NEW YORK, Feb 10 (Reuters) - U.S. stock index futures slightly pared losses on Thursday after new claims for unemployment benefits dropped more than expected last week to their lowest point in 2-1/2 years.
S&P 500 futures fell 6.5 points and were 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 tumbled 44 points, and Nasdaq 100 futures were off 16.75 points.
