For instance, ASX 200 tracks the overall performance of the top 200 Australian-listed companies, weighted by market capitalisation (m-cap). The All Ordinaries tracks the top 500 Australian-listed companies by m-cap.

There are specific subsets of these indices known as sub-indices. Investors can also trade these sub-indices such as ASX 200 resources or ASX 200 materials to gain specific exposure to different parts of the Australian sharemarket.

ASX 200

The ASX 200, maintained by Standard & Poor's, is the most widely cited index that measures the Australian market’s overall performance.

According to ASX, the index is “recognised as the investable benchmark for the Australian equity market, it addresses the needs of investment managers to benchmark against a portfolio characterised by sufficient size and liquidity”. The ASX 200 is comprised of the ASX 100 plus an additional 100 stocks.

A few major constituent stocks of the S&P/ASX 200 index are The A2 Milk Company, BHP, Commonwealth Bank of Australia, ALS, and Altium.

The ASX 200 is capitalisation-weighted. It means that the contribution of stock to the index is relative to its total m-cap. In addition, the benchmark index is also float-adjusted, implying the absolute numerical contribution to the index is relative to the stock's value at the float of the stock.

Dominated by large companies

Launched in April 2000, the index is rebalanced by Standard and Poor’s each quarter to ensure that the constituent stocks meet the eligibility criteria. The index is seen to be dominated mainly by large companies.

The largest ten companies listed on the index accounted for more than 46% of the index as of June 2021.

While four out of 10 stocks belonged to the banking groups, financials accounted for just over a third of the index.

Materials (Resources) was the second-largest group, at 20.6%. In June 2021, the index had a trailing P/E ratio of 65.72 and a dividend yield of 2.8%.
