empirical duration的两个问题:1 empirical duration小于effective duration:Interest rate is negatively related with 信用利差,当interest rate下降,spread 上升,波动率更小。这上面我是明白的,【但我还是不懂为什么可以得出债券的empirical duration更小的结论】 2.empirical duration小于0: 因为当债券价格下跌时,垃圾债会被大量卖出,所以垃圾债的empirical duration为负。这种解释对吗?以上都麻烦老师先看下我的问题再回答,谢谢哈。
已回答老师您好,关于这段话的理解,违约风险removed该如何理解呢?其公式是否应为:Long-term~Asset~Return=policy~neutral~rate+default~premium,违约风险removed之后,neutral~rate实际为负?
