URNM vs S&P 500: Which ETF to Watch
Compare URNM uranium miners ETF vs S&P 500. Analyze performance, risk, fees, and whether URNM fits as a satellite allocation alongside your core holdi...
If you searched for "URNM stock," you found the right comparison, but URNM is not a stock. It is the Sprott Uranium Miners ETF, an exchange-traded fund that holds approximately 35 uranium mining and royalty companies. Comparing it against the S&P 500 means comparing a concentrated sector ETF against the broadest benchmark in U.S. equity markets, and the two instruments work differently at almost every level.
This article covers four dimensions of that comparison: performance history, risk metrics, fee costs, and portfolio fit. The goal is to help investors who already hold a core S&P 500 ETF position decide whether URNM warrants a place on their watchlist as a potential satellite allocation.
Key Takeaways
- URNM is a sector ETF, not a stock. It tracks the North Shore Global Uranium Mining Index and holds uranium miners, royalty companies, and developers at various project stages.
- URNM carries materially higher volatility than the S&P 500, with beta well above 1.0 and historical drawdowns exceeding 50% during uranium bear markets.
- URNM's 0.83% expense ratio is approximately 28x higher than VOO's 0.03%, though fee drag matters less if uranium cycle returns are proportionally larger.
- For investors with an existing S&P 500 core, URNM fits as a satellite allocation, not a core replacement.

What Is URNM? The Sprott Uranium Miners ETF Explained
URNM is the Sprott Uranium Miners ETF, a passively managed sector ETF that holds shares in uranium mining, development, and royalty companies. It does not hold physical uranium, and it is not an individual stock. Trading on NYSE Arca under the ticker URNM, the fund is managed by Sprott Asset Management, a Canadian alternative asset manager specializing in precious metals and real asset investments. As of early 2025, URNM held approximately $1.1 billion in assets under management; verify the current figure at the Sprott Uranium Miners ETF fund page.
The fund tracks the North Shore Global Uranium Mining Index, which includes companies deriving at least 50% of their revenues from uranium mining or royalties. That revenue threshold is what gives URNM its pure-play character: the index excludes diversified mining conglomerates and nuclear utilities, concentrating the fund in businesses whose performance rises and falls with uranium demand and pricing.
Across its portfolio, URNM holds approximately 30–40 positions in uranium producers, explorers, and royalty companies based in Canada, Kazakhstan, the United States, and Australia. Because the fund holds equities of uranium-producing companies rather than the commodity itself, its price behavior tracks uranium spot prices but amplified through company-level operating margins.
The expense ratio is 0.83%, meaning the fund deducts $83 per year from a $10,000 investment. By comparison, VOO deducts $3 per year on the same amount. That $80 annual difference compounds to roughly $920 over 10 years and $2,080 over 20 years at a flat return assumption. Investors should treat that cumulative cost as a drag that requires proportionally superior returns to justify.
URNM vs. URA vs. URNJ: How They Differ
Three uranium ETFs appear frequently in the same searches:
- URNM (Sprott): Pure-play uranium miners and royalty companies, tracking the North Shore Global Uranium Mining Index (approximately 35 holdings). Highest correlation to uranium spot price.
- URA (Global X Uranium ETF): Broader mandate that includes uranium miners plus nuclear utilities and equipment manufacturers. Tracks the Solactive Global Uranium & Nuclear Components Index. More diversified within the nuclear theme but less sensitive to uranium spot price moves.
- URNJ (Sprott Junior Uranium Miners ETF): Focuses on smaller, earlier-stage uranium developers. Higher risk and return potential than URNM, with a smaller-company bias.
URNM is the most concentrated pure-play option among the three.
What Is the S&P 500? Index vs. ETF Distinction
The S&P 500 is a market index, not a purchasable security. Investors gain exposure through ETFs that track it, primarily SPY (SPDR S&P 500 ETF Trust, 0.09% expense ratio), VOO (Vanguard S&P 500 ETF, 0.03%), and IVV (iShares Core S&P 500 ETF, 0.03%). All three track the same index with negligible tracking error; the primary differences are cost and trading volume.
Maintained by S&P Global (formerly Standard & Poor's), the index holds approximately 503 large-cap U.S. companies. It is market-capitalization-weighted, meaning the largest companies by market value (Apple, Microsoft, Nvidia, among others) represent a higher percentage of the index than smaller constituents. Widely regarded as the default benchmark for U.S. equity market performance, the S&P 500 spans all 11 GICS sectors, which is the structural contrast that matters most when comparing it to URNM's single-sector concentration.
