You Corp bonds are selling in the market for $1,020. These 10-year bonds pay 8% interest annually. If they are purchased at the market price, what is the expected rate of return?
Given Information –
Market Price of Corp Bond (PV) = $1,020
Time to Maturity (T) = 10 years
No of periods (n) = 10
Par Value/ Principal (P) = $1,000
Coupon Rate (r) = 8% per annum
Coupon Amount (C) = 1,000 * 0.08 = $80 per annum
Now,
Present Value (PV) = C/(1+r) + C/(1+r)2 + ………… + C/(1+r)n-1 + C/(1+r)n + [P/(1+r)n]
PV = {C * [(1+r)n -1]} / [r * (1+r)n] + [P/(1+r)n]
=> 1020 = {80 * [(1+r)10 -1]} / [r * (1+r)10] + [1000/(1+r)10]
Now, bond value is higher than par value which means that the return on bond is lower than 8% (coupon rate)
One way of solving for r is by hit and trial method by taking different values of r and try to find r which gives present value of cash flows equal to today’s market price i.e. $1,020
Rate (r) |
Bond Value / Market Price |
8.10% |
993.32 |
8.00% |
1,000.00 |
7.90% |
1,006.74 |
7.80% |
1,013.54 |
7.70% |
1,020.41 |
7.60% |
1,027.33 |
Here we see that at r= 7.70%, the bond value is nearest to current market price of $1,020. Further refining gives us the expected rate of return = 7.71%
Alternatively, r can be solved on calculator by putting the following values –
N= 10 PV = -1020 PMT = 80 FV=1000 CPT I/Y to give r= 7.71%
