Capital Asset Pricing Model (CAPM)
Save
The Capital Asset Pricing Model (CAPM) is a widely used model in finance for pricing risky assets and calculating the expected return of an asset. It is a fundamental concept in modern portfolio theory and is used by investors and financial professionals to make investment decisions.
What is CAPM?
CAPM is a model that describes the relationship between the expected return of an asset and its systematic risk. Systematic risk, also known as market risk or non-diversifiable risk, is the risk that affects the entire market or a large segment of it and cannot be diversified away through diversification. CAPM assumes that investors are rational and risk-averse and that they require a higher expected return for taking on more systematic risk.
The CAPM formula is as follows:
Expected Return = Risk-Free Rate + Beta * (Market Return - Risk-Free Rate)

What is CAPM?
CAPM is a model that describes the relationship between the expected return of an asset and its systematic risk. Systematic risk, also known as market risk or non-diversifiable risk, is the risk that affects the entire market or a large segment of it and cannot be diversified away through diversification. CAPM assumes that investors are rational and risk-averse and that they require a higher expected return for taking on more systematic risk.
The CAPM formula is as follows:
Expected Return = Risk-Free Rate + Beta * (Market Return - Risk-Free Rate)
- Expected Return: The expected return of the asset over a given holding period.
- Risk-Free Rate: The return on a risk-free investment, such as a government bond.
- Beta: A measure of the asset's systematic risk. A beta of 1 indicates that the asset's return moves in line with the market, while a beta of less than 1 indicates that the asset's return is less volatile than the market. A beta of greater than 1 indicates that the asset's return is more volatile than the market.
- Market Return: The expected return of the overall market or a market index.
Assumptions of CAPM
CAPM is based on several assumptions:
- Investors are rational and risk-averse.
- Investors have access to perfect information.
- All investors have the same expectations about the future.
- There are no transaction costs or taxes.
- The market is in equilibrium.
Applications of CAPM
CAPM is used for a variety of applications in finance, including:
- Asset Pricing: CAPM can be used to determine the fair value of risky assets by calculating their expected return.
- Portfolio Optimization: CAPM can be used to construct portfolios that minimize risk for a given level of expected return.
- Performance Evaluation: CAPM can be used to evaluate the performance of investment managers by comparing their returns to the expected return as determined by CAPM.
Limitations of CAPM
CAPM is a useful tool for understanding the relationship between risk and return, but it has some limitations:
- Assumptions: The assumptions of CAPM are not always realistic in practice.
- Estimation Errors: The parameters in the CAPM formula, such as beta and the risk-free rate, are estimated and subject to error.
- Changing Market Conditions: The relationship between risk and return can change over time, which can affect the accuracy of CAPM.