For performance comparisons throughout this article, SPY serves as the primary benchmark because of its broad recognition and liquidity. For fee comparisons, VOO is referenced because its 0.03% expense ratio represents the cost floor for S&P 500 access. The S&P 500 index methodology is publicly available for investors who want to review constituent eligibility criteria.
URNM vs S&P 500 Performance History: Returns Compared
URNM and the S&P 500 have delivered sharply different returns over the past five years, driven primarily by uranium commodity cycles rather than broad market conditions. The performance table below presents total return figures for both instruments across standard time horizons.

Short-Term Performance (1-Year Return)
URNM's one-year return fluctuates considerably depending on where uranium spot prices stand in the commodity cycle. In periods of rising uranium prices, URNM has produced one-year returns that far exceed SPY. In periods of falling uranium prices or broad commodity risk-off sentiment, the fund has significantly underperformed. A single-year snapshot is among the least reliable ways to evaluate URNM because it can capture only one phase of a cycle that typically spans 3–7 years.
Long-Term Performance: 3-Year and 5-Year Annualized Returns
Over longer periods, the comparison depends almost entirely on which cycle phase dominates the measurement window. An investor whose 5-year lookback starts in 2019 and ends in 2024 captures URNM's bear market through 2020 followed by its recovery surge in 2021–2022, producing a distinctly different annualized result than someone whose 5-year window starts in 2018 or 2016. Comparing URNM's long-term annualized return against SPY's without understanding the cycle timing is like comparing two sprinters at different points in a race.
Why URNM's Performance Diverges From the S&P 500: The Uranium Cycle
URNM's performance diverges from the S&P 500 because uranium is a commodity subject to multi-year supply-demand cycles that operate independently of broad equity market conditions. Three distinct periods illustrate this pattern:
2016–2019: Uranium bear market. Following the 2011 Fukushima disaster, reactor operators worldwide reduced uranium procurement and several countries accelerated nuclear plant shutdowns. The uranium spot price fell from above $70/lb (U3O8) pre-Fukushima to below $20/lb by 2016. URNM and its predecessor funds trailed the S&P 500 substantially during this period, as miner revenues contracted and development projects stalled.
2021–2022: Spot price recovery and surge. The uranium cycle turned sharply. The launch of the Sprott Physical Uranium Trust in mid-2021 began systematically purchasing physical uranium, tightening spot market supply. A decade of underinvestment had created a structural supply deficit against recovering reactor demand. Uranium spot prices climbed from near $30/lb in early 2021 to above $60/lb by late 2022. URNM significantly outpaced the S&P 500 during this window, with calendar-year returns in some periods exceeding 60%.
2022–2023: Rate-hiking volatility. The Federal Reserve's aggressive rate-hiking cycle pressured growth-oriented assets broadly, and uranium equities were not immune. URNM experienced elevated volatility through this period, with performance decoupling from uranium spot price in some months as macro risk-off sentiment dominated.
The core lesson: URNM's return profile is shaped primarily by the uranium commodity cycle, not by the same macro forces that drive S&P 500 performance. Past uranium cycle behavior does not predict future cycle timing, and uranium bear markets have historically produced drawdowns exceeding 50%.
Risk Comparison: How Does URNM Stack Up Against the S&P 500?
The risk metrics table below quantifies what "riskier than SPY" actually means for URNM. Beta, standard deviation, maximum drawdown, Sharpe ratio, and correlation together give a complete picture that no single metric can provide alone.
| Metric | URNM | SPY (S&P 500) | Time Period | Source |
|---|---|---|---|---|
| Beta (vs. S&P 500) | ~1.80 | 1.0 (by definition) | 3-year | ETF.com / Portfolio Visualizer |
| Annualized Std. Deviation | ~55% | ~16% | 3-year | ETF.com / Morningstar |
| Maximum Drawdown | ~-63% (2022 peak-to-trough) | -33.9% (Feb–Mar 2020) | 5-year | ETF.com / Macroaxis |
| Sharpe Ratio (3Y) | ~0.30 | ~0.75 | 3-year | Morningstar / Portfolio Visualizer |
| Correlation to S&P 500 | ~0.50 | 1.0 | 3-year | Portfolio Visualizer |
All figures are approximate. Verify current values at ETF.com, Morningstar, or Portfolio Visualizer before making investment decisions. Risk metrics change as new data periods are included. Data as of Q1 2025; confirm current figures at source.
