NEW YORK, Sept 8 (Reuters) - The Dow and S&P 500 are down in late afternoon trading on Monday, led by declines in energy shares and Apple, while the Nasdaq is up a tad.
Apple shares are down 0.7 percent.
Energy shares are the weakest sector on the day, with the S&P energy index off 1.7 percent. Shares of Exxon Mobil are down 1.5 percent and Schlumberger's are down 2.2 percent, among the biggest drags on the S&P 500.
Brent crude traded below $100 a barrel for the first time in more than a year as Chinese and U.S. data pointed to slower-than-expected growth in the world's top oil consumers, while U.S. crude settled lower.
Research from the San Francisco Federal Reserve indicated investors expect rates to stay low for longer than the central bank itself does. Recent market momentum has been driven by accommodative Fed policy, including bond purchases and low interest rates.
The Dow Jones industrial average is falling 38.68 points, or 0.23 percent, to 17,098.68, the S&P 500 is losing 8.63 points, or 0.43 percent, to 1,999.08 and the Nasdaq Composite is dropping 0.92 points, or 0.02 percent, to 4,581.98.
