NEW YORK (AP) — Stocks are edging higher on Wall Street and oil prices are falling for the first time in a week, even as heavy fighting in the Middle East again threatened to slow the global flow of oil. The S&P 500 inched up 0.1% early Friday. The Dow Jones Industrial Average rose 62 points, and the Nasdaq composite slipped 0.1%. All three indexes are still on track to finish the week lower. After shooting to $102 per barrel a day earlier, Brent crude fell 2.6%. Treasury yields moved lower. European markets were higher and Asian markets closed lower.
