U.S. stock index futures fell on Monday after the market's best two-week run since 2009 as Germany's finance minister said a forthcoming European summit wouldn't yield a definitive solution to the region's debt crisis.

S&P 500 futures fell 1.8 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 dropped 21 points, and Nasdaq 100 futures were off 1.75 points.
