Time in the Market vs Timing the Market: What It Means

You have been putting it off.

Every month, you tell yourself you will start investing properly once you feel more confident. Once you have done more research. Once you are certain the timing is right.

And every month, the markets stay roughly where they are, or dip, or climb a little and you think “ah, I missed my moment.”

Here is the thing nobody tells you: that moment you think you have missed? It does not exist.

Ispeak to people in their forties all the time who are waiting for the “right time” to invest. They watch the news, they check the markets, they read about crashes and crises and think to themselves: “I will wait until things calm down.”

The problem is, things never fully calm down. There is always something. A pandemic. A war. An election. Interest rates. A bank failure. The noise never stops.

And while you are waiting, something quietly happens to your money. It stays still. It sits in an account earning almost nothing. And you miss out on something remarkable.

The same £1,000 invested in the MSCI World in 1980 would be worth around £17,000 today in real terms. That is the cost of doing nothing.

Let me give you some real numbers, because I think they matter more than opinions.

If you had invested £1 in the MSCI World Index back in 1980, it would be worth roughly £108 today. That is not a typo.

The MSCI World has returned an average of 10.7% per year since 1980. That is not a great year every year. It is an average that includes crashes, recessions, and a global pandemic.

Here is what is interesting. Since 1980, global markets have delivered positive returns in approximately 76% of calendar years. Three quarters. If you owned a UK betting shop that won three quarters of all races, you would feel pretty confident.

Notice how the chart above looks like it is shooting upwards at the end. That is not just because markets went up a lot. It is because percentages compound exponentially.

A 10.3% return on £100 is £10.30. But that 10.3% on £10,000 is £1,030. The same percentage, much more money. And after 20 years of compounding, you are earning percentages on percentages on percentages.

On a log scale chart, exponential growth appears as a straight line. Here is the same MSCI World data on a log scale. Notice how it stays roughly linear, which confirms the exponential nature of the growth.

Inflation works the same way. 2.5% inflation on £100 is barely noticeable. But 2.5% on £100,000 erodes £2,500 of purchasing power. Both growth and inflation compound exponentially.

This is why waiting even a few years can have an outsized impact on your final outcome.

Now here is where it gets uncomfortable.

The people who lose the most money are not the ones who stay invested through crashes. They are the ones who try to time things.

But here is the thing. While you are waiting for the right moment, inflation is working against your cash. If your savings earn less than inflation, they are shrinking in real terms, and interest above your Personal Savings Allowance is taxed unless the money sits in a cash ISA. Cash still has a job, though. For money you will spend within three years, cash is the right place to wait, because there is not enough time for shares to recover from a fall. Check what your account pays against the latest CPI figure from the ONS, and move the money if it falls short.

Research from Dalbar, a firm that has studied investor behaviour for decades, found that the average equity fund investor underperformed the very index they were invested in by 2-4% every single year. Over 20 years, that gap is enormous.

Why does this happen? Because when markets fall, people panic and sell. When markets recover and climb, people wait nervously for the next fall. Then they miss the best days and climb back in at higher prices.

And those best days? They cluster right next to the worst days. Research from JP Morgan shows that 75% of the MSCI World's best trading days occur within 10 days of its worst days. You cannot have one without the other.

You are probably thinking: “That all makes sense, but I have already waited so long. Is it too late for me?”

It is not.

Here is something that might surprise you. Even investors who bought right before the 2008 financial crisis, at the absolute peak, were back to their original investment levels within six years. And from there, the market went on to quadruple.

The MSCI World took around six years to recover from 2008. If you had stayed invested, you would have seen your money return to pre-crisis levels and then grow substantially beyond that.

The people who lost badly were those who sold at the bottom in panic and stayed out of the market.

Let me be straight with you. Nobody is promising you riches. The stock market is not a get-rich-quick scheme. It is, however, one of the most reliable ways to grow your money over time if you can leave it alone.

The MSCI World has returned roughly 10.7% per year since 1980, although that includes periods of significant loss and recovery. If you invested £500 a month for 20 years at that average return, you would have roughly £416,000. Of course, past performance does not guarantee future results, but this gives you a realistic frame.

Here is what I would suggest. Do not try to time the market. Do not wait for the perfect moment. Instead, pick a regular amount you can afford to invest monthly, set it up to leave your account automatically, and leave it alone.

Think of it like a direct debit to your future self.

If your employer offers a pension match, make sure you are getting every penny of that first. After that, if you are investing for ten years or more, many people start with a low-cost fund that tracks a broad global index, held inside a stocks and shares ISA or a pension so the growth is not taxed along the way. It is not the only route, and whether it suits you depends on when you need the money and how you would feel watching it drop sharply in a bad year.

You do not need to be brilliant. You do not need perfect timing. You just need to start, and you need to stay.

The data shows that people who do this consistently end up in a better position than people who spend decades waiting for the right moment.

That moment was probably ten years ago. The next best moment is now.
