Start with the mechanism. Risk and return move together because the market prices uncertainty. An investment that promises a steady, modest outcome does not need to pay you much for holding it, because there is little to worry about. An investment whose outcome swings widely, what analysts call volatility (how much a price moves up and down over a period), has to offer a higher average return to attract anyone at all. Nobody takes on a bumpier ride for free. So a higher headline return is not a reward for being clever. It is compensation for a risk you are agreeing to carry, whether or not you have priced it correctly in your head.
Here is where the made-up numbers help. Say Stock A returns a steady 9% a year, with little variation. Stock B averages 18% a year over a ten-year stretch, which looks twice as attractive on a poster. But Stock B's ten-year run includes one year at minus 40%. Put ₦1,000,000 into Stock B the year before that drop and you are looking at ₦600,000 the year after. To get back to ₦1,000,000 from there, you do not need a 40% gain. You need a 67% gain, because the loss and the recovery are measured off different bases. That arithmetic, not the average return, is the part beginners skip.
Many people entering the market do the opposite of what the numbers require. They anchor on the 18% average, because it is the number usually quoted, and treat the minus 40% year as a footnote, if they consider it at all. In practice the sequence matters more than the average. A beginner who buys Stock B at its peak and meets the minus 40% year first may find it much harder not to sell at the bottom than one who meets it fifth, after some gains have built a cushion. Both investors are holding the same stock with the same long-run average. Their experience of risk is completely different, and it is often the drawdown, not the average, that decides whether they stay in the market long enough to see the recovery.
This is also why "higher return" and "better return" are not the same claim. A fund or stock that returns 18% with a 40% drawdown has taken on a specific kind of risk: the risk of a large, sudden fall that tests whether you sell at the wrong time. A beginner comparing two options on headline return alone, without asking how each one behaves in a bad year, is comparing incomplete information. The return is published. The drawdown history is often harder to find, and a reader should notice that gap rather than assume the quiet number means a quiet investment.
This matters more for retail investors in Nigeria, Ghana and South Africa than the textbook version suggests, because local market conditions already supply plenty of downside without any help from a badly timed entry. Naira and cedi depreciation, interest rate shifts from the Central Bank of Nigeria or the Bank of Ghana, and equity market swings on the JSE or the NGX can all compress into the same calendar year. A stock that looks merely volatile in isolation can produce a sharper fall than its own history suggests once a currency move or a rate decision lands in the same period. None of this is a reason to expect the worst by default. It is a reason to treat a quoted return as half the story rather than the whole of it.
None of the figures above come from a real company or a published return series. They are illustrative, built to show the mechanics of drawdown and recovery, and nothing here should be read as a claim about any specific listed stock's actual history. A reader who wants the real version of this exercise needs the underlying price data for a given stock or fund, including its worst calendar year, not just its average. That data is not something this piece supplies, and a beginner comparing two real options should go looking for it rather than relying on the headline return quoted in an advert or a chart caption.
What the numbers do show, consistently, is that the size of a possible fall deserves at least as much attention as the size of a possible gain. Return gets the marketing. Drawdown gets the silence. A beginner who reads both before buying is already ahead of one who reads only the first.
