Dow futures join global selloff as Apple, data weigh
U.S. GDP data due at 8:30 a.m. Eastern time

That leaves investors to look ahead to the first estimate of U.S. growth in the third quarter later Friday for a reading on the economy’s recent strength. http://www.marketwatch.com/story/stock-future...beforebell
