By STAN CHOE (AP Business Writer) NEW YORK (AP) — Wall Street limped to the finish line of its third losing week in a row on Friday. The S&P 500 barely budged as it ended the week with a loss of more than 2%, like other U.S. indexes. It edged down by 0.65, or less than 0.1%, to 4,369.71. The Dow Jones Industrial Average added 25.83 points, or 0.1%, to 34,500.66, and the Nasdaq composite slipped 26.16, or 0.2%, to 13,290.78. August has been rough for the stock market, which has given back more than a quarter of the S&P 500’s torrid gains for the year’s first seven months.
