The Capital Asset Pricing Model, or CAPM, calculates the value of a security based on the expected return relative to the risk investors incur by investing in that security.
To calculate the value of a stock using CAPM, multiply the volatility, known as “beta,” by the additional compensation for incurring risk, known as the “Market Risk Premium,” then add the risk-free rate to that value.
The formula for CAPM is as follows:
Expected return of the investment = the risk-free rate + the beta of the investment times the expected return on the market – the risk free rate which is the market risk premium.
For each additional increment of risk incurred, the expected return should proportionately increase.
If a security is found to have a higher return relative to the additional risk incurred, then the CAPM model suggests that it is a buying opportunity.
Like all valuation models, CAPM has its limitations since some assumptions it uses are idealistic.
For example, Beta coefficients are unpredictable, change over time, only reflect systematic risk rather than total risk.
Despite its shortcomings, this model is very popular for valuing securities.
