How Rand-Cost Averaging Could Help You

“It is better to be roughly right than precisely wrong.” (John Maynard Keynes)

John Maynard Keynes, one of the greatest economists and risk-taking investors around, strongly advised putting investing on ‘autopilot’, and then going out and enjoying your life!

The basics

Investing can be tricky, even for seasoned professionals who try to buy and sell at the right moment.

Rand-Cost Averaging offers a solution that allows you to easily navigate uncertain markets by automating regular investments. With Rand-Cost Averaging, you invest the same amount in an investment at consistent intervals, regardless of price fluctuations. This strategy may lower the average cost per share or unit trust. This can safeguard you from market volatility and remove the need to time your purchases perfectly.

Who’s it good for?

This strategy is excellent for inexperienced investors who are risk-averse and are scared to wade in. It could be a great way to start investing.

But it’s also a good way of reining in impulsive risk takers. A risky approach can get you interested in edgy companies which may (or may not) be the market’s next lightning bolt. Rand-Cost Averaging imposes discipline and removes the temptation to chase the next big thing.

A simple example

Imagine you have R600 that you want to invest in a unit trust over 6 months, instead of investing it all at once.

Total Investment: R600 over 6 months

Total units bought: 2 + 2.5 + 3.33 + 5 + 2.5 + 2 = 17.33 units

Average price per unit: R34.62

If you had invested all R600 in January when the unit price was R50, you would have bought only 12 units (R600 ÷ R 50 = 12).
By using Rand-Cost Averaging, you bought 17.33 units at an average price of R34.62 per unit, a much lower price than if you had bought everything upfront.
Of course, you could have lucked out and bought the units in April, when they cost just R20. But this is a gambler’s mentality, not an investor’s.

Life offers no guarantees

Rand-Cost Averaging is great, but there is one important caveat. The entire concept assumes that over time, markets tend to rise.

While this is generally true for most sound investments, you certainly don’t want to consistently allocate money towards an investment that’s consistently underperforming. If you’re buying at a low point month after month and not seeing a return, then you may be sinking money into an investment that is not likely to make gains. That’s a position that no investor wants to be in, so think twice about using a consistent approach in this case.

Set it and forget it

Before you start setting up debit orders, you’ll need to find out how much you can afford to dedicate to your chosen investment. If you’re investing for retirement, there is no one-size-fits-all answer to how much you should save for retirement, but academic studies based on historical data can give you a ballpark figure. We’d advise aiming to save around 15% of your net income (i.e. after tax) if you’re early in your career.

Let’s sum up the benefits

Lower costs: Rand-Cost Averaging can help reduce the average price paid for investments over time.
Regular investing: It builds a practice of consistent investing, something that’s essential for long-term wealth growth.
No speculation: By removing the pressure of market timing, Rand-Cost Averaging ensures you’re always in the market.
Emotional control: It tempers the urge to make reckless decisions that could harm your portfolio.
Risk mitigation: It helps prevent large, ill-timed lump sum investments.
Universal appeal: Both beginners and veterans benefit from the disciplined, emotion-free approach of Rand-Cost Averaging.

Is there ever a place for lump sum investing?

Of course there is. You may have a large sum to invest from the sale of a business or an inheritance for instance. Ultimately, the best approach depends on your financial situation, risk tolerance, and investment goals. To achieve benefits similar to those of Rand-Cost Averaging you might want to consider making your investment in phases.

But there may be an opportunity cost to holding part of the lump sum in a cash-related investment instead of diving straight into equity.

The bottom line

In many cases, the consistency that Rand-Cost Averaging brings to your financial life is an asset in itself. Please do call us if you’d like to discuss any of the above.

When Risk No Longer Feels Risky

After years of market turbulence followed by surprisingly resilient recoveries, many investors are asking an unexpected question: “Am I being too cautious?”
Let’s look at how recent experience shapes our perception of risk, why discipline still matters, and the role thoughtful financial advice plays in keeping emotions from driving investment decisions.

Why Markets Keep Finding Their Way Back to the Same Place

This year, just about everything that could go wrong has gone wrong. But despite the turmoil markets have shown remarkable resilience. Time and again, investors have been confronted with events that seemed destined to derail global growth, only for fundamentals to reassert themselves. As wars, technology, and economic policy continue to pull markets in different directions, one question remains: why do markets keep ending up in almost exactly the same place?

While Wall Street Wobbles, South Africa Gains Momentum

Since the year dot, narratives have driven investor sentiment. June’s narrative was largely positive for South Africa as investors uprated our investment potential, but it was decidedly rocky for US investors, with chipmakers leading stock markets to heady highs before driving them down to disconcerting lows.

What Does Financial Planning Look Like if You Don’t Have Kids?

For generations, financial planning followed a familiar script: build a career, buy a home, raise a family and, eventually, pass wealth on to the next generation. While that path still resonates with many, modern lives are far more diverse. The reasons for not having kids may differ, but the financial question is often the same: if your wealth is not destined for children, how can it best enrich your life, reflect your values and leave a meaningful legacy long after you are gone?
