Answer:
The securities should a risk-averse investor purchase if the investment will be held in isolation is A because It has the lowest coefficient of variation.
Explanation:
We use the co-efficient of variation to calculate the risk level of the given stocks. The coefficient of variation is the measurement of risk of return.
A B C D E
Expected Returns 7% 10% 12% 25% 18%
Standard Deviation 2% 18% 15% 23% 15%
Use Following Formula to Calculate coefficient of variation.
Coefficient of variation = ( Volatility / Expected Return ) x 100
As Standard Deviation represent the volatility.
Coefficient of variation = ( Standard Deviation / Expected Return ) x 100
A. Coefficient of variation = ( 2% / 7%) x 100 = 28.57%
B. Coefficient of variation = ( 18% / 10%) x 100 = 180%
C. Coefficient of variation = ( 15% / 12%) x 100 = 125%
D. Coefficient of variation = ( 23% / 25%) x 100 = 92%
E. Coefficient of variation = ( 15% / 18%) x 100 = 83.33%
