Stock index futures briefly trimmed gains on Wednesday after news euro zone finance officials were examining ways of delaying parts or even all of a second bailout for Greece, while still avoiding a disorderly default.

S&P 500 futures were up 5.5 points and 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 rose 30 points, and Nasdaq 100 futures gained 12.50 points.
