U.S. stock index futures added to their gains on Friday following a better-than-expected read on the labor market.

According to the closely watched non-farm payrolls report from the U.S. Labor Department, 244,000 jobs were added in April, far more than had been anticipated. However, the unemployment rate rose to 9 percent from 8.8 percent where analysts expected the rate to remain steady.

S&P 500 futures rose 11.7 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 added 80 points and Nasdaq 100 futures rose 16.75 points.
