If you've looked at your investment statement recently and felt your stomach drop, you're not alone, and you're not wrong to feel it. The JSE delivered a stellar 37% in 2025, then spent the first half of 2026 giving a good chunk of it back. Watching numbers you'd celebrated a few months earlier slide in the other direction is genuinely unpleasant.
So let me tell you the single most valuable thing I can, and I'll say it plainly: when markets drop, the right move is almost always to do nothing.
That sounds too simple to be advice. It isn't. Doing nothing, deliberately, calmly, on purpose, is one of the hardest and most valuable skills an investor can develop. Because the biggest threat to your long-term returns isn't the market falling. It's what you're tempted to do when it does.
The market isn't the risk. Your reaction is.
Falling markets are not a malfunction. They are a completely normal, built-in feature of investing. Over any long investment horizon, you will live through multiple corrections (drops of 10% or more) and probably a few proper crashes. This is not a sign something has gone wrong. It's the entry price for the long-term returns that shares provide.
Here's the part people underestimate: your brain is actively working against you during a downturn. Two hard-wired instincts do the damage.
Loss aversion. Decades of behavioural research show that the pain of losing money is felt roughly twice as intensely as the pleasure of gaining the same amount. A 15% drop doesn't feel like a 15% drop. It feels like an emergency. That emotional intensity is what pushes people to sell at exactly the wrong moment, just to make the discomfort stop.
Recency bias. When markets are falling, your mind quietly assumes they'll keep falling forever. When they're rising, you assume the good times are permanent. Both feelings are equally wrong, and both lead to buying high and selling low, the exact opposite of what builds wealth.
The brutal cost of panic-selling
When you sell during a drop, you do two damaging things at once. You lock in a loss that was, until that moment, only on paper. And you take yourself out of the market, which means you have to be right a second time about when to get back in. Almost nobody is.
This matters more than most people realise, because market recoveries are violent and unpredictable. The best days in the market cluster remarkably close to the worst ones, often within days or weeks. Study after study across global markets has found the same thing: an investor who stays fully invested dramatically outperforms one who misses even a handful of the market's best days. Miss the ten best days over a couple of decades and you can cut your final return roughly in half.
And when do those best days tend to happen? In the middle of the scariest, most volatile periods, precisely when the panic-seller has already fled to cash. You cannot capture the recovery if you weren't in the market when it arrived, and it never sends a save-the-date.
History's most reassuring pattern
Zoom out far enough and every market chart tells the same story: a jagged line that goes up and to the right, interrupted by drops that felt like the end of the world at the time and look like small dips in hindsight.
The 2008 financial crisis. The 2020 COVID crash, when markets fell roughly a third in a matter of weeks. Every emerging-market wobble in between. In the moment, each one felt existential. Every single one recovered, and went on to new highs. The JSE has, over the long run, delivered returns comfortably ahead of inflation for investors who simply stayed the course through the noise.
That's not a promise that any single drop will recover on your preferred timeline. It might take months, occasionally years. But it is a powerful, repeatable historical pattern: markets that fall have, eventually, always recovered for the patient, diversified investor. The people who got hurt permanently were almost always the ones who sold at the bottom and never got back in.
So what should you actually do?
"Do nothing" doesn't mean bury your head in the sand. It means act on your plan, not your adrenaline. Here's what that looks like in practice.
Keep contributing. If you invest monthly, a market drop is quietly working in your favour, your same rand buys more units at lower prices. This is rand-cost averaging doing its job. The worst thing you can do is pause your contributions during a dip; you'd be switching off the discount exactly when it appears.
Zoom out. Stop looking at your portfolio daily. If your goal is 15 or 20 years away, a bad six months is statistical noise. Checking less often isn't lazy. It's one of the most effective risk-management tools you have, because you can't panic-sell a number you haven't looked at.
Revisit your plan, not your positions. A downturn is a good moment to ask "has anything about my life or my goals actually changed?", not "what's the market going to do next?" If the answer to the first is no, your plan almost certainly still holds.
Rebalance, if anything. Disciplined investors sometimes use downturns to rebalance, trimming what's held up and topping up what's fallen, bringing the portfolio back to its target mix. Done systematically, this is the rare form of "buying low" that removes emotion from the decision. It's the opposite of panic-selling.
When you genuinely should act
To be clear, "do nothing" is the default, not an absolute rule. There are legitimate reasons to make changes, and they have nothing to do with fear:
Your personal circumstances have changed. You're closer to needing the money, your risk tolerance has genuinely shifted, or your goals are different. Your portfolio has drifted well away from its intended allocation and needs rebalancing. Or there's a real tax or estate-planning reason to restructure. These are plan-driven decisions made with a clear head, the exact opposite of selling because a headline frightened you.
The uncomfortable truth
Most people don't fail at investing because they picked the wrong fund. They fail because they couldn't sit still. They did everything right for years, then let a few frightening months undo it, selling at the bottom, waiting for "certainty" that never comes, and climbing back in only once prices had already recovered.
The investors who build real wealth aren't smarter or luckier. They're calmer. They understood in advance that drops were coming, decided ahead of time how they'd respond, and then had the discipline to actually do it when the moment arrived.
That's the whole game. Not predicting the next drop, nobody can, but deciding, while you're calm, exactly how you'll behave when it comes.
If the current volatility has you second-guessing your plan, that's the perfect reason to talk it through with someone before you act on the feeling.

It's stopping you from making the one big mistake that would have cost you everything.
