Wall Street suffered its fifth straight week of stock market losses after an unexpected uptick in the jobless rate became the latest sign of a sputtering economic recovery. The Dow Jones Industrial Average sank 97 points Friday, or 0.79%, to close at 1,300. MSNBC.com reported the Dow hasn't suffered such a long losing streak since July 2004, though the index it is still up 5.2 percent for the year. After the Labor Department announced the unemployment rate rose to 9.1% last month, Pacific Investment Management Co. CEO Mohamed El-Erian told Bloomberg News the "worrisome" report "should jolt policy makers into realizing the U.S. faces an employment crisis.”
