What is diversification and why is it important in your KiwiSaver fund?

  • Fabook Messenger Sharing Link

Let’s say your KiwiSaver fund consists of only stocks within the mining industry. If the government announced that coal mining would be banned and that energy sources would now come from renewable energy, share prices of mining stocks will collapse.

Since you only have one type of industry in your investment portfolio, it will experience a great loss in value.

On the other hand, if your portfolio also consists of renewable energy stocks, then the positive performance of your renewable energy stocks will offset the negative performance of your mining stocks. This is diversification.

Explaining diversification in more detail 

Diversification is achieved by mixing a wide variation of assets within an investment portfolio. This variation should include different types of assets, industries, and countries as they would behave in different ways at different times.

You are exposed to different types of risk when you invest, including market risk, volatility risk, and diversifiable risk. Some of these risks can be minimised significantly by diversifying your investments. 

Diversifiable risk like the example above is unique to a specific company, industry, market, or country and can be considerably reduced through diversification.This investment strategy is essentially very similar to the old saying “don’t put all your eggs in one basket”.

How KiwiSaver funds diversify their portfolios

Like many other types of managed funds, KiwiSaver funds make it easier to manage risk by spreading your money across a range of different assets. For example, let’s take a look at the Milford Active Growth Fund.

Spark New Zealand


Fisher & Paykel Healthcare


Summerset Group Holdings

Lowe’s Companies Inc


Top equity holdings as of 31 August 2020 from Monthly Fact Sheet.

We can see that their top ten equity holdings consist of shares from many different industries from technology to retail in New Zealand, Australia, and the United States. By also investing in international shares in their portfolio, this KiwiSaver fund is able to minimise and offset the risks that come with only investing in shares from one country. Volatility in NZ might not affect the values of shares in the US, so investing in different parts of the world is important to further diversify your portfolio.
