Description
The S&P/ASX 200 index is a stock market index that tracks the performance of the 200 largest and most liquid companies listed on the Australian Securities Exchange (ASX) by market capitalisation. The index is considered a primary benchmark for the Australian stock market and is used as the basis of multiple index products and ETFs. The index accounts for about 84% of Australia’s equity market as of June 2023. The S&P/ASX 200 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 performance benchmark for managed funds and portfolio returns.
