How does Australia look from overseas? Wobbly

For the 30 years to December 2014, the S&P/ASX200 index returned 11.4% a year on average, whereas the MSCI World index returned 10.1%.

That might not sound like a huge difference but it means a balance of $10,000 invested here would have grown to $255,009, as opposed to $179,316 if it was invested “over there”.

Australian investors in ASX-listed companies also benefit from franking credits, where company tax paid on profits counts towards the shareholder’s personal tax liability.

For someone in retirement, who pays no tax, $1 of fully-franked dividend is magically transformed to $1.43. Fantastic! Even better, Australian companies pay about twice the yield as international ones.

So we can all give ourselves a pat on the back for having a “home bias” which pays off, but let’s not get complacent.

Out of balance

Probably the most compelling reason to diversify into offshore equities is that the local share market is so heavily weighted towards banks, which are included in the “financials” sector of the listed space, and miners, which show up in the “materials” sector.

Banks make up close to half of the index. When miners are included, about 60% of the market is covered.

Is that a reason to be alarmed? It depends how the rest of the world is divided up. Let’s have a look.

Chart 2 shows the sector breakdown for Australian and international equities holdings for the InvestSMART Balanced portfolio, where offshore holdings are held in a selection of exchange-traded funds over various geographic regions.

Straight away we can see financials is the biggest sector offshore too, but nowhere to the same extent as in Australia. The second biggest sector globally is IT, featuring big names such as Apple, Microsoft, Google, Facebook and so on. Australia’s IT sector is tiny in comparison.

The consumer discretionary, health care, consumer staples and industrials sectors are far more prominent in the offshore markets, and populated by the world’s biggest brand names.

Buy the world

It may feel good to look backwards at the past performance of Australian companies and tell yourself it’s better to focus on what happens at home, but the local share market is way off balance when compared with the rest of the world.

Such a concentration of risk may not be a good thing in times ahead.

If you want to benefit from the business sectors in which Australia is underrepresented, it’s easy to do.
