Q2 Bond Return and Convexity

Consider a self-financed convexity trade.

Three zero coupon bonds: i. 2Y zero at 1.60%; ii. 10Y zero at 1.85%; iii. 30Y zero at 2.30%

a. Calculate duration and convexity for all three bonds.

b. If you want to combine 2Y and 30Y zero to match the $100M bullet in 10Y zero for dollar duration, what are the percentage weights in 2Y and 30Y respectively? (note: combined value in 2Y and 30Y is also $100M, i.e. weights sum up to 100%)

c. The combination of 2Y and 30Y is a barbell. 10Y only position is a bullet. What are the daily interest accruals of $100M portfolio in long barbell portfolio, and $100M in long bullet, respectively (4 points)?

d. What is the DOLLAR convexity of a dollar duration neutral that is LONG barbell and SHORT bullet (LONG $100M of barbell and SHORT $100M of bullet)?

e. What is the total PnL for a 10 bps upward parallel movement of yield curve?

f. What is the total PnL for a 2 bps downward parallel movement of yield curve?

g. What is the breakeven level of single day parallel yield change for the long-short portfolio? (hint: breakeven level is achieved when convexity profit is offset by daily interest cost)

Bond A and Bond B are zero-coupon bonds issued by the same government. Bond A is due to mature in exactly t years from today, and Bond B is due to maturity in exactly T years from today (t<T). If the zero rate curve (for the government bonds) is downward sloping, which of the following statements is correct? A. Since there two bonds are issued by the same government, the yield of Bond A is the same as the yield...

Question 4. A 12.75-year maturity zero-coupon bond has convexity of 150.3 and modified duration of 11.81 years. A 30-year maturity 6% coupon bond with annual coupon payments has nearly identical modified duration of 11.79 years, but considerably higher convexity of 231.2. Suppose the yield to maturity on both bonds increases by 1%. What percentage change in price of the bonds as predicated by the duration plus convexity model? (6) Repeat part (a), but this time assume that the yield to...

An investor is considering the purchase of zero-coupon U.S. Treasury bonds. A 30-year zero-coupon bond yielding 8% can be purchased today for $9.94. At the end of 30 years, the owner of the bond will receive $100. The yield of the bond is related to its price by the following equation: Here, P is the price of the bond, y is the yield of the bond, and t is the maturity of the bond measured in years. Evaluating this equation...

Consider two bonds: 1) a zero-coupon bond having a face value F and maturity 1 year; 2) a coupon bond with face value F, coupons C = 15 paid annually and maturity 3 years. Assume that the continuously compounded interest rate is 10%. a) If F = 100, find at the end of which year the price of the second bond will be for the first time below 110? b) If the price of the second bond is equal to...