Beta measures how much an asset moves relative to the market. A beta of 1.80 means URNM has historically moved approximately 1.80% for every 1% move in the S&P 500. That amplification works both ways. At URNM's approximate beta of 1.80, a 20% SPY decline would historically correspond to roughly a 36% URNM decline under normal correlation conditions. During uranium-specific bear markets, the decline has been steeper and more prolonged.
Return variability, measured by standard deviation, captures how wide the range of actual returns around the average has been. URNM's annualized standard deviation of approximately 55% compares to SPY's 16%, reflecting the amplified swings inherent in a single-commodity sector fund.
Maximum drawdown is the largest peak-to-trough price decline over a specified period, representing the worst-case loss for an investor who entered at the top. URNM's maximum drawdown reached approximately -63% during the 2022 uranium bear market. SPY's comparable figure was approximately -33.9% during the COVID crash of February–March 2020, and approximately -25% during the 2022 rate-hiking bear market.
The worst peak-to-trough decline tells one part of the risk story; the Sharpe ratio tells another by measuring return earned per unit of risk taken. A higher figure means better risk-adjusted performance. URNM's 3-year Sharpe ratio of approximately 0.30 compares unfavorably to SPY's approximately 0.75, reflecting that URNM's elevated volatility has not been consistently compensated by proportionally higher returns across full market cycles. In uranium bull cycles, this relationship can reverse; in bear cycles, URNM's Sharpe ratio deteriorates sharply.
Correlation measures how closely two assets move together. A figure near 0 means the two assets tend to move independently. URNM's correlation to the S&P 500 of approximately 0.50 means the instruments do not move in lockstep, which provides some portfolio diversification benefit when URNM is held alongside an index ETF.
What URNM's Beta Means in Practice Investors considering a $10,000 URNM satellite allocation should stress-test this scenario: if SPY falls 20%, URNM has historically moved approximately -36% under normal correlation conditions, a loss of roughly $3,600 on that position. During uranium-specific downturns, the decline can exceed -60%. Size any satellite allocation with that drawdown tolerance in mind before committing capital.
URNM's Sector Concentration vs. S&P 500 Diversification
URNM concentrates its entire exposure in approximately 35 uranium and nuclear fuel cycle companies. The S&P 500 holds approximately 503 companies across all 11 GICS sectors, including information technology, healthcare, financials, consumer discretionary, industrials, energy, materials, real estate, utilities, consumer staples, and communication services.
This concentration creates idiosyncratic risk: events specific to uranium such as regulatory policy shifts, reactor construction delays, or geopolitical supply disruptions from Kazakhstan or Canada affect URNM with full force while registering as near-zero impact on the S&P 500. The 2011 Fukushima disaster is the clearest historical example; it reshaped global nuclear policy and caused a decade-long uranium bear market, while the S&P 500 recovered relatively quickly from its initial shock.
Concentration is not inherently a flaw. It is the mechanism by which URNM can outperform the S&P 500 substantially during uranium bull cycles. The same concentration that amplifies gains during a uranium price surge amplifies losses during a bear market. Kazatomprom, representing one of URNM's largest holdings and a state-controlled company based in Kazakhstan, adds a specific layer of geopolitical and emerging market risk not present in the S&P 500's primarily U.S.-domiciled holdings.
URNM Top Holdings: What Does This ETF Actually Own?
URNM holds approximately 35 uranium mining and royalty companies globally. The top 10 positions represent the majority of the fund's weight, with concentration in the top five typical of small-sector ETFs.
