Stock index futures pared gains on Wednesday after the ADP employment report showed a worse-than-expected 473,000 private sector jobs were cut in June.

S&P 500 futures rose 3.3 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 21 points, and Nasdaq 100 futures added 6.25 points.
