The S&P/ASX 200 Index

To easily grasp the fluctuations of the Australian economy and its stock market, the stocks of 200 companies quoted on the ASX are aggregated in the S&P/ASX 200 Index, or more simply ASX 200, which is widely considered as the benchmark index of Australia.

Calculated from the stocks of the 200 largest corporations by market capitalization listed on the Australian Securities Exchange, the ASX 200 is a capitalization-weighted index, i.e. in which larger companies are weighted more heavily. It represents more than 80% of the total market capitalization on the ASX.

Note that other indices have also been created to evaluate narrower or broader numbers of companies, and consider their economic dynamism through their size in market capitalization: S&P/ASX 20, S&P/ASX 50, S&P/ASX 100, and S&P/ASX 300. The S&P/ASX 200 Index remains however the index that is most often considered by analysts and journalists to follow the Australian stock market activity.
