Market timing is the act of moving money in and out of the financial markets or switching between fund asset classes, while trying to predict the future direction of the market. In other words, it involves making a series of decisions based on an endless cycle of fickle market and economic conditions.

Before giving in to the lure of market timing, here are some of the important factors to consider:

• Even if you sell your shares at the market’s peak, your good fortune is quickly on the line again when you try to guess the exact right time to re-enter the market. It requires two miracles to execute the perfect market timing trade – and then a third miracle if it can be repeated. Only Tom Cruise in Top Gun: Maverick has achieved three miracles[i].
• Market timing is a tedious, time-consuming and imperfect pursuit that has no guarantee of success in the long run. Warren Buffett has said “market timing is both impossible and stupid”[ii].
• When you time the market, you’re betting against experienced market analysts who are also trying to make timely buying and selling decisions in an attempt to beat market averages. Yet even with all their experience and resources, those analysts and fund managers tend not to do much better than an index in the long run[iii].

Of course, the financial media is designed to pander to emotional biases – otherwise no-one would read or watch any of the predictions they report on. It’s understandable that volatility in the market often tests the resolve of investors, and the more volatile the market the more likely investors will experience emotions like fear and even panic when it comes to their investments. But keep this in mind:

• Volatility is normal in an active market.
• If you’re a long-term investor, dozens of studies have shown that selling your stocks or funds during a volatile period may have a negative impact on your long-term returns.
• While it’s easy to get out of the market when things seem to be heading south, it’s also very easy to miss the best performing days by not getting back in at just the right time. And if you miss those good days, your performance will likely be much worse than if you had simply stayed in the market the whole time.

The impact of being out of the market for a short time can be profound, as shown by a hypothetical investment in the stocks that make up the S&P/ASX 300 Index .

In the example below[iv], a hypothetical $1,000 investment made in 2000 turns into $4,932 for the 22-year period ending 30 June 2022. Over that 22-year period, miss the S&P/ASX 300’s best week, which ended 30 March 2020, and the value shrinks to $4,328. Miss the best three months, which ended 23 June 2020, and the total return falls to $3,742.
