The stock market is in the midst of a "correction" that has taken the S&P 500 negative over the past year. But the bigger concern among investors is that after years, and really decades of gains, the good times may finally be over, as the market slips into a long period of lower returns.
"From a perspective of five to 10 years, I do think returns are going to be appreciably lower than what their historical average have been, and perhaps lower than people have been counting on," said Albert Brenner, who heads the asset allocation strategy team at People's United Bank Wealth Management. "I think we're looking for equity returns in the U.S. market to be under 6 percent [including dividends] ... a long distance from where they've been historically."
Market performance in the last six years has been rather extraordinary; the S&P 500 has risen an average of 17 percent a year. And in the very long run (going back to 1928) stocks have risen more than 11 percent in the average year, according to data from NYU finance professor Aswath Damodaran.
But some market participants say these sorts of returns are only sustainable for so long. For instance, most of the impressive equity returns have been logged while the U.S. economy has been on the upswing, growing something like 3 percent a year. But with growth stagnant in recent recent years, those sorts of GDP figures are beginning to feel antiquated.
Inflation, too, has been quiescent. Traditionally, market participants have expected equity growth to be generally predicted by real GDP expansion plus the inflation rate; this would have projected that stocks rise less than 5 percent in 2014. Instead they rose more than 13 percent.
