NO.PZ2019010402000058

问题如下:

Eden wants to purchase a 15-year Treasury note futures contract. The underlying 3%, semi-annual Treasury note has a dirty price of 105. It has been 60 days since the last coupon payment. The futures contract expires in 90 days. The current annualized three-month risk-free rate is 1.60%. The conversion factor is 0.80. the equilibrium quoted futures contract price based on the carry arbitrage model is:

选项:

A.

103.1665

B.

104.1675

C.

130.2094

解释:

C is correct。

画图法解析如下:


您好,accured interest的计算应该是3/2*60/180, 题目中写的是距离上一个付息日已经过了了60天,所以,分子应该是60天才对,为啥题目写的是150天/180天,没有明白为什么是150天做分子

嗨,爱思考的PZer你好:


自上次发息日已经过了90天,但是settlement date是future contract结束的时间,所以是60+90天。
