Stocks lost traction Tuesday, a day after climbing above major milestones for the first time.
The Dow Jones industrial average ended slightly lower after rising above 16,000 earlier in the day. The S&P 500, which climbed above 1,800 for the first time Monday, also fell. The Nasdaq slipped, but remains close to 4,000 -- its highest level since September 2000.
With the market trading near all-time highs, there are growing concerns about whether stocks are overvalued.
Jeremy Grantham, who runs money management firm GMO, warned in a letter late Monday that stocks are trading at levels that probably won't support the type of returns investors have become accustomed to.
Grantham said he believes stocks could continue moving higher over the next year or two, but said "investors should be aware that the U.S. market is already badly overpriced." Looking ahead, he predicted "negative returns" over the next seven years.
David Lutz, a managing director at Stifel Nicolaus, said investors pay close attention to Grantham's letters since he has been ahead of the curve in the past.
"Grantham was early in predicting the financial crisis and then reversed course before markets started rebounding in 2009," said Lutz.
Grantham's call came one day after influential investor Carl Icahn said stocks could be headed for "a big drop."
