A protective put locks in a selling price (the strike) for the shares as a safety measure. For instance, let's say you bought 100 shares of Stock XYZ at $100 apiece but value appreciated to $120. However, earnings are around the corner and you're scared the stock may give up some or all of those gains but you also don't want to sell the shares and miss out on potential upside. You could purchase a 110-strike protective put that encompasses the earnings release. That way, if XYZ tumbles back to the century mark after earnings, the protective put allows you to unload your shares at $110-- locking in a 10% profit (minus the cost of the puts, of course). As such, the main goal of a protective put buyer is quite different than that of a “vanilla” put buyer. A protective put buyer is simply using the option as a form of insurance; the trader's ultimate goal is for the shares to move higher and ideally offset the cost of the option, leaving the put to expire worthless. A "vanilla" put buyer, on the other hand, is actively looking for the underlying shares to fall. ## Weighing the Risks While the protective put buyer's goal is to forfeit the initial premium paid for the put-- which represents the maximum risk on the trad-- you don't want to overpay. It's important to select the right strike and options series to accommodate your personal risk tolerance. It is also important to be aware of the risks when trading options ahead of big events such as earnings. When a company has a planned event like earnings on the horizon, options premiums tend to be inflated. As a result, deeper out-of-the-money puts will be more affordable to purchase, but will allow less protection in the end. In addition, the cost of the protective puts depends on time value. A 110-strike put that expires in two weeks will cost less than a put at the same strike expiring in two months, as the latter allows more time for the underlying stock to make a big move. ### 相关股票 - [META.US](https://longbridge.com/zh-CN/quote/META.US.md) - [AMZU.US](https://longbridge.com/zh-CN/quote/AMZU.US.md) - [AMZZ.US](https://longbridge.com/zh-CN/quote/AMZZ.US.md) - [IXN.US](https://longbridge.com/zh-CN/quote/IXN.US.md) - [MSFY.US](https://longbridge.com/zh-CN/quote/MSFY.US.md) - [MSFX.US](https://longbridge.com/zh-CN/quote/MSFX.US.md) - [MSFL.US](https://longbridge.com/zh-CN/quote/MSFL.US.md) - [MSFO.US](https://longbridge.com/zh-CN/quote/MSFO.US.md) - [AMZW.US](https://longbridge.com/zh-CN/quote/AMZW.US.md) - [METW.US](https://longbridge.com/zh-CN/quote/METW.US.md) - [AMZP.US](https://longbridge.com/zh-CN/quote/AMZP.US.md) - [IGV.US](https://longbridge.com/zh-CN/quote/IGV.US.md) - [FBL.US](https://longbridge.com/zh-CN/quote/FBL.US.md) - [MSFU.US](https://longbridge.com/zh-CN/quote/MSFU.US.md) - [METU.US](https://longbridge.com/zh-CN/quote/METU.US.md) - [MSFT.US](https://longbridge.com/zh-CN/quote/MSFT.US.md) - [AMZN.US](https://longbridge.com/zh-CN/quote/AMZN.US.md) ## 相关资讯与研究 - [MetaCTO 激进改革：利用 AI 重塑员工体系 欲打造 “无管理” 大型团队](https://longbridge.com/zh-CN/news/287593106.md) - [AI 繁荣的隐秘真相：数万亿云收入背后的 “循环计账游戏”](https://longbridge.com/zh-CN/news/287536958.md) - [美股不再只靠七巨头：标普 500 其余 493 家公司盈利也开始大增](https://longbridge.com/zh-CN/news/287587768.md) - [Q1 业绩出炉后 Shopify 遭市场重估 巴克莱与花旗双双下调目标价](https://longbridge.com/zh-CN/news/287591209.md) - [财报前瞻 | “AI 颠覆” 阴霾难散！股价腰斩后，赛富时迎来财报大考](https://longbridge.com/zh-CN/news/287508104.md)
