Stocks end lower in choppy trading, on pace for weekly loss

Stocks closed lower in another day of choppy trading on Wall Street, on pace for a weekly loss after several days of declines. Losses in technology and retail stocks outweighed gains in communications and other sectors. The S&P 500 lost nearly 1% Wednesday after wavering between gains and losses. The Dow Jones Industrial Average and Nasdaq composite also lost ground. Bed Bath & Beyond lost almost a quarter of its value after announcing a major restructuring and a stock sale. Treasury yields rose and energy prices fell. The market closed August broadly lower after surging in July.
