House price appreciation impacts stock performance, affecting value-growth premium.
The study looked at why some types of companies do better in certain areas. They found that in places where house prices have gone up a lot, companies that are considered good deals (value firms) tend to do better compared to fast-growing companies (growth firms). This connection between house prices and company performance supports the idea that investing in value firms can be a good strategy. The study also showed that high house prices can hurt growth firms, but not help value firms. This relationship between house prices and company performance was still strong even after considering other reasons why some companies do better than others.
