Cboe Australia 200 Index

The Cboe Australia 200 Index (also known as the CXA 200 Index) is a free-float capitalisation weighted index that captures approximately 80% (by total market capitalisation) of the Australian equity market. The index measures the performance of the largest 200 companies, whilst considering several criteria including free float and liquidity. Two important features of the CXA 200 Index are that:

1. All index values, whether real-time or end-of-day, are calculated using transacted prices from the Cboe Australia market;
2. Only primary listings of the top 250 Australian stocks are eligible for inclusion in the index, hence CHESS Depositary Interests (CDIs) and foreign domiciled stocks are not eligible.
