Keeping track of the commercial real estate market may be a bit easier thanks to an innovation announced by Standard & Poor’s earlier this month. The S&P/GRA Commercial Real Estate Indices (SPCREX) will measure changes in commercial real estate prices by property sector and geographic region, according to Standard & Poor’s. The indicator is composed of 10 commercial real estate indexes: a national composite, five geographic regions, including the Midwest, and four national property sectors.
