Wall Street ended narrowly mixed Tuesday, as better-than-expected U.S. service sector data partially offset uncertainty about when the U.S. Federal Reserve will start tapering its bond purchases program.
The Dow Jones Industrial Average dropped 20.90 points, or 0.13 percent, to 15,618.22 points. The S&P 500 slid 4.96 points, or 0. 28 percent, to 1,762.97 points. The Nasdaq Composite Index rose 3. 27 points, or 0.08 percent, to 3,939.86 points.
Major stock indices erased early losses after a lower opening, following the release of the non-manufacturing data.
U.S. economic activity in the non-manufacturing sector grew in October for the 46th consecutive month, said the Institute for Supply Management on Tuesday. The non-manufacturing index registered 55.4 in October, higher than September's reading of 54. 4.
Moreover, investors appeared wary of placing any big bets ahead of two major economic data due out later this week. The Commerce Department will release the third-quarter gross domestic product figure on Thursday, followed by October's nonfarm payrolls report by the Labor Department on Friday.
Investors will watch the data closely to seek for clues to the Fed's future plan on its quantitative easing program.
Last week, the U.S. central bank decided to keep easy monetary policy unchanged to bolster economic growth and job creation. Fed officials agreed to wait for more evidence that economic progress will be sustained before making any adjustment.
Boston Fed President Eric Rosengren lauded the Fed's open-ended quantitative easing program in an interview with CNBC on Tuesday, saying the program basically allows the Fed "to do what it takes to get the economy to improve." He also said that he would like to see more improvement in the labor market and economic growth before considering any asset purchases cut.
Investors are also keeping an eye on social media company Twitter, which is expected to price its initial public offering ( IPO) on Wednesday and begin trading on Thursday on the New York Stock Exchange. Twitter's debut is widely anticipated by investors since Facebook's IPO in 2012.
Electric car maker Tesla Motors and mass media company 21st Century Fox reported quarterly earnings after Tuesday's closing bell.

Meanwhile, 21st Century Fox shares fell 2.02 percent in after- hours trading, as the company's first fiscal quarter results missed market estimates.
