Introduction to S&P/Case-Shiller Index
The S&P/Case-Shiller Index is a set of robust, reliable indices that measure the movement in residential home prices within the United States. Named after its developers, Karl Case and Robert Shiller, alongside Standard & Poor’s (S&P), this index provides a vital metric for investors, policymakers, and economists to gauge trends and changes in the housing market.
Detailed Definition
The index calculates price changes by comparing the prices of the same houses over time, thus theoretically eliminating the noise from changes in the types and sizes of homes sold. By emphasizing repeat sales, the S&P/Case-Shiller Index focuses on house price appreciation and depreciation, making it integral for constituents involved in real estate or economic forecasting.
