The fact that the $USD continues in free-fall indicates to me that AG is either losing control or very close to it. Either way, it is very negative for equities because it could bring in foreign selling that has been waiting for this rally to end before pulling out.
If he cannot ram the $USD back up by tomorrow's opening, I will begin taking on some short positions - the rally can continue with the dollar drifting down, but not with it in free-fall.
