U.S. stock index futures trimmed gains on Thursday after data showed applications for unemployment insurance fell modestly in the latest week, while the number of people still drawing benefits unexpectedly rose.

S&P 500 futures rose 0.8 point 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 gained 4 points, and Nasdaq 100 futures added 2 points.
