what are you predicting it to head back down to if that was the bubble part? 5 years on and we are still basically at the top of what you are calling the bubble, is it headed back to what i guess you would be calling 'pre-bubble' on that chart of say $350-400/oz?
and if we chart AUD gold it isn't even worth talking about as it's been sitting up there for such an extended period
is there a classical economic definition of how it has to fall off a cliff or how steep the rise has to be in order to get in 'bubble' class? (genuine question)
