Neither fund is universally better. A JSE Top 40 tracker gives concentrated exposure to the largest companies listed in South Africa, while an S&P 500 feeder ETF gives US large-company exposure and adds rand–US-dollar currency movements to your result. Choose according to the exposure your portfolio lacks, your tolerance for concentration and currency risk, total fund costs, tax treatment and investment horizon. Recent published returns cannot establish a winner unless the dates, currency, dividend treatment, benchmark and fund costs are aligned.

What do the JSE Top 40 and S&P 500 actually represent?
The FTSE/JSE Top 40 consists of the 40 largest companies listed on the JSE, ranked by investable market capitalisation within the FTSE/JSE All-Share Index. A tracker normally holds the constituents in similar weights to follow that benchmark. It is therefore a large-cap South African-listed equity index, not a portfolio of every local company and not a complete measure of the domestic economy.
An S&P 500 feeder ETF is a locally available access vehicle for US large-company shares. The ETF may trade in rand on the JSE, but the underlying economic exposure remains foreign. The feeder’s domicile, replication method, distribution policy, currency treatment and tracking results differ by product; confirm each item in the individual fund documents rather than assuming that all S&P 500 ETFs work identically.

Both are equity investments. The value can fall substantially, and a long time horizon does not guarantee a profit. Sygnia labels its Top 40 ETF high risk and states that the manager gives no guarantee of capital or return in its fund information.
Should a South African investor choose local shares or US shares?
Start with the role the holding must play. If your salary, emergency fund, property and retirement assets are already heavily tied to South Africa, adding a Top 40 fund may increase home-country concentration. If your portfolio has little foreign equity, an S&P 500 feeder can add a different market and currency. Conversely, an investor with substantial offshore holdings may need local exposure for rand spending rather than another US allocation.

“Diversification” does not mean that either index is diversified across the whole world. The Top 40 is concentrated in 40 domestic large-cap companies; the S&P 500 is concentrated in one country’s large-company market. A globally diversified portfolio would require additional regions, company sizes and asset classes. These two funds can be building blocks, but neither is automatically a complete portfolio.
When the Top 40 may fit
- You expect to spend most of the money in rand and want less direct rand–dollar translation in the account statement.
- You need South African listed-equity exposure and accept concentration in a small number of large companies.
- You want a locally focused equity component alongside cash, bonds or offshore assets.
When an S&P 500 feeder may fit
- You want exposure to US large companies without opening a foreign brokerage account.
- Your existing investments are dominated by South African assets and you want geographic diversification.
- You can tolerate the rand value moving because of both US share prices and exchange rates.
How does currency change the S&P 500 result in rand?
A rand investor’s return from an unhedged foreign-equity fund is approximately the underlying share return plus or minus the change in the rand–US-dollar exchange rate, before fees, taxes and tracking effects. If US shares rise while the rand weakens, the currency translation can increase the rand return. If the rand strengthens, it can reduce or even outweigh a positive US-dollar share return. The opposite applies when US shares fall.

