Question

Quizplus · Accepted Answer

To immunize a portfolio, the duration of the portfolio must match the investment horizon. Given the investment horizon is two years, the proportion of investment in each bond should be calculated in such a way that the overall duration of the portfolio equals two years. Without the specific calculations of duration for each bond, the correct answer cannot be determined mathematically here. However, the question seems to imply that option A is the correct allocation to achieve immunization, assuming the calculations behind the scenes have been done correctly to match the portfolio's duration with the investment horizon.
