What are the largest companies in Australia by market capitalisation?

Gazing upon a list of Australia’s 10 largest publicly listed companies by market capitalisation provides a succinct insight into the structure of the Australian economy. The major mining companies, who’ve for years benefitted the Chinese economic boom, and the Big-4 banks, who’ve enjoyed many of the spoils of several property booms, occupy 6 out of the 10 spots on the list, and 4 out of the top 5.

More broadly, Financial Services companies make up 28.1% of the ASX200, while Basic Materials make up 20.1%. Healthcare is the next highest concentration, making up 9.9% of the benchmark.

It’s certainly a dense concentration of value. And while it’s true that the overall fortunes of the Australian economy and ASX are leveraged significantly to the fate of the miners and banks, for investors and traders interested in entering the Australian share market, it is far from the full story. Conveying the changing face of the Australian economy, global investment bank Macquarie Group holds its weight amongst its financial services cousins, biotechnology firm CSL is a growth-investor favourite, and retail giants Woolworths and Wesfarmers are perennial investor staples. Other stocks, such as Afterpay, while not in the top ten, are catching up fast. Afterpay is currently the 14th largest publicly listed company in Australia – an impressive feat given that it was founded just seven years ago.

How to trade the largest companies in Australia

Trading Australia’s large cap shares can provide a trader with the ability to benefit from changes in the share price of some of nation’s biggest corporate names. Moreover, share CFDs allows a trader to gain exposure to movements in Australia’s largest companies, while not owning the underlying stock. Companies with large market capitalisation are generally much more liquid than smaller, more volatile stocks, meaning relatively lower risks for traders wishing to trade in the equity market.

Developing a trading strategy is very important before jumping in to trading shares or share CFDs. One part of this process is gaining an appreciation of what makes the price of a stock move. Some traders prefer to trade 'top down' by looking at broader macroeconomic themes and applying them to certain industries, and then particular stocks within that industry. Others take a 'bottom up' approach by analysing a company’s fundamentals, to determine whether the current market price properly reflects future earnings.

Trading Australia’s top 10 companies by market capitalisation affords amply opportunity to benefit from changes in the Australian corporate and economic environment. Whatever the approach taken, trading shares is generally considered to be riskier than when trading a currency, index, or major commodity market. Of course, this means the potential for higher returns, but an adequate risk management strategy ought to be implemented by a trader to protect their capital.
