You open an investment statement and see terms like TER, benchmark, asset class, risk profile and capital gains tax — and suddenly it feels like you need a finance degree just to understand what you own.
You don't.
Most investment jargon exists to answer a handful of fairly simple questions: what am I invested in, how does it work, what does it cost, what risks am I taking, and what do I actually keep after tax? Understanding those questions is far more useful than memorising a list of definitions. Here's what some of the most common terms actually mean — and, more importantly, why they matter when you look at your own portfolio.
What am I actually invested in?
Before looking at returns, start with the basics: what does your money ultimately own? Your underlying investments are the assets you have exposure to — shares, bonds, property or cash. The product you buy is often simply the structure through which you access those assets, which is where ETF and unit trust come in.
Units trade on a stock exchange during market hours, much like a share. An ETF can be passive, aiming to track an index — a basket of investments designed to represent a particular market, such as the largest companies in South Africa or the US stock market — or actively managed, where a manager decides what to buy and sell rather than simply following an index.
A collective investment scheme in which investors own units in a pooled portfolio. Unlike an ETF, units aren't continuously traded on an exchange — they're generally bought and sold through the fund manager or an investment platform, priced according to the fund's valuation.
A broad category of investment: equities (shares in companies), bonds (debt issued by governments or companies), property, and cash or money-market instruments. Different asset classes behave differently in different conditions, which is why portfolios are usually spread across more than one.
An ETF isn't automatically better than a unit trust, or the other way around. The more useful questions are what it invests in, what it costs, how it behaves, and whether it suits what you're trying to achieve.
Active vs. passive: how is the investment managed?
The structure of an investment tells you how you access it. The strategy tells you how the money is managed.
Rather than trying to select the "best" shares, the fund follows predetermined rules designed to replicate its chosen index, before costs — providing broad market exposure without a manager making constant decisions.
Managed by a manager or team who decide what to buy, hold or sell, aiming to outperform a benchmark, manage risk differently, or achieve some other defined outcome. For an active fund, don't just look at recent returns — understand how the manager invests and why they believe that approach works.
Don't confuse an ETF with an index fund
These terms are often used interchangeably, but they describe different things — an ETF can be an index fund, but it doesn't have to be, and an index-tracking fund can just as easily exist as a unit trust.
| What it describes | |
|---|---|
| ETF | The structure through which the investment is traded |
| Index fund | A strategy designed to track an index |
| Active fund | A strategy involving active investment decisions |
ETF describes the structure. Passive or active describes the strategy.
How do I judge an investment?
Knowing what you own is only the beginning. The next question is whether the investment is doing what it's supposed to do — and that starts with a benchmark, the reference point used to assess performance. A South African equity fund, for example, might use an appropriate SA equity index.
Imagine two funds both returned 10% over the same period. Fund A's benchmark returned 6%. Fund B's benchmark returned 14%. The identical return tells you very different things about the two funds — which is why the return alone never gives you the full picture. (It only works, though, when the benchmark is appropriate: you wouldn't judge a money-market fund against a global equity index.)
A benchmark turns “did my investment make money?” into “how did it perform relative to what it's supposed to represent?”
For an index-tracking fund specifically, it's also worth checking its tracking difference — how closely it has actually followed its benchmark over time, after costs. A fund can have a low advertised fee and still fail to track its index as closely as expected, so don't only ask what the TER is; also ask how closely the fund has actually tracked its benchmark.
Return, risk and volatility
“This fund returned 15% last year.” Sounds good — but that number is incomplete without some idea of the risk taken to achieve it. Volatility describes how much an investment's value moves up and down over time. Higher volatility means a wider range of short-term outcomes. It doesn't automatically mean permanent loss, but large swings can make an investment harder to hold through a rough patch — particularly if you might need the money soon. A long-term investor and someone saving for a deposit next year shouldn't necessarily be taking the same amount of risk.
Inflation matters too: if an investment earns 8% while inflation runs at 5%, your purchasing power hasn't grown by 8%. What you actually gained after inflation is your real return — and that's the number that matters, since the point of investing isn't a bigger figure on a statement, it's what that money can actually buy.
Asset allocation and diversification
Asset allocation — how your portfolio is divided between equities, bonds, property and cash — is one of the biggest drivers of its overall risk and return, and it should reflect what the money is for: what you need soon has very different requirements from money you won't touch for decades.
Diversification means spreading investments across companies, sectors, regions or asset classes rather than relying too heavily on one area, to reduce the impact of any single investment performing badly. But owning lots of funds doesn't automatically mean you're diversified — you can hold five different funds and still have a large chunk of your portfolio in the same companies or sectors.
The better question isn't “how many investments do I have?” It's “what do I actually own across my entire portfolio?”
What am I paying?
