Questions abound regarding the current direction of the equity market. In one camp are those who view the current European troubles and general market pullback as a temporary setback amid an ongoing economic expansion and bull market; they're buying the dips. The other camp is worried that we're due for a double-dip recession or worse, and that now is the time to bail out of equity positions and move to cash, regardless of how "safe" one considers one's holdings.

Outside of these two perspectives are the stocks that have rocketed higher since the year began and don't seem to pay any respect to what the broad market is doing. A few stocks on the Russell 3000 universe of stocks had at least doubled in price since the year began. That compares well against the iShares Russell 3000 Index ETF (NYSE:IWV), which is flat on the year. For those out there who fancy themselves stock pickers, did you find any of those double baggers?
