U.S. Stocks End Lower; Energy Stocks Sell Off

The U.S. stock market ended Monday's choppy session slightly lower, as the S&P 500 and Dow Jones Industrial Average retreated from fresh intraday records shortly after hitting them in morning trade. Trading on Wall Street was subdued after a big rally last week. Energy and materials sectors sold off amid falling oil prices, weighing on key benchmarks. The S&P 500 closed fractionally lower at 2,017.79. The Dow Jones Industrial Average lost 24.34 points, or 0.1%, to 17,366.18. The Nasdaq Composite finished the day up 8.17 points, or 0.2%, at 4,638.91.