The Total Expense Ratio (TER) measures a fund's ongoing operating costs as a percentage of its assets. You won't get a separate bill for it — it's simply reflected in the fund's returns, whether the fund makes money or loses it. But TER isn't the same thing as the total cost of investing: advice fees, administration or platform fees, brokerage, transaction costs and potentially performance fees can all sit on top of it, which is why comparing funds on TER alone gives an incomplete picture. The better question is what the investment costs you in total, and what you're getting for that cost.
R1 million invested for 30 years at 8% a year grows to roughly R10.1 million; at 7%, roughly R7.6 million. A seemingly small annual difference becomes significant over long periods through compounding — but that doesn't make the lowest-fee investment automatically the right one. A meaningful comparison weighs total cost, performance after costs, benchmark, risk and objective together.
What tax applies?
The tax treatment of an investment can make a real difference to what you actually keep — and it depends heavily on what you own and where you own it.
Can apply when you dispose of an investment for more than its base cost. For 2026/27, individuals get an annual exclusion of R50,000; after that, only 40% of the remaining gain is added to your taxable income and taxed at your marginal rate — not the whole gain.
Generally charged at 20% on dividends paid by South African companies to individuals, withheld before the money reaches you. Certain structures — a retirement fund or tax-free investment, for example — get different treatment, which is one reason it matters whether you're investing personally or through one of those.
TFSA vs. RA: similar tax benefits, very different purposes
A qualifying Tax-Free Investment (TFSA) provides tax-free growth — returns are exempt from income tax, Dividends Tax and CGT. For 2026/27, the annual contribution limit is R46,000 and the lifetime limit remains R500,000; importantly, these are contribution limits, not a cap on the account's value — growth inside it can take the balance well above R500,000.
A Retirement Annuity (RA) is designed specifically for retirement. Contributions can qualify for a tax deduction, generally limited to the lesser of 27.5% of the relevant income or R430,000 for 2026/27 — but access is far more restricted, since an RA is designed to stay invested until retirement.
| TFSA | Retirement Annuity | |
|---|---|---|
| Main purpose | Tax-free investing for a range of goals | Retirement provision |
| Annual contribution limit | R46,000 | 27.5% of relevant income, capped at R430,000 |
| Deduction for contributions | No | Yes, subject to the applicable rules |
| Tax on investment returns | Exempt | Depends on the retirement-fund structure |
| Access | Withdraw anytime — but a withdrawal doesn't free up more room; drawing out R50,000 doesn't give you R50,000 more lifetime allowance to put back | Locked away until at least age 55, with limited exceptions |
| Unused annual contribution room | Does not carry forward | Contribution rules differ |
A TFSA offers greater flexibility but limited contribution room. An RA offers a potential upfront deduction and a retirement-focused structure, but far more restricted access — which is why most financial plans use both rather than treating them as competing products.
What is the Two-Pot Retirement System?
Since 1 September 2024, retirement funds have generally been structured around three components.
Primarily reflects retirement savings accumulated before the Two-Pot system began, subject to the rules that applied to your fund at the time.
Allows limited access before retirement — generally one withdrawal per tax year, with a minimum of R2,000, taxed at your marginal income-tax rate.
Intended to remain preserved for retirement rather than being withdrawn when you leave a job or change funds.
Money withdrawn today is money that's no longer invested and compounding toward your future retirement. That doesn't mean a withdrawal is always wrong — it means the tax cost and the long-term opportunity cost should be part of the decision, not an afterthought.
So what should I actually look at when reviewing a fund?
You don't need to memorise every investment term. When you're looking at a fund, statement or portfolio, these questions are far more useful:
A practical investment checklist
- What am I actually invested in, past the product name?
- Which asset classes, sectors and regions am I exposed to?
- Is the fund active or passive — and if active, what's the manager's philosophy and process?
- What's the appropriate benchmark, and how has it performed against it?
- What does it cost me in total, not just TER?
- What level of risk and volatility am I taking on?
- What tax applies, given how and where it's held?
- How does this fit with everything else I already own?
A fund can look good on its own and still be unnecessary in your portfolio
Imagine you find a fund with an attractive historical return, a respected manager and reasonable fees. That doesn't necessarily mean adding it improves your portfolio — you may already have substantial exposure to the same companies, sectors or asset classes elsewhere. The fund itself may be perfectly reasonable, and still unnecessary in the context of what you already own.
The question isn't just “is this a good fund?” It's “what role does this fund play in the portfolio?”
1. An ETF and an index fund are not the same thing — one describes the structure, the other the strategy.
2. A return means very little without its benchmark, risk and costs attached.
3. TER matters, but it's only one part of the total cost of investing.
4. Tax can materially change the return you actually keep.
5. No investment exists in isolation — your goals, time horizon and existing portfolio matter just as much as the fund itself.
Want to understand what you already own?
Your investment statement may hold dozens of terms and figures, but the important questions are simple: what do you own, why do you own it, what does it cost, what risks are you taking, what tax applies, and how does it fit into the rest of your financial plan? We can help you work through those questions and see how your investments fit together.
