VUAA, SXR8 and the other S&P 500 ETFs: how to choose

What are the alternatives to VUAA on the S&P 500?

The same index is tracked by iShares’ SXR8, by the distributing versions VUSA and IUSA, as well as by ETFs from other providers, with differences mainly in size, cost and replication method.

The ETFs below are educational examples, not recommendations. Their annual charges come from the providers’ own pages and factsheets, as checked in September 2026.

SXR8 (CSPX) from iShares

The iShares Core S&P 500 UCITS ETF USD (Acc) is the closest alternative to VUAA: the same index, physical replication, reinvested dividends and a 0.07% TER. It is also one of the largest S&P 500 ETFs in the world.

On Xetra it trades as SXR8 in euros and on the London Stock Exchange as CSPX in dollars. It is the same share class of the same fund, with the same ISIN, the same portfolio and the same TER, so only the exchange, the ticker and the trading currency change.

Its difference from VUAA lies mainly in size and liquidity. In August 2026 SXR8 had Xetra turnover of 362.7 million EUR against 98.0 million EUR for VUAA and a lower execution cost: 1.79 against 2.18 basis points for buying and selling 100,000 EUR, according to the Deutsche Börse XLM measure. The CSPX and VUAA comparison on the ETF Hub shows the key data of the two funds side by side.

The distributing versions: VUSA and IUSA

A distributing version pays out to the investor the dividends it receives, instead of reinvesting them inside the fund as VUAA and SXR8 do.

• VUSA (Vanguard): the Vanguard S&P 500 UCITS ETF (USD) Distributing, ISIN IE00B3XXRP09, is a second share class of the same fund as VUAA. It has a 0.07% TER, pays dividends every quarter and trades as VUSA on Xetra in euros and as VUSD on the London Stock Exchange in dollars.
• IUSA (iShares): the iShares Core S&P 500 UCITS ETF USD (Dist), ISIN IE0031442068, is a separate iShares fund launched in 2002 with a 0.07% TER. It pays dividends every quarter and trades as IUSA on Xetra in euros and as IDUS on the London Stock Exchange in dollars.

VUAA and VUSA share the same portfolio. On 31 August 2026 the whole Vanguard fund held about 89 billion dollars, of which about 36 billion belonged to VUAA and 53 billion to VUSA.

ETFs from other providers

Besides Vanguard and iShares, other large providers also run S&P 500 UCITS ETFs. Each provider names the annual charge differently (TER, ongoing charge or all-in fee) and synthetic ETFs may also carry a swap cost:

• State Street SPDR: the SPDR S&P 500 UCITS ETF comes in an accumulating version (SPYL) and a distributing version (SPY5). Both have a 0.03% TER and physical replication.
• Invesco: the Invesco S&P 500 UCITS ETF Acc (P500 on Xetra) has an ongoing charge of 0.05% and synthetic replication. This means it receives the index return through an exchange agreement (swap) with counterparty banks, instead of holding the shares of the index. Invesco also reports a swap fee of 0.07% a year, which is not charged separately but is included in the return the swap delivers.
• Xtrackers (DWS): the Xtrackers S&P 500 Swap II UCITS ETF 1C (X500) has a 0.04% TER as of 30 September 2026 and also uses synthetic replication through a swap. DWS states that the 0.04% rate is a temporary fee waiver that it intends to make permanent.
• Amundi: the Amundi Core S&P 500 Swap UCITS ETF Acc (LYP5 on Xetra, SP5C on Euronext Paris) has a 0.05% TER and also uses synthetic replication.

On a portfolio of 10,000 €, the gap between a 0.07% TER and a 0.03% TER comes to about 4 € a year. TER, however, does not include the spread or the platform charges. For the same index, the size of the fund, the liquidity on the exchange you use, the charges and the availability on your platform may weigh more than this gap.

There are also ETFs and share classes with currency hedging into euros (EUR Hedged), such as the iShares S&P 500 EUR Hedged UCITS ETF (Acc) with a 0.20% TER. They reduce the effect of the EUR/USD exchange rate at a higher cost, without eliminating it completely.

The VUAA and SPYL comparison shows two of these funds side by side, while the Logifin ETF Hub holds the profiles of the other UCITS ETFs.

