问题如下：
Based on the information in Exhibit 2, the total option premium to hedge Raghav’s NAIC holdings is closest to:
选项：
A.$42,800. B.$45,000. C.$47,200.解释：
Collar Option strategy = Buy an ATM put and sell an OTM call = $2.67 – 0.53 =$2.14
Cost per collar option contract = $2.14 × 100 = $214
Cost to hedge half of NAIC holdings = $214 × (10,000/100) = $21,400
Bear put option = Buy an ATM put and sell an OTM put = $2.67 – 0.31 = $2.36
Cost per bear put option contract = $2.36 × 100 = $236
Cost to hedge half of NAIC holdings = $236 × (10,000/100) = $23,600
Total premium paid = $45,000
The total cost to hedge 20,000 shares of NAIC is $45,000.
对于payoff来说的话如果bear put加上hold的stock难道不是没有办法完全cap住downside? 价格低于20的时候拥有的stock在亏钱，short的put在亏钱，long的put在赚钱但是没有办法cover两个亏钱的吧？谢谢老师！
