Stock futures fell after stronger-than-expected economic news.
The weekly initial claims decreased by 23,000 to a seasonally adjusted 298,000 in the most recent week on expectations of 320,000 new claims.

The Commerce Department also released the newest estimate on the gross domestic product, the broadest measure of the economy, which grew at a 3.6 percent annual rate from July through September.
The reading was an upward revision from an earlier 2.8 percent estimate and the strongest growth rate since the first quarter of 2012.
Both the Dow Jones industrial average and S&P futures turned negative after the 8:30 am release of the two reports.
Recent better-than-expected labor-market data, and signs showing that the manufacturing sector and consumer spending are improving, have investors worried that the Federal Reserve could start reducing stimulus measures by paring back its $85-billion-a-month bond-purchase program as early as this month. The Fed’s easy-money policies have been credited for helping fuel the S&P 500’s 26% rise this year.