Do S&P 500 ETFs differ in performance?

Not in any meaningful way. ETFs that track the same index follow an almost identical path, while their small differences come from costs and from the way they replicate the index.

VUAA and SXR8 show this. Over the five years to 31 August 2026, the average annual return based on net asset value in dollars was 12.48% for VUAA and 12.49% for SXR8, a gap of 0.01 percentage points a year.

Such deviations do not change an investor’s strategy or justify frequent ETF switching.

⚠️ These deviations do not arise because one ETF “invests better” than the other. They arise mainly from technical reasons, such as:

• exactly when the dividends are reinvested inside the ETF
• small differences in the total operating cost
• the efficiency of the index replication on a daily basis

For this reason TER on its own is not enough to explain the differences in performance. What counts in practice is the tracking difference, meaning the actual gap between the return of the ETF and the return of the index after all costs and operating details.

For someone who invests over a horizon of decades, consistency in replicating the index and discipline in the strategy play a much larger role than which ETF had slightly better performance in a specific period.

How does the EUR/USD exchange rate affect your final return?

One of the most frequent points of confusion when comparing S&P 500 ETFs concerns the currency.

⚠️ Many investors think that the ETF trading in euros has different exposure to the dollar from the one trading in dollars.

In practice, this is not the case. All the ETFs in this article invest in the same American companies of the S&P 500, which are priced in dollars.

Regardless of the currency in which the ETF trades on the exchange, the investor has full exposure to the EUR/USD exchange rate.

• If the dollar strengthens against the euro, the return in euros increases.
• If it weakens, the return in euros decreases.

The currency in which you buy the ETF does not change this relationship. It only affects the way you see the price on your screen and how the transaction is settled.

The underlying investment remains the same. Over time, the exchange rate can create periods where the return of the S&P 500 in euros diverges noticeably from the return in dollars.

There were years where the strengthening of the dollar worked in favour of the European investor, but also periods where the opposite reduced the returns. None of these ETFs has a currency-hedging mechanism, so the return you see always combines the path of the index with the movement of EUR/USD.

💡 For a long-term investor, the exchange rate works more as a factor of volatility than as a criterion for choosing an ETF.

Its effect is the same for all unhedged ETFs on the index, so the choice between them does not depend on the trading currency. With DCA purchases happen at different exchange rates, while in a lump-sum investment the exchange rate at the moment of entry can make a difference to the final return.

Cost, spread and brokers

When ETFs on the same index show similar performance, attention reasonably turns to cost. Here, however, a closer look is needed, because cost is not limited to the TER written on the factsheet.

In practice, the spread and the platform charges can weigh more than the TER gap between ETFs on the same index.

VUAA and SXR8 have a 0.07% TER, while the SPDR ETFs go down to 0.03%. As the 10,000 € example showed, this gap comes to about 4 € a year.

In everyday practice the spread carries more weight, that is the difference between the buying price and the selling price at the moment of the transaction.

• The spread is directly linked to the liquidity of the ETF and the trading volume on the exchange where it trades.
• An ETF with high assets and large daily volume tends to have smaller spreads, therefore a lower hidden cost for the investor.

At this point SXR8 often shows a small practical advantage, since it is among the largest and most actively traded S&P 500 ETFs in Europe. This does not mean that VUAA has a liquidity problem: both are considered adequate for retail investors, while the difference mainly concerns those who trade frequently or invest large amounts.

Beyond the ETF itself, the buying platform also plays an important role. Commissions, whether free ETF buying is offered and whether there is a regular-investing plan can affect the final result more than the difference between two ETFs on the same index.

On small monthly purchases, a fixed minimum commission weighs more: 3 € on a 200 € purchase is 1.5% of the order, while on a 6,000 € purchase it is 0.05%.

This is why it makes sense to look at the overall picture. Not only which ETF you choose, but also:

• on which exchange it trades
• what the commission per transaction is
• whether the platform easily supports the strategy you want to follow

The main differences between platforms are gathered on the Logifin Online Brokers page.

How do you choose an S&P 500 ETF for a DCA plan?

