How Many Funds Should You Hold in a R10 Million Portfolio?

Fund count is the total number of unit trusts, ETFs, or collective investment schemes you hold across all your investment wrappers at any given time. For a R10 million portfolio, the right number is typically between four and eight, spread across the major asset classes without duplicating exposure. Holding more than ten rarely adds meaningful diversification. It usually adds cost and complexity instead.

The answer depends less on the rand value of your portfolio and more on whether your holdings genuinely cover different asset classes, geographies, and risk profiles. A single well-constructed balanced fund can achieve what twelve poorly chosen funds cannot.

The sections below explain fund overlap, the South African wrapper structure that creates accidental duplication, Regulation 28 constraints, and what a sensibly constructed R10 million portfolio actually looks like in practice. If you’re also thinking about the broader asset allocation question, start with what a R10 million portfolio should look like.

Why More Funds Does Not Mean More Diversification

Adding funds to a portfolio does not automatically reduce risk. True diversification comes from holding assets that behave differently under the same market conditions, not from increasing the number of line items on your statement.

This is one of the most persistent mistakes I see in portfolio construction. Many investors equate a longer list of funds with a broader spread of risk. In practice, two South African equity funds from different asset managers often hold the same twenty or thirty underlying shares. Naspers, FirstRand, BHP Group, Anglo American Platinum: these names appear in almost every JSE-exposed equity fund. If you hold three local equity funds, you may think you have spread your risk across three separate portfolios. You have not. You have concentrated it three times in the same handful of counters.

The question to ask is not “how many funds do I own?” but “how many genuinely distinct asset classes am I exposed to?” A well-diversified R10 million portfolio needs coverage across South African equities, global equities, local bonds, global bonds or alternatives, and cash or money market instruments. Five asset classes. You do not need five funds per class to achieve that.

Fund count also interacts with your ability to monitor what you own. A portfolio with twelve funds is harder to rebalance, harder to review, and harder to understand at a glance. When markets move sharply, complexity becomes a liability.

Here is the practical test. Take any two equity funds you hold and look at their top ten holdings. If the overlap is more than 50%, you are paying two sets of fees for one effective portfolio. Consolidating into a single fund of higher quality reduces cost without reducing exposure. For a deeper look at where concentration risk actually lives in a large portfolio, the article on risk concentration and how to fix it covers the mechanics in full.

What Fund Overlap Is and Why It Quietly Erodes a Portfolio

Fund overlap occurs when two or more funds in a portfolio hold the same underlying securities, so you pay multiple layers of fees for exposure you already have. The more overlap, the higher the effective cost relative to the diversification benefit you receive.

This matters far more than most investors realise. Many unit trusts are described as different products: one labelled “growth”, another “balanced”, a third “flexible”. But if each allocates 40% to South African equities and 30% to global equities through similar indices or the same offshore feeder funds, their underlying holdings converge. You are not buying safety by owning more of them. You are buying the illusion of safety at a higher cost.

Fund overlap is particularly common when investors hold the South African version and the rand-denominated feeder version of the same underlying global fund. Some locally registered funds invest directly into an offshore parent fund. Holding both is not diversification. It is duplication with a currency translation layer attached.

The overlap problem compounds over time. If you have added funds gradually over fifteen years, as circumstances or advisers changed, the resulting portfolio may contain eight or ten funds that effectively replicate two or three distinct investment positions. Each review cycle, the fees accumulate while the genuine diversification stays flat.

Fixing overlap usually means consolidating, which raises a tax question in your own-name investments. But within a living annuity or preservation fund, switching between funds does not trigger a capital gains tax event, which makes consolidation considerably simpler inside those wrappers.

Genuine diversification across geographies also requires deliberate currency exposure, not just funds with “global” in their name that remain rand-denominated. The article on why currency diversification matters explains the distinction between real offshore exposure and local funds with offshore allocations.

What Is an Appropriate Number of Holdings for a Global Allocation?

For a globally diversified allocation within a South African retirement portfolio, two to four funds typically cover the necessary ground: one broad global equity fund, one local equity or balanced fund, one local bond or multi-asset income fund, and optionally one global bond or alternative asset fund.

