By the time the markets closed, the Dow Jones industrial average had fallen 318 points to points to 15,879 -- a 2 percent drop. The S&P 500 dropped 38 points and the Nasdaq Composite dropped 91 points. The Dow fell every day this week, leaving it down more than 3 percent -- its worst weekly performance since mid-May 2012.
