US STOCKS SNAPSHOT-Futures briefly add losses after PCE data

NEW YORK Aug 4 (Reuters) - U.S. stock index futures briefly added losses on Tuesday following a mixed report on June personal consumption and expenditures.

* While consumer spending rose slightly more than expected in June, personal income declined by a greater-than-expected 1.3 percent, the biggest decrease since January 2005, the Commerce Department said. For details, see [ID:nN03524993]

* S&P 500 futures SPc1 fell 6.50 points and were below 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 DJc1 shed 58 points, and Nasdaq 100 NDc1 futures were down 10.75 points. (Reporting by Ellis Mnyandu; Editing by Padraic Cassidy)
