In 1976 John Vogel, founder of Vanguard Investments, began offering the first US-based Stock Index Fund. This marked the first time that investors and their advisers could easily purchase large collections of individual stocks at relatively low cost. This simple innovation would, in time, go on to change both the way people invest and the financial industry at large. Today, it is estimated that over $10 trillion of assets are invested in index funds (1).

While index funds have greatly simplified the process of buying many stocks at once, they are not necessarily an ideal 1-stop-shop for investors. This is because, as attractive as the idea of buying one product and forgetting about your investments until you need them may seem, doing so will likely leave you dangerously under-diversified. As with many things, the devil in index investing is in the details.

Australian Index Exposures

Take for example the most popular Australian stock index the S&P/ASX 200, this index is created using what’s called a market cap weighted index. This means that a stocks proportion of the index is determined by the market value of the company.

Therefore, the larger the company, the greater the greater share of the index it represents at any given time. The current top 5 holdings of the ASX/200 are (2):

1. BHP Group
2. Commonwealth Bank Australia
3. CSL Ltd
4. National Australia Bank Ltd
5. Westpac Banking Corp

A result of this index construction methodology is that profitable industries with many large public companies end up representing an oversized proportion of the index. For instance, the breakdown of the top 5 sectors in the S&P/ASX 200 is as follows (3):

• Financials 28.8%
• Materials 25.8%
• Healthcare 9.1%
• Consumer Discretionary 6.9%
• Real Estate 6.7%

As you can see, the Financials and Materials sectors dominate the index and make up over 50% of index’s total. Compare this with the US S&P 500, where Financials and Materials represent only 13.7% of the total index, and it becomes clear that the Australian share market, as represented by the ASX/S&P 200, may not present an ideally diversified investment exposure.
