Interest rates are near zero and have been for over 4 yrs., creating an overblown bubble of a market that is already trading at OVER 18 times earnings. Remember the late 1990's when emotional greed permeated the market. This is especially true today now that mutual funds have made it common practice to keep as little cash as possible on hand and let inflows and outflows alone mostly control their net portfolio position. Imagine the pop when this baby finally does pop with all that cheap borrowed money being pulled out as fast as they can to pay back the piper before the inevitable finally happens. PM's will be rockin' again once the dust settles and those manager's need to perform in the black and falling stocks won't be the place to go.
