The nine-year-old bull stock market may be running out of wind, according to some investment gurus.
"It's been almost too good," said Jim Paulsen, chief investment strategist at the Leuthold Group, who was one of the early believers in the 2009 market rally from the depths of the Great Recession.
"And when things have been too good in the market, it can take just one bad item …," Paulsen said. "I don't see a bear market because we're nowhere near a recession. But most of the good things are already priced into the market."
The Standard & Poor's 500 stock index is up about 20 percent this year. Moreover, the total return of the S&P 500, including reinvested dividends, is 18 percent compounded annually since March 2009.
The S&P 500 index peaked in 2007 at about 1,550, several months ahead of the market collapse and 2008-09 recession.
It crossed 1,550 and into record territory again in 2013, as the economy, employment and confidence returned to the United States after the job-and-wealth scorching recession. The market soared above 2,600 in November, amid continued low unemployment, record corporate profits, recent-quarter economic growth and low inflation and interest rates.
The stock market has been a good place to make money for eight years.
Investors who shunned the market when it was ailing-to-climbing early in the halting economic recovery have come back in droves. Many now-exuberant investors believe that 3 percent economic growth will improve earnings and stock prices.
