How pound cost averaging helps you through market swings


As you already know, the market can go down as well as up. And while it’s tempting to take action in a downturn, one of the best ways to ride the waves of the market is to have a plan and stick to it. Know your long-term goals, invest regular amounts each week and benefit from pound cost averaging.  


What is pound cost averaging? 

Pound cost averaging refers to investing small amounts of money regularly. It can teach you a non-emotional approach to investing because you’ll be investing no matter what state the market is in. 

You’ll capture the average return of the market because you’ll be buying regularly – when prices are high, low and everything in between. This means that over time, you could end up with a larger investment position than if you only bought into the market once or twice a year.

Time in the market vs timing the market 

While in theory, it’s possible to time the market – to sell just before prices go down and buy back just before they rise – in practice, it’s almost impossible to do, and you’ll lose lots of sleep trying! Plus, selling up and being out of the market can be extremely costly. Even though your instincts would tell you otherwise, getting out of the market can be the costliest mistake of all. As we mentioned earlier in this series, a JP Morgan study from 2022 found that, over a 20-year period, seven of the 10 best days in the market (based on the S&P 500 index) occurred within 15 of the worst days.



We saw examples of this in 2020. Covid-19 rocked the markets and caused widespread declines, which led to never-before-seen stimulus measures from governments around the world. Yet, the S&P 500 increased by 9.4% on March 24 from the day prior, its biggest one-day gain since 2008. The Dow Jones Industrial Average also soared 11.4% on the same day, making this its strongest day since the Great Depression in 1933.**

So, even though the initial dips were scary and might’ve led some investors to sell up and get out, those investors who held onto their positions and spent more time in the market would have likely benefited from the market rebounds. 


Pound cost averaging vs lump-sum investing 

Pound cost averaging is often compared with lump-sum investing. With pound cost averaging, you’ll make regular contributions, which don’t have to be large. With lump-sum investing, you’ll invest a larger amount, but you won’t do it as often. 

If you opt for lump-sum investing, you might miss out on the market average and your money might not be able to buy as much if the market is high when you make your investments.

You can look for a middle ground between pound cost averaging and lump-sum investing. For example, if you opened a Stocks & Shares ISA, you might make an initial lump-sum investment and then keep up with regular weekly or monthly contributions. Since all investing should be considered as long term, you could even make more lump-sum payments over the years alongside your regular contributions.

At Moneybox, we offer both lump-sum investments and regular contributions. You can set up a weekly deposit, a monthly payday boost, make one-off deposits or choose to round up the spare change from your everyday purchases – tailoring your contributions to whatever works best for you.

So, what next? As an investor, it’s important to be prepared for the ups and downs of the stock market. If you invest weekly, like hundreds of thousands of Moneybox users, the smartest decision you can make is to leave your money invested, know your long-term goals and continue to benefit from pound cost averaging.

*Annual returns are net of fees and based on the scenario of £1,000 invested in 2013 followed by monthly deposits of £50. Where available, returns data for the selected funds have been used. Where the fund has a shortened performance history, we have used the appropriate index to simulate performance. This is the case for the Global Shares fund prior to March 2014 and the Global Property Shares ESG fund prior to October 2014. Please note, historic performance is not a reliable indicator of future performance.

All investing should be regarded as long term (minimum five years) and historic performance isn’t a guarantee of future returns. The value of your investments can go up and down, and you may get back less than you invest. We don’t provide investing advice, and investors should make their own investment decisions or contact an independent adviser.
