S&P/ASX 20

The S&P/ASX 20 index is a stock market index of stocks listed on the Australian Securities Exchange from Standard & Poor's. While the "ASX 20" often simply refers to the 20 largest companies by market capitalisation, the S&P/ASX 20 Index is calculated by using the S&P Dow Jones Indices market capitalization weighted and float-adjusted methodologies. All 20 companies also feature in the S&P/ASX 50.
