Discuss risk from the perspective of the Capital Asset Pricing Model (CAPM).
The Capital Asset Pricing Model, or also known as CAPM, can be employed to calculate the suitable required rate of return for an investment project given its degree of risk as calculated by beta (β). A project's beta denotes its degree of risk relative to the whole stock market. In the CAPM, while the beta term is multiplied through the market risk premium term, the result is the additional return over the risk-free rate that investors demand from that individual project. High-risk or high-beta projects comprise high required rates of return, and low-risk or low-beta projects comprise low required rates of return.
