Stock index futures slipped on Thursday following data that showed the number of people filing new claims for jobless benefits rose more than expected last week.

S&P 500 futures were off 0.4 points, but 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 were up 20 points, and Nasdaq futures slid 3.75 points.
