Report bond prices to the nearest .01, dollar amounts to the nearest dollar, and returns or yields to the nearest basis point. You do not need to express bond prices in 1/32nd format.
Solution:-
Maturity of bond = 3Years
Coupon Rate = 8%
Coupon Amount = $ 80 (Assume Face Value to be $1000)
Yield to Maturity/Discounting rate = 5%
A. Quoted Price of Bond
Quoted price of a bond is a price at which bond is traded or sell in a market. Quoted price of a bond is calculated by discounting all the coupon payments and maturity value receive at the end of maturity period. Quoted Price is calculated as below:-
Price (B0) = Coupon Amount / (1+ytm)1 + Coupon Amount / (1+ytm)2 + Coupon Amount / (1+ytm)3 + Maturity Value / (1+ytm)3
= $80 / (1+ 0.05)1 + $80 / (1+ 0.05)2 + $80 / (1+ 0.05)3 + $1000 / (1+ 0.05)3
= $80 * 0.952 + $80 * 0.907 + $80 * 0.864 + $1000 * 0.864
= $76.16 + $75.56 + $69.12 + $864
= $1081.84 0r rounded off to $1081.80
Amount need to pay at settlement
Total amount of bond purchases = $10,000,000 at par value
No of Bond Purchased = $10,000,000 / $1000 (Assume Face Value of one bond to be $1000)
= 10,000 bonds to be purchased
Amount Paid for Bond at settlement date = 10,000 Bonds * $1081.80
= $10,818,000
B. Bond’s Macaulay duration and modified duration of Bond
The Macaulay duration of bond s the weighted average term to maturity of the cash flows from a bond. The weight of each cash flow is determined by dividing the present value of the cash flow by the price. Macaulay duration is frequently used by portfolio managers who use an immunization strategy.
The Macaulay duration of bond is calculated as follow by using following formula
= ∑nt=1 [(t×C) / (1+y)t + (n×M) /1+y)n ] / ( Current Bond Price)
Where, t=respective time period
C=periodic coupon payment
y=yield to maturity
n=total no of period or maturity period
M=Maturity value
= [(1 * $80)/(1+0.05)1 + (2 * $80)/(1+0.05)2 + (3 * $80)/(1+0.05)3 + (3 * $1000)/(1+0.05)3] / $1081.80
= [($80* 0.952) + ($160 * 0.907) + ($240 * 0.864) + ($3000 * 0.864)] / $1081.80
= [$76.16 + $145.12 + $207.36 + $2592] / $1081.80
= 2.792 years or rounded off to 2.80 years
Modified duration of bond expresses the measurable change in the value of security in response to change in interest rates. Modified duration follows the concept that interest rates and bond prices move in opposite directions. This formula is used to determine the effect that a 100-basis-point (1 percent) change in interest rates will have on the price of a bond
Modified Duration = Macaulay duration / (1+ytm)
= 2.80 years / (1+.05)
= 2.66 or rounded off to 2.70%
It means that 1% change in interest rate leads to 2.70% change in bond price in opposite direction.
C. Calculation of bond’s dirty price, clean price, and your proceeds from the sale
A dirty price is a bond pricing quote, which refers to the cost of a bond that includes accrued interest based on the coupon rate. Bond price quotes between coupon payment dates reflect the accrued interest up to the day of the quote
A Clean price is a bond pricing quote, which refers to the cost of a bond that Excludes accrued interest based on the coupon rate
Clean Price = Dirty Price - Accrued Interest
Now We have to first calculate dirty price of bond
In question it is given that after 6 months bond have been sale and ytm changes to 4.5% now for calculating price after 6 months we have to first calculate price at the end of first year
B0 = Coupon Amount / (1+ytm)1 + Coupon Amount / (1+ytm)2 + Maturity Value / (1+ytm)2
= $80 / (1+ 0.045)1 + $80 / (1+ 0.045)2 + $1000 / (1+ 0.045)2
= $80 * 0.957 + $80 * 0.916 + $1000 * 0.916
= $76.56 + $73.28 + $916
= $1065.84
Now we have to discount back the price calculated above for 6 months to calculate the bond price after 6 monts
= $1065.84 / (1+0.0225) [Take 6 months doscount rate for 4.5% i.e 2.25%]
= $1042.38 or rounded off to $1042.40
Dirty price = $1042.40
Now for calculating clean price we have to calculate Accrued interest
Accrued Interest = $80 * 6/12
= $40
Therrfore Clean Price = Dirty Price - Accrued Interest
= $1042.40 - $40
= $1002.4
Proceeds From Sale = Current Market price after 6 months * No. Of Bonds Purchased
= $1042.40 * 10,000 Bonds
= $10,424,000
