NEW YORK, Dec 11 (Reuters) - U.S. stock index futures advanced on Thursday, putting the S&P on track to rebound after a three-day drop as oil prices bounced and ahead of a flurry of economic data.
* The benchmark S&P index dropped more than 1 percent on Wednesday and has shed 2.4 percent over the past three sessions, it's worst run in two months, as weakness in oil prices has weighed heavily on the energy sector.
* Falling oil prices have added to worries about global demand and raised concerns about earnings for energy companies, with year-end tax selling putting additional pressure on the group. The sector is down 14.7 percent for the year and is the worst performing of the 10 major S&P sectors.
* Brent crude managed to climb back above the $65 mark but remained near five-year lows while U.S. crude rose 1.1 percent to $61.60.
* Investors await a trio of economic data reports at 8:30 a.m. EST (1330 GMT), including weekly initial jobless claims data, November retail sales and import prices for November. Initial claims are expected to show a reading of 295,000 while retail sales are expected to rise by 0.4 percent. Import prices are forecast to decline by 1.8 percent.
* The data may influence investors' expectations on whether the Fed will adjust its language to keep interest rates near zero for a "considerable time" when policymakers meet next week.
* Later in the session at 10:00 a.m. (1500 GMT), business inventories data for October is expected.
* U.S.-listed shares of Teva Pharmaceutical edged down 0.7 percent to $56 in premarket trade after the generic drugmaker forecast 2015 revenue below analysts' expectations.
* Lululemon Athletica lost 4.2 percent to $44.75 in premarket trading after the maker of yoga apparel posted quarterly results.
* Staples Inc jumped 11.4 percent to $16.50 and Office Depot climbed 8 percent to $7.26 before the opening bell after Activist investor Starboard Value LP disclosed stakes in both office-supply retailers in a move that could set up a potential merger.
* Staples was the most active stock on Nasdaq before the bell, with over 1.5 million shares traded, representing over 10 percent of its 10-day average. Volume of over 300 shares for Office Depot was about 4 percent of its 10-day average.
