Question
The benchmark bond being assessed by Holly is most likely:
Answer Choices:
A. undervalued by $3.69
B. overvalued by $2.90
C. overvalued by $3.75
Explanation
There are two approaches to valuation of the bond.
Approach 1: Bootstrap the missing spot rates:
The two-year spot rate can be derived using the one-year spot rate (2.3%) and two-year
par rate (3.14%) as follows:
S2 = 3.15%
Likewise, the three-year spot rate can be calculated using the one-year spot rate (2.3%),
the two-year spot rate derived above (3.15%), and the three-year par rate (4.35%):
S3 = 4.42%
Having derived the relevant spot rates, Holly can now value the three-year, 6% benchmark
bond discounting the future cash flows using the spot rates:
Approach 2: Use the three-year par rate (4.35%) as the yield and use the standard TVM
keys:
N=3; I/Y = 4.35%; PMT = 6; FV = 100; CPT PV = $104.55
Note the difference in value is due to rounding error in calculating individual spot rates.
The bond is trading at $108.30, and is therefore overvalued by $3.75.
