U.S. stocks ended mixed on Wednesday with the S&P 500 and Nasdaq notching a five-day winning streak,as minutes of the Federal Reserve\'s June policy meeting showed that further improvement in the labor market would be needed before Fed\'s tapering of its bond buying. The Dow Jones Industrial Average lost 8.68 points, or 0.06 percent, to 15,291.66 points. The S&P 500 edged up 0.30 point, or 0.02 percent, to 1,652.62 points. The Nasdaq Composite Index added 16.50 points, or 0.47 percent, to 3,520.76 points. The market opened little changed, but fluctuated afterwards as investors were still not sure about when the Fed would begin to scale back its asset purchases. The Fed minutes released in the afternoon said the U.S. economy continued to improve moderately in the second quarter but many participants indicated that further improvement in the outlook for the labor market would be required before it would be appropriate to slow the pace of asset purchases. In a speech shortly after Wednesday\'s closing bell, Fed Chairman Ben Bernanke said safeguarding financial stability is important for macroeconomic stability and that more needs to be done to strengthen frameworks. On the economic front, wholesale inventories decreased 0.5 percent in May from the prior month, the U.S. Commerce Department said Wednesday, missing market estimates. However, wholesale sales rose 1.6 percent in May. Moreover, U.S. mortgage applications fell 4.0 percent from one week earlier, according to data from the Mortgage Bankers Association\'s Weekly Mortgage Applications Survey for the week ending July 5. China\'s disappointing trade data in June added negative sentiment to the market. Exports in the world\'s second largest economy slipped 3.1 percent in June, while imports fell 0.7 percent. On the previous trading day, U.S. stocks rallied on better-than- expected second-quarter earnings from aluminum producer giant Alcoa, which lifted the Dow and the S&P 500 very close to their record highs in May and the Nasdaq to its highest level since October 2000. According to Thomson Reuters data, earnings of S&P 500 companies are expected to rise 2.9 percent in the second quarter of this year from the year-ago period, while quarterly revenue is forecast to increase 1.5 percent from a year ago.