| Rank | Company | Ticker | Country | Business Type | Approx. Weight | Notes |
|---|---|---|---|---|---|---|
| 1 | Cameco Corporation | CCJ | Canada | Producer | ~17–20% | Largest Western uranium producer; sector bellwether |
| 2 | NexGen Energy | NXE | Canada | Developer | ~8–11% | Rook I project, Athabasca Basin; pre-production stage |
| 3 | Kazatomprom | KAP (LSE GDR) | Kazakhstan | Producer | ~7–10% | World's largest uranium producer. Geopolitical risk: state-controlled entity in Kazakhstan; emerging market concentration exposure not present in S&P 500 |
| 4 | Uranium Energy Corp | UEC | United States | Producer | ~5–8% | In-situ recovery operations; domestic uranium policy beneficiary |
| 5 | Paladin Energy | PDN | Australia | Producer | ~4–6% | Langer Heinrich mine, Namibia |
| 6 | Denison Mines | DNN | Canada | Developer | ~3–5% | Wheeler River project, Athabasca Basin |
| 7 | enCore Energy | EU | United States | Producer | ~3–4% | U.S.-based in-situ recovery |
| 8 | Uranium Royalty Corp | URC | Canada | Royalty | ~2–4% | Royalty model: provides financing to uranium producers in exchange for royalty payments; different risk profile from direct miners |
| 9 | Boss Energy | BOE | Australia | Producer | ~2–4% | Honeymoon project, South Australia |
| 10 | Bannerman Energy | BMN | Australia | Developer | ~2–3% | Etango project, Namibia |
Holdings and weightings are approximate and change with quarterly rebalancing. Verify current holdings at the Sprott Uranium Miners ETF fund page or ETF.com before making investment decisions. Data as of Q1 2025.
The geographic distribution reflects uranium's global supply chain. Canada accounts for the largest share through Cameco, NexGen, Denison, and Uranium Royalty Corp. Kazakhstan follows through Kazatomprom, while the United States contributes through Uranium Energy Corp and enCore Energy. Australian producers and developers round out the remaining weight. This geographic spread means the fund's holdings face different regulatory environments, political climates, and operating cost structures, making its risk profile distinctly different from the predominantly U.S.-domiciled S&P 500.
The business type mix matters for risk calibration. Senior producers like Cameco generate current revenues tied to uranium contracts and spot sales, providing relative stability within the sector. Developers like NexGen Energy (NXE) and Bannerman hold pre-production assets whose value depends almost entirely on future uranium prices and project execution. Uranium Royalty Corp (URC) operates differently from both: the royalty model provides uranium price exposure through payment streams from producing mines rather than direct operating exposure, offering different volatility characteristics.
Kazatomprom deserves specific attention. As the world's largest uranium producer and a state-controlled enterprise headquartered in Kazakhstan, the company introduces a category of risk entirely absent from the S&P 500. Kazakhstan's 2021–2022 civil unrest and subsequent production guidance reductions demonstrated how non-market factors can affect supply and uranium equities held within URNM. Kazatomprom trades as a GDR (Global Depositary Receipt) on the London Stock Exchange under the ticker KAP; it is not listed on major U.S. exchanges.
The Uranium Investment Thesis: Why Investors Are Watching URNM in 2025
Nuclear power plants require uranium fuel to generate electricity. That fact connects a structural shift in global electricity demand to the investment thesis behind URNM. When reactor demand grows, uranium procurement increases, miner revenues expand, and URNM's constituent holdings rise in value. The question for 2025 is whether that demand shift is large enough and durable enough to sustain uranium prices above the levels needed to incentivize new mine development.
Nuclear power has re-emerged as a preferred source of baseload, low-carbon electricity after decades of declining interest. The European energy crisis that began in 2022 pushed multiple governments to reverse or slow nuclear phase-out policies. The United States, France, the United Kingdom, and South Korea each approved nuclear capacity extensions or new reactor construction during this period. The U.S. Prohibiting Russian Uranium Imports Act, signed in 2024, added a supply-side catalyst by restricting Russian enriched uranium imports and creating incentives for domestic and allied-nation uranium production.
On the supply side, the post-Fukushima legacy remains in place. Years of low uranium prices drove mine closures, production cuts, and reduced exploration spending. The resulting structural supply deficit, where current global production capacity falls short of projected reactor demand, forms the medium-term bullish argument for uranium prices (quoted in USD per pound of U3O8, uranium oxide). When uranium spot prices rise, the operating margins of producers like Cameco expand disproportionately, amplifying those moves through the fund's equity holdings.
Small modular reactors (SMRs) are compact, factory-built nuclear reactors under development by companies including NuScale, TerraPower, and X-Energy. Over the coming decade, SMRs are expected to expand nuclear power deployment beyond large-scale plants, adding to long-term uranium fuel demand projections. Deployment timelines remain uncertain, and investors should treat SMR-related demand projections as longer-horizon thesis elements rather than near-term catalysts.
AI, Data Centers, and Nuclear Power: Why Big Tech Is Driving Uranium Demand
The demand chain runs as follows: AI model training and inference require massive, uninterruptible electricity supply; data centers increasingly turn to nuclear power because it provides 24/7 baseload power without carbon emissions; nuclear plants run on uranium. This chain has begun producing concrete commercial agreements.
