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.

This year, the market capitalisation of Western Australian entities listed in the WA Index closed at A$494.3 billion, a huge 36% increase from 2025. By comparison, the ASX All Ordinaries increased by 2.4%. A truly remarkable result.
Several factors contributed to this growth. Global macroeconomic conditions pushed gold to record highs, accounting for a significant share of the overall increase. Once the conflict in the Middle East started towards the end of the March quarter, gold began to pull back, but energy stocks in both oil and gas and battery minerals picked up the pace and recorded significant gains. The sector also attracted new money, with significant capital raisings by existing companies and a spate of reasonably sized IPOs also making their mark.
