Before seasonal adjustment, the U.S. National Index posted a 0.8% month-over-month increase, while the 10-City and 20-City Composites both posted increases of 0.8% and 0.9% respectively in January. After seasonal adjustment, the U.S. National Index posted a month-over-month increase of 1.2%, and the 10-City and 20-City Composites both posted increases of 1.2% as well. In January, 19 of 20 cities reported increases before seasonal adjustment, and all 20 cities reported increases after seasonal adjustment.

“The strong price gains that we observed in the last half of 2020 continued into the first month of the new year. In January 2021, the National Composite Index rose by 11.2% compared to its year-ago levels,” says Craig J. Lazzara, Managing Director and Global Head of Index Investment Strategy at S&P DJI. “The trend of accelerating prices that began in June 2020 has now reached its eighth month and is also reflected in the 10- and 20-City Composites (up 10.9% and 11.1%, respectively). The market’s strength is broadly-based: all 20 cities rose, and all 20 cities gained more in the 12 months ended in January 2021 than they had gained in the 12 months ended in December 2020.
