Stock index futures were little changed on Thursday as investors looked ahead to data that could shed light on the economy's health amid worries that global demand was slowing.
Equities have been pressured recently, with the S&P 500 down 3.2 percent so far this month. Investors said Wednesday's rally, which broke a three-day losing streak in stocks, may not be enough to overcome macroeconomic worries.
The preliminary estimate of first-quarter gross domestic product is due at 8:30 a.m. (1230 GMT) and is seen rising by 2.1 percent compared with the 1.8 percent rate previously estimated by the government.
Though the economy was seen expanding in the quarter despite sovereign debt woes, geopolitical tensions and natural disasters overseas, a weaker-than-expected reading could exacerbate concerns about global growth.
Weekly jobless claims are also on tap, with 400,000 initial claims expected, down from the 409,000 posted last week but still considered high.
S&P 500 futures rose 2.7 points and were slightly above 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 added 21 points and Nasdaq 100 futures were flat.
