问题如下:

To perform Analysis 1, McKee should use historical bond:

选项:

A.

prices.

B.

yields.

C.

durations.

解释:

B is correct. In order to simulate the impact of the latest financial crisis on the current bond portfolio holdings, McKee’s valuation model for bonds should use the historical yields of bonds with similar maturity. Historical yields drive the
pricing of bonds more than the price history or the current duration. Historical prices for the fixed-income positions currently held in the portfolio may not exist, and even when historical prices do exist, they may not be relevant to the current characteristics (e.g., maturity) of the instrument. Even if the same bonds existed at the time of the latest financial crisis, their durations would change because of the passage of time.

A is incorrect because using a bond’s past price history would mischaracterize the risk of the current portfolio holdings. For this reason, the historical yields are more important in explaining the risks. Historical prices for the fixedincome positions currently held in the portfolio may not exist, and even when historical prices do exist, they may not be relevant to the current characteristics (e.g., maturity) of the instrument.

C is incorrect because historical bond durations would not capture the current characteristics of the bonds in the portfolio. Duration is a sensitivity measure and is the weighted-average time to maturity of a bond. Even if the same bonds existed at the time of the latest financial crisis, their remaining time to maturity and durations would change because of the passage of time.

老师请问这题其实是想说明利率yield在金融危机下不会受到很大冲击?而price和duration却会受到影响?

同学你好,本题考查R45-Historical Scenarios的理解。

本题的重点是想考查一个原版书的结论:Historical scenarios are scenarios that measure the hypothetical portfolio return that
would result from a repeat of a particular period of financial market history.
我们对固定收益证券进行历史模拟的时候,通常使用情景模型里利用收益率作为一个指标进行考查。

因为固定收益证券的价格有时在考查的历史时期还未被发行;用久期这个概念在金融危机时很不稳定,所以也不用。

本题考查的结论不是考纲重点,建议同学直接记忆结论。