Microsoft reached a long-term power purchase agreement with Constellation Energy to support the restart of Three Mile Island Unit 1 in Pennsylvania, a facility closed since 2019. Announced in 2023, the agreement was driven by Microsoft's data center electricity requirements. Separately, Google signed a nuclear PPA with Kairos Power in 2024 for an advanced reactor fleet, citing clean, firm power needs for its computing infrastructure. Amazon also committed to multiple nuclear power agreements, including an investment in X-Energy's SMR development program announced in 2023.
These agreements do not guarantee uranium price appreciation, but they represent a qualitatively new demand signal. The world's largest technology companies are signing long-term contracts for nuclear power specifically because conventional renewables cannot meet the scale and reliability requirements of AI infrastructure. Increased nuclear plant utilization and new construction both require uranium fuel, supporting demand for the companies this fund holds.
These are demand catalysts, not guarantees. Uranium is a cyclical commodity, and URNM's performance remains sensitive to shifts in uranium spot price, reactor policy delays, and broader energy market conditions.
Fees and Costs: URNM vs S&P 500 ETF Expense Ratio Comparison
URNM charges 0.83% annually; VOO charges 0.03%. The dollar impact of that differential grows significantly over time.
| Investment Amount | URNM Annual Fee (0.83%) | VOO Annual Fee (0.03%) | 10-Year Fee Drag (URNM vs. VOO) | 20-Year Fee Drag (URNM vs. VOO) |
|---|---|---|---|---|
| $10,000 | $83/year | $3/year | ~$920 cumulative difference | ~$2,080 cumulative difference |
| $50,000 | $415/year | $15/year | ~$4,600 cumulative difference | ~$10,400 cumulative difference |
Figures assume flat 0% return to isolate fee impact. In a positive return environment, fee drag compounds at a higher absolute dollar amount. Source: Fund prospectus data. Verify current expense ratios at Sprott.com (URNM) and Vanguard.com (VOO) before investing.
For context, 0.83% sits within the normal range for specialized sector ETFs. Other sector ETFs charge considerably less: XLE (Energy Select Sector SPDR) charges 0.09%, and XME (SPDR S&P Metals and Mining) charges 0.35%. These are broader exposures with diluted commodity specificity, however. URNM's fee reflects the cost of maintaining a pure-play uranium mandate with a smaller investable universe. Actively managed funds in the alternatives space frequently charge 1.0% or more.
The practical framing is opportunity cost. In a uranium bull cycle where URNM delivers 30–50% annual returns against SPY's 10–15%, the 0.80 percentage point fee differential is immaterial relative to the return gap. In a flat uranium market, that same fee differential erodes roughly 0.80 percentage points of annual return in a portfolio that would otherwise have kept compounding at SPY's lower cost. Investors who hold conviction in a durable uranium cycle have a reasonable case that the fee is justified. Investors who are uncertain about cycle timing face a harder calculation.
Should You Hold URNM Alongside an S&P 500 ETF? Portfolio Framework
URNM and an S&P 500 ETF can coexist in a portfolio. For investors with uranium conviction and appropriate risk tolerance, they serve complementary roles rather than competing ones.
URNM's correlation to the S&P 500 of approximately 0.50, per Portfolio Visualizer data, means the two instruments do not move in lockstep. In periods where uranium equities surge while the broad market is flat or declining, URNM can contribute positive returns that offset S&P 500 underperformance. The reverse holds equally during uranium bear markets. This partial independence is the structural argument for holding both instruments within a core-satellite framework.
The Core-Satellite Strategy: Where URNM Fits
The core-satellite strategy divides a portfolio into a stable core, typically 70–90% in broad-market index ETFs like VOO or SPY, and a smaller satellite sleeve for higher-conviction, higher-risk sector allocations. The core captures broad market returns with low fees and established diversification; the satellite targets thematic upside with proportionally higher risk and closer monitoring requirements.
URNM is a satellite candidate, not a core replacement. Its sector concentration, commodity-cycle dependence, and drawdown history make it unsuitable as the primary foundation of a retail investment portfolio. Within a satellite sleeve, the fund provides direct uranium sector exposure that a VOO or SPY position cannot replicate.
