The facts about long-term investing

Investing is widely considered a long-term game. Short-term losses can prick your emotions — no-one likes to see their portfolio go down in value — but staying in the market and resisting the temptation to tinker can pay off in the end.

“A 94% chance of positive returns?”

Looking at global stock market data between January 1971 and May 20201, if you had randomly picked one day during this period and chosen to invest just for that one day, you would have had a 52.3% chance of making gains — almost a similar odd to the toss of a coin.

Long-term investing dramatically increases your chances of returns. Just weeks more in the market can make a considerable difference.

If you had invested your money for a quarter, or 65 days, during that same 49-year period, your chances of making a profit increased to 65.09%. Investing for any one year would have generated a positive return 71.83% of the time, while investing for ten years increased your chances to 93.91%.

Interestingly, an investor that invested in the stock market for more than 13 and a half years at any point during this period never lost money.

The findings make for pretty interesting reading – compelling even. Just remember, past performance is not a guarantee of future performance.

Time in the market, not timing the market

The longer you invest, the less likely you are to lose money. It’s as simple as that.

Looking at data from developed equity markets between 1971 and 20202, your chances of suffering a loss go down over time. As shown in the chart below, no matter when you invested during this period, long-term investing dramatically increased your probability of avoiding losses.

Clearly, the first year can be stressful, because a year in isolation is more likely to show losses than a longer timeframe. This is when anyone new to investing may feel stressed about the ups and downs in financial markets.

The likelihood of making a loss should go down over time, and so too can those feelings of anxiety – particularly as you grow familiar with the natural ebb and flow of market prices.

What might seem like a big movement one day is but a blip when viewed over several years.

Risk warning

As with all investing, your capital is at risk. The value of your portfolio with Nutmeg can go down as well as up and you may get back less than you invest. Past or future performance indicators are not a reliable indicator of future performance.
