Reading 32: Hedging Mortgage Securities to Capture Relati

par, instrument, mortgage, expected, security

LOS e: Contrast a two-bond hedge that takes account of yield curve level and twist changes with a duration hedge.

Q1. A given mortgage security is trading at par. The expected average price change from a projected change in a given market yield is 1 for the mortgage security and 0.4 and 2.0 for hedging instrument one and two respectively. The expected average price change from a projected twist in the yield curve is 0.4 for the mortgage security and 0.3 and 0.5 for hedging instrument one and two respectively. What positions in hedging instruments one and two should a manager take to hedge the price of the mortgage security from the projected market changes? For every dollar of face value of the mortgage security:

A) buy $2.5 of hedging instrument one and $0.5 of hedging instrument two.

B) sell $0.75 of hedging instrument one and $0.35 of hedging instrument two.

C) sell $2.5 of hedging instrument one and $0.5 of hedging instrument two.

Q2. When a one-bond hedge is inadequate for hedging a mortgage security and a two-bond hedge is required, all of the following are necessary assumptions for using a two-bond hedge EXCEPT:

A) reliable assumptions in the Monte Carlo simulations of interest rates.

B) the security’s price change given a small change in yield.

C) the yield curve will shift in a parallel fashion.

Q3. In contrast to a one-bond hedge, a two bond hedge relies:

A) more on duration measures and less on simulations of interest rates.

B) more on duration measures and more on simulations of interest rates.

C) less on duration measures and more on simulations of interest rates.

Q4. In contrast to hedging a Treasury security with a one-bond hedge, when hedging mortgage securities, a two-bond hedge:

A) is more appropriate and requires more assumptions.

B) is less appropriate and requires fewer assumptions.

C) is more appropriate and requires fewer assumptions.