A South African listing in rand does not by itself remove this exposure. Check whether the specific fund hedges currency, how often it rebalances any hedge and what the hedge costs. The provider’s ETF information and the fund fact sheet should state the structure and currency policy.
The Top 40 has its own indirect foreign sensitivity. Several JSE-listed companies earn revenue outside South Africa, so their share prices can respond to global commodities, currencies and overseas economies. That is different from holding a US index directly: the listing country and the revenue geography are not the same thing.
What do the published returns show—and why can’t they crown a winner?
Use total returns with dividends reinvested, measured over the same dates, in the same currency and on the same basis. The available figures are not aligned: ETFSA reports a benchmark series through 29 May 2026, while 10X reports a particular S&P 500 ETF through 30 September 2026. They also differ in whether the number is an index or fund return and in how costs and taxes are reflected.
| Series | Period and end date | Published total return | What it represents |
|---|---|---|---|
| FTSE/JSE Top 40 | One year to 29 May 2026 | 26.54% | ETFSA benchmark total return with dividends reinvested |
| FTSE/JSE Top 40 | Three years annualised to 29 May 2026 | 18.01% | ETFSA benchmark total return with dividends reinvested |
| FTSE/JSE Top 40 | Five years annualised to 29 May 2026 | 15.71% | ETFSA benchmark total return with dividends reinvested |
| FTSE/JSE Top 40 | Ten years annualised to 29 May 2026 | 11.80% | ETFSA benchmark total return with dividends reinvested |
| 10X S&P 500 ETF | One year to 30 September 2026 | 10.9% | Specific fund performance reported by 10X |
| 10X S&P 500 ETF | Three years annualised to 30 September 2026 | 16.8% | Specific fund performance reported by 10X |
| 10X S&P 500 ETF | Five years annualised to 30 September 2026 | 15.1% | Specific fund performance reported by 10X |
These numbers are useful context, not a head-to-head scorecard. The end dates differ by four months, the Top 40 figures are an index series and the S&P 500 figures are a fund series, and the reports may use different currency, tax and fee conventions. A proper comparison would download both funds’ latest fact sheets, choose one common date, compare net total returns in rand and inspect each fund’s tracking difference.

Which costs matter beyond the TER?
The total cost of ownership can include the total expense ratio (TER), transaction costs inside the fund, bid–ask spread, brokerage or platform charges, taxes and the return lost through tracking difference. A lower TER is helpful, but it does not guarantee the closest result to the index or the lowest all-in cost for your trade size.
| Fund example | TER | Transaction cost | Total investment cost | Source date |
|---|---|---|---|---|
| FNB Top 40 ETF | 0.12% | 0.06% | 0.19% | Displayed 2 July 2026 |
| FNB S&P 500 Feeder ETF | 0.20% estimated | 0.02% estimated | 0.22% estimated | Displayed 2 July 2026 |
| 10X S&P 500 ETF | 0.37% | Not stated in the cited figure | Not stated in the cited figure | Table dated 30 September 2026 |
The FNB figures come from its ETF listing and the 10X figure from its performance data. They should not be treated as permanent prices. Before buying, check the current TER, estimated transaction cost, fund spread, brokerage, minimum order rules and any platform fee. For a small monthly contribution, a dealing fee can matter more than a few hundredths of a percentage point in TER; for a large, long-held balance, recurring fund expenses and tracking difference become more significant.

SARS guidance says dividends paid by South African companies to individuals are generally exempt from income tax, while dividends tax of 20% is withheld. Most foreign dividends received by an individual who owns less than 10% of the foreign company are taxable at a maximum effective rate of 20%, subject to the applicable rules and foreign-tax-credit limits.
An ETF can change where and when tax is deducted. A feeder fund may incur withholding tax in the foreign market before income reaches the South African vehicle, and the fund’s distribution policy may affect what you receive personally. Your account type, residency, marginal tax position and other income also matter. Read the fund’s tax certificate and current disclosures; do not apply the headline 20% rates mechanically to every product.

SARS explains the limits on foreign tax credits in its foreign-tax-credit FAQ. Tax rules can change, so obtain current guidance or professional advice for a material investment decision.
What risks are easy to underestimate?
- Concentration risk: Forty shares are fewer than a broad global portfolio, and index weights can be dominated by the largest constituents or sectors.
- Currency risk: An unhedged S&P 500 holding can move sharply in rand even when its US-dollar price changes little.
- Market risk: Both funds can lose substantial value during an equity sell-off. Neither is a cash substitute.
- Tracking risk: Fund expenses, tax leakage, rebalancing, corporate actions and replication choices can make the ETF lag its index.
- Trading risk: A wide spread or thin market at the time of your order can make your execution price worse than the quoted mid-price.
- Timing risk: A one-year result says little about the return you will earn over your own holding period.
How should you compare two actual ETFs before buying?
Use this process whenever you are comparing a Top 40 fund with an S&P 500 feeder, or two products tracking the same index.

