Homebuilding stocks are feeling the bite of higher mortgage rates
The S&P 500 Homebuilding Index fell 3.2% in September due to rising mortgage rates (7.5%) and weak revenues at Lennar (LEN) and KB Home (KBH). Home Depot (HD) and Lowe's (LOW) stocks dropped 11% and 8.5%, respectively, as building activity slows. Mortgage rates surged over half a point in two weeks, affecting sales and homebuyer demand.
