3. Suppose we look in the newspaper and find the following rates: the rate on 1-year securities is 4.65%, on a similar 2-year security 6.30%, and a 3-year security 6.67%.

4. Consider the following bonds:
a. What is the duration of a five-year bond with a 6.5 percent semiannual coupon if the yield to maturity (ytm) is 7.00%?
b. What is the duration of a 20-year zero coupon bond with a yield to maturity of 7.65%

c. You expect a sudden, but widely unanticipated, decrease in the market rates of interest due to a change in position by the Federal Reserve.

Please try and complete practice problems leading to next week's exam. Assume all bonds have a face value of \$1,000.00, unless otherwise informed

1. You buy an investment today for \$9,825. You sell the investment in 90 days for \$10,000.
a.  What is the nominal annual return on this investment?

Investment= \$9,825
Selling value= \$10,000
Number of days= 90 days
Number of days in a year= 365 days

Return over a period of 90 days= 1.78% =(10000 / 9825) -1
Nominal annual rate of return= 7.22% =1.78% x ( 365 / 90)

b.  What is the effective annual rate on this investment?

Effective annual rate on this investment= 7.42% ={(1+ 1.78%) ^ ( 365 / 90)} - 1

2.  A 10 year semi-annual payment corporate coupon bond has a coupon rate of 11% and a required return of 10%. The bond's market price is

To calculate the price of the bond we need to calculate / read from tables the values of
PVIF= Present Value Interest Factor
PVIFA= Present Value Interest Factor for an Annuity
Price of bond= PVIF * Redemption value + PVIFA * interest payment per period

PVIFA( n, r%)= =[1-1/(1+r%)^n]/r%
PVIF( n, r%)= =1/(1+r%)^n

Price of bond
Coupon rate= 11.000%
Face value= \$1,000
Interest payment per year= \$110.00 =11.% x 1000

Frequency= S Semi Annual

No of years to maturity= 15
No of Periods=n= 30 =2x15

Discount rate annually= 10.00% (YTM)
Discount rate per period=r= 5.00% =10.%/2 Semi Annual

Price of bond=PVIFA X Interest Payment per period +PVIF X Redemption value

Interest payment per period= \$55.00 =110/2
Redemption value= \$1,000 =Face Value

PVIF (30 periods, 5.% rate)= 0.231377
PVIFA (30 periods, 5.% rate)= 15.372451

PVIFA X Interest Payment= \$845.48 =15.372451*55
PVIF X Redemption value= \$231.38 =0.231377*1000
Total= \$1,076.86 =Price of bond

Answer: Price of bond= \$1,076.86

3.  Suppose we look in the newspaper and find the following rates: the rate on 1-year securities is 4.65%, on a similar 2-year security 6.30%, and a 3-year security 6.67%. If the unbiased ...
