为什么VND==国债价格,而不是一个没有违约风险的公司债?是因为YTM三大假设吗?
吴昊_品职助教 · 2019年03月27日
首先,对于VND投资者要求的回报率就是无风险利率,国债的要求回报率是rf。其次,VND假设没有违约,此时公司债的value相当于期限相同,coupon rate相同的国债的value,因为国债才没有违约风险。所以VND就是国债的价格。和YTM三大假设没有关系。

请问下YTM的三大假设是什么
吴昊_品职助教 · 2020年03月14日
投资债券要获得YTM的收益率满足三个假设条件(1)债券持有至到期(2)不考虑违约风险(3)中间现金流以YTM进行再投资。

老师说VND就是国债的价格,可是在浮动利率债券中,VND和国债的折现率都是rf,但是VND有quoted margin,国债的quoted margin=0,二者夫人价格怎么相等呢?
吴昊_品职助教 · 2020年03月21日
如果是浮动利率债券,我们需要用到二叉树来求VND,而不再是简单的用rf来折现了。不要混淆。
