同學(xué),上午好。題目選A。
原文描述:First, the new single-period immunization strategy should require as a minimum condition that the duration of the bond portfolio equal the investment horizon. In addition, if the bond portfolio has a yield to maturity equal to the target yield and a maturity equal to the investment horizon, then the target value will be achieved".
duration of the bond portfolio equal the investment horizon這句是正確的。
a yield to maturity equal to the target yield and a maturity equal to the investment horizon,這句是錯(cuò)的。
所以答案選A。duration的描述是正確的,但債券YTM描述是錯(cuò)的。
對(duì)于單負(fù)債,要滿足的是
1. 資產(chǎn)的初始市場(chǎng)價(jià)值要等于或超過(guò)負(fù)債的現(xiàn)值(PVA ≥ PVL)
2. 組合的麥考利久期要匹配負(fù)債的到期日(DA = DL)
3. 最小化資產(chǎn)的convexity
然后
