fixed income mapping中每种方法对应的是哪种风险因子啊? 为什么B选项说是平均到期时间错了,这个平均到期时间是duration mapping吗? 能否给出对应的因子

学员你好。
I. Under the cash flow mapping approach【这个是principal mapping】, only the risk associated with the average maturity of a fixed-income portfolio is mapped.
II. Cash flow mapping is the least【应该是most】 precise method of risk mapping for a fixed-income portfolio.
III. Under the duration mapping approach, the risk of a bond is mapped to a zero-coupon bond of the same duration.【正好映射到久期,这个没问题的】
IV. Using more risk factors generally leads to better risk measurement but also requires more time to be devoted to the modeling process and risk computation.【正确,典型的例子就是CF mapping】
