问题如下:

1.Based on Exhibit 1 and assuming annual compounding, the arbitrage profit on the bond futures contract is closest to:

选项:

A.

0.4158

B.

0.5356

C.

0.6195

解释:

B is correct.

The no-arbitrage futures price is equal to the following:

F0(T) = FV0,T(T)[B0(T + Y) + Al0  PVCI0,T]

F0(T) = (1 + 0.003)0.25(112.00 + 0.08 - 0)

F0(T) = (1 + 0.003)0.25 (112.08) = 112.1640

The adjusted price of the futures contract is equal to the conversion factor multiplied by the quoted futures price:

F0(T)=CF(T)QF0(T)

F0(T) = (0.90)(125) = 112.50

Adding the accrued interest of 0.20 in three months (futures contract expiration) to the adjusted price of the futures contract gives a total price of 112.70.

This difference means that the futures contract is overpriced by 112.70 - 112.1640 = 0.5360. The available arbitrage profit is the present value of this difference: 0.5360/(1.003)0.25 = 0.5356.

老师,什么时候折现用单利,什么时候折现用复利。已经搞混了。。。这题用单利答案是一样的

嗨,爱思考的PZer你好:


同学你好,我们目前学到的产品以LIBOR为标的的时候,如果题目中没有明确说明,都是用单利的,如interest swap,FRA;这道题目是债券期货合约的定价,这里将未来现金流使用无风险利率向前折现,是要用复利来计算的
