老师这里是怎么判断呢?我看了解析,没懂。Robert’s exposure to the risk of the stock of the Michelin Group is long. The exposure as a result of the long call position is long. The exposure as a result of the short put position is also long. Therefore, the combined exposure is long. 这个解析就是这样说的,他只是说买了call option和put option,怎么解析又来了一个short put option,不能是 long put吗?还有就是这道题的逻辑是什么呢?该怎样去读出他每个操作的exposure呢?

同学你好。题目说的是purchase call option是买看涨期权,wrote put option是卖看跌期权。
long call option,当你行权后,你会以行权价格买入标的资产,这时你对标的资产的风险敞口是long;
short put option,当对方行权后,对方会以行权价格将标的资产卖给你(你买入标的资产),这时你将拥有标的资产,对标的资产的风敞口是long;
两个对标的资产的风险敞口都是long,那综合起来就是long。
