Investment mistake of the month (March 2028): trying to time the market bottom
Key takeaways
- Trying to time the market bottom is a psychological trap caused by loss aversion, hindsight bias and the illusion of control.
- Nobody times market bottoms consistently — not even professionals with billion-dollar research budgets.
- The best trading days follow closely after the worst — investors who stay out of the market typically miss them.
- DCA (investing a fixed amount on a regular schedule) is the antidote: it eliminates emotional decision-making and optimises the average purchase price.
- Automating investments is the key — a standing order from your account prevents emotions from interfering with strategy.
What this mistake looks like in practice
The story is always similar. The market has dropped 15%. You tell yourself: "I'll wait until it falls 25% — then I'll buy." The market falls 25%, but psychologically the situation seems worse — what if it falls to 40%? It reaches 35% and you are still waiting. Then it turns and without you rises 40% over six months. This is not an abstract scenario — it is a description of the behaviour of millions of investors during every significant market decline.
Why the brain sets this trap
The mistake is driven by a combination of psychological mechanisms:
- Loss aversion: a loss hurts approximately twice as much as an equivalent gain feels good. So you want to avoid buying just before another decline.
- Hindsight bias: past market bottoms look obvious in retrospect. It seems you just had to "wait and see".
- Illusion of control: analysing charts and macroeconomic data gives you the feeling that a bottom can be predicted.
What the data says about market timing
No professional investor consistently and reliably calls market bottoms. Hedge funds with billion-dollar research budgets cannot do it consistently. Yet a retail investor with a spreadsheet believes they can figure it out. Studies by J.P. Morgan, Dalbar and other institutions repeatedly document that the average retail investor achieves significantly lower returns than the average fund they invest in — precisely because of poor timing of entries and exits.
How to break the habit: DCA and an emotion-free system
The remedy is simple and dull — and that is precisely why people are reluctant to hear it:
- Dollar-cost averaging (DCA): invest a fixed amount on a regular schedule regardless of price. During a decline you buy more units; during a rise fewer — your average purchase price optimises automatically.
- Automate: a standing order from your account eliminates emotional decision-making.
- Accept uncertainty: you will not identify the bottom in advance. Nobody will. And that is fine.
How to start investing systematically without attempting to time the market is shown in how to build your first portfolio. Why diversification works better than picking the "right moment" is explained in the comparison All World vs. S&P 500. And if dividend stocks as a "safe" way to time the market tempt you, read dividend aristocrats — time in the market beats timing the market there too.
FAQ
Is it truly impossible to time the market?
Occasionally, in a short window, one can get lucky. But doing it consistently and repeatedly is something nobody manages. A strategy dependent on market timing statistically underperforms passive investing over the long run.
What if I buy right before another decline?
That is normal and unavoidable for every long-horizon investor. The important thing is to stay invested and wait for recovery — historically markets have always gone on to surpass previous highs. The key is the horizon.
How will DCA help me during a market downturn?
During a decline you buy more units for the same fixed amount — your average purchase price falls. When the market recovers you earn an above-average return from the units bought cheaply. It works automatically without needing to "know" when to buy.
