Introduction
The Capital Asset Pricing Model (CAPM) is a key economic tool used in valuing securities, focusing on expected returns relative to risk. It is based on the principle that investors will accept higher risk only if they anticipate higher returns. Consequently, a stock's price is determined by adding the risk premium to the risk-free rate, accounting for the additional risk taken.
The CAPM Formula
The formula for CAPM is:
Expected Return = Risk-Free Return + Beta × Market Risk Premium
In this equation, beta represents the general market risk, such as that on the New York Stock Exchange.
Understanding Beta
Beta is a measure of a stock's volatility compared to the overall market, which is assigned a beta value of 1.0. Stocks with a beta greater than 1.0 are considered more volatile, while those with less are deemed less risky. Beta plays a crucial role in CAPM, influencing the cost of capital and the present value of future cash flows.
Calculation of Beta
Beta is determined through linear regression analysis, comparing the returns of a portfolio with individual assets over a specific timeframe. The resulting downward-sloping line is known as the Security Characteristic Line. Beta values are commonly calculated by major brokerage firms and published in beta books, though access may be restricted for regular investors. However, platforms like Yahoo Finance also provide beta coefficients. A beta of 0.00 indicates a new stock with no historical performance data.
Conclusion
Beta is indispensable in assessing company valuation through CAPM, offering insights into investment risk and potential returns. By understanding beta, investors can make more informed decisions in the dynamic financial markets.
