U.S. home prices rise slightly less than forecast

U.S. single-family home prices rose slightly less than expected on an annual basis in July, and the year-over-year gain was smaller than in the prior month, a survey showed on Tuesday. The S&P CoreLogic Case-Shiller composite index of 20 metropolitan areas rose 5 percent in July on a year-over-year basis, retreating from the 5.1 percent climb in June and short of the estimate calling for a 5.1 percent increase from a Reuters poll of economists.
