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. ### 相關股票 - [META.US](https://longbridge.com/zh-HK/quote/META.US.md) - [AMZU.US](https://longbridge.com/zh-HK/quote/AMZU.US.md) - [AMZZ.US](https://longbridge.com/zh-HK/quote/AMZZ.US.md) - [IXN.US](https://longbridge.com/zh-HK/quote/IXN.US.md) - [MSFY.US](https://longbridge.com/zh-HK/quote/MSFY.US.md) - [MSFX.US](https://longbridge.com/zh-HK/quote/MSFX.US.md) - [MSFL.US](https://longbridge.com/zh-HK/quote/MSFL.US.md) - [MSFO.US](https://longbridge.com/zh-HK/quote/MSFO.US.md) - [AMZW.US](https://longbridge.com/zh-HK/quote/AMZW.US.md) - [METW.US](https://longbridge.com/zh-HK/quote/METW.US.md) - [AMZP.US](https://longbridge.com/zh-HK/quote/AMZP.US.md) - [IGV.US](https://longbridge.com/zh-HK/quote/IGV.US.md) - [FBL.US](https://longbridge.com/zh-HK/quote/FBL.US.md) - [MSFU.US](https://longbridge.com/zh-HK/quote/MSFU.US.md) - [METU.US](https://longbridge.com/zh-HK/quote/METU.US.md) - [MSFT.US](https://longbridge.com/zh-HK/quote/MSFT.US.md) - [AMZN.US](https://longbridge.com/zh-HK/quote/AMZN.US.md) ## 相關資訊與研究 - [外流音檔曝祖克柏為蒐集員工鍵鼠軌跡辯護不會用於 KPI，但當天大裁員 8 千人](https://longbridge.com/zh-HK/news/287485862.md) - [Google 發表 Android XR 智慧眼鏡 Alphabet AI 硬體戰線正面迎戰 Meta、蘋果](https://longbridge.com/zh-HK/news/287483646.md) - [良維股東會／衝刺輝達 Vera Rubin 下半年爆發](https://longbridge.com/zh-HK/news/287516649.md) - [輝達軟體架構主管：AI 也會「物以類聚」！同模型寫履歷更易通過篩選系統](https://longbridge.com/zh-HK/news/287473622.md) - [Meta Platforms, Inc. $META 股票被路德會 Thrivent Financial 出售](https://longbridge.com/zh-HK/news/287524149.md)