Regulation 28 is the rule that governs how retirement savings in South Africa can be allocated across asset classes. It applies to retirement annuities, pension funds, provident funds, and preservation funds. Under Regulation 28, a maximum of 45% of a retirement fund may be invested offshore, including Africa ex-South Africa, and no more than 10% in a single unlisted asset class. This constraint shapes the fund count decision for retirement-wrapper assets directly: if 45% is the offshore ceiling, you need enough offshore funds to diversify that portion meaningfully, but not so many that you create overlap at the global level too.

Outside retirement wrappers, in investments held in your own name, you have access to the full annual foreign capital allowance, currently R10 million per year for individuals with a tax clearance, and you are not bound by Regulation 28. This means you can and often should hold more concentrated offshore exposure in own-name accounts to complement the constrained allocation inside retirement funds.

For investors following Shari’ah-compliant principles, the fund universe is smaller. Fewer South African asset managers offer fully Shari’ah-screened global equity, sukuk, or alternative funds. In practice, a Shari’ah-compliant portfolio may need to work with two or three funds where a conventional portfolio might use four, accepting slightly less granularity in exchange for staying within the screening requirements. The underlying diversification can still be adequate if the funds chosen cover different geographies and risk profiles.

For a full treatment of how to structure the offshore portion of a large portfolio, the articles on offshore investing for South African retirees and a practical guide to investing offshore from South Africa set out the mechanics in detail.

Counting Funds Correctly Across All Your Wrappers

The critical mistake many investors make is counting funds within a single account, rather than across all their investment wrappers together. If you hold three funds inside your living annuity, two inside a preservation fund, and four in an investment account in your own name, you do not have three funds. You have nine. The question of how many funds should I hold must be answered at the total-portfolio level.

Here is why this matters for a R10 million portfolio. Suppose R6 million sits in a living annuity invested in a balanced fund, a local equity fund, and a global feeder fund. R2 million sits in a preservation fund also holding a balanced fund and a local equity fund. R2 million sits in your own name in a local equity ISA and a money market fund. At the account level, everything looks contained. At the portfolio level, you are holding two balanced funds that overlap substantially, two local equity funds that overlap almost completely, and a global feeder fund alongside an offshore balanced fund that holds many of the same underlying positions. The effective diversification may be no better than two or three genuinely distinct funds would provide, but you are paying fees on nine.

The arithmetic: if the nine funds carry a blended total expense ratio of 1.4% per year on R10 million, the annual cost is R140,000. Consolidating to five well-chosen funds with a blended TER of 0.9% saves R50,000 per year. Over ten years, at 8% average growth, that saving compounds to roughly R750,000.

Switching funds inside a living annuity or preservation fund carries no capital gains tax. Switching inside own-name investments does. If consolidating your own-name funds means selling appreciated units, the CGT event needs to be modelled before you act. This is where the wrapper structure matters. The articles on retirement annuity versus provident fund and smart income choices for South African retirees explain the tax treatment of each wrapper in more detail.

How Many Funds You Actually Need: A Scenario Comparison

The table below summarises four common portfolio configurations for a South African investor with R10 million. It shows what each approach actually delivers, what it costs, and where it falls short. TER figures are illustrative and represent a reasonable mid-market estimate for each scenario.

The lesson is straightforward. Moving from a single fund to four covers meaningful new ground. Moving from four to twelve typically adds cost without adding asset-class coverage. The high-fee objection some investors raise about employer retirement plans is real, but the answer is not to avoid participating. It is to choose fewer, lower-cost funds within the plan rather than layering in every option available.

For investors uncertain whether their existing fund selection is working for them, the article on whether you need a financial adviser at this level addresses when independent oversight genuinely adds value.

How Much Cash to Hold Alongside Your Funds

The right cash holding depends on two distinct needs: emergency liquidity and an opportunity buffer. These are not the same thing, and conflating them leads to either too little available when you need it or too much sitting idle.

For emergency reserves, the standard guidance is three to six months of living expenses held in a money market fund or high-interest bank account that you can access within days. For a retired investor drawing R60,000 per month from a living annuity, that means R180,000 to R360,000 in accessible cash. This should sit outside your retirement wrappers, in your own name, where there is no restriction on withdrawal.

