同学,下午好。协会mock的解析不对,因为long straddle策略应该long执行价格相同的期权,put和call都应选择Exercise Price=39.5对应的期权。
A straddle strategy is implemented by buying closer to ATM puts and ATM calls.
Cost of closest to ATM put option (i.e., $39.50 strike) is $2.22.
Cost of ATM call option (i.e., $39.50 strike) is $2.40.
Cost of each straddle option = $2.22 + $2.40 = $4.62
Number of option contracts required to hedge Reddy’s CFT position = 50,000/100 = 500 option contract
Overall cost to implement collar strategy = $4.62 x 500 = $2,310
如果题目中没有 正好ATM的option,那就选行权价距离当前股价最接近的那个。
