With the concept of above metioned portfolio concept , the minimumvariance portfolio will formed as
Portfolio combination | |||
Case | Portion in VZ | Portion in T | Standard Deviation |
1 | 0.1 | 0.9 | 0.0176 |
2 | 0.2 | 0.8 | 0.0140 |
3 | 0.3 | 0.7 | 0.0108 |

10 | 1 | 0 | 0.0005 |
Clearly indicate that case 10 , maximum portion of investment in VZ will lead to minimum risk .
So, all investment is done on 17 jan 2017 in VZ shares at price of $ 49.46 /shares
No of shares = $1,000,000 / $ 49.46 = 20218.35 = 20218 shares
Answer b) As on 23 june 2017 , price of VZ share =$43.26
Value of portfolio = 20218 * $ 43.26 =$ 874630.68
Return = $ 874630.68 - $1,000,000 = -$125369
Return % = -12.54 %