An opportunity buffer is different. Some investors with large portfolios choose to hold an additional 5% to 10% in cash or near-cash instruments, available to deploy when equity markets fall sharply or when a property or private equity opportunity arises. On a R10 million portfolio, that is R500,000 to R1 million. The objection that cash guarantees a loss in real terms after inflation is legitimate. Money market returns in South Africa have historically tracked closely to the repo rate, which at times falls meaningfully below CPI. Holding cash as a permanent position is not a strategy. Holding it as a temporary buffer with a clear deployment trigger is.

Do not confuse money market funds with individual bonds. A money market fund holds a diversified basket of short-dated instruments and is priced daily with very low volatility. An individual bond carries duration risk: its market value moves inversely with interest rates. For a fuller picture of how inflation quietly works against fixed holdings over time, the article on how inflation erodes retirement savings is worth reading.

How Many Index Funds Does Someone Actually Need?

For a well-diversified passive portfolio, three index funds are usually sufficient: a broad South African equity index fund, a global equity index fund, and a local bond or money market index fund. Adding a fourth for specific offshore exposure or property is reasonable. Beyond four, you are likely creating too many unit trusts without meaningfully changing your risk profile.

Investors frequently ask whether the specific number of index funds affects long-term performance. In most cases, it does not, beyond a certain minimum. What matters is the asset-class coverage, the cost, and whether the index construction creates unintended concentration. The JSE is a heavily concentrated market: the top ten shares account for a large share of the FTSE/JSE All Share Index. Holding three South African equity index funds does not solve that concentration. It triples your exposure to the same companies at three times the fees.

The active versus passive debate is real, but the choice is not binary. Many large South African retirement portfolios use an index fund for the offshore equity allocation, where costs and currency friction matter most, alongside a carefully selected active manager for local equities, where the market is less efficient and active managers have more opportunity to add value. This hybrid approach typically needs no more than four to six funds in total.

Where Shari’ah-compliant investing is a requirement, the passive universe is smaller still, and two or three well-chosen Shari’ah-screened funds may cover the full allocation without the need for more. For currency-hedged ETF options and their role in a large portfolio, the articles on currency diversification ETFs and dividend investing for retirement income offer useful context.

Frequently Asked Questions

How many funds should be held in a portfolio?

For a South African portfolio of R5 million to R20 million, four to eight funds is the range that covers the major asset classes without creating costly duplication. A single well-constructed balanced fund can serve as a complete portfolio in its own right, though most investors at this level benefit from adding at least one dedicated offshore fund to manage Regulation 28 ceiling constraints.

What is an appropriate number of holdings for a global investment allocation?

Two to four funds typically cover a global allocation adequately: a broad global equity fund, a global bond or multi-asset fund, and optionally a global property or alternatives fund. Holding more than four global funds almost always creates overlap at the underlying security level, particularly among funds tracking similar global indices.

How many index funds does someone need to own?

Three index funds cover the core asset classes for a passive strategy: a South African equity index, a global equity index, and a local bond or money market index. A fourth fund targeting a specific geography or sector is reasonable. Holding more than four or five index funds rarely changes the effective diversification of the portfolio.

How much cash should be held as emergency reserves?

Three to six months of living expenses, held in an accessible money market fund or bank account in your own name. For a retiree drawing R60,000 per month, that is R180,000 to R360,000. This cash should not sit inside a retirement wrapper, where access is restricted.

How much cash should wealthy investors keep available for opportunities?

An opportunity buffer of 5% to 10% of the total portfolio is a reasonable ceiling, held in a money market fund rather than a bank account to earn a market-related return while remaining liquid. On a R10 million portfolio, that is R500,000 to R1 million. Holding more than this in cash as a permanent position creates a meaningful drag against inflation over time.

The Right Number of Funds Is the Fewest That Cover Your Actual Needs

For most South African investors with a R10 million portfolio, four to eight funds held across all wrappers is the right answer to how many funds should I hold. More than eight usually means duplication, higher fees, and a portfolio that is harder to manage without adding real diversification.

Review your holdings at the total-portfolio level, not account by account. Flag overlap. Count the asset classes you actually cover, not the number of line items on your statement.
