Stock index futures fell on Tuesday after the S&P 500 climbed to a 4-year high in the previous session as investors awaited factory orders data and minutes of the latest Federal Reserve meeting.

Wall Street had a strong start to the second quarter on Monday, with the S&P 500 marking its highest close since mid-May 2008. The Dow scored its highest finish since December 31, 2007, while the Nasdaq once again closed at levels not seen since late 2000.

The S&P 500's uptrend remains intact but is becoming advanced above its 75-day moving average, said Robert Sluymer, analyst at RBC Capital Markets LLC in New York. He said a potential rotation is beginning to develop from leading sectors in the first quarter toward lagging ones, notably cyclicals.

Consumer discretionary and technology growth stocks have led the S&P through Q1, but consumer leaders are showing very early technical indications of pausing, stalling, as other less extended, oversold areas of the market begin to rebound, Sluymer said.

S&P 500 futures dipped 2.7 points and were 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 lost 21 points, and Nasdaq 100 futures were flat.
