A Home Price Index (HPI) is a measure that tracks the changes in residential properties' prices over time. It provides an overview of the housing market's price trends, pegged to a base value rather than indicating average or median home prices in dollar amounts.
A trend is a general direction of movement that can be observed in various fields such as technology, economics, fashion, and finance. In the context of securities, a trend refers to the long-term price or trading volume movements, either up, down, or sideways, that characterize a particular market, commodity, or security, and also applies to interest rates and yields.
