This article can help you have conversations with your clients about the value of investing through market volatility.

Key points

  • Helps create a disciplined investment approach
  • Removes the worry of making lump sum investments at the wrong time
  • Enables you to take advantage of market volatility
  • Is not guaranteed to be the best strategy but is a low maintenance and lower stress approach.

What is it?

Pound Cost Averaging is the concept of making regular contributions to your investments in order to smooth out market volatility.

By making regular contributions you naturally purchase fewer units when prices are high and more units when prices are low.

Over the long-term, not only does this create a disciplined investment approach, but this strategy will help take advantage of volatile periods and potentially improve your returns.

Timing the market

One of the greatest things about Pound Cost Averaging is that it removes the worry of making a lump sum investment right before a market decline.

Trying to time the market rarely pays off and often it’s more luck than skill- so even seasoned investors avoid falling into this trap. Using Pound Cost Averaging you can be safe in the knowledge that through volatile periods your money will be working to ensure you purchase units at a lower price with a long-term view.

Rising markets

Of course, there will be exceptions to this philosophy and there is no guarantee that Pound Cost Averaging will result in better outcomes than lump sum investing.

One of these exceptions is a consistently rising market where investing a lump sum from the outset will give you the lowest possible unit price and therefore generate the highest return.

However, the investment journey is rarely a smooth one and given no one knows for sure that markets will consistently rise over your investment journey, the Pound Cost Averaging method can be a useful tool to ensure you don’t buy at the wrong time and are able to take advantage of market volatility.

Examples

Example 1 shows the Pound Cost Average method for two different customers over a volatile period.

Month Unit Price Customer A Contributions Customer B Contributions
January £2.00 £1,000 £12,000
February £1.91 £1,000  
March £1.74 £1,000  
April £1.70 £1,000  
May £1.65 £1,000  
June £1.57 £1,000  
July £1.52 £1,000  
August £1.57 £1,000  
September £1.61 £1,000  
October £1.65 £1,000  
November £1.74 £1,000  
December £1.83 £1,000  

 

Total Unit Purchased 7,077 6,000
Average Price Paid £1.71 £2.00
Final Value £12,923 £10,956

Customer A invests £1,000 a month over the year whereas Customer B invests £12,000 in January. Across the year, the market falls and rises with the unit price following the same trend.

By December, Customer A has been able to take advantage of falling prices and has purchased over 1,000 more units and paid a lower average price than Customer B. This leaves Customer A with almost £2,000 more over the 1-year time frame.

The purple line shows investment in the ABI Mixed Investment 20-60% shares with a single payment of £24,000 whereas the orange shows regular £1,000 contributions over the same period.

Example A

Example A, shows a real example of how using Pound Cost Averaging through the last financial crisis in 2007 to 2009 may have been beneficial.

You can see that the Pound Cost Averaging method here has resulted in a greater number of total units purchased, a lower average price paid and a higher final value.

Example B

Example B then shows a real example (using the same basis as in Example 2A) of how the Pound Cost Averaging method may result in poorer outcomes in a market which overall, has net positive returns.

What it really comes down to however, is individual investor preference. Using either method (or even a mixture of both) a well-structured, long-term investment strategy should help you on the way to building enough investments to support you through retirement.
