2. Risk Measurement, Risk Management, Duration - 30 points Dollar duration and convexity are used to characterize and to control the riskiness of fixed income securities. However, several examples were presented in the lectures to exhibit the limitations of these measures. One way we might attempt to improve these measures is by making them more robust to non-uniform shifts in the term structure. For a fixed income security that makes annual payments over four years, P(R1, R2, R3, R4) = X 4 t=1 Kte −t·Rt , 1 where Rt is short for the spot rate R(0, t), we can perform a Taylor expansion to arrive at an expression relating the change in price of the bond to changes in the zero coupon term structure by ∆P ≈ X 4 t=1 ∂P ∂Rt ∆Rt . (1) Consider an 8% coupon bond maturing in four years with a face value of $1000. You are given the following information about the current state of the continuously compounded zero yield curve, and four possible scenarios that might occur instantaneously. Yield Yr. 1 Yield Yr. 2 Yield Yr. 3 Yield Yr. 4 Current 6.25% 7.00% 7.50% 8.00% Scenario 1 7.00% 7.75% 8.25% 8.75% Scenario 2 6.25% 7.50% 8.00% 8.50% Scenario 3 5.00% 6.00% 7.50% 7.00% Scenario 4 7.00% 6.50% 6.25% 6.00% Scenario 5 7.25% 7.25% 7.25% 8.20% For each scenario, compute the following:
3. Risk Management, Duration, and Convexity - 40 points Consider the following three securities: • Security A is a 2-year zero which matures two years from today, and pays $1 at maturity; • Security B is a 3-year zero which matures three years from today, and pays $1 at maturity; • Security C is a 1-year forward contract which matures one year from today, and delivers a 1-year zero (with face value $1) at maturity. My portfolio currently consists of a long position of 5,000 units of security B and a short position (liability) of 3,000 units of security A. Suppose the only securities I can currently trade (buy/sell) are Security A and Security C. The current term structure based on zero coupon bonds (with 1-, 2-, 3-, and 4-year maturity from today) in annualized rates with continuous compounding is: R(0, 1) = 3% R(0, 2) = 5% R(0, 3) = 6% R(0, 4) = 6.5% 2
