Empirical duration is likely the best measure of the impact of yield changes on portfolio value, especially under stressed market conditions, for a portfolio consisting of:
A 100% sovereign bonds of several AAA rated euro area issuers.
B 100% covered bonds of several AAA rated euro area corporate issuers.
C 25% AAA rated sovereign bonds, 25% AAA rated corporate bonds, and 50% high-yield corporate bonds, all from various euro area sovereign and corporate issuers.

這是新增知識點,麥考利久期和有效久期等通過公式得出的叫做分析久期analytical duration;而通過債券的歷史數據計算得出的叫實證久期empirical duration,更適用于估計高風險高收益債券的久期,特別是在經濟不好時,高收益債券的實證久期會小于分析久期,主要是由于基準利率和利差呈負相關關系,記住結論即可。
