Description

The ASX 20 index is a stock market index that tracks the performance of the 20 largest and most liquid companies listed on the Australian Securities Exchange (ASX) by market capitalisation. The index is considered a representative sample of Australia’s blue-chip securities. It accounts for about 47% of Australia’s equity market as of June 2023. The ASX 20 index is calculated and maintained by S&P Dow Jones Indices, a leading provider of global index services. The index is float-adjusted, meaning that only the shares that are available for public trading are included in the calculation. The index is rebalanced quarterly, in March, June, September, and December, to reflect changes in the market composition and liquidity. The index is widely used as a reference point for Australian equity funds and ETFs.
