What is the ASX200?

The abbreviation “ASX” stands for Australian Securities Exchange, which is the primary exchange for Australian stocks based in Sydney. The “ASX200” is a benchmark index that was created in the year 2000 and consists of the 200 largest public companies by market capitalisation listed on the ASX. As with all indices, the ASX200 is measured in points and tracks the combined movements of all 200 stocks within the index. Daily changes to the index are measured in points or percentages. The ASX200 performs quarterly rebalances, where the index adds and removes firms that have qualified or no longer qualify as ASX200 companies using the previous six months data.

How does a company qualify for the ASX200?

To be included in the ASX200 a stock must satisfy three conditions:

  • The stock must be listed on the Australian Securities Exchange as an ordinary or preferred stock.
  • The stock must satisfy liquidity requirements. Liquidity basically means how often the stock is traded and at what volume, indicating how easily an investor can buy or sell the stock. For the ASX200, the stock must have a certain level of liquidity, however the liquidity cannot be dominated by a small group of investors.
  • The stock’s float-adjusted market capitalisation must also satisfy the requirements of the index. In the ASX200 that generally means that the company’s float adjusted market capitalisation must be amongst the 200 biggest on the ASX. The market capitalisation cannot include large strategic holdings or issuing of new shares.

Note that these three conditions are required for inclusion into the ASX200, however if an existing ASX200 company falls outside of the conditions temporarily, it does not mean that it is immediately excluded from the index. The index is rebalanced quarterly.
