Examples of factors that lead to systematic risk include inflation, interest rate, economic cycles, etc. Coefficient beta is a measure of systematic risk and it is calculated by estimating a linear model where the dependent variable is the return vector of a stock and the explanatory variable is the return vector of a diversified local market index, such as SP500 (US), FTSE (UK), Ibovespa (Brazil), or any other. Beta values are examined for six diversification categories, and it is found that betas for unrelated diversifiers are significantly higher than those of other firms. If an investment has twice as much systematic risk as the market, it would have a beta of two. Bi = the systematic risk of security (beta). Examples of Systematic Risk. This relative measure of risk is called the ‘beta' and is usually represented by the symbol b. A value of 1.0 indicates that the asset is strongly correlated with the overall market, and can be expected to exhibit volatility very … Beta is an indirect measure which compares the systematic risk associated with a company’s shares with the systematic risk of the capital market as a whole.

Once the systematic risk of an investment is calculated, it is then divided by the market risk, to calculate a relative measure of systematic risk. As a measure of systematic risk, beta is used in numerous methods and tools of portfolio management and security analysis. The dynamic betas using the dynamic conditional correlation – generalized auto-regressive conditional heterosckedasticity (DCC-GARCH) model, indicate that real estate, financials, and basic materials are the high-risk industries. Another strategy for managing systematic risk is to pay attention to a stock’s beta value. Systematic risk, also called market risk, is risk that's characteristic of an entire market, a specific asset class, or a portfolio invested in that asset class. We investigate the impact of energy commodity uncertainties on the systematic risk of twelve industries in the US. In other words, according to CAPM, and in equilibrium, the expected return on any stock (portfolio) is equal to be the risk tree rate of return plus its beta times the risk premium (Rm – Rf) on the market portfolio. Just as the implicit volatility of an asset is revealed by an ordinary call option, the “implicit beta” of a stock would be revealed by the price of an option to exchange shares of stock for shares of a market index. Up or down swings in the market, known as volatility , are ultimately unpredictable.
