US STOCKS-Futures flat ahead of claims, GDP data

NEW YORK, Dec 5 (Reuters) - U.S. stock index futures were little changed on Thursday, ahead of data on the labor market and economic growth that may help investors assess whether a wind-down of Federal Reserve stimulus is imminent.
* The S&P 500 has fallen for four straight sessions, shedding 0.8 percent, its longest losing streak since late September as recent economic data has cast some uncertainty over when the Federal Reserve will begin to trim its stimulus of $85 billion in monthly bond purchases.
* Many market participants expect the Fed to announce a cut in March. The Fed has said it would slow its stimulus program when certain economic measures meet its targets, including a decline in the U.S. unemployment rate.
* Economic data expected at 8:30 a.m. EST (1330 GMT) includes weekly initial jobless claims and a second estimate of third quarter gross domestic product.
* Economists surveyed by Reuters expect claims to show a total of 325,000 new filings compared with 316,000 in the prior week while GDP is expected to have grown an annualized 3.0 percent compared with 2.8 percent in the first estimate.
* S&P 500 futures slipped 0.9 point and were slightly below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures shed 9 points and Nasdaq 100 futures added 3.5 points.
* Later in the session at 10:00 a.m. (1500 GMT), October factory orders data is expected. Economists surveyed by Reuters expect a drop of 1.0 percent compared with a 1.7 percent rise in September.
* China Mobile Ltd, the country's largest mobile operator, has signed a long-awaited deal with Apple Inc to offer iPhones on its network, the Wall Street Journal reported on Thursday, citing an anonymous source familiar with the matter. Apple shares gained 1.4 percent to $573 in premarket trading.
* Aeropostale Inc slumped 8.7 percent to $8.55 before the opening bell after the apparel retailer forecast a much bigger-than-expected loss for the holiday shopping quarter.
* Costco Wholesale Corp's November same-store sales fell short of analysts' expectations, as lower gasoline prices and weak foreign currencies dampened a five percent increase in the company's monthly net sales.
* Retailers and telecoms led European shares lower and Asian markets were mostly down on concerns over the potential for an early winding down of equity-friendly U.S. monetary stimulus.
