Stock index future trimmed gains on Wednesday after a government report showed U.S. economic growth was a touch higher than previously estimated in the third quarter, but below expectations.

S&P 500 futures shed 0.2 point but were slightly 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 fell 2 points, while Nasdaq 100 futures fell 2.75 points.
