What components does the CAPM Model consist of?

The Capital Asset Pricing Model (CAPM) is a fundamental financial model used to determine the expected return on an investment based on its systematic risk. The components of the CAPM consist of three key elements: the risk-free rate, beta, and the market risk premium.

1. The risk-free rate represents the return expected from an investment with zero risk, usually associated with government securities such as Treasury bonds. This component serves as a baseline for evaluating potential returns from other investments.

2. Beta measures the volatility or systemic risk of a security relative to the overall market. It indicates how much the security's price is expected to move in relation to market movements. A beta greater than one suggests that the security is more volatile than the market, while a beta less than one indicates less volatility.

3. The market risk premium is the additional return expected by investors for taking on the higher risk of investing in the stock market over the risk-free rate. It is calculated as the expected market return minus the risk-free rate, reflecting the compensation investors require for the additional risk.

Together, these components enable investors to estimate the expected return on an asset and help in making informed investment decisions based on the risk-reward profile of various securities. Understanding this model is crucial for
