Home prices in August rose from a year earlier but weakened from the month before. The Standard & Poor’s/Case-Shiller Home Price Indices shows the 10-City Composite up 2.6 percent and the 20-City Composite up 1.7 percent from August 2009. The 20-city index has gained 6.7 percent from its bottom in April 2009 but is down 28 percent from its July 2006 peak. Month-over-month, the 10-City Composite was down 0.1 percent and the 20-City Composite was down 0.2 percent. David M. Blitzer, chairman of the index committee at Standard & Poor’s, said it was a disappointing report that indicates slowing growth after consistent gains since prices hit their bottom in the spring of last year.
