Pierre-Louis Robert just purchased a call option on shares of the Michelin Group. A few days ago he wrote a put option on Michelin shares. The call and put options have the same exercise price, expiration date, and number of shares underlying. Considering both positions, Robert’s exposure to the risk of the stock of the Michelin Group is: A long. B short. C neutral. 这个题不是说call 和 put 同样的价格,为什么不选C

同学你好,
判断一个资产的风险敞口就是判断资产上涨有利还是下跌有利,上涨有利就是long,下跌有利就是short
对于买一个call option,是上涨有利因此它的风险敞口是long
而对于write a put option的意思说卖出一个看跌期权,那么不看好一个看跌期权说明也是看涨。因为也是long。
所以这个组合的风险敞口就是long。
