Probability | Return on market | Return on A |
0.2 | 18% | 16% |
0.3 | 12% | 14% |
0.5 | 10% | 11% |
Part a
Expected return is calculated using the formula:
E[R] = p1*R1 + p2*R2 + p3*R3
Expected return of market = E[RM] = 0.2*18% + 0.3*12% + 0.5*10% = 12.2%
Expected return on stock A = E[RA] = 0.2*16% + 0.3*14% + 0.5*11% = 12.9%
Part b
Coefficient of variation = CV = Standard deviation/Expected return
CV for market
Standard deviation of market = σM = 3.0265%, Expected rteun of market = E[RM] = 12.2%
Coefficient of variation for market = CVM = σM/E[RM] = 3.0265%/12.2% = 0.248073770491803
CV for stock A
Standard deviation of Stock A = σA = 2.0224%, Expected rteun of stock A = E[RA] = 12.9%
Coefficient of variation for stock A = CVA = σA/E[RA] = 2.0224%/12.9% = 0.15677519379845
