Wall Street slips as Apple falls, factory activity slows

Apple was down 2.2 percent at $107.83 on a report that chip suppliers were concerned the iPhone maker would cut chip orders for the fourth quarter. The Institute for Supply Management's (ISM) index of national factory activity fell to 50.2 in September, its lowest since May 2013. Mixed signals from the data could complicate the Federal Reserve's plans to raise interest rates this year.
