Markets were mostly down on Thursday.
The S&P 500 fell 0.4 percent, as did the Dow Jones Industrial Average, ending its nine-day rally.
Elsewhere, the STOXX Europe 600 fell less than 0.1 percent while the Nikkei 225 rose 0.8 percent.
Investors are unperturbed by the decline on Thursday.
"We've got a long way to run but this is a breather that we need, quite frankly," said Ben Willlis of Princeton Securities Group.
Maybe investors are becoming overconfident. Bloomberg sees signs of exuberance in stocks.
The S&P 500 and Dow Jones Industrial Average both closed at record highs on Wednesday and a peek at the underbelly of market flows and sentiment suggests that a sense of euphoria has enveloped investors.
