NEW YORK, April 4 (Reuters) - U.S. stock index futures trimmed some gains on Thursday after data showed weekly jobless claims rose more than expected in the latest week.
S&P 500 futures rose 3.5 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 (DJI: ^DJI - news) industrial average futures added 26 points and Nasdaq 100 futures rose 11.25 points.
