Individual shares or funds: what should a beginner buy?

What you are actually choosing between

Buying an individual share means owning a piece of one company. Your outcome depends on that company - its management, its industry, its debt, its competitors, and any single event that hits it.

Buying a fund - an ETF or unit trust - means owning a small piece of many companies at once. One company failing barely registers. Our guide to what an ETF is and how to buy one covers the mechanics.

The difference is not sophistication. It is how much of your outcome rests on things you cannot control or foresee.

What concentration actually does

The case for funds rests on something less obvious than "diversification is good".

Across long periods and many markets, the returns of a whole index are typically driven by a relatively small minority of its companies. A large share of listed companies underperform cash over their lifetimes, and a small number of enormous winners carry the average.

The implication is uncomfortable for stock pickers. If you hold five or ten shares, the odds that you own a meaningful share of the big winners are low - and missing them means trailing the index even if none of your picks fail. Owning the whole index guarantees you own every winner, along with everything else.

What the professional record shows

Most actively managed funds fail to beat their benchmark index consistently over long periods, after fees. This is documented repeatedly across markets and decades.

These are full-time professionals with research teams, direct access to management, and information you will never see. If they struggle to beat the index reliably, it is worth being honest about the odds facing someone researching in the evenings after work.

This is not an argument that markets are unbeatable. Some people do beat them. It is an argument about the base rate you are starting from, and about what happens to the average person who tries.

Buying an index fund is not admitting you cannot pick winners. It is recognising that you do not need to.

The honest case for individual shares

Funds are not automatically correct, and the arguments on the other side are real:

• Engagement. Owning a company you understand makes investing tangible. Many people who now invest seriously started because a single share made them care.
• Learning. Reading annual reports and following a company through good and bad years teaches you things no amount of theory will - including how you actually behave when a holding falls 30%.
• No annual fee. A share you hold has no TER. Over long periods with a genuinely long holding, that is a real saving.
• Control. You choose exactly what you own, which matters if you want to exclude certain industries or express a specific view.
• Tax timing. You control when you realise gains, since you decide when to sell - see how investment tax works in South Africa.

How many shares does diversification actually take?

Conventional guidance suggests you need at least 20 to 30 holdings across different sectors before company-specific risk is meaningfully reduced. And that is only the first layer - 25 JSE-listed shares still leaves you concentrated in one small economy.

Now consider the workload. Twenty-five companies means twenty-five annual reports, fifty sets of results a year, and continuous monitoring. That is close to a part-time job, done properly. A single global index fund achieves broader diversification in one transaction that takes ninety seconds. See how to build a diversified portfolio.

Core and satellite: the sensible compromise

You do not have to choose one. The approach most people land on eventually:

• The core - 90-95%. Broad, low-cost index funds covering local and global markets. This is your retirement, your future, the money that must not be experimented with.
• The satellites - 5-10%. Individual shares or specific themes. Money you can afford to lose entirely without changing your plans.

This gives you almost all of the diversification and cost efficiency, plus a genuine outlet for curiosity. Your learning happens with real money and real consequences - which is the only way it sticks - while the bulk of your wealth stays sensibly invested.

It also produces a valuable experiment. Track your satellite performance honestly against your core over five years. If you consistently beat it, you have learned something genuinely useful about yourself. If you do not - which is the more common outcome - you have learned that at a cost of 5% of your portfolio rather than all of it.

Where beginners actually go wrong

The failure mode is rarely "bought shares instead of a fund". It is usually one of these:

• Buying on a tip. Someone confident on social media is not research. They do not know your finances and often own the thing already.
• Mistaking familiarity for analysis. Knowing a brand tells you nothing about whether the share is reasonably priced.
• Putting everything into two or three names. Enough concentration for a disaster, not enough for a strategy.
• Selling the losers, holding the winners' story. Emotional trading is where most of the damage happens - see common beginner mistakes.
• Trading too often. Every round trip pays brokerage and potentially triggers tax on gains.

Note that a fund investor structurally avoids most of these, simply by having fewer opportunities to act.

The straightforward answer

If you are starting out, put your core in a broad, low-cost index fund - ideally inside a tax-free savings account - and fund it with a monthly debit order. That single decision puts you ahead of a large share of investors, requires almost no ongoing work, and does not depend on you being right about anything.

Then, if individual companies interest you, carve out a small satellite portion and learn properly. Read the annual reports. Write down your reasoning. Track your results honestly.

What you should not do is skip the core. Curiosity about a company is a fine reason to research it. It is not a reason to put your retirement into it.

Learn what you own

Whichever mix you choose, understanding it is what makes you a better investor.

It is an educational tool - it explains, you decide.

Frequently asked questions

Should beginners buy individual stocks or index funds?

For the core of a portfolio, index funds suit most beginners better. They spread money across hundreds of companies in one purchase, cost very little, and require no ongoing analysis. Individual shares can be added later with money you can afford to lose while you learn what research actually involves.

How many shares do I need for a diversified portfolio?

Conventional guidance suggests at least 20 to 30 holdings across different sectors before company-specific risk is meaningfully reduced - and even then you are still concentrated in one country unless you diversify globally. A single broad index fund achieves far more diversification in one transaction.

Do professional fund managers beat the market?

Most do not, consistently, over long periods after fees. This is well documented across many markets and is not a criticism of their skill - it reflects how difficult the task is and how much fees matter. It is the central argument for low-cost index investing.

What is core and satellite investing?

Holding the large majority of your portfolio in broad, low-cost index funds - the core - and a small portion, often 5 to 10%, in individual shares or specific themes - the satellites. It keeps most of your money diversified while leaving room to learn from real decisions with real money.

Is it wrong to want to pick shares?

Not at all. Picking shares is how many people become genuinely engaged with investing, and engagement is valuable. The mistake is putting the money you cannot afford to lose into a handful of companies before you understand what you own. Structure it so learning is affordable.
