S&P 500 vs Euro Stoxx 50 is a choice between large US companies and a narrower portfolio of eurozone businesses. An S&P 500 UCITS ETF fits a deliberate allocation to US equities. A Euro Stoxx 50 ETF is the more direct tool when you want to increase your exposure to large eurozone companies.
For a first long-term portfolio, there is another question to answer: do you want to choose regional weights yourself, or would a broader global fund better match your needs?
Neither index provides complete world-market coverage. Combining them still leaves markets such as Japan, the UK, Switzerland and emerging economies outside your direct equity allocation.
Quick answer: S&P 500 or Euro Stoxx 50?
| Your objective | Starting point to examine | Main issue to check |
|---|---|---|
| Invest specifically in large US companies | S&P 500 UCITS ETF | Company concentration and unhedged dollar exposure |
| Increase exposure to large eurozone companies | Euro Stoxx 50 ETF | Narrow company and geographic coverage |
| Build one broadly diversified equity holding | Global UCITS ETF | Which countries and company sizes it includes |
| Reduce USD/EUR currency effects on a US allocation | EUR-hedged S&P 500 ETF | Hedging policy and total costs |
| Keep money available for a near-term expense | Neither equity index | Capital stability and access to cash |
Living in Europe does not make Euro Stoxx 50 the automatic choice. Nor does buying an S&P 500 ETF through a euro trading line remove its dollar exposure.

What do the two indices actually own?
The S&P 500 represents the large-cap segment of the US equity market. It is weighted by float-adjusted market capitalisation, so the largest companies have a much greater influence on the index than the smallest constituents. S&P Dow Jones Indices
The Euro Stoxx 50 contains 50 large companies from the eurozone and is also weighted by free-float market capitalisation. The word euro is important: this is not an index of the whole European continent. STOXX index description
| Feature | S&P 500 | Euro Stoxx 50 |
|---|---|---|
| Main market | United States | Eurozone |
| Number of companies | 500 | 50 |
| Weighting | Float-adjusted market capitalisation | Free-float market capitalisation |
| UK and Switzerland included as home markets? | No | No |
| Broad small-cap exposure? | No | No |
| Complete global portfolio? | No | No |
The difference in company count is large, but diversification is not simply a matter of counting holdings. In both indices, a relatively small group of the largest companies can account for a substantial part of performance.
Euro Stoxx 50 also has meaningful technology exposure. The STOXX factsheet consulted for this guide showed banks at 19.7%, industrial goods and services at 17.4%, and technology at 15.8%. These are a snapshot, not fixed allocations. STOXX factsheet
Switching between the indices changes the companies, sectors and valuations you own. The currency difference is only one part of that decision.
S&P 500 vs Euro Stoxx 50 returns: use the same currency
A US ETF gaining 15% in dollars has not necessarily earned 15% for an investor who measures wealth in euros.
A useful comparison needs identical dates, the same reporting currency and consistent treatment of dividends. It should also compare equivalent measures: fund total returns against fund total returns, for example, rather than a fund with reinvested income against a headline price index.
The two accumulating iShares funds below illustrate how much the currency adjustment can matter.
| Calendar year | iShares Core S&P 500: published USD return | S&P 500 fund: approximate EUR return¹ | iShares Core Euro Stoxx 50: published EUR return |
|---|---|---|---|
| 2024 | +24.7% | +32.6% | +11.5% |
| 2025 | +17.6% | +4.0% | +21.8% |
Fund sources: iShares Core S&P 500 UCITS ETF and iShares Core EURO STOXX 50 UCITS ETF.
¹Finorum calculation using rounded published USD fund returns and ECB year-end exchange rates: USD 1.1050 per euro at the end of 2023, 1.0389 at the end of 2024 and 1.1750 at the end of 2025. Sources: ECB 2024 annual accounts and ECB 2025 annual accounts.
The conversion uses:
EUR return = (1 + USD return) × (starting USD-per-EUR rate ÷ ending USD-per-EUR rate) − 1
For 2025, that gives:
1.176 × (1.0389 ÷ 1.1750) − 1 ≈ 4.0%
The underlying figures are fund NAV total returns, reflecting fund expenses, before personal taxes and dealing costs. The calculated euro returns are approximate because the published inputs are rounded and ECB reference-rate timing can differ from fund valuation timing.
In 2024, currency movements increased the S&P 500 fund’s result for a euro investor. In 2025, they worked heavily in the other direction.
Two years do not establish which market will perform better over the next decade. They demonstrate why comparing dollar and euro returns without adjusting the currency can give the wrong impression.
Past performance does not predict future returns.
