Wall Street ends down; S&P has worst week since 2012

NEW YORK (Reuters) - U.S. stocks ended lower on Friday as jobs data suggesting the Federal Reserve has room to keep interest rates low for some time was offset by lingering concern over Argentina's default. The Dow Jones industrial average fell 68.97 points, or 0.42 percent, to 16,494.33, the S&P 500 lost 5.29 points, or 0.27 percent, to 1,925.38, and the Nasdaq Composite dropped 17.13 points, or 0.39 percent, to 4,352.64. For the week, the Dow is down 2.8 percent, and the Nasdaq is down 2.2 percent. The S&P is down 2.7 percent, its biggest weekly decline since the week ending June 1, 2012.
