More earnings jitters push stocks lower to end week

Concerns that corporate earnings will show no signs of an economic recovery kept many traders out of the market today and inspired those who did wade in to send stocks lower. The S&P 500 capped its fourth straight weekly decline and the Dow Jones industrial average fell 37 points, or 0.5 percent, to close at 8,147 as New York Stock Exchange volume fell to the lowest level since January, according to Bloomberg News.

Energy stocks were among the Dow's biggest losers, as Chevron (CVX) fell 2.7 percent and ExxonMobil (XOM) dropped 1.3 percent. Economic pessimism has pushed oil prices lower in recent weeks.
