Wall Street finished a difficult week lower Friday as investors, restrained by uncertainty about the economic impact of Hurricane Katrina, had little reaction to a sharp decline in oil prices and less unemployment. Despite the week’s fluctuations, the major indexes ended with moderate gains.
At the close of trading, the Dow Jones Industrial Average fell 12.26, or 0.1 percent, to 10,447.37. The Standard & Poor’s 500 Index slipped 3.57, or 0.3 percent, to 1,218.02. The Nasdaq Composite Index closed down 6.83, or 0.3 percent, at 2,141.07.
