问题如下：

An investor sells a June 2008 call of ABC Limited with a strike price of USD 45 for USD 3 and buys a June 2008 call of ABC Limited with a strike price of USD 40 for USD 5. What is the name of this strategy and the maximum profit and loss the investor could incur?

选项：

A.

Bear spread, maximum loss USD 2, maximum profit USD 3

B.

Bull spread, maximum loss unlimited, maximum profit USD 3

C.

Bear spread, maximum loss USD 2, maximum profit unlimited

D.

Bull spread, maximum loss USD 2, maximum profit USD 3

解释：

ANSWER: D

This position is graphed in Figure below. It benefits from an increase in the price between 40 and 45, so is a bull spread. The worst loss occurs below K1K_1 = 40, when none of the options is exercised and the net lost premium is 5−3=25-3=2. The maximum profit occurs above K2=45K_2=45, when the two options are exercised, for a net profit of $5 minus the lost premium, which gives $3.
