NEW YORK, April 30 (Reuters) - U.S. stock index futures were little changed on Tuesday as investors awaited a batch of economic data for a confirmation that the recent rally that has taken the S&P 500 to an another record close is solid.
The Federal Open Market Committee also begins its two-day meeting on monetary policy, with results scheduled to be announced on Wednesday. A recent slew of weak U.S. growth data has raised expectations the Federal Reserve will keep its pace of bond buying at $85 billion a month.
"With earnings season coming to an end, the focus is now on what the next market driving theme is," said Andre Bakhos, director of market analytics at Lek Securities in New York.
"The economic data, the comments from ECB and FOMC could all be the drivers, an additional confirmation to justify the levels we are at now. All of these factors come to play for us to break out to a whole new territory, above 1,600 (on the S&P 500)."
S&P 500 futures fell 1.9 points and were slightly below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration of the contract. Dow Jones industrial average futures fell 3 points while Nasdaq 100 futures added 0.75 point.
The S&P 500 index ended at an all-time high on Monday as growth-oriented stocks, including energy and technology, led the way to the index's sixth rise in the past seven sessions.
A positive finish to April would deliver a sixth straight month of gains. That would be the longest winning streak since September 2009 when the index rallied for seven straight months. The broad market index is up 1.6 percent for the month.
