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 - April 2025

April saw US President Donald Trump outline his liberation day tariffs on the rest of the world, resulting in significant equity and commodity volatility. Tensions later eased toward the end of the month, with China and the US agreeing to trade talks, restoring some confidence.

At close, the S&P 500 and FTSE closed marginally lower, with the Nikkei and All Ords up on March figures. Meanwhile with commodities, Gold remained strong with investors seeking safe haven from volatility, while Zinc, LNG, and Crude all fell on reduced demand.