Write down whether the money is for rand spending, long-term growth, offshore diversification or a specific liability. Identify the South African and foreign exposure you already have.
- Confirm the benchmark and structure. Verify that the first fund tracks the FTSE/JSE Top 40 and that the second is genuinely linked to the S&P 500. For the feeder, record the underlying fund, domicile, replication method and whether currency is hedged.
- Set one measurement date. Compare the same start and end dates. Use total returns with reinvested distributions, and make sure both figures are either net fund returns or benchmark returns.
- Convert to a common currency. For a rand-based decision, compare rand returns. Separately inspect the underlying US-dollar return and the exchange-rate contribution so a currency windfall is not mistaken for manager skill.
- Calculate all-in costs. Add TER, transaction costs, brokerage, platform charges and the expected bid–ask spread. Check whether costs are estimates and note the date shown.
- Review tracking quality. Compare the fund’s return with its benchmark over several periods. A persistent gap larger than the stated expenses deserves an explanation.
- Read the tax documents. Check distribution statements, foreign withholding, dividends-tax treatment and the rules for your account. Keep records for tax filing.
- Stress-test the decision. Ask how you would react to a 20% equity decline, a sharp rand move and a period in which the chosen market lags the other. If the answer would force a sale, the allocation may be too large.
- Check liquidity before ordering. Review the live spread, trading volume and order type. A limit order can help control execution price, but it does not guarantee a fill.
Is one index fund enough for a long-term portfolio?
Usually not. The Top 40 leaves out smaller South African companies, bonds, cash and foreign assets. The S&P 500 leaves out non-US markets, smaller companies, local-currency assets and defensive investments. The appropriate mix depends on your goals, horizon, income needs and ability to tolerate losses.
Think of the choice as an allocation decision rather than a permanent verdict. You can hold a local and a foreign equity fund in proportions that match your liabilities and risk capacity, then rebalance according to a written rule instead of chasing whichever index recently led. Rebalancing can create transaction costs and tax consequences, so set a practical threshold and review it when your circumstances change.

Bottom line: which is better for a South African investor?
Choose the JSE Top 40 when you specifically need South African large-cap exposure and accept its concentration. Choose an S&P 500 feeder when you need US equity exposure and can accept rand–dollar volatility, foreign-tax complexity and the particular costs of the fund you select. Compare matched, after-fee rand total returns only after checking the current fact sheet. For many investors, the sensible answer is not “one wins”, but a deliberately sized combination that avoids overloading either one market.
Frequently Asked Questions
Does a rand-listed S&P 500 ETF remove currency risk?
No. Trading the ETF in rand only determines the dealing currency. Unless the product explicitly hedges, the value still reflects the US holdings and movements in the rand–US-dollar exchange rate; confirm the hedge policy in the latest fact sheet.
Why can my ETF return differ from the index return?
The fund pays operating and transaction costs, may suffer withholding-tax leakage and can experience tracking effects from replication, rebalancing and cash balances. Your personal result also includes the price at which you bought, sold and reinvested distributions.
Are dividends from a Top 40 ETF completely tax-free?
Not necessarily. SARS generally exempts South African dividends from an individual’s income tax but applies 20% dividends tax at source, and the ETF’s own holdings and distributions can affect the final amount. Use the fund’s tax certificate and current SARS rules for your circumstances.
Can I compare a benchmark return with an ETF return directly?
Only with care. Align the dates, currency, dividend reinvestment and fee treatment first; an index total-return figure and a net fund return answer different questions. The published Top 40 and 10X figures in this guide use different end dates and should not be ranked as a clean contest.
What should I check if two S&P 500 ETFs track the same index?
Compare their feeder or replication structure, domicile, currency hedge, TER, transaction costs, spread, liquidity, distribution policy and multi-year tracking difference. The lower headline TER is not automatically the lower total cost for your account.
