"Both the housing sector and the economy continue to expand with home prices continuing to rise at about a 5% annual rate," says David M. Blitzer, Managing Director and Chairman of the Index Committee at S&P Dow Jones Indices. "The statement issued last week by the Fed after its policy meeting confirms the central bank's view that the economy will see further gains.
