问题如下图:
选项:
A.
B.
C.
解释:
所以bond equivalent yield就是add-on yield(本质都是Holding period yield)?此外,数量分析里的bank discount yield就是固收里的discount yield?前者以成本为分母,后者以面值为分母。这样理解对吗?
感谢解答。

holding period return是持有期收益率,在本题里面就是:
这3.63%的收益是持有350天的。你可以把他年化。
对于一个半年付息一次的债券,求出来的折现率(discount rate),是每半年现金流的折现率。所以乘以2以后就是Bond equivalent yield,这是年化后的收益率。BEY是将那些不是按年付息的债券每期收益率,调整成年化收益率。
add-on yield基本上多用在货币市场,所以年化时不用复利;
本题是持有350天,要求的是BEY,所以持有期收益率除以350乘以360就是Add-on yield
简单理解:
add-on yield = (FV - PV)/ PV
Discount yield = (FV - PV)/ FV

NO.PZ2016031001000083 为什么要考虑那个settlement的时间呢
为什么不用复利?这部分好混乱!什么时候用单利,什么时候用复利?
