U.S. stock indexes on Wednesday fought to climb as the Dow attempted to notch a sixth consecutive advance after China exempted some American goods from coming tariffs, signaling some further easing in tensions between Beijing and Washington on international trade. The Dow Jones Industrial Average /zigman2/quotes/210598065/realtime DJIA -0.95% was flat at 26,900, with a sixth straight gain matching the blue chips longest win streak since the period ended June 10. The S&P 500 index /zigman2/quotes/210599714/realtime SPX -0.39% edged less than a point lower to 2,977, while the Nasdaq Composite Index /zigman2/quotes/210598365/realtime COMP -0.83% advanced less than 0.1% to 8,089. China said Wednesday that higher tariffs wouldn't be levied against some U.S. imports for a year, starting Sept. 17, and that it would review more goods for exemption. Stocks also climbed as yields for the 10-year Treasury rate gained to 1.75%, implying that investors were shifting out of the safety of government bonds in favor of riskier stocks.
