Hedge adjustment factor

Mapping for fixed-income securities

?Principal mapping. This method includes only the risk of repayment of principal amounts.

?Duration mapping. With this method, the risk of the bond is mapped to a zero-coupon bond of the same duration.

?Cash flow mapping. With this method, the risk of the bond is decomposed into the risk of each of the bond’s cash flows.

常考點：

1. 現(xiàn)金流映射會比其他兩種方法產(chǎn)生更加精確的結果。

2. 本金映射只考慮本金到期時間的相關風險。

3. 使用的風險因子越多通常結果越準確，但也會使模型更復雜，所需要的計算更多。

例題：

In fixed income portfolio mapping, when the risk factors have been selected, which of the following mapping approaches requires that one risk factor be chosen that corresponds to portfolio duration?

A. Principal mapping

B. Duration mapping

C. Present value mapping

D. Cash flow mapping

【正確答案】B

【答案解析】With principal mapping, one risk factor is chosen that corresponds to the average portfolio maturity. With duration mapping, one risk factor is chosen that corresponds to the portfolio duration. With cash flow mapping, the portfolio cash flows are grouped into maturity buckets. Present value mapping is not a method of VaR mapping for fixed income portfolios.