What currency exposure can do to €10,000
The same relationship can be expressed using the change in the dollar’s value:
EUR return = (1 + USD investment return) × (1 + change in the euro value of the dollar) − 1
Suppose an unhedged US investment gains 10% in dollar terms.
| USD investment return | Change in dollar value measured in EUR | Result in EUR | €10,000 becomes |
|---|---|---|---|
| +10% | −10% | −1% | €9,900 |
| +10% | 0% | +10% | €11,000 |
| +10% | +10% | +21% | €12,100 |
Hypothetical illustrations before fees and taxes, with no contributions or withdrawals. These are not forecasts.
A 10% investment gain and a 10% currency decline do not cancel: 1.10 × 0.90 = 0.99. The investment ends 1% below its starting value in euros.
Here, the currency change means how many euros one dollar is worth. It is not the percentage change in the inverse quotation—how many dollars one euro buys.
A euro trading line is not currency hedging
An ETF can involve several different currency labels.
| Currency label | What it means |
|---|---|
| Trading currency | The currency used to buy and sell that exchange listing |
| Share-class or fund currency | The currency used for accounting or reporting |
| Hedging currency | The target currency against which the strategy seeks to reduce exchange-rate exposure |
State Street’s accumulating S&P 500 UCITS ETF, for example, has a USD share-class currency but listings traded in EUR, GBP, USD and other currencies. Buying its EUR listing does not make it EUR-hedged. State Street fund information
When comparing a hedged vs unhedged S&P 500 ETF, check the exact share class and its documentation. Hedging seeks to reduce specified currency effects; it does not protect you against falling share prices.
Euro Stoxx 50 companies are not economically isolated from currencies either. Their international revenues and costs can expose their profits to exchange-rate movements, even when their shares are priced in euros.
Four UCITS ETFs to compare
Choose the exposure first, then compare products that deliver it.
| Fund and share class | ISIN | Annual TER / ongoing charge | Income treatment |
|---|---|---|---|
| State Street SPDR S&P 500 UCITS ETF (Acc) | IE000XZSV718 | 0.03% | Accumulating |
| iShares Core S&P 500 UCITS ETF USD (Acc) | IE00B5BMR087 | 0.07% | Accumulating |
| iShares Core EURO STOXX 50 UCITS ETF EUR (Acc) | IE00B53L3W79 | 0.10% | Accumulating |
| Xtrackers Euro Stoxx 50 UCITS ETF 1D | LU0274211217 | 0.09% | Distributing |
Sources: State Street, iShares S&P 500, iShares Euro Stoxx 50 and DWS product information.
Selected examples, not an exhaustive ranking. Charges were checked for this guide; confirm current documents and availability through your broker.
Use the ISIN, not only the ticker, to identify the share class. A single share class can have several exchange listings, while similar product names can refer to accumulating, distributing or hedged versions.
Put the fee difference into euros
For a constant €10,000 holding:
| Annual charge | Approximate annual expense represented by that charge |
|---|---|
| 0.03% | €3 |
| 0.07% | €7 |
| 0.09% | €9 |
| 0.10% | €10 |
These expenses are reflected in the fund’s value rather than billed separately. Actual amounts change with the investment’s value, and TER does not capture every cost of ownership.
The difference between 0.03% and 0.10% is approximately €7 a year on €10,000. Selecting a different index to save that amount changes the geographic and sector composition of the entire investment. Compare costs after deciding which exposure belongs in your portfolio.
Broker charges can be more significant for small purchases. A hypothetical €2 dealing fee on a €100 monthly order consumes 2% immediately.
Check commissions, bid–ask spreads, currency-conversion charges, recurring-investment fees and tracking performance alongside TER. Finorum’s guide to UCITS ETFs in Europe explains the broader selection process.
What happens if you own both?
Combining an S&P 500 ETF and a Euro Stoxx 50 ETF lets you choose the regional weights yourself.
A hypothetical €10,000 portfolio split 70/30 contains €7,000 in large US companies and €3,000 in large eurozone companies. That can be an intentional allocation, but it still excludes direct holdings across other major markets and much of the smaller-company universe.
The split also moves over time. If the US holding grows faster, its weight rises above 70%. Selling to restore the target can create dealing costs and taxable gains. Using new contributions to buy the underweight holding can reduce the need for sales.
If you already own a broad global ETF, examine overlap before adding either fund. An additional regional ETF can increase exposure to companies already in your portfolio.
A useful test is to finish this sentence: “I am adding this fund because I want my portfolio to have more…” If you cannot identify the intended exposure, the extra holding may add complexity without meeting a clear objective.
See Finorum’s global vs European ETFs comparison for the broader allocation question.
Tax rules can matter more than the index name
Your tax residence, account type and fund classification help determine your personal tax treatment. The headquarters of the underlying companies do not settle the question.
These examples reflect rules checked in September 2026 and should be reviewed before a 2027 transaction.
