Calculating the beta of a portfolio.
The CAPM formula is: Cost of Equity (Ke) = rf + β (Rm – Rf) CAPM establishes the relationship between the risk-return profile of a security (or portfolio) based on three variables: the risk-free rate (rf), the beta (β) of the underlying security, and the equity risk premium (ERP). CAPM calculates the cost of equity (Ke), or expected return ...
