Capital Asset Pricing Model (CAPM)
The Capital Asset Pricing Model (CAPM) is a financial tool used to estimate the expected return on an investment based on its risk. It considers two types of risks: systematic risk and unsystematic risk. Systematic risk is the risk related to the overall market, while unsystematic risk is specific to a particular company or industry and can be reduced through diversification.
The CAPM formula is:
Expected Return = Risk-Free Rate + Beta * (Market Return - Risk-Free Rate)
The formula takes into account the risk-free rate, which represents the return on a risk-free investment, and beta, which measures the investment's sensitivity to market movements. The market return reflects the average return expected from all investments in the market.
By using the CAPM, investors can estimate the appropriate return they should expect for taking on a certain level of risk. However, it's important to note that the CAPM relies on certain assumptions that may not always hold true in practice.
In simpler terms, the CAPM helps investors determine how much return they should expect based on the riskiness of an investment compared to the overall market.
