NEW YORK, Sept. 3 (Xinhua) -- Wall Street traded mixed Wednesday as investors worried about the U.S. economy outlook.

    The Commerce Department said orders for manufactured products rose by 1.3 percent in July. The figure was higher than the 0.8 percent predicted by economists.

    However, the Federal Reserve said in its latest report that the United States is experiencing slow economic growth. The U.S. unemployment rate jumped in July to a four-year high of 5.7 percent while manufacturing activity was "weak or declining" in most Fed regions.

    The Dow Jones industrial average rose 15.96, or 0.14 percent, to 11,532.88. The Standard & Poor's 500 index fell 2.60, or 0.20 percent, to 1,274.98, and the Nasdaq composite index fell 15.51, or 0.66 percent, to 2,333.73.
