同学,上午好。
1. collar一般都是用的OTM option。但因为题目要求he´s hesitant to sell but wants to protect their value,要保护原股票头寸的价值(价格25.12),所以买入ATM put=25。
2. 第4题是half of his NAIC holdings with bear put spreads and another half with collar option strategy,所以总股数20000,有10000用collar,有10000用bear put。
Collar Option strategy = Buy an ATM put and sell an OTM call = $2.67 – 0.53 = $2.14
Bear put option = Buy an ATM put and sell an OTM put = $2.67 – 0.31 = $2.36
所以成本=2.14*10000+2.36*10000=45,000
