Brent crude slipped to a low of $62.37, its lowest since July 2009, and was last down 0.6 percent at $63.30. WTI crude dropped below $59 a barrel and was last down 2.2 percent at $58.63 as worries persisted over a global supply glut and sluggish demand. Weak oil prices have added to worries about global demand and raised concerns about earnings for energy companies, with year-end tax selling putting more pressure on the group. U.S. stocks dipped on Friday, putting the benchmark S&P 500 on track to snap seven weeks of gains, after oil prices slumped further, Reuters reported. The S&P index had broken a three-day skid on Thursday, buoyed by upbeat retail sales figures and other data that pointed to a strengthening U.S. economy, but finished well off its session highs as oil prices slipped. The S&P energy sector was down 1.6 percent for the session and has shed more than 16 percent this year and is the worst performing of the 10 major S&P sectors. The Dow Jones industrial average fell 75.59 points, or 0.43 percent, to 17,520.75, the S&P 500 lost 7.98 points, or 0.39 percent, to 2,027.35 and the Nasdaq Composite dropped 8.80 points, or 0.19 percent, to 4,699.37. Declining issues outnumbered advancing ones on the NYSE by 2,097 to 724, for a 2.90-to-1 ratio; on the Nasdaq, 1,694 issues fell and 778 advanced for a 2.18-to-1 ratio. The benchmark S&P 500 index was posting 13 new 52-week highs and 31 new lows; the Nasdaq Composite was recording 24 new highs and 105 new lows. -- SPA 19:47 LOCAL TIME 16:47 GMT تغريد
