The week ahead sees the petering out of the flood of company earnings results, and in the coming days, local economic data will be back in the limelight. Major companies to report interim and full-year results will include Lihir Gold and Infigen Energy. On the economic data front there's figures on GDP, retail trade and building approvals. There will be a key speech from Reserve Bank of Australia's assistant governor Guy Debelle, and ASIC chairman Tony D'Aloisio will give a business address. Overseas, the eurozone will have its own GDP reading as well as the ECB decision on interest rates, and then manufacturing and employment data will emerge from the US.
