Why do so many talk about the usd falling?......have they not noticed the market action of the past 4 months? - and looks to me like another leg to go.

I have heard the arguments for a weak usd but atm it is not working that way.

Generally when a price is rising and all the talk is about an impending fall - the market will continue to rise until the doubters give up.