In a DCA (Dollar Cost Averaging) strategy, an ETF you can buy steadily and without friction matters more than the “perfect” ETF.

Any large S&P 500 UCITS ETF can be used for DCA, so the choice comes down to practical criteria: liquidity, the price per share, the support of your platform and the consistency it allows.

Liquidity and trade execution

• Large ETFs on the index, such as VUAA and SXR8, are sufficiently liquid for retail investors.
• The larger size and higher volume of SXR8 on Xetra often translate into slightly smoother execution, especially in periods of high volatility.

Share price and practical flexibility

• The lower price per share of VUAA can make it easier to invest fixed amounts when the platform does not offer fractional shares.
• This leaves a smaller unused balance after each purchase.

Platform support

• Many brokers offer regular-investing plans for specific ETFs with low or zero commissions.
• Often the final choice is not determined by the ETF but by which one is best supported in the plan you use.

Consistency and discipline

• The fewer obstacles there are in practice, the easier it is to keep to the plan.
• Stable access, good liquidity and simple processes help more than any small difference in features.

The “right” choice is the one that fits your amount, frequency and platform, so that the strategy is applied without interruptions over time.

What should you check and what should you avoid?

The choice between VUAA and its alternatives is not a matter of a “good” and a “bad” ETF, since the large UCITS ETFs on the index are low-cost and reflect the path of the S&P 500 with consistency.

The differences that matter are practical:

• Size and liquidity: SXR8 has larger assets and more trading on Xetra, which matters mainly for large or frequent orders.
• Price per share: VUAA has a lower price per share, which matters mainly when the platform does not offer fractional shares.
• Annual charge: the SPDR ETFs (SPYL, SPY5) have a 0.03% TER, while the ETFs from Invesco, Xtrackers and Amundi track the index with synthetic replication, through a swap.
• Dividends: the distributing versions (VUSA, IUSA, SPY5) pay the dividends to the investor, while the accumulating versions reinvest them.

⚠️ What is worth avoiding is excessive focus on small differences. Switching ETFs based on minimal performance deviations or temporary cost differences usually adds complexity without real benefit.

Whichever ETF on the index you choose, the result will depend mainly on the duration of the investment, the regularity of the purchases and the ability to stay on the plan, even in periods of high volatility. The ETF is the tool. The strategy is what determines the final result.

Conclusion and practical takeaways

VUAA is one of many UCITS ETFs that track the S&P 500. Choosing it or one of its alternatives will not, on its own, determine the success or failure of an investment strategy.

The large UCITS ETFs on the index offer low-cost and consistent exposure to the S&P 500, so the plan matters more than the ETF itself.

The real goal is not to find the “perfect” ETF but to fit the investment into a plan that can be applied with consistency over time. The small technical differences matter far less than the duration, the discipline and the psychology of the investor, especially in periods of high volatility.

What to keep in mind:

• Same index, small differences: VUAA, SXR8 and the other S&P 500 UCITS ETFs differ mainly in size, cost, trading currency and dividend policy.
• Consistency: long-term performance comes from consistency and not from comparing small differences between similar products.
• Portfolio core: a broad-based ETF can be the core of a portfolio, but whether it fits depends on the goals, the horizon and the risk each investor can bear.
• Currency: currency and market fluctuations are part of the journey and not a reason to change strategy.
• Cost: low cost and reliable index replication matter more than short-term performance deviations.

Practical tips for new investors:

1. Start simple

   You do not need to choose many ETFs to invest in the S&P 500. ETFs on the same index give almost the same exposure to the companies in the index, so holding more than one does not add meaningful diversification at the stock level.

2. Keep a steady monthly plan

   A fixed amount every month, through a standing order where your platform allows it, is the essence of DCA. It reduces emotional noise and helps you stay consistent, whatever the market conditions.

3. Do not focus on the monthly return

   Short-term moves say nothing about the success of a plan that spans decades. What matters is time in the market.

4. Avoid frequent ETF changes

   Jumping from product to product rarely adds value and often undermines your strategy.

5. Review your plan periodically, not constantly

   A periodic check, at a frequency that suits your plan, is enough to see whether your strategy remains aligned with your goals and your financial reality.
