Stocks were mixed at Thursday's opening bell on fears that fresh economic data are strong enough for the Fed to raise interest rates sooner than estimated. The U.S. economy grew more than expected in the third quarter. Gross Domestic Product rose 3.5% in September, estimates for expansion were at 3%. The number of Americans filing for jobless benefits rose by 3,000 last week to 287,000. That's more than economists were expecting but still near multi-year lows. Continuing claims increased 29,000 to 2.38 million in the week ended Oct. 18. Before the bell, DreamWorks (DWA) beat Wall Street's expectations with its quarterly results. The movie studio credited its success to its 'How to Train Your Dragon 2.' Avon (AVP) was lower at the open despite topping earnings estimates. The cosmetics maker said it is making progress on its 'turnaround journey.'
