The active vs passive investing debate is usually framed as a contest with a winner. Either you back a fund manager to outsmart the market, or you accept the market’s return at the lowest possible cost by tracking an index. Put that way, the long-run evidence is fairly one-sided: after fees, most active managers fail to beat their benchmark over a full market cycle, and South Africa is no exception — S&P Dow Jones Indices’ SPIVA scorecard shows roughly three-quarters of local active funds underperforming over ten years.
But “just buy the index” is a cleaner answer in the United States than it is in Johannesburg. The JSE is unusually concentrated, a handful of shares can dominate a market-cap-weighted index, and there are segments where skilled active management has genuinely earned its keep. So the useful question isn’t which camp is right — it’s where each approach earns its place, and what you’re paying for the privilege. This piece works through both, and pairs naturally with our guide to ETFs in South Africa if you want the mechanics of passive investing in more detail.
Key Definitions
Active management
An approach where a fund manager makes deliberate decisions about which securities to hold, aiming to beat a benchmark index. It carries higher fees to pay for the research and management.
Passive (index) investing
An approach that simply tracks a market index — such as the S&P 500 or a JSE index — accepting the market return at a very low cost rather than trying to beat it. Usually accessed through index funds or ETFs.
Total Investment Charge (TIC)
The all-in annual cost of an investment, including the fund’s management fee (TER), trading costs, and any performance fees. The single most useful number when comparing funds, because it captures what actually comes off your return.
Closet indexer
An active fund that charges active fees but holds a portfolio so close to its benchmark that it can never meaningfully outperform it. The worst of both worlds — active cost, passive return.
What the Evidence Actually Says
The single most useful source in this debate is the SPIVA South Africa scorecard, published twice a year by S&P Dow Jones Indices. It does something most performance studies don’t: it compares active funds against the right benchmark, and it corrects for survivorship — the funds that quietly closed along the way. That correction matters more than almost anything else here.
The headline is sobering for the active industry. Across categories, around 75% of South African active funds underperformed their benchmark over the most recent ten-year period. Underperformance tends to get worse the longer you measure, and the survivorship numbers are the quiet scandal: over a recent ten-year window, roughly 40% of South Africa equity funds were merged or liquidated. The funds with poor records don’t usually stay open to embarrass anyone — they disappear, which flatters every “look how well active did” chart built only from the survivors.
There’s a second, subtler problem: persistence. Even the managers who do beat the market in one period rarely repeat it in the next. Some of that outperformance is skill; a great deal of it is luck, and luck doesn’t compound. The practical consequence is that picking next decade’s winning fund in advance is genuinely hard — much harder than the marketing brochures imply.
Why South Africa Isn’t the United States
If the data is that one-sided, why not simply index everything and be done with it? Because the South African market has a feature that complicates the textbook answer: concentration.
A market-cap-weighted JSE index is dominated by a small number of very large shares. For years a single counter and its offshore parent — effectively a proxy for one Chinese technology holding — could swing the whole index, and the top ten shares still carry an outsized weight. Buy a naive cap-weighted tracker and you may be taking a far more concentrated bet than you realise, in a handful of names you’d never deliberately overweight. This is precisely why the index providers themselves publish capped versions of their benchmarks — to keep any one share from distorting the whole.
That concentration cuts two ways. It means passive investors in SA need to look carefully at which index they’re tracking. And it leaves more room for a skilled active manager to add value by sidestepping the concentration risk — which is part of why the local picture is genuinely more mixed than the US. In 2024, for instance, the majority of South Africa equity managers actually beat their benchmark for the year. The catch is that the same managers, measured over five and ten years, still underperformed roughly three-quarters to nine-tenths of the time. A good year is not a track record.
The lesson isn’t “active wins in SA”. It’s that market efficiency varies by segment, and a thoughtful answer treats each segment on its merits rather than applying one rule everywhere.
The Real Enemy Is Cost — and Closet Indexing
Strip the debate back and most of it comes down to fees. Active management isn’t a bad idea because managers are unskilled — it’s a hard idea because the fee starts you in a hole you have to climb out of every single year. A passive ETF might cost you a fraction of a percent a year; an active fund’s all-in cost, once you include the management fee, trading, and any performance fee, is often well over 1%. That gap is the hurdle the manager has to clear before you see a cent of outperformance.
And it compounds — ruthlessly. Consider two identical R10 million portfolios over 20 years, both earning 8% a year before fees, where one simply pays 0.5% more in annual costs. That half a percent doesn’t cost you 0.5%. On these illustrative assumptions it costs roughly R4 million by year 20 — because the fee is deducted from a growing base, year after year, and the money it skims never gets to compound. The longer the horizon, the larger the leak.
