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 - June 2024
 

The aggregate market capitalisation of Western Australian listed companies decreased by 2.2% during the month of May to close at $376.0 billion on the back of volatility across commodity markets and the de-listing of Azure Minerals, AVZ Minerals and Orecorp. 

The tracked indices performed well in comparison, with the S&P 500 and Nikkei increasing by 3.6% and 3.9% respectively; with the US Market buoyed by strength in the technology sector. However, the FTSE decreased by 2.3%, with investors' fears over potential interest rate increases because of higher-than-expected inflation. Domestically, the All Ordinaries performed well in line with global markets, following the S&P and Nikkei by rising 3.2%.
