问题如下:
The full spot price of the three-year Treasury note is:
选项:
A.101.00.
101.25.
101.50.
解释:
B is correct.
The full spot price of the three-year Treasury note is calculated as
S0 = Quoted bond price + Accrued interest = B0 + AI0
Accrued interest ( AI )= Accrural period × Periodic coupon amount = (NAD/NTD)× (C/n)
AI = (60/180) × (0.015*100/2) = 0.25.
S0 = 101 + 0.25 = 101.25
中文解析:
本题考察的是计算债券的full price S0 。
S0 = B0 + AI0
B0 为clean price;
AI0 为过去的60天发生的coupon,计算公式为AI0 = NAD/NTD)× (C/n)= (60/180) × (0.015*100/2) = 0.25.
之前做了PZ题库另一道题
题干一样,但是计算AI0的时候没有考虑之前60天的coupon,AI0=0, 然后这道题目A0却考虑了60天前的coupon,请问到底是哪个答案给错了。
同理,如果要计算AIT的话,因为120天后还有一次coupon,是否要同时考虑60天前和120天后的coupon,这样60天前的coupon同时在AI0和AIT都要被考虑,计算2次吗? 麻烦写下AIT的计算过程。
