Investors demand a risk premium based on the uncertainty caused by the basic business of the firm. Financial RiskUncertainty is introduced by the method by which the firm finances its investments. Borrowing requires fixed payments which must be paid ahead of payments to stockholders. The use of debt increases uncertainty of stockholder income and causes an increase in the stock’s risk premium. Liquidity RiskUncertainty is introduced by the secondary market for an investment. How long will it take to convert an investment into cash? How certain is the price that will be received? Investors increase their required rate of return to compensate for liquidity risk. Exchange Rate RiskUncertainty of return is introduced by acquiring securities denominated in a currency different from your own. Changes in exchange rates affect the investors return when converting an investment back into the “home” currency. Country RiskPolitical risk is the uncertainty of returns caused by the possibility of a major change in the political or economic environment in a country. Individuals who invest in countries that have unstable political-economic systems must include a country risk-premium when determining their required rate of return Total RiskRisk Premium is a function of Business Risk, Financial Risk Liquidity Risk Exchange Rate Risk Country Risk Measures of RiskVariance of rates of return Standard deviation of rates of return Coefficient of variation of rates of return (standard deviation/means) Covariation of returns with the market portfolio (beta) Sources of RiskBusiness Risk Financial Risk Liquidity Risk Exchange Rate Risk Country Risk (Expected)Relationship BetweenRisk and ReturnFigure 1.4Market Portfolio RiskThe market risk premium for the market portfolio (contains all the risky assets in the market) can be computed:RPm = E(Rm)- NRFR where:RPm = risk premium on the market portfolioE(Rm) = expected return on the market portfolioNRFR = expected return on a risk-free asset1.14
