The ASX 200 will likely open marginally lower in spite of positive leads from overnight trading. Both Europe and Wall Street were higher on signs that the China-US trade negotiations are approaching a positive conclusion. Bond yields, commodities and the Aussie dollar were all higher. It is all quiet on the domestic economic front. In local company news, Harvey Norman trades ex-dividend. Despite the likely negative start, lingering demand for stocks should see the ASX 200 close marginally higher.
