问题如下：
Cécile
is a junior analyst for an international wealth management firm. Her
supervisor, Margit, asks Cécile to evaluate three fixed-income funds as part of
the firm’s global fixed-income offerings. Selected financial data for the funds
Aschel, Permot, and Rosaiso are presented in Exhibit 1. In Cécile’s
initial review, she assumes that there is no reinvestment income and that the
yield curve remains unchanged.
Based on Exhibit 1, which fund provides the highest level of protection against inflation for coupon payments?
选项：
A.Aschel
Permot
Rosaiso
解释：
Correct Answer: B
B is correct. Permot has the highest percentage of floating-coupon bonds and inflation-linked bonds. Bonds with floating coupons protect interest income from inflation because the reference rate should adjust for inflation. Inflation-linked bonds protect against inflation by paying a return that is directly linked to an index of consumer prices and adjusting the principal for inflation. Inflation-linked bonds protect both coupon and principal payments against inflation.
The level of inflation protection for coupons equals the percentage of the portfolio in floating-coupon bonds plus the percentage of the portfolio in inflation-linked bonds:
Aschel = 2% + 3% = 5%.
Permot = 34% + 28% = 62%.
Rosaiso = 17% + 21% = 38%.
Thus, Permot has the highest level of inflation protection, with 62% of its portfolio in floating-coupon and inflation-linked bonds.
老师请问，这里仅是问inflation protection for coupon为何加上inflation-linked? 如果是两者相加，难道问法不应该是highest inflation protection for coupon and principal?
