maximum drawdown
Maximum Drawdown is the biggest drop your investment ever took from its highest point to its lowest, before it recovered.
In plain English
Here is the surprising part. Two investments can end the year with exactly the same profit, and yet one of them put its owner through far more sleepless nights than the other. That difference in suffering has a name, and it is maximum drawdown.
Maximum drawdown measures the worst fall an investment suffered from its peak value to its lowest point afterwards, before it climbed back up. It does not care about the final score. It cares about how bad the middle got.
Say a Lagos investor puts money into a growth focused mutual fund. The fund grows nicely for two years, then a market shock hits and it falls by 40 per cent before recovering over the following year and finishing even higher than before. That 40 per cent fall is the maximum drawdown, and it is the number that tells you what it actually felt like to hold that investment, more than what you gained at the end.
This matters a lot for anyone sending money home or building a retirement pot slowly. A fund manager in London might show you a beautiful ten year average return, but if the fund lost 55 per cent at some point along the way, someone who needed to withdraw money during that dip would have been in real trouble, average return or not.
Drawdown is really a measure of pain tolerance. Two funds returning 12 per cent a year can have wildly different drawdowns, one falling 15 per cent in its worst year and the other falling 45 per cent. If you cannot stomach the 45 per cent version, no amount of long term maths will keep you calm enough to stay invested through it.
An investor's portfolio grows from ₦2,000,000 to ₦3,000,000, then a market crash takes it down to ₦1,800,000 before it eventually recovers and grows further. The maximum drawdown here is the fall from the ₦3,000,000 peak to the ₦1,800,000 low, which is a 40 per cent drawdown, even though the portfolio later went on to grow beyond ₦3,000,000.
Questions people ask
Is a smaller maximum drawdown always better?
Generally yes, because it means the investment gave you a gentler ride, but a very low drawdown often comes with lower long term returns too. The point of checking it is not to chase the smallest number, but to make sure you can actually live with the falls an investment has shown in the past before you commit your money to it.
How is maximum drawdown different from just losing money?
Losing money is any drop at all, but maximum drawdown specifically measures the single largest fall from a peak to the lowest point that followed it, before recovery. It captures the worst stretch in the entire history you are looking at, rather than every small dip along the way.
Where can a Nigerian investor find this figure for a fund?
Most mutual fund fact sheets and investment apps list historical performance, and some include drawdown or worst year figures directly. If it is not shown, you can estimate it yourself by looking at the fund's lowest recorded value after its highest recorded value within the period you care about.
