ETFs vs Mutual Funds: Which Should You Choose?

If you are starting to invest in South Africa, you will quickly meet two popular options: exchange traded funds (ETFs) and mutual funds, which are known locally as unit trusts. Both let you pool your money with other investors and own a spread of shares, bonds or property, but they work differently in ways that affect your costs, your flexibility and your results. This guide explains the differences in plain language so you can decide which one fits your situation.

What Is an ETF?

An exchange traded fund is a basket of investments that trades on a stock exchange, such as the JSE, just like an individual share. Most ETFs are designed to track an index, for example the top listed companies in South Africa or a global equity index. When the index rises or falls, the ETF aims to follow it, less its costs.

Because ETFs trade on an exchange, you buy and sell them through a stockbroker or an investment platform. The price moves during the trading day, and you can usually buy as little or as much as your platform allows. Many South African platforms and banks now offer access to local and offshore ETFs, so it is worth comparing providers.

What Is a Unit Trust (Mutual Fund)?

A unit trust is a collective investment scheme run by a management company. You buy units in the fund, and your money is pooled with that of other investors. A portfolio manager then decides what to buy and sell inside the fund. Some unit trusts are actively managed, meaning the manager tries to beat a benchmark, while others are index-tracking and behave much like ETFs.

Unit trusts are priced once a day, and you buy or sell at that day's price directly through the management company, a financial adviser, or a linked investment services provider (LISP) platform. Many allow regular monthly debit orders, which makes them convenient for people who want to invest steadily.

Key Differences at a Glance

Management Style

Most ETFs are passive, following an index with no manager making stock-picking decisions. Unit trusts can be either passive or active. If you want a manager trying to outperform the market, an active unit trust is the usual route, although there is no guarantee that any manager will succeed, and many do not over the long term.

Costs

Cost is often the deciding factor. Passive ETFs typically have lower ongoing fees than actively managed unit trusts, because there is less research and trading involved. However, ETFs carry other costs, including brokerage when you buy or sell, and sometimes a small gap between buying and selling prices. Unit trusts may charge an annual management fee, and platforms or advisers may add their own charges. Always read the fund's fact sheet and check the current total cost with the provider, and do not look only at the headline fee.

Understanding how small cost differences add up over time is crucial. For a deeper look at this, read our guide on how compound interest actually builds wealth, which shows why even modest fees can matter over decades.

Trading and Flexibility

ETFs can be traded throughout the trading day, so you can react to market moves, although for long-term investors this is rarely an advantage. Unit trusts are bought and sold at a single daily price, and withdrawals can take a few days to reach your bank account. If you value simplicity and automation, the daily pricing of a unit trust is not a real drawback.

Minimum Investment and Regular Contributions

Minimums vary widely between providers. Some unit trusts and platforms accept small monthly debit orders, while some ETF routes require you to place a trade each time. Check the current minimums and any contribution rules with the provider before you commit.

How They Are Taxed in South Africa

Tax treatment depends on how you hold the investment, not just on whether it is an ETF or a unit trust. Outside a tax-advantaged account, you may owe tax on interest, dividends and capital gains according to current South African Revenue Service (SARS) rules. Local dividends and foreign dividends are treated differently, and the rules change from time to time, so confirm the current position with SARS or a registered tax practitioner.

One of the most useful tools for local investors is the tax-free savings account (TFSA). Both ETFs and unit trusts can be held inside a TFSA, where growth is currently not taxed, subject to annual and lifetime contribution limits set by government. Check the current limits and the penalties for exceeding them before you contribute. Retirement annuities are another option that can hold unit trusts and ETFs, with their own tax rules and access restrictions.

Who Should Consider an ETF?

• Cost-conscious investors who want broad market exposure at a low ongoing fee.
• Hands-on investors comfortable using a broker or platform and placing their own trades.
• People who want transparency, since index-tracking ETFs are easy to understand and the holdings are published.

Who Should Consider a Unit Trust?

• Investors who prefer automation and want to set up a monthly debit order and leave it alone.
• People seeking active management or a specific strategy, such as a balanced fund that adjusts its mix of assets for you.
• Those who want professional guidance, since many unit trusts are sold through financial advisers who can help with goal setting.

Balanced and multi-asset unit trusts can be helpful if you do not want to decide how to split your money between shares, bonds, property and cash yourself. Keep in mind that advice and platform charges add to the cost, so ask for a clear breakdown before you sign.

Common Mistakes to Avoid

Chasing Past Performance

A fund that did well recently is not guaranteed to keep doing so. Past returns are not a reliable guide to the future, and every investment carries the risk that you could lose some or all of your money.

Ignoring Total Costs

Look beyond the fund's own fee. Platform fees, adviser fees, brokerage and currency conversion costs for offshore funds all reduce your return. Our article on bank fees you should never pay is a good reminder to question every charge.

Investing Money You May Need Soon

Both ETFs and unit trusts can fall in value, sometimes sharply. Money you will need in the near term may be better kept in a savings product. If you are unsure where the line falls, see our comparison of saving versus investing.

Overlooking Currency and Offshore Risk

Funds that invest offshore are exposed to exchange rate movements, which can help or hurt your returns in rand terms. There may also be rules on how much you can move offshore, so check the current regulations with your provider.

So, Which Should You Choose?

There is no single right answer. A low-cost, index-tracking ETF suits many long-term investors who are comfortable with a platform and want to keep fees down. A unit trust may suit you better if you value automatic monthly investing, a managed strategy or the support of an adviser. Many investors use both, holding ETFs for core market exposure and a unit trust for a specific goal or a hands-off retirement strategy.

Before you decide, compare the current total cost, minimum investment, tax treatment and available accounts, such as a TFSA or retirement annuity, with each provider. Read the fund fact sheet and risk disclosures, and consider speaking to a registered financial services provider (FSP) if your situation is complex. Remember that all investments carry risk, returns are never guaranteed, and the right choice depends on your goals, your time horizon and how comfortable you are with market ups and downs.
