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 - January 2025
 

The aggregate market capitalisation of Western Australian listed companies soared during January, up 6.1% on the back of strong commodity prices in comparison to December, and a rise in Australian and international equity prices more broadly. The quarterly reporting season for the WA miners saw gold miners enjoying record prices, with gold companies featuring in our top performers for January.

Most global indices were also up, with the exception of the Nikkei, which lost ground on December after the Bank of Japan raised interest rates.
