If you got out in July of 2008 you were lucky. Otherwise you are digging yourself out of a nearly bottomless pit. So when the WSJ starts with the "poised for big move in 2011" stuff or glowing headlines like Dow up 11% for the year... try and keep things in some sort of balance.
A sense of history is sometimes a good thing but with the vast majority of recommendations coming out of Wall Street centering on buy buy buy rather than sell sell sell....well....ya know.
