The expected return from investing in a security over some future holding period is an estimate of the future outcome of this security. Risk is an important concept in financial analysis, especially in terms of how it affects security prices and rates of return. Investment risk is associated with the probability of low or negative future returns. The riskiness of an asset can be considered in two ways: (1) on a stand-alone basis, where the assets cash flows are analyzed all by themselves, or (2) in a portfolio context, where the cash flows from a number of assets are combined and then the consolidated cash flows are analyzed. In a portfolio context, an assets risk can be divided into two components: (1) a diversifiable risk component, which can be diversified away and hence is of little concern to diversified investors, and (2) a market risk component, which reflects the risk of a general stock market decline and which cannot be eliminated by diversification, hence does concern investors. Only market risk is relevant; diversifiable risk is irrelevant to most investors because it can be eliminated.
