Short Put


A Short Put is a financial term refereeing to an investment strategy where an investor sells or writes a put option on a security. The investor is betting that the price of the security will rise or stay the same by the expiry date of the option. If the price falls, the investor is obligated to purchase the security at the strike price, potentially incurring a loss.


The phonetic spelling of “Short Put” is /ʃɔːrt pʊt/.

Key Takeaways


  1. Risks and Rewards: A short put strategy has known and limited potential profit, which is the premium income. However, it has potentially unlimited risk if the price of the underlying security decreases sharply.
  2. Market View: It is commonly used when the investor is neutral to somewhat bullish on the market. The investor sells a put option believing that the price of the underlying asset will remain steady or increase, thus resulting in the put option expiring worthless.
  3. Margin Requirements: Selling put options, or “shorting puts,” requires a margin account with sufficient funds to cover the total obligation. If the option is exercised, the investor will need to purchase the underlying security at the strike price, which could potentially be much higher than the current market price.



A Short Put is a crucial term in business and finance as it refers to an investment strategy that involves the sale of a put option, or the right to sell a specific stock at a predetermined price until a fixed expiry date. The seller, or writer, of the short put, expects the price of the underlying asset to increase or remain stable. Importantly, this strategy allows the seller to generate additional income through the premium received from the option sale. However, there are risks involved – if the stock price falls significantly, the short put writer could face substantial losses as they are obliged to buy the asset at the strike price, which would be higher than the market price. Understanding the concept of Short Put is essential for anyone engaged in options trading as its effective use can optimize investment outcomes.


The purpose of a short put is primarily for investors to generate premium income, especially in neutral or bullish market scenarios. By selling or “writing” a put option, an investor is obligating themselves to buy shares of the underlying asset at a predetermined price, known as the strike price, up until the option’s expiration date. It is an investment method where the investor is expressing a bullish sentiment or a neutral opinion on the underlying asset, as they anticipate that the asset’s price will remain the same or increase over time. Hence, a short put is commonly used when one expects the price of the underlying asset to rise or remain above the strike price during the contract period.Additionally, it’s worth noting that a short put strategy can serve as a way to acquire stocks at a lower price. If the investor has a desire to own a particular stock, they could write a put option for it with the strike price at their desired purchase price. If the stock price falls below the strike price, they will be obligated to purchase it, but essentially at a discount due to the premium they received from selling the put option. However, if the stock price does not fall below the strike price, they will still retain the premium from the sold option, making short puts a flexible strategy for income generation and potential ownership of desired assets.


Sure, here are three examples directly related to the business/finance term, “Short Put”:1. Investment in Stock Market: Suppose an investor named James believes that the stock of Company A, currently trading at $50, will not fall below $45 in the next month. He decides to write a short put option with a strike price of $45 and sells it for a premium of $2. If the stock price stays above $45, James keeps the premium and the option expires worthless. However, if the price falls below $45, James will be obligated to buy the stock at the strike price of $45, despite its lower market price. 2. Insurance Company Policymaking: An insurance company can also make use of short puts. Suppose an insurer believes that the number of claims in the following year will not exceed a certain amount and writes a short put option equivalent to the expected claims’ value. If the claims are below the strike price, the insurer keeps the premium collected. But if the claims exceed the strike price, the insurer will have to pay out up to the claims’ total value.3. Commodity Trading: Let’s take an example of a farmer who expects the price of corn will not decrease significantly in the coming months. The farmer may decide to write a short put option on corn contracts. If the market price stays above the strike price, the farmer gets to keep the premium. However, if the price of corn drops, the farmer will have to buy corn at the agreed strike price, which is higher than the market price.
