The U.S. stock market ended Wednesday's choppy session lower with the main benchmarks breaking their four-day winning streak that sent the S&P 500 to record close above 1,900. Analysts attributed small losses to investors taking a breather after four consecutive days of gains. The benchmark S&P 500 traded in positive territory for the most of the session but gave up incremental gains and closed 2.13 points, or 0.1%, lower at 1,909.76. The Dow Jones Industrial Average lost 42.32 points, or 0.3%, to 16,633.05. The Nasdaq Composite dipped in and out of negative territory and ended the day down 11.99 points, or 0.3%, at 4,225.07.
