The correct answer is A

 

percentage price change = [–duration ′ Dy ′  [(1/2)+100]  ′ convexity ′ Dy2 ′ 100]

-7.86(0.002)100 + (0.5)76.93(0.002)²(100) = -1.5566

Baran

 

The correct answer is B

N = 20; I/Y = 4.45/2; PMT = 500/2; FV = 10,000; CPT PV = 10,440.05 = V–

N = 20; I/Y = 4.55/2; PMT = 500/2; FV = 10,000; CPT PV = 10,358.33 = V+

N = 20; I/Y = 4.50/2; PMT = 500/2; FV = 10,000; CPT PV = 10,399.09 = V0

The effective convexity of the bond is closest to:

4、A 10-year maturity Treasury bond has a par value of $10,000 and a 5 percent coupon. The yield on the bond is 4.5 percent. Assume that the yield can fall to 4.45 percent or rise to 4.55 percent.

The effective duration for the bond is closest to:

A) 8.07.  

B) 7.86. 

C) 7.24.  

D) 7.61.

Baran

 

The correct answer is C

 

I/Y = 9.00; FV = 100; N = 10; PMT = 0.11 x 100 = 11; PV = V0 = 112.84

I/Y = 8.50; FV = 100; N = 10; PMT = 0.11 x 100 = 11; PV = V- = 116.40

I/Y = 9.50; FV = 100; N = 10; PMT = 0.11 x 100 = 11; PV = V+ = 109.42

D = effective duration     =  [(V- - V+) / (2V0(Δy))]

                                   = (116.40 – 109.42)/(2x112.84x0.005)

                                   = 6.19

3、A major problem with the use of duration in interest rate risk management is that it assumes:

A) differential sensitivity of assets and liabilities to changes in interest rates.  

B) a nonlinear relationship between prices and rates.

C) only a single change in interest rates over the planning horizon.  

D) an inverse relationship between prices and rates.

Baran

 

The correct answer is C

 

Duration assumes only a single and parallel shift in interest rates over the interest rate management planning horizon.

Baran

 

The correct answer is A

 

Duration measures the sensitivity of an instrument’s market value to changes in interest rates. Note that maturity, yield, and coupon, are all features of bonds that tie into determining duration.

2、A 10-year, 11 percent annual coupon bond with $100 par value currently yields 9 percent. What is the duration of the bond given a 50 basis point change in yield?

A) 4.80 years.  

B) 6.95 years. 

C) 6.19 years.  

D) 7.27 years.

AIM 4: Define and compute effective duration, and interpret the effective duration of a fixed income security, given a change in yield and the resulting change in price.

1、The most commonly used measure of interest-rate risk is:

A) duration.  

B) maturity. 

C) yield.  

D) coupon.
