Risk Definition
Business Risk
Major uncertainties in the economy and how projects might be affected by these uncertainties.
Systematic Risk
Unsystematic Risk
Credit Risk
Risk of loss due to inability to repay a loan or failure to adhere to debt agreements.
Foreign Exchange Risk
Risk that particular currency loses its value relative to another currency.
Interest Rate Risk
Risk that a change in market interest rates can significantly reduce value of an investment.
Market Risk
Risk that value of an investment will change because overall market performance.
Industry Risk
Risk that the industry’s performance may negatively affect the investment of a company.
Political Risk
Risk that political actions and government rules and regulations will affect the performance of an entity and its investments.
Value at Risk (VaR)
The maximum loss within a given period of time and given a specified probability level (level of confidence).
Rate of Return
Rate of Return Formula
= Income / Average Investment Income
Relationship between Risk & Return
Standard Deviation
Statistical measure of variability or tightness of a distribution of outcomes around a central measure, the expected return.
Coefficient of Variance (CV)
Measures the relative risk per expected return.
= Standard deviation / Expected return
Diversification
Capital Asset Pricing Model (CAPM)
Capital Asset Pricing Model (CAPM) Formula
R = RF + β(RM − RF )
R = Expected return RF = Risk free rate of return RM = Market Rate (RM − RF ) = Market risk premium β = Beta coefficient, systematic (undiversifiable) risk
Beta Analysis
β > 1 High risk multiplier of stock price, highly volatile
β < 1 Low risk multiplier of stock price, less volatile
β = 1 Market & stock price move perfectly to changes in market
β = 0 No correlation of stock & market price
β < 0 Stock price moves inversely with that of the entire market
Yield Curve
Plots the interest rate of bonds that have equal credit quality at a set period of time, but differing maturity dates.
What are the three main patterns created by the interest rate term structure?
Common measures of Risk
Individual: expected return & standard deviation
Portfolio: covariance & correlation
Correlation
Statistical measure of the degree in which two investments move in relationship to each other.
