Wall Street falls on weak energy prices

U.S. stocks fell on Monday in light trading after a rally that drove the S&P 500 last week to its highest level in nearly five years and as falling oil prices hit energy shares.

The Standard & Poor's 500 Index shed 4.58 points, or 0.31 percent, to finish unofficially at 1,461.19. The Nasdaq Composite Index dropped 5.28 points, or 0.17 percent, to end unofficially at 3,178.67.
