The Dow Jones Industrial Average enjoyed its best day in about four months as a rally in shares of retailing giant Walmart Inc. (WMT) and an apparent easing of China-U.S. trade tensions helped to support a broad rally on Wall Street. The Dow (DJIA) gained about 400 points, or 1.6%, at 25,559, registering its best one-session rise since April 10, the S&P 500 index (SPX) rose about 22 points, or 0.8%, at 2,840.
