S&P CoreLogic Case-Shiller Indices
The S&P CoreLogic Case-Shiller Indices published by S&P Dow Jones Indices use the CoreLogic Case-Shiller HPI methodology to track changes in the value of the residential real estate market on a monthly basis. This family of indices consists of a national home-price index (see below), a 20-city composite index, a 10-city composite index and 20 individual metro-area indices. The S&P CoreLogic Case-Shiller U.S. National Home Price Index – calculated on a quarterly basis – is a broad composite of single-family home price indices for the nine U.S. Census divisions.
The S&P CoreLogic Case-Shiller Indices are also published to public markets as a benchmark for financial instruments on home prices. The S&P CoreLogic Case-Shiller Indices are utilized as the basis for the CME futures on the U.S. residential housing market, which is an important tool to manage risk in the $16 trillion U.S. housing market.
CoreLogic, together with Moody’s Analytics, offers the Case-Shiller Home Price Index Forecasts to provide clients with enhanced home-price forecasting capabilities. Moody’s Analytics U.S. macroeconomic and regional economic models are used to forecast CoreLogic Case-Shiller Indexes under alternative regulator-defined economic scenarios – including oil price shocks, financial market distress, dollar devaluations and others. This provides strategic planners critical information about how economic stresses could affect future housing prices – and has become a vital part of successful risk management and strategic planning.
CoreLogic Case-Shiller Home Price Forecaster
The Home Price Forecaster report gives originators, servicers and investors a low-cost method of validating the direction of area property values when reviewing appraisals, BPOs or a distressed loan. This report targets the five-year history and two-year forecast of home price trends on a unique property-by-property basis. It presents and graphs property trend data, population, and average real estate values.
When property information is limited or a loan originator wants a ballpark estimate of a loan applicant's home value before ordering an expensive appraisal, this interactive indexed property value computes a value estimate based on information you provide.
The CoreLogic® Case-Shiller Indexes® are calculated from single-family-home repeat-sales data, an approach developed in the 1980s by economists Karl Case and Robert Shiller. Case created a method for comparing repeat sales prices of the same homes, then worked with Shiller – who was researching behavioral finance – to develop a repeat-sales measurement index. Weiss, one of Shiller’s graduate students at the time, persuaded them to form a company, Case Shiller Weiss, to produce the index and sell the information to the markets.
The information management company Fiserv bought Case Shiller Weiss in 2002 and together with S&P Dow Jones Indices developed the tradable indices which are now commonly known as the S&P CoreLogic Case-Shiller Indices. CoreLogic acquired Case-Shiller from Fiserv in 2013 – and continues to serve Case-Shiller clients, Standard & Poor’s, and Moody’s Analytics.
Unlike methods using an average or median of all sales in a given market, CoreLogic® Case-Shiller Indexes® measure price changes between transactions on the same individual homes—comparing apples to apples, as it were. CoreLogic Case-Shiller analysts carefully validate the results to eliminate unrealistic volatility due to inconsistent or erroneous data.
The CoreLogic Case-Shiller Indexes have also been selected as the basis for the first exchange-traded derivatives in the U.S. residential housing market.

The Science of Repeat Sales
CoreLogic® Case-Shiller Indexes® use the repeat sales method for index calculation, analyzing data on single-family properties that have two or more recorded sales transactions.
Changes in housing types and sizes or physical characteristics are specifically excluded from the calculations to avoid affecting the index value incorrectly.
The principal variable used in index calculations is the price change between two arms-length sales of the same single-family home. For each sales transaction, a search is conducted to acquire information on any previous sale of the same property. If an earlier transaction is found, the two are paired and considered a “repeat sales transaction.”
Each sales pair is examined to eliminate factors that might distort the calculations, including:
- Non-arms-length transactions (e.g., transfers between family members)
- Transactions in which the property type designation has changed
- Any suspect data
Sales pairs with approved data are aggregated with all other sales pairs found in a particular Census division, state, metro area, county or zip code market to independently calculate each Case-Shiller model. The national index is a composite of the Case-Shiller Census division indexes.
Different weights are assigned to different changes in home prices, based on their statistical distribution in that geographic region. The weighting schemes include:
Smaller weights are assigned to homes that appear to have changed in quality or to sales that are not otherwise representative of market price trends.
High Turnover Frequency
Homes that sell more than once within six months are excluded from the calculation of any index.
Time Interval Adjustments
Longer sales pair intervals are assigned less weight than pairs with shorter intervals.
Initial Home Value
Each pair is assigned a weight equal to the first sale price.
Both price anomalies and longer time intervals can indicate physical changes to a home. High turnover frequency and shorter intervals can indicate that the transaction is not at arms-length, precedes or follows the property’s redevelopment, or is fraudulent. The index then tracks the aggregate/average value of all homes in the market.
