t blinking.
Cameco’s bid came from Wall Street rather than a filing. Scotiabank lifted its price target to $175, citing Western world decarbonization, energy independence, and power security demand. With 9 strong-buy and 11 buy ratings against just 3 holds, sentiment around the uranium giant remains decisively skewed bullish.
AI Power Demand Keeps the Long-Term Story Intact
The structural backdrop for these names hasn’t changed. Major tech hyperscalers have signaled growing appetite for nuclear baseload to feed AI data centers, and the U.S. policy environment, including the ADVANCE Act and NRC fee reductions, is moving to support faster reactor deployment. That demand engine is what investors are paying for in Oklo and NANO Nuclear today, and it’s the same trend supporting a host of best nuclear energy stocks for the AI power boom.
Cameco sits on the supply side of the same story. The company is the largest publicly traded pure-play uranium producer in the Western world and holds an ownership stake in Westinghouse Electric, which puts it at the center of any global reactor build-out. The trailing valuation looks rich at a P/E ratio of 113x, yet analysts still see upside to a $139 average price target.
The advanced reactor names trade differently. Oklo remains pre-revenue, posting a FY24 net loss of $73.62M with its first Aurora powerhouse deployment targeted for late 2027 to early 2028 at Idaho National Laboratory. NANO Nuclear is similarly milestone-driven, which is why both stocks tend to move on news rather than on fundamentals.
What to Watch From Here
For Oklo stock, the next major share-price move could depend on follow-through licensing milestones and any expansion of its roughly 14 GW customer pipeline. Watch for whether OKLO stock holds above its pre-rally base if today’s profit-taking deepens into the afternoon.
NANO Nuclear’s price action will hinge on whether the Super Micro Computer partnership translates into firm commercial milestones. Momentum traders who chased the move higher are the most likely sellers if NNE stock breaks technical levels into the close, and $26 is a level to track.
Cameco is the calmest of the three for a reason. With quarterly earnings growth of 88% last reported and a market position that benefits regardless of which advanced reactor design wins, CCJ shares may keep drawing buyers on dips.
Today’s pullback across NANO Nuclear, Oklo, and Cameco shares looks like consolidation rather than collapse. The nuclear-AI thesis remains intact, but the magnitude of the recent rally raised the bar for further near-term upside. Prudent investors weighing exposure here should expect more volatility, particularly in the milestone-driven advanced reactor names, and may consider waiting for the dust to settle before adding new risk.
