The objectives for the domestic bond portfolio include the ability to fund future liabilities, protect interest income from short-term inflation, and minimize the correlation with the fund’s equity portfolio. The correlation between the fund’s domestic bond portfolio and equity portfolio is currently 0.14. Deveraux plans to reduce the fund’s equity allocation and increase the allocation to the domestic bond portfolio. She reviews two possible investment strategies.
Strategy 1: Purchase AAA rated fixed-coupon corporate bonds with a modified duration of two years and a correlation coefficient with the equity portfolio of –0.15.
Strategy 2: Purchase US government agency floating-coupon bonds with a modified duration of one month and a correlation coefficient with the equity portfolio of –0.10.
Strategy 2 is most likely preferred to Strategy 1 for meeting the objective of:
选项：
A.protecting inflation.
funding future liabilities.
minimizing the correlation of the fund’s domestic bond portfolio and equity portfolio.
解释：
A is correct.
Floating-coupon bonds provide inflation protection for the interest income because the reference rate should adjust for inflation. The purchase of fixed-coupon bonds as outlined in Strategy 1 provides no protection against inflation for either interest or principal. Strategy 1 would instead be superior to Strategy 2 in funding future liabilities (better predictability as to the amount of cash flows) and reducing the correlation between the fund’s domestic bond portfolio and equity portfolio (better diversification).
AAA 固定公司bond于美国政府代理浮动bond， 在考虑fund futuer liabliltiy上不是看质量如何，为什么前者的质量高于后者？？因为前者评级即便高，也是公司债，后者是政府债。
