- Market timing is less effective than long-term investment strategies.
- 90% of active investment managers do not outperform market indices.
- Missing crucial market days can significantly impact investment returns.
Understanding the Ineffectiveness of Market Timing
Market timing's appeal is understandable but misleading. Like predicting the British weather for an outing, it's fraught with uncertainty. Just when conditions seem favourable, the market can shift, derailing anticipated gains. This unpredictability often results in outcomes that fall short of expectations.The Impact of Missing Key Market Days

Consider the scenario where a £100,000 investment misses the market's best days. Over a thousand 20-year rolling periods from January 1915 to December 2022, the absence from the market during its peak days has profound effects on potential growth. Here's a breakdown:- Fully Invested Return: Staying fully invested could grow your investment to £887,586, showcasing an annualised return of 11.53%.
- Missing the 5 Best Days: If absent for just these days, your end total would decrease to £623,039, with annual returns dropping to 9.58%.
- Missing the 10 Best Days: The total further reduces to £482,235, with an 8.18% return.
- Missing the 20 Best Days: This scenario yields £321,125, a 6.01% return.
- Missing the 30 Best Days: The most drastic drop, to £234,155, results in a mere 4.35% annual return.
Market Timing Versus Market Resilience
Skeptics of active management might question the likelihood of missing all the best days. Yet, data reveal that investors frequently overlook these golden opportunities during attempts to time the market. Notably, the best days often follow closely behind the worst, particularly during volatile periods, underscoring the challenge of precise market timing. Real-world examples, such as significant market rallies following the onset of the COVID-19 pandemic and during the 2008 financial crisis, illustrate the unpredictability and potential for swift recovery, emphasising the value of steadfast investment strategies.Sources: Hartford Funds, Ned Davis Research, Morningstar.