Germany: accumulating funds can still create current tax
Germany’s investment-fund regime includes the Vorabpauschale, which can create taxable income without a cash distribution. The calculation is subject to statutory limits and annual parameters. Section 18 of the Investment Tax Act
Qualifying equity funds also benefit from a 30% partial exemption for private investment income under the relevant rules. Section 20 of the Investment Tax Act
Check the exact fund classification and your broker’s tax handling. Buying a eurozone ETF instead of an S&P 500 ETF does not by itself make German investment taxation simpler.
France: establish PEA eligibility first
If you invest through a Plan d’épargne en actions (PEA), confirm that the exact ETF qualifies before comparing small differences in annual charges.
Qualifying withdrawals after the PEA’s five-year period benefit from income-tax exemption on gains, while social contributions remain payable. The relevant period relates to the plan, not five years of ownership of each individual ETF. French tax authority: PEA withdrawals
Do not assume every European equity ETF qualifies. The State Street S&P 500 share class listed above, for example, is explicitly marked not PEA eligible in its product information.
Spain: account for the tax cost of switching
Spain’s traspasos regime can defer taxation on qualifying transfers between certain investment funds. ETFs generally do not receive the same treatment. The exclusion extends to equivalent foreign-listed products, with transitional provisions for certain holdings acquired before 2022. Agencia Tributaria: transfer-deferral rules
If you plan to move repeatedly between US and eurozone allocations, consider the tax consequences of selling. New contributions can help adjust the balance without immediately realising a gain.
Across countries, keep taxes incurred within the fund separate from your own tax on investment income and gains. An accumulating share class reinvests income; it does not create a Europe-wide tax exemption. Finorum’s accumulating vs distributing ETFs guide explores that distinction.
Which approach fits your portfolio?
| Situation | Question to answer first | Practical consequence |
|---|---|---|
| Investing €100 a month for the first time | Do you need a regional allocation at all? | Avoid splitting small orders unless each holding has a purpose |
| Building a €10,000 equity portfolio | Are you comfortable excluding other major markets? | Compare a global fund before committing to either region |
| Already own a global ETF | Which exposure are you deliberately increasing? | Calculate the portfolio’s resulting regional weights |
| Manage regions separately | What target weights will you maintain? | Decide how and when you will rebalance |
| Moving between countries | How will tax residence and reporting change? | Check the treatment of existing holdings before making changes |
Choose an S&P 500 UCITS ETF when your plan calls for large US equities and you accept the concentration and currency exposure.
Choose a Euro Stoxx 50 ETF when you want a focused allocation to large eurozone companies.
Consider both when you have chosen regional weights and a way to maintain them.
For broad long-term equity diversification, compare those approaches with a global ETF before constructing a portfolio from separate regional holdings.
How much of a fall could you tolerate?
Both choices remain equity investments. In an illustrative 40% decline, €10,000 becomes €6,000. Recovering from €6,000 to €10,000 then requires a gain of approximately 66.7%.
Your time horizon matters because you may need the money before a recovery occurs. Retirement savings intended for decades from now have a different purpose from a house deposit required in two years. Even a long horizon does not guarantee recovery by a particular date.
Also read the Key Information Document for the exact ETF. Funds tracking the same benchmark can use different implementation methods and produce slightly different results because of expenses, withholding taxes, securities lending, cash holdings and other tracking effects.
Frequently asked questions
Is Euro Stoxx 50 the same as STOXX Europe 600?
No. Euro Stoxx 50 holds 50 large eurozone companies. STOXX Europe 600 covers 600 companies across a wider group of European markets, including the UK and Switzerland, with large-, mid- and small-cap exposure. STOXX Europe 600
Does a lower ETF share price mean the fund is better value?
No. A €20 unit is not inherently better value than a €200 or €500 unit. Unit price affects how precisely you can invest a cash amount when fractional purchases are unavailable. Fund charges and the valuations of the underlying businesses are separate questions.
Should I compare ETF market-price returns or NAV returns?
Use equivalent NAV total-return figures with the same dates and currency for a consistent fund comparison. Your personal result can differ because you trade at exchange prices and incur spreads, commissions and taxes.
Can I switch between exchange listings of the same ETF?
First verify that the ISIN is identical, then check your broker’s procedures. A share class can have several listings and trading currencies, but moving a position between venues may involve restrictions or charges.
What if I live in Poland or Sweden rather than the eurozone?
Measure the result against the currency in which you expect to spend the money. A EUR trading line does not remove exchange-rate exposure relative to PLN or SEK. The euro calculations here therefore do not represent your complete currency result.
Should I sell my current ETF because another has a lower TER?
Calculate the saving and the cost of switching. Moving from 0.10% to 0.07% saves approximately €3 annually on a constant €10,000 holding. Dealing fees, spreads and any tax triggered by selling could outweigh that saving.