The table below offers an illustrative allocation framework, not a personalized recommendation:
| Investor Profile | Illustrative URNM Allocation | S&P 500 ETF Allocation | Risk Profile Context |
|---|---|---|---|
| Conservative (low uranium conviction) | 0–3% | 80–97% | Low sector risk tolerance; full core focus |
| Moderate (some uranium conviction) | 3–7% | 73–90% | Medium risk tolerance; willing to accept cycle volatility |
| High-Conviction Uranium Bull | 7–10% | 70–83% | High volatility tolerance; multi-year time horizon |
Allocation ranges above are illustrative frameworks for discussion only, not personalized investment recommendations. Appropriate allocations depend on individual financial circumstances, time horizon, risk tolerance, and portfolio context. Consult a qualified financial advisor before making allocation decisions.
Who Should Consider URNM and Who Should Not
URNM fits a specific investor profile. The following criteria distinguish investors for whom URNM warrants consideration from those for whom it does not.
URNM may suit investors who:
- Hold genuine conviction in the uranium demand thesis, specifically that AI-driven power demand, structural supply deficits, and growing nuclear capacity commitments will support sustained uranium price appreciation
- Can tolerate drawdowns of 30–50% or more on the satellite portion of their portfolio without being forced or tempted to sell at the bottom
- Already hold a stable, diversified S&P 500 ETF core and are evaluating URNM as an addition, not a substitution
- Have a multi-year time horizon aligned with the uranium commodity cycle, as uranium bull markets have historically unfolded over 3–5 year periods
URNM is less suited for investors who:
- Require capital preservation or low volatility across all portfolio positions
- Are building their first or primary investment account without an existing diversified core
- Are uncomfortable with material emerging market exposure, specifically Kazatomprom's state-controlled Kazakhstan operations
- Need near-term liquidity or may require access to the capital within 1–2 years
This framework is informational only and does not constitute personalized investment advice. Past performance is not indicative of future results.
URNM vs S&P 500 Verdict: Which Belongs on Your Watchlist?
Both URNM and an S&P 500 ETF belong on a watchlist, but for different reasons and serving different functions in a portfolio.
The S&P 500, accessed through SPY or VOO, is the appropriate core holding for the majority of a retail investor's portfolio. It offers broad diversification across 500 U.S. large-cap companies, 11 GICS sectors, expense ratios as low as 0.03%, and a long track record of compounding returns over time. For most investors, the bulk of their equity allocation belongs here.
URNM belongs on a watchlist as a potential satellite allocation for investors who meet three specific conditions. First: conviction in the uranium demand thesis. The AI data center nuclear contracting activity from Microsoft, Google, and Amazon represents a genuine demand signal, but uranium remains a cyclical commodity and cycle timing is uncertain. Second: tolerance for drawdowns of 30–50% or more on the satellite portion. URNM has experienced peak-to-trough declines exceeding 60% during uranium bear markets, and investors who cannot hold through those periods are likely to exit at the wrong time. Third: a multi-year time horizon. Uranium cycles play out over years rather than quarters, and attempting to time entry and exit around cycle peaks and troughs is a high-difficulty strategy even for experienced commodity investors.
This verdict is not binary. Investors who already hold VOO or SPY as a core position, believe in the nuclear demand thesis, and can accept URNM-level volatility in a 5–10% satellite sleeve have a reasoned case for watching the fund closely. Investors who want broad-market exposure without sector concentration risk, commodity cycle timing, or geopolitical exposure from Kazakhstan will find that VOO or SPY serves their needs on its own.
Investors evaluating these instruments may benefit from adding both tickers to a watchlist and monitoring URNM's performance relative to uranium spot price trends, re-evaluating the satellite allocation decision if fundamental demand catalysts shift materially.

Frequently Asked Questions: URNM vs S&P 500
Is URNM a stock or an ETF?
URNM is the Sprott Uranium Miners ETF, an exchange-traded fund holding approximately 35 uranium mining and royalty company equities. It trades on NYSE Arca like a stock, but it represents a basket of securities rather than a single company. The term "URNM stock" appears in searches because ETFs trade on exchanges, but URNM is legally and functionally an ETF, not an individual stock.
What is URNM's expense ratio compared to SPY?
URNM carries a 0.83% annual expense ratio versus SPY's 0.09%, approximately a 9x differential. On a $10,000 investment, this equals roughly $83 per year for URNM versus approximately $9 for SPY. The gap widens to $83 versus $3 when comparing against VOO (0.03%). This fee differential compounds over multi-year holding periods and is a meaningful factor in long-term net return comparison.
