Step aside

In late February, Robert Prechter of Elliott Wave International said "cover your shorts," and predicted a sharp rally that would take the S&P into the 1000 to 1100 range.

With that prediction having come to pass, Prechter is now saying investors should "step aside" from long positions, and speculators should "start looking at the short side."

"The big question is whether the rally is over," Prechter says, suggesting "countertrend moves can be tricky" to predict. But the veteran market watcher is "quite sure the next wave down is going to be larger than what we've already experienced," and take major averages well below their March 2009 lows.
