Stock futures extended gains on Friday after Intel Corp raised its third-quarter revenue and gross margin expectations.

Futures were already trading higher after a better-than expected quarterly performance from computer maker Dell Inc boosted the technology sector.

S&P 500 futures rose 7.7 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 60 points and Nasdaq 100 futures added 19.75 points.