What are URNM's top holdings?
URNM's top holdings include Cameco Corporation (CCJ, Canada's largest uranium producer), NexGen Energy (NXE, developer of the Rook I deposit in Saskatchewan), and Kazatomprom (KAP, the world's largest uranium producer based in Kazakhstan). Cameco typically represents the largest single weight at approximately 17–20%. The full top-10 breakdown with approximate weightings appears in the holdings section above. Current data is available at the Sprott fund fact sheet.
Does URNM pay dividends?
URNM has historically paid minimal or no regular dividends. Uranium mining companies at the development and early production stage generally reinvest cash flow into exploration, mine construction, and balance sheet management rather than distributing income. URNM is a capital appreciation vehicle, not an income investment.
What is the difference between URNM and URA?
URNM (Sprott) holds only uranium miners and royalty companies whose revenues derive primarily from uranium extraction. URA (Global X Uranium ETF) includes uranium miners plus nuclear utilities and nuclear equipment manufacturers such as Constellation Energy. URNM tracks the North Shore Global Uranium Mining Index; URA tracks the Solactive Global Uranium & Nuclear Components Index. URNM is more directly correlated to uranium spot price; URA offers broader nuclear sector exposure with less pure-play uranium sensitivity.
Can URNM replace SPY in a portfolio?
No. URNM concentrates in approximately 35 uranium stocks, carries a beta of approximately 1.80, and has experienced historical drawdowns exceeding 60%. SPY provides exposure to approximately 503 U.S. large-cap companies across all 11 GICS sectors. These instruments serve different structural roles. URNM is a high-conviction sector satellite; SPY is a diversified market core. Using URNM as a portfolio core would eliminate the broad diversification that defines a core holding's function.
How does uranium demand affect URNM's price?
Uranium miner equities amplify movements in the uranium spot price (quoted in USD per pound of U3O8). When uranium prices rise, the profit margins of producers like Cameco expand disproportionately, driving company valuations higher. URNM aggregates approximately 35 such companies, so the fund's price reflects the collective performance of uranium equities rather than the physical commodity directly. The inverse relationship holds during uranium price declines.
Is URNM a good investment in 2025?
URNM warrants consideration for investors with conviction in the uranium demand thesis, specifically AI-driven nuclear power procurement, structural uranium supply deficits, and global nuclear capacity expansion. That thesis may prove durable. The fund also carries volatility of 2–3x the S&P 500 and sector concentration risk that can produce drawdowns exceeding 50%. For investors with a diversified S&P 500 core and a multi-year time horizon, a satellite allocation may be appropriate. This is informational content, not personalized investment advice.
What drives the price of URNM?
URNM's price is driven primarily by uranium spot price movements, which affect the revenues and profit margins of the fund's constituent miners and developers. Secondary factors include nuclear energy policy (reactor approvals, license extensions, phase-out reversals), supply-side dynamics such as Kazatomprom production guidance, and broader commodity market sentiment. Because the fund holds mining equities rather than physical uranium, it amplifies spot price moves rather than tracking them directly.
What is URNM's beta compared to the S&P 500?
URNM's 3-year beta is approximately 1.80 relative to the S&P 500, meaning the fund has historically moved approximately 1.80% for every 1% move in the broader market. A beta of 1.80 indicates URNM amplifies both gains and losses relative to SPY. In practice, uranium-specific events can drive URNM far beyond what beta alone would predict, in both directions.
How has URNM performed compared to the S&P 500 over the last 5 years?
URNM's 5-year performance relative to the S&P 500 depends on where the uranium commodity cycle stands within the measurement window. During the 2021–2022 uranium price surge, URNM significantly outpaced SPY. During the preceding bear market (2016–2020) and during rate-hiking periods, it lagged substantially. Verify current 5-year annualized figures at ETF.com or Morningstar, and read the uranium cycle context in the performance section above before drawing conclusions from a single time-horizon comparison.
What is the Sharpe ratio of URNM compared to SPY?
URNM's 3-year Sharpe ratio is approximately 0.30, compared to SPY's approximately 0.75 over the same period. The Sharpe ratio measures return earned per unit of risk taken, with higher values indicating better risk-adjusted performance. URNM's lower ratio reflects that its elevated volatility has not been consistently compensated by proportionally higher returns across full market cycles. In uranium bull phases, this ratio can improve significantly; in bear phases, it deteriorates sharply.
