Or otherwise, you can calculate the rate of return by the actual amount invested and
value changes:
To purchase the shares, you would have had to invest: $20,000/(1 − 0.04) = $20,833
25. Suppose you have $1000 to invest. The initial investment in Class A shares is $940
net of the front-end load. After 4 years, your portfolio will be worth:
$940 (1.10)4 = $1,376.25
Class B shares allow you to invest the full $1,000, but your investment performance net
of 12b-1 fees will be only 9.5%, and you will pay a 1% back-end load fee if you sell
after 4 years. Your portfolio value after 4 years will be:
$1,000 (1.095)4 = $1,437.66
After paying the back-end load fee, your portfolio value will be:
$1,437.66 .99 = $1,423.28
Class B shares are the better choice if your horizon is 4 years.
26.
a. After two years, each dollar invested in a fund with a 4% load and a portfolio
return equal to r will grow to:$0.96 (1 + r – 0.005)2
Each dollar invested in the bank CD will grow to:$1 (1.06)2
If the mutual fund is to be the better investment, then the portfolio return, r,
must satisfy:
0.96 (1 + r – 0.005)2> (1.06)2
0.96 (1 + r – 0.005)2> 1.1236
(1 + r – 0.005)2> 1.1704
1 + r – 0.005 > 1.0819
