Answer:
The Sharpe ratios for the market portfolio and portfolio A is 0.1677 and 0.2 respectively
Explanation:
The computation of the Sharpe ratio is shown below:
= (Expected Rate of Return - Risk-free rate of return) ÷ (Standard Deviation)
For Market portfolio, it would be
= (12.2% - 7%) ÷ (31%)
= 5.2% ÷ 31%
= 0.1677
For portfolio A, it would be
= (11% - 7%) ÷ (20%)
= 4% ÷ 20%
= 0.20
Simply we apply the Sharpe ratio formula in which the risk-free rate of return is deducted from the expected return and the same is divided by the Standard Deviation
