同学,上午好。
Statement 1: Immunization is a process of structuring and managing a fixed income portfolio to minimize the variance in the realized rate of return over a known investment horizon.
Statement 2: Single liability immunization is achieved by matching the modified duration of the bond portfolio to the horizon date.
其中,statement 1出自书上原话。可以把the variance in the realized rate of return理解为interest rate risk(用标准或方差来表示风险),interest rate risk主要有price risk和reinvestment risk。immunization就是使price risk和reinvestment risk相互抵消。
站在考试的角度,用麦考利久期匹配是上课时一直有强调的,所以,statement 2看仔细点就能发现是错的,然后通过排除法就能找到正确答案。
