SMH - The weaker-than-expected building approvals data has tarnished some of the Aussie's shine today; it has caused the Aussie to ease back towards the $US0.9400 handle. The Aussie's direction in the short term will be volatile - with important domestic and US data due before the end of the week. US ISM manufacturing later today and payrolls on Friday are among the big hitters. Australian retail sales is due tomorrow. It means that action is likely to be choppy.
