April 22 (Reuters) - U.S. stocks slipped in choppy trading on Wednesday with traders focusing on earnings, as declines including in Boeing and Chipotle outweighed gains in McDonald's and Coca-Cola.
Boeing fell 1.7 percent to $150.77 after reporting revenue that fell short of expectations, while Chipotle fell 7.6 percent to $639.98 a day after it reported the slowest same-restaurant sales growth in five quarters.
Of the S&P 500 companies that have reported so far this earnings season, 71.9 percent posted earnings above analyst expectations. However, just 42.1 percent have beaten revenue expectations, compared with a 58 beat over the last four quarters.
