2024-07-03 23:30老師,mock,這個(gè)3題。為啥collar要atm的put,otm的call? 還有就是這個(gè)3題思路不理解。
第第4題是求total premium to hedge Naic holding。也不懂。

同學(xué),上午好。
1. collar一般都是用的OTM option。但因?yàn)轭}目要求he's hesitant to sell but wants to protect their value,要保護(hù)原股票頭寸的價(jià)值(價(jià)格25.12),所以買入ATM put=25。
2. 第4題是half of his NAIC holdings with bear put spreads and another half with collar option strategy,所以總股數(shù)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
