Energy shares tank, dragging S&P 500 lower amid crude-oil tumble

Shares of a bevy of energy companies were getting hammered Monday, leading the S&P 500 lower as crude-oil prices continued a slide that took them below $39 a barrel Friday. Shares of Williams Companies Inc. and CONSOL Energy. both tumbled about 12%, while those for Chesapeake Energy Corp. were about 8.4% lower. West Texas Intermediate crude oil was seeing a 4% drop to $38.57 a barrel. That decline follows a 2.7% slide on Friday, which came after a meeting of the Organization of the Petroleum Exporting Countries resulted in its members deciding to keep crude production running at current levels despite crude oil's precipitous decline.
