Nuclear energy has come roaring back as countries and corporations seek reliable, low-carbon power options.
The AI explosion and the data centers required are a big part of nuclear energy renaissance.
Top nuclear energy stocks right now include BWX Technologies, Denison Mines and NANO Nuclear Energy.
Nuclear energy is stepping back into the spotlight as governments and corporations look for reliable, low-carbon power that can run around the clock. From life-extending existing reactors to backing next-generation technologies like small modular reactors (SMRs), policy support is strengthening across the globe. For investors, that creates opportunities spanning established utilities, advanced reactor developers, and specialized nuclear technology firms.
Is Now a Good Time to Invest in Nuclear Energy Stocks?
Several signals suggest the industry may be at an inflection point. Countries are approving new reactor projects, extending operating licenses, and committing capital to SMR commercialization to support grid stability and decarbonization goals. At the same time, power-hungry customers such as AI data centers and large industrial users are locking in long-term nuclear supply contracts, improving visibility into future cash flows.
That said, nuclear investing rewards patience. Long development timelines, regulatory complexity, and project-execution risks mean results can vary widely from company to company.
Below, we analyze and rank the best nuclear stocks using a blend of Zacks Rank signals, Style Scores, and fundamentals to highlight compelling opportunities today. (To see a full list of nuclear energy stocks, visit our Nuclear Energy thematic stock screen).
This is our short term rating system that serves as a timeliness indicator for stocks over the next 1 to 3 months. How good is it? See rankings and related performance below.
The Zacks Industry Rank assigns a rating to each of the 265 X (Expanded) Industries based on their average Zacks Rank.
An industry with a larger percentage of Zacks Rank #1's and #2's will have a better average Zacks Rank than one with a larger percentage of Zacks Rank #4's and #5's.
The industry with the best average Zacks Rank would be considered the top industry (1 out of 265), which would place it in the top 1% of Zacks Ranked Industries. The industry with the worst average Zacks Rank (265 out of 265) would place in the bottom 1%.
The Zacks Sector Rank assigns a rating to each of the 16 Sectors based on their average Zacks Rank.
A sector with a larger percentage of Zacks Rank #1's and #2's will have a better average Zacks Rank than one with a larger percentage of Zacks Rank #4's and #5's.
The sector with the best average Zacks Rank would be considered the top sector (1 out of 16), which would place it in the top 1% of Zacks Ranked Sectors. The sector with the worst average Zacks Rank (16 out of 16) would place in the bottom 1%.
The Style Scores are a complementary set of indicators to use alongside the Zacks Rank. It allows the user to better focus on the stocks that are the best fit for his or her personal trading style.
The scores are based on the trading styles of Value, Growth, and Momentum. There's also a VGM Score ('V' for Value, 'G' for Growth and 'M' for Momentum), which combines the weighted average of the individual style scores into one score.
Value ScoreA
Growth ScoreA
Momentum ScoreA
VGM ScoreA
Within each Score, stocks are graded into five groups: A, B, C, D and F. As you might remember from your school days, an A, is better than a B; a B is better than a C; a C is better than a D; and a D is better than an F.
As an investor, you want to buy stocks with the highest probability of success. That means you want to buy stocks with a Zacks Rank #1 or #2, Strong Buy or Buy, which also has a Score of an A or a B in your personal trading style.
Zacks Earnings ESP (Expected Surprise Prediction) looks to find companies that have recently seen positive earnings estimate revision activity. The idea is that more recent information is, generally speaking, more accurate and can be a better predictor of the future, which can give investors an advantage in earnings season.
The technique has proven to be very useful for finding positive surprises. In fact, when combining a Zacks Rank #3 or better and a positive Earnings ESP, stocks produced a positive surprise 70% of the time, while they also saw 28.3% annual returns on average, according to our 10 year backtest.
BWX Technologies is a specialized nuclear solutions provider serving defense, clean energy and medical markets. The company reported a $7.3 billion backlog at the end of 2025, offering strong revenue visibility. Its leadership in naval nuclear propulsion, sole-source positioning on key programs and expansion into microreactors and radiopharmaceuticals position it to benefit from long-term nuclear demand and global decarbonization trends.
Potential Risks
Performance remains sensitive to federal funding uncertainty, contract execution risks and regulatory requirements, while delays in approvals, project awards or backlog conversion could impact growth visibility and near-term earnings.
Forecast
A Zacks Rank #1 (Strong Buy) with Style Scores of F for Value, B for Growth and C for Momentum points to improving expectations rather than a bargain setup. The Price, Consensus & EPS Surprise chart shows a clear uptrend, mostly green surprises, and upward-tilting 2026–2027 estimate lines, suggesting revisions remain supportive.
