Janice V. bought a 5% $1000 20-year bond for $875. She received a semiannual dividend for 8 years, then sold it immediately after the sixteenth dividend for $950. What rate of return did she make per semiannual period, and per year (nominal)? The rate of return that she made per semiannual period is %. The rate of return that she made per year is [ ] %.
Expert Answer
For computing the semi annual rate of return, we need to use trail and error technique………….
(1) so let us assume 4% return semi annually.
CF = Cash flow = 1000 * 5% * 1/2 = 25
DF = Discounting factor ……….For 1 – 16 periods we take sum of all discounting factors. But for 16th period maturity value only that years DF is taken.
PV = CF * DF
Int Periods | CF | DF | PV |
1 to 16 | 25 | 11.6523 | 291.3074 |
16 | 950 | 0.533908 | 507.2128 |
798.5202 |
This present value of 798.52 is less than the 875. So let us decrease the discount rate to 3%
Int Periods | CF | DF | PV |
1 to 16 | 25 | 12.5611 | 314.0276 |
16 | 950 | 0.623167 | 592.0086 |
906.0361 |
Thus the required rate of return is between 3% and 4%. We use simple interpolation to find the rate which equals 875.
3 | 906 | ||
x | 875 | ||
4 | 799 | ||
(x -3) / (4 -3) = (875 – 906) / (799 – 906) | |||
x – 3 = – 31 / – 107 | |||
x – 3 = 0.29 | |||
X = 3.29 |
a) Thus semi annual rate of return = 3.29%
b) Effective annual rate = ( 1.0329)2 – 1 = 0.0669 or 6.69%
