What Is Beta? Beta is a measure of the volatility—or systematic risk—of a security or portfolio compared to the market as a whole. Beta is used in the capital asset pricing model (CAPM), which describes the relationship between systematic risk and expected return for assets (usually stocks).
Why is beta an appropriate measure of risk?
Beta is a measure of a stock’s volatility in relation to the overall market. If a stock moves less than the market, the stock’s beta is less than 1.0. High-beta stocks are supposed to be riskier but provide higher return potential; low-beta stocks pose less risk but also lower returns.
What is the beta for an average risk security?
The beta for an average risk security is 1; while a T-bill is considered risk-free with a beta of 0.
What is the beta of an average asset?
In finance, the beta (β or market beta or beta coefficient) is a measure of how an individual asset moves (on average) when the overall stock market increases or decreases. Thus, beta is a useful measure of the contribution of an individual asset to the risk of the market portfolio when it is added in small quantity.
What is systematic risk in finance?
