Final answer:
The coefficient of variation (CV) measures the risk per unit of return for an investment. CV can be calculated by dividing the standard deviation of expected returns by the expected return and multiplying by 100. The CV for Stock X is 4.21% and for Stock Y is 2.31%.
Step-by-step explanation:
The coefficient of variation (CV) measures the risk per unit of return for an investment. To calculate the CV, divide the standard deviation of the expected returns by the expected return, and then multiply by 100 to get a percentage. For Stock X, the CV can be calculated as:
CVx = (Standard Deviation of Expected Returns for Stock X / Expected Return for Stock X) * 100
CVx = (0.4 / 9.5) * 100 = 4.21%
For Stock Y, the CV can be calculated as:
CVy = (Standard Deviation of Expected Returns for Stock Y / Expected Return for Stock Y) * 100
CVy = (0.3 / 13.0) * 100 = 2.31%
