Crude prices took a break from their recent ascent Tuesday, declining in New York after Goldman Sachs said it would advise taking profits. Oil ended the last session at a record price above $93 a barrel, the latest in a string of new all-time highs. Recently, though, crude for December delivery was down $1.86 to $91.67. At the same time, reformulated gasoline was losing 3 cents to $2.30 a gallon, and heating oil was weaker by 1 cent to $2.45 a gallon. Natural gas went against the trend and rose 12 cents to $8.09 per million British thermal units. Stocks in the energy sector were sharply lower. The Philadelphia Stock Exchange Oil Service Sector Index was dropping 2.5%, and the Amex Oil Index was slumping 2.4%. Oil-services firms Halliburton ( HAL) and Schlumberger ( SLB) both lost more than 2%, as did refiner Valero ( VLO). Integrated majors ConocoPhillips ( COP) and Exxon Mobil ( XOM) were down 1.7% and 1.9%, respectively, and Chevron ( CVX) gave back nearly 3%.
