According to USA Today's most recent economic outlook survey, "Economists See Growth Slowing, Recession Risk Falling," the majority of experts are cautiously optimistic:

And yet, as John Hussman notes in this week's Hussman Funds' Weekly Market Comment, "Warning: Goat Rodeo," the hard data paints a much less sanguine picture of the risks ahead.
While we typically discourage drawing inferences from any single indicator, it's at least worth noting that with the release of Q4 GDP figures, the year-over-year growth rate of real U.S. GDP remains below 1.6% (denoted by the red line below). A decline in GDP growth to this level has always been associated with recession, usually coincident with that decline, though with a two-quarter lag in two instances (1956 and 2007), and with one post-recession dip in growth during the first quarter of 2003. As it happens, the GDP growth rate dropped below 1.6% in the third quarter of 2011.

Given the strong and rather obvious relationship between the most recent year-over-year rate of GDP growth and the prospect of oncoming recession, it's difficult to understand why Wall Street so completely rejects the likelihood of an economic downturn.
Because this time it's different?
