Q2 Bond Return and Convexity. Consider a self-financed convexity trade.

Three zero couple bonds:

i. 2Y zero at 1.00%; ii. 10Y zero at 2.50%; iii. 30Y zero at 3.50%.

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