Capital Asset Pricing Model
Save
The Capital Asset Pricing Model (CAPM) is a mathematical model that describes the relationship between the risk and expected return of an asset. It is used to determine the required rate of return for an asset, given its risk level. CAPM is a fundamental concept in finance and is used by investors and financial analysts to make investment decisions.
Assumptions of CAPM
CAPM is based on several assumptions, including:
- Investors are rational and risk-averse.
- Investors have access to perfect information and can borrow and lend at the risk-free rate.
- The market is efficient and there are no transaction costs.
- All assets are infinitely divisible.
CAPM Formula
The CAPM formula is as follows:
E(Ri) = Rf + βi(E(Rm) - Rf)
- E(Ri) is the expected return of the asset.
- Rf is the risk-free rate.
- βi is the beta of the asset, which measures the asset's systematic risk.
- E(Rm) is the expected return of the market.
Applications of CAPM
CAPM is used in a variety of applications, including:

- The assumptions of CAPM are often unrealistic. In reality, investors are not always rational and risk-averse, and they may not have access to perfect information.
- CAPM does not take into account all factors that affect the return of an asset. Other factors, such as liquidity and inflation, can also affect the return of an asset.
- CAPM is a static model. It does not take into account changes in the market or the economy.
