Energy shares drag on Wall Street as crude prices fall

Energy shares dragged Wall Street lower on Monday as crude prices fell further, while readings on the services sector and home sales came in below forecasts.

Brent crude oil LCOc1 fell below $85 a barrel and U.S. crude CLc1 dipped below $80 after Goldman Sachs slashed its price forecasts, citing abundant supply and lackluster demand. The S&P 500 energy sector .SPNY was down 2.6 percent, the largest decline among the top ten industry groups.

The fall in crude "is probably good for consumers but there are a number of energy stocks on the S&P 500 getting hit on concern about their earnings," said Bruce Zaro, chief technical strategist at Bolton Global Asset Management in Boston.

He said, however, the decline is "net positive" as it frees cash from consumers.

The Dow Jones industrial average .DJI fell 25.56 points, or 0.15 percent, to 16,779.85, the S&P 500 .SPXlost 6.47 points, or 0.33 percent, to 1,958.11 and the Nasdaq Composite .IXIC dropped 14.19 points, or 0.32 percent, to 4,469.52.
