TerraIndex™ HPI, released weeks ahead of competitors, shown to report similar trends

May 8, 2023

BELLEVUE, WA – Since Quantarium first began publishing its TerraIndex™ HPI more than three months ago, the results have shown that the company’s national HPI is returning results that are similar to other national HPIs – but a lot faster.

The TerraIndex™ HPI Report is like other national HPI-based reports that track house prices and trends, such as the CaseShiller National Home Price Index and the Black Knight Mortgage Monitor Report. Along with the Zillow and the Core Logic indices, these approaches all use hundreds of millions of mortgage and public records and MLS data records as the foundation for their reports.

As the data table and the chart below illustrate, all five national home price indices are showing a similar pattern, namely that prices are increasing at a slower and slower rate each month since December 2022. Quantarium, CaseShiller and Black Knight show somewhat similar results in the rate of national price changes each month.

On a non-seasonally-adjusted month-over-month basis, all five HPI providers are capturing the market shift that happened from January to February 2023, when home prices broke the depreciation trend that started in the summer of 2022 – see the chart below. Quantarium’s month-over-month HPIs seem to be somewhat closer to Case-Shiller for the three months combined.

But, while the general trends are similar, the reporting date for indices each month is substantially different. For example, in reporting its December 2022 results, Case-Shiller waited until February 28, 2023 – a full two months after the close of December – to issue its report. For the same month, Quantarium issued its report on January 11, 2023, just 11 days after the close of the month. These detailed differences for the three months analyzed in this report are illustrated in the chart below. In fact, Quantarium’s three-month rolling average time lag is nine days. The average monthly time lag for a full year is expected to be around ten days.

About TerraIndex™ HPI

The TerraIndex™ Home Price Index (HPI) is based on the proprietary Quantarium Valuation Model (QVM) value estimates for more than 100 million residential U.S. homes. QVM has been tested extensively in the last five years by some of the most trusted third-party AVM testing agencies in the U.S. and has been consistently ranked at the top for both Accuracy and Hit Rate performance metrics. QVM was also recently approved by Fitch Ratings for Wall Street transactions. You can read the announcement here.

According to John Smintina, Ph.D., Chief Analytics Officer and Quantarium Co-Founder, Quantarium can report results sooner than other indices because QVM re-computes the estimated values for the entire national footprint on a weekly basis, along with HPIs at various geography levels – from State, County, CBSA, down to Zip Code and Census Tract. Furthermore, the HPIs produced on a given date are based on proprietary valuation models which include over 90% of all sales transactions that will have been eventually reported through a four-week rolling period ending that date, taking advantage of Quantarium’s industry-leading Data Services Platform (QDSP) to reduce the processing time lag to an absolute minimum. That allows TerraIndex™ HPI to provide the most current market insights, being weeks faster than most other housing indices in the U.S.

The report for a given month is usually available on the second Wednesday of the following month. For example, HPIs for the month of April 2023 will be released on Wednesday, May 10.
