US STOCKS SNAPSHOT-Futures trim losses after jobless data

NEW YORK Dec 30 (Reuters) - S&P 500 stock index futures trimmed slight losses on Thursday after new U.S. claims for unemployment benefits dropped more than expected last week to touch their lowest level in more than two years.

S&P 500 futures SPc1 shed 0.8 points and were slightly below 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 DJc1 lost 8 points, and Nasdaq 100 futures NDc1 rose 1.75 point.
