1. a. Return of stock A = 8%
Return of stock B= 11%
b. Standard deviation of stock A = 10%
Standard deviation of stock B = 15%
D. Coefficient of variation (CV)= standard deviation/Return.
CV of A = 10/8= 1.25
CV of B = 15/11= 1.36
Coefficient of variation the lower the better. Stock A provides a better risk-return profile.
2. Stock C:
the standard deviation of 20%
the beta of 1.20.
Stock D:
the standard deviation of 16%
the beta of 1.44.
Total risk= systematic risk+unsystematic risk
Stock D has more systematic risk as its beta is higher.
Stock C is more total risk as its standard deviation is
higher.
Stock C is more risker due to its total risk.
