Just saw a pretty powerful interview with Chanos on Bloomberg. He's been beating the drum about China for awhile, of course, but he says talk of a collapse of the property bubble and a serious economic slowdown is no longer some sort of theory about the future. He says it's happening right NOW. With everyone focused on Europe, people aren't paying attention to the world's growth engine reversing.
I'll add to that the fact that copper has not joined the recent risk rally and (as technicians would say) has crashed through support - now at the lowest level since December.
I'm very tempted to triple my AUD short, but will sleep on it for now.
