What Is NUKZ? Range Nuclear Renaissance Index ETF

NUKZ is the Range Nuclear Renaissance Index ETF, a pure-play nuclear energy fund that launched in January 2024. It tracks the Range Nuclear Renaissance Index, a basket designed to capture the full nuclear value chain rather than any single slice of it.

That means NUKZ holds advanced and small-modular reactor developers, utilities that operate nuclear plants, engineering and construction firms, and uranium miners and fuel suppliers, roughly 45 to 50 names in all. The expense ratio is 0.85%, and the fund has attracted strong interest as investors look for clean, reliable power sources to feed AI data centers and electrification.

NUKZ's portfolio spans several corners of the nuclear ecosystem. Recent top holdings have included Cameco (uranium mining), GE Vernova and Rolls-Royce (reactors and power equipment), Samsung C&T (construction), Talen Energy, Vistra, and Constellation Energy (nuclear utilities), plus small-modular-reactor developers like NuScale Power and Oklo.

By sector the fund leans toward industrials and utilities, with energy and basic materials filling out the rest. This mix is what separates NUKZ from uranium-only funds: it captures reactor builders and power producers, not just the commodity that fuels them.

The best-known nuclear-adjacent ETFs are the Global X Uranium ETF (URA) and the Sprott Uranium Miners ETF (URNM). Both concentrate on uranium miners and physical uranium, so they are effectively bets on the uranium price and mining equities.

NUKZ is broader. It holds miners but also reactor developers, utilities, and services firms, making it a whole-ecosystem nuclear play. Investors who want direct uranium-price sensitivity may prefer URA or URNM, while those who want exposure to the entire nuclear buildout, including SMR developers and power producers, may prefer NUKZ.

NUKZ launched into a wave of enthusiasm for nuclear power. The thesis is straightforward: electricity demand from AI data centers, electrification, and reshoring is rising fast, and nuclear offers clean, always-on baseload generation that renewables alone cannot match.

Because the fund is young and concentrated, its performance has been volatile and closely tied to sentiment around nuclear policy, power deals with tech companies, and progress on new reactors. It has not yet been tested through a full market cycle, so its long-term risk and return profile remains uncertain.

NUKZ is a single-theme, single-sector fund, which makes it inherently riskier than a diversified index fund. It holds early-stage reactor developers such as NuScale Power and Oklo that may have little or no current earnings, and their prices can swing sharply on news, funding, and regulatory milestones.

The fund is also sensitive to the uranium price through its mining holdings and to interest rates through its utility holdings. A shift in nuclear policy, a stalled reactor project, or a change in AI-driven power forecasts could move the whole portfolio at once. Investors typically use funds like this as a small satellite position rather than a core holding.

NUKZ may fit investors who are specifically bullish on nuclear power as a clean baseload energy source and want diversified exposure across the value chain rather than a bet on any one company. Given its concentration, short history, and 0.85% fee, it is generally treated as a satellite thematic holding, not a core position.

NUKZ trades on the NYSE and can be purchased through any major brokerage, including Robinhood, Fidelity, Schwab, and Public. Many of these platforms support fractional shares, so you can invest a set dollar amount even if a single share is expensive.

To see how NUKZ fits your broader strategy, you can connect your existing brokerage account to Walnut. Walnut lets you hold NUKZ inside a thematic nuclear or energy basket, track it against target weights, and analyze it alongside your other positions, while trades continue to execute at your own broker.

ETFs are passive bundles; thematic baskets in Walnut let you concentrate within them. If you hold NUKZ as a core position, these are the themes you might layer on as satellites.

NUKZ is a satellite, thematic holding for investors bullish on nuclear power as a clean baseload source for AI and electrification. It is broader than uranium-miner funds because it also holds reactor builders and utilities, but at 0.85% it is not cheap and it is concentrated in a single, volatile theme.

Whether NUKZ is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, concentration, and what would have to be true for it to outperform from here in is NUKZ a buy?
