Uranium ETF Concentration Puts Cameco, Constellation and PSEG at the Top of the Trade
The fund's top three holdings now carry nearly a quarter of assets, leaving the ETF exposed to utility and miner moves alike.
The top three positions in this nuclear-focused exchange-traded fund are Cameco at 8.20%, Constellation Energy at 7.79% and Public Service Enterprise Group at 7.56%, putting a uranium miner and two regulated utilities side by side at the head of the book4. That trio accounts for roughly 23.5% of the fund, a concentration level that turns a thematic allocation into a bet on three discrete balance sheets.
The mix is unusual for a nuclear trade. Cameco gives direct exposure to uranium mining economics, where spot price moves feed straight into earnings expectations4. Constellation and PSEG are utilities whose nuclear fleets are already built and whose shares trade on power prices, regulated returns and fuel costs rather than on exploration results. Holding them in the same top-three bucket means the fund is not a pure uranium play, and the split shows up in performance.
Over the past week the concentrated miner-heavy product, URNM, climbed about 8%, and it is still up about 20% over the past 12 months4. That is a sharp reversal from a fund that is down about 10% from early January and slightly negative year-to-date, while URA is roughly flat for the year4. The swings matter for anyone sizing positions: a 40% monthly gain in Uranium Energy stock and a 21% gain in NuScale Power stock have both turned into sharp down days with no fundamental trigger, according to one review of the price action5. When money crowds into a theme in weeks, it can exit the same way.
The utility weighting changes the character of the drawdown. NLR's year-to-date decline of about 6% is milder than the miner drawdowns, and its one-year return of about 2% is more subdued in both directions4. Its dividend yield of 2.7% sits well above those of URA or URNM, a function of the utility-heavy composition4. For income-oriented holders, that yield is the compensation for giving up the miner beta. For traders, it is a drag when uranium spot runs.
Beneath the fund flows, the demand story that drew capital into these names has not reversed. Thirty-eight countries have pledged to triple nuclear capacity by 2050, Meta has signed agreements for up to 6.6 GWe of nuclear, and the US Department of Energy is offering support, according to a June review of the sector2. Small modular reactors are pitched as 24/7 baseload with greater placement flexibility and fewer location constraints than conventional plants1. The gap between that buildout and the fuel to run it is where the bull case lives.
On the supply side, utilities are short billions of pounds of uranium they have not yet bought, a gap one September analysis described as getting harder to ignore6. That framing supports the miners in the top of the book. It does less for the utilities, which face the same procurement math as a cost line rather than a revenue opportunity.
The Saudi angle adds a slower-burning variable. On July 22, President Donald Trump announced a deal to allow Saudi Arabia to enrich uranium for civilian nuclear power, though Congress has not approved it and critics argue it carries proliferation risk given the kingdom's rivalry with Iran3. Approval would widen the addressable market for enrichment and fuel fabrication over years, not quarters, and the legislative path is unresolved.
Cameco's own numbers show the tension between narrative and reported results. Total revenue of $3.6 billion marked a decline of 8%, and its energy solutions division saw a year-over-year sales decline, yet profitability in that business rose from $47 million to $74 million1. The company also carries an orders backlog of $25.7 billion1. Shares were up more than 18% this year as of May 26, 20261. A shrinking top line with a large backlog is a timing story, and the market has been willing to pay for the timing.
The trade implication is a barbell that is not actually a barbell. Buyers of the fund get miner leverage and utility defensiveness in one wrapper, which smooths the ride but caps the upside when spot uranium moves hard. The expense ratio of 0.75% is slightly above URA's, so the smoothing is not free4.
What to watch is the next contract cycle and whether utilities convert their uncovered requirements into term purchases. Until they do, the miner holdings carry the thesis and the utility holdings carry the yield, and the fund's top three positions will keep trading on two different sets of drivers.
