Wall St. declines as earnings take center stage

Shares fell almost across the board, with energy stocks leading declines across 10 S&P 500 sectors and the consumer discretionary sector the lone gainer, helped by a 1.84-percent gain in Target . The negative start to the week, which includes earnings from 190 S&P 500 companies as well as a Federal Reserve policy meeting, put the brakes on a 9-percent rally that started on June 27. The S&P energy index fell 1.99 percent, its deepest percentage decline since late June.
