What is the portfolio balance model?

The portfolio balance model is an economic theory that explains how investors allocate their assets among various financial instruments to achieve an optimal balance between risk and return. It suggests that the overall demand for financial assets is influenced by factors such as interest rates, wealth, and expected returns, leading to a dynamic adjustment of portfoliOS in response to changing economic conditions. This model helps to understand the relationships between asset prices and macroeconomic variables, guiding investors in their decision-making processes.
