2.Consider a portfolio of 3 bond A and 2 Annuity B, the yield rate is i=5% for A and B. Bond A: F= = $1000, 4-year with annual coupon at 4%, Annuity B: A one-year deferred annuity-immediate with 3 level payments 50. (1) What is the PV of this portfolio? (2) Find the Macaulay Duration Da and Dg (3) Find the Modified Duration MDA and MDE (4) Find the Modified Duration for the portfolio. (5) Use modified approximation to estimate the change in PV when both bond yield rate rise by 0.2%
