Roubini said in 2006 that the worst recession in four decades was on its way. He has attracted attention for his gloomy - and accurate - predictions of the U.S. financial market meltdown.

Roubini said the latest surge is just another bear market rally following the pattern of other rallies after the government intervened. He expects the market will test the previous low because of worse than expected macroeconomic news, disappointing earnings and because banks will fail after the stress tests come out.

"Once people get the reality check than it's going to get ugly again," Roubini said.
