NEW YORK, Oct 14 (Reuters) - U.S. stock index futures trimmed gains on Thursday after data showed applications for unemployment insurance rose unexpectedly in the latest week.
S&P 500 futures rose 2.5 points and 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 gained 10 points and Nasdaq 100 futures added 4.5 points.
Futures were trading higher after a lingering U.S. dollar weakness pointed to increased demand for equities.
