The US dollar index dropped from around 84 to around 79 in anticipation of QE-infinity. It is a classic buy the rumor, sell the news kind of thing.
If I had to guess, I'd say we have a ways to the ultimate low for the US dollar this go round. Of course I have no future reading capability, but have noticed that there is a gap in UUP between around 21.40 and 21.20 that never got filled on the way down and then on the way up several months ago. I think that will be filled and then it will be time to watch the buck closely for signs of it making higher lows, which would signal strengthening and could be a prelude for the next recession (in this depression).
Jshaefr1, here's my thoughts. If the housing market keeps going up, jobs will increase, dollar will continue to strengthen, then feds will raise rates.Once they raise interest rates, the dollar will weaken. Does this make sense to you?
