NEW YORK, Jan 12 (Reuters) - U.S. stocks fell on Monday, led by a decline in energy shares as oil prices fell further while concern grew ahead of the start of corporate earnings season.
Oil prices continued their downward march and weighed on equities. Brent was down more than 5 percent to $47.44 and U.S. crude down 4.6 percent at $46.13, as Goldman Sachs slashed its short-term price forecasts and Gulf producers showed no signs of curbing output.
The S&P energy index, the day's worst-performing S&P 500 sector, was down 2.7 percent.
