Energy companies led a decline on the stock market as crude oil continues to tumble. The price of oil dropped another 5 percent Monday to $46 a barrel. That's far below its recent peak of more than $100 a barrel last June. The slump means much lower profits for energy companies, even though consumers benefit by paying less for gas.
