You WILL LOSE your premium from time to time. Hedge is a "probability" game. You have to accept the fact that sometimes you will lose your hedge position.
However, hedge, unlike pure option plays, has a huge R/R in your favor. Even if you are correct 50% of the time, you will still be able to generate higher return than if you do not hedge at all. It is a simple math.
英伟达(NVDA)下周就要发布三季报了。现在股价在 $130 左右,财报如果一切顺利,可能继续冲高,但要是“爆雷”,直接砸10%、15%也是常有的事。
问题是:
如果你持有 10,000 股,市值 130 万美元,你敢裸奔过财报吗?
能不能花点钱对冲一下风险?
Put买了真的有用吗?会不会方向都对了还是亏钱?
今天我用实战例子来拆解一下
一、最简单直接的方式:买 Put
比如你买 100 张 $130 的 Put(每张对应100股),当前价格 $3,成本$30,000
如果 NVDA 财报爆雷,跌到 $115
那这张 Put 的价值就是 $130 - $115 = $15
你成本是 $3,净赚 $12
100 张合约 × $12 × 100 股 = $120,000 收益
如果只是小跌,比如跌到 $123.5,Put大概值 $6.5,你赚 $3.5,差不多赚 $35,000
跌得越多,赚得越猛
跌到 $110,你能赚超过 $160,000
但要注意:财报如果不雷,甚至涨一点,你的 Put 会因为时间价值衰减+IV崩溃直接归零。就是所谓的“方向没错,还是亏钱”。
二、嫌 Put 太贵?你有别的选择
1)Collar:买一个 Put 的同时卖一个 Call,比如
买 $125 Put,卖 $145 Call,收回来的权利金可以抵掉买Put的成本
几乎不用花钱,还能防止下跌。
但涨太多你赚不到了(比如涨到 $150,你只拿到 $145)
2)Put Spread:比如买 $130 Put,卖 $115 Put
花费可能只要 $2
你防止中度暴跌($130 → $115),再往下你自己承担
比直接买Put省钱不少,但也是“有限保护”
3)Covered Call:如果你根本不想花钱保护,
那就卖 $145 的 Call,拿回一点权利金,比如每张$3,也就是 $30,000 进账
算是跌的时候给你一点缓冲,涨太多你股票被call走而已

反指我还没找到任何R/R高ratio的策略
卖145 call 或put spread: 买130 put, 卖115 put
