Stock index futures fell on Friday as investors took profits a day after a powerful rally that propelled the S&P to close above its 200-day moving average for the first time since August.

On Thursday, the market soared 3 percent after a long-awaited agreement was struck to help contain the region's two-year debt crisis. The S&P 500 is up more than 13 percent this month, on pace for its biggest monthly gain since October 1974.

The head of Europe's bailout fund played down hopes of a quick deal with China to throw its support behind efforts to resolve the debt crisis but said he expects Beijing to continue to buy bonds issued by the fund.

S&P 500 futures fell 7.5 points and were 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 lost 61 points, and Nasdaq 100 futures fell 12.50 points.

Shorter-term indicators, tracking two to four-week shifts, remain overbought, with the S&P 500 nearing its next resistance between 1,290 and 1,300, said Robert Sluymer, an analyst at RBC Capital Markets LLC in New York.

We continue to believe near-term pullbacks in equities should be relatively shallow, given the bigger intermediate-term trend into year-end appears to be up for stocks.
