The monthly Deloitte Western Australia Stock Exchange Index is compiled from publicly available information provided by the ASX and Capital IQ on the market capitalisation of each Western Australian listed company.

A company is included as a Western Australian Company where its ASX Home Exchange is in Western Australia, regardless of whether the company is dually listed.

The base period of the Deloitte WA Index is May 2000 and for the purposes of the index this month is given a notional value of one.

Please note, if a company has been suspended or delisted during a particular period no data will be included for that month and all subsequent months until the company is re-listed or the suspension lifted. Historical information regarding the company's market capitalisation will continue to be included in the calculation of the index.

The latest edition - WA Index - May 2024
 

The aggregate market capitalisation of Western Australian listed companies increased by 0.8% during the month of April to close at $384.6 billion. Commodities such as base metals were a large driver for the positive performance. 

The tracked indices showed mixed signals comparative to the WA market, led by a 2.4% increase by the FTSE 100 while the S&P 500 registered a decline of 2.5%. The FTSE 100 performed strongly in April 2024, following UK inflation declining to below that of the US, fueling expectations a rate cut could arrive in the UK well before the US.
