NEW YORK, Aug 25 (Reuters) - U.S. stock index futures rose on Tuesday after data showed home prices rose for a second straight month in June following nearly three years of decreases.
Futures were higher earlier after U.S. President Barack Obama nominated Ben Bernanke for a second term as Federal Reserve chairman.
S&P 500 futures rose 6.9 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 65 points while Nasdaq 100 futures added 10.25 points.
