On the US/Macro setting and its effect on Australian markets Alex Leyland from Leyland Private Asset Management says, Don't forget that the US are the engine room of the global economy and they have always found ways to re-invent themselves. The US is 25% of GDP, if they start doing well that'll impact on global confidence and suck a lot more exports out of China. As long as you have growth in the big economies then that is just going to pull us (Australia) along with it. It's amateur psychology but if people are feeling more confident then things will improve.
