Stocks slipped Friday as investors analyzed mixed signals about the health of the economy and corporate earnings.

The Dow, S&P 500, and Nasdaq all finished slightly lower. For the week, the Dow and S&P 500 ended in the red, while the Nasdaq notched out a gain. The Nasdaq is the best performing major index so far in 2014, up more than 2%.

Stocks had a bumpy start to the year, as emerging markets turmoil and questions about the strength of the U.S. economy weighed on investors. The Dow and S&P 500 are still lower for the year.

But a sense of calm has returned in the past few weeks, and stocks have regained some lost ground. There are also hopes that new Federal Reserve chair Janet Yellen will be able to effectively wind down the central bank's massive bond buying program in an orderly fashion.
