Explore latest and special editions of the Deloitte WA Index

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.
