Stock index futures extended gains on Thursday after data showed first-time applications for jobless insurance fell more than expected in the latest week.

S&P 500 futures rose 5.2 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 industrial average futures gained 53 points and Nasdaq 100 futures added 9.75 points.
