The value of WA listed stocks rose 18.8 per cent, or $22.5 billion last financial year, despite a decline for the last quarter.
According to the Deloitte WA Index, in June the market capitalisation of WA listed companies decreased by $2.9 billion, finishing the financial year at $140.9 billion.
It was the third successive month of decline for the index.
"The demand for commodities has been subdued in the past month with concerns over China's economic growth, Europe's sovereign debt issues and investors evaluating the possible effects of RSPT in Australia," said managing partner for Deloitte WA, Keith Jones.
The market price of all commodities surveyed declined last month, with zinc down by 7.61 per cent followed by nickel (7.51 per cent), copper (6.18 per cent) and lead (5.37 per cent).
The 'Movers and Shakers' for the month of June include Avoca Resources, Coalspur Mines and Perseus Mining.
The market capitalization of Avoca increased by 33 per cent or by $197.4 million in June to close at $794.8 million. The increase followed the announcement of an upgrade to the ore resource and reserve at the company's Higginsville Gold Project.
Coalspur Mines recorded a $66.8 million (28.2 per cent) increase in market capitalisation to finish the financial year at $303.9 million. This followed the acquisition of new coal leases neighbouring Coalspur's existing Hinton Coal Project.
The market capitalisation of Perseus Mining increased 28.1 per cent or by $210.8 million, and closed at $960.0 million for the month of June. The increase was driven by an announcement of the commencement of site works at the Central Ashanti Gold Project in Ghana.