Which brings us to the most expensive mistake of all: the closet indexer. This is an active fund that charges active fees but hugs its benchmark so closely it can’t meaningfully outperform. You pay for skill and receive the index minus costs — the worst of both worlds. A large slice of disappointing active performance isn’t bold bets gone wrong; it’s expensive funds that were never really active to begin with.
| Dimension | Passive (Index) | Active |
|---|---|---|
| Cost | Low — often a fraction of a percent | Higher — typically 1%+ all-in |
| Long-run record | Reliably captures the market return | Most underperform over 10 years (SPIVA) |
| Concentration risk | Inherits the index — can be high on the JSE | Can be managed deliberately |
| Chance to outperform | None by design — you get the benchmark | Possible, but hard to predict in advance |
| Best suited to | Efficient markets (US large-cap, global bonds) | Concentrated or inefficient segments |
Where Each Approach Earns Its Place
Rather than crown a winner, it’s more useful to ask, segment by segment, how efficient the market is and whether an active fee can plausibly be justified. That produces a far more practical map than any blanket rule.
| Market segment | Sensible default | Why |
|---|---|---|
| US / global large-cap | Passive | Highly efficient and well-researched; active rarely justifies its fee here |
| Global bonds | Mostly passive | Low dispersion; cost discipline matters more than manager flair |
| SA equity | Selective active | Concentrated index; skilled managers can manage that risk — but watch for closet indexers |
| Emerging markets / niche | Active worth considering | Less efficient, more dispersion — more room for genuine skill to show |
| SA bonds | Either — cost-led | Active has a reasonable record in some categories; let total cost decide |
How We Think About It at Henceforward
We’re not in either ideological camp. We use low-cost index funds and ETFs as the default wherever a market is efficient enough that paying for active management is hard to justify — global developed equity and global bonds being the obvious examples. We’re willing to use active management where the evidence supports it: concentrated or less-efficient segments like South African equity and certain emerging or specialist mandates, where a genuinely skilled manager can add more than they cost.
The non-negotiable in both cases is cost. We quantify the fee drag in rand terms over a client’s actual horizon, because a number like “1%” feels small until you see it as a seven-figure leak over a few decades. And when we do use active managers, we screen hard for conviction — a real, repeatable process — rather than a closet indexer charging active fees for benchmark-hugging returns. As a fee-only firm, we earn nothing from the products we recommend, which means we can be genuinely indifferent between active and passive and choose purely on merit. That independence is the whole point.
What This Means for Your Portfolio
A few practical takeaways follow from all of this. Start with cost: know your Total Investment Charge across every fund you hold, because that single number explains most of the long-run difference between portfolios. Default to passive in efficient markets — for most South Africans, broad global and US large-cap exposure is better bought cheaply than paid for actively, a point we develop in our offshore investing guide.
Reserve active management for where it can actually earn its fee, and when you use it, demand genuine conviction rather than a benchmark-hugger in disguise. Don’t confuse a good year with skill, or a compelling story with a track record. And if your instinct is to pick individual shares yourself, go in with your eyes open about the odds — we wrote candidly about that in our piece on DIY investing, and the same discipline around cost, concentration, and investment risk applies whether you’re choosing funds or stocks.
Frequently Asked Questions
Is passive investing always better in South Africa?
Not always. Over long horizons most active SA funds underperform low-cost index trackers after fees, so passive is a strong default. But the JSE's concentration means the index you track matters, and in less-efficient segments a skilled active manager can add value. The honest answer is segment-by-segment, not one-size-fits-all.
Do any active managers actually beat the index?
Yes — some do, and in certain years a majority of SA equity managers have. The difficulty is twofold: outperformance rarely persists from one period to the next, and survivorship flatters the records of the funds that are still open. Identifying tomorrow's winner in advance is much harder than the marketing suggests.
What is a reasonable cost for a passive ETF?
Broad-market index ETFs typically cost a fraction of a percent a year, versus roughly 1.5% or more all-in for many active funds. The number to compare is the Total Investment Charge (TIC), which captures management fees, trading costs, and performance fees together — not just the headline management fee.
Is the JSE too concentrated to index?
It's concentrated enough that the choice of index matters. A naive market-cap-weighted tracker can leave you heavily exposed to a few large shares. Capped index versions exist precisely to manage this, and it's one reason selective active management has a stronger case in SA equity than in, say, US large-cap.
Should I use active or passive for my retirement fund?
Both can sit inside a Regulation 28-compliant retirement portfolio. The deciding factors are the same as anywhere: market efficiency by segment and total cost over your time horizon. Given the multi-decade horizon of retirement savings, keeping costs low is especially powerful because the fee drag compounds for longer.
The Bottom Line
Active versus passive was never really a battle of philosophies. It’s a question about cost and market efficiency, answered one segment at a time. The long-run evidence makes low-cost passive a powerful default — especially in efficient global markets, and especially over the long horizons that matter most to retirement savers.
South Africa adds a genuine wrinkle: a concentrated index that rewards thinking carefully about what you track, and leaves room for skilled active management to earn its place in the right segments. The throughline in all of it is fees and intellectual honesty — knowing what you pay, and not mistaking luck or a strong story for durable skill.
Get the cost question right and you’ve won most of the battle before you’ve chosen a single fund. The rest is matching the approach to the market, and being honest about where an active fee is genuinely buying you something.
