Explanation / Answer

In the above question the investment period in portfolio is 3 years (1Jan 2004 - 31 Dec 2006)

Calculation of Accumulated value of Investment using Investment yield Method -

Since we invested $1000 at the beginning of 2004, 2005 and 2006, we find the balance of each contribution over the specified intervals of time and sum them together. So, denoting CyCy to be the year in which our contribution was made, we obtain:

C2004 = 1000(1.059) (1.063) (1.066) (1.055) = 1266.015

C2005 = 1000(1.06) (1.057) (1.056) = 1183.16

C2006 = 1000(1.067) (1.044) = 1113.95

(1266.015+1183.16+1113.95) = 3563.125

Accumulated Value of Investment under Investment Year Method = 3563.125

Calculation of Accumulated value of Investment using Portfolio Yield Method -

Initial Deposit by Olivia - $1000 (considered to be X)

Portfolio rates (2004 (R1) = 4.5, (2005 (R2) = 4.8, (2006 (R3) = 5.1

Accumulated Value = (1000*104.5/100) = 1045

                                      (1045*104.8/100) = 1095.16

                                      (1095.16*105.1/100) = 1151.01316

Accumulated value at the end of December 2016 using portfolio yield method is = 1151.01316
