Risk and Rates of Return: Stand-Alone Risk

Stand-alone risk is the risk an investor would face if he or she held only -Select-one portfolio one asset multiple assets Correct 1 of Item 1. No investment should be undertaken unless its expected rate of return is high enough to compensate for its perceived -Select-risk cost return Correct 2 of Item 1. The expected rate of return is the return expected to be realized from an investment; it is calculated as the -Select-combined sumstandard deviation weighted average Correct 3 of Item 1 of the probability distribution of possible results as shown below:

The -Select-widertighter broader Correct 4 of Item 1 an asset's probability distribution, the lower its risk.

The coefficient of variation is a better measure of stand-alone risk than standard deviation because it is a standardized measure of risk per unit; it is calculated as the -Select-correlation coefficient risk premium standard deviation Correct 5 of Item 1 divided by the expected return. The coefficient of variation shows the risk per unit of return, so it provides a more meaningful risk measure when the expected returns on two alternatives are not -Select-identical different correlated Correct 6 of Item 1.

Quantitative Problem: You are given the following probability distribution for CHC Enterprises:

State of Economy              Probability                Rate of return

Strong                              0.25                                20%

Normal                               0.45                                 8%

Weak                                  0.3                                  -4%
