Dow Falls to End Rocky Week, Yen Rallies

Stocks stumbled in the final session of a tumultuous week Friday as the yen rallied against the dollar and concerns about the U.S. economy still dogged investors after Tuesday's huge drop.

The Dow Jones industrials logged their worst weekly performance in more than four years; until this week, the stock market had gone more than 45 months without a drop of more than 2 percent in a single session.
