The stock market soared in 2013. And some argue that the 28 percent rally in S&P 500 presages good things for the American economy in 2014.
In a recent note, Gluskin Sheff economist David Rosenberg forcefully made the case that history is simply on the side of growth in 2014.
"Going back six decades, what I can assure you is that in the year following a year in which the S&P 500 rose 20 percent or more, real GDP growth was always positive. Never one contraction," Rosenberg wrote. "In fact, the worst year was around 2 percent the subsequent year, which is not so far off the current consensus for 2014. So based on past performance, consider that the worst we can do."
Rosenberg, who until recently was well-known for his bearish stance, goes on to predict even stronger growth than that.
Looking at real GDP growth in years following those in which the S&P rose 20 percent or more, "the maximum was 5.4 percent. The average and median were both 3.8 percent. The mode was closer to 4.5 percent. So expect any surprise in 2014 to be to the upside," remarks Rosenberg (no relation to the writer).
