Knock-Out Option


A knock-out option is a type of exotic option, which is similar to a standard option but with a built-in feature called ‘knock-out barrier.’ When the underlying asset’s price reaches the specified knock-out barrier level, the option is automatically terminated and rendered worthless. This feature provides both the buyer and the writer of the option with a cap on their potential gains or losses.


The phonetic pronunciation of the keyword “Knock-Out Option” is:- Knock-Out: /ˈnɒk ˈaʊt/- Option: /ˈɒpʃən/In the International Phonetic Alphabet, it would be written as:- Knock-Out: /ˈnɒk ˈaʊt/- Option: /ˈɒpʃən/

Key Takeaways

  1. A Knock-Out Option is a type of option contract that becomes inactive or worthless if the underlying asset reaches a predetermined price level, called the ‘knock-out barrier.’ These options are used by investors to protect themselves from extreme price movements or to reduce the cost of the option premium.
  2. There are two types of Knock-Out Options: Up-and-out and Down-and-out. Up-and-out options become inactive when the underlying asset price rises above the knock-out barrier, while Down-and-out options are deactivated if the underlying asset price falls below the barrier. Both types can be applied to call and put options.
  3. Knock-Out Options offer benefits such as lower premiums compared to regular options (due to the additional barrier) and the ability for traders to express a view on specific price ranges. However, they also carry unique risks, such as potentially becoming worthless if the knock-out barrier is breached, even if the option would have otherwise been profitable at expiration.


The Knock-Out Option is an important business/finance term as it provides a unique risk management tool for investors and traders, who seek to create cost-efficient and tailored option strategies. These options have built-in barriers that “knock-out” or terminate the option if the underlying asset’s price reaches a predetermined level, either higher or lower than the initial price, thus placing a cap on potential profits and losses. As a result, knock-out options tend to be cheaper than regular options due to the restricted profit potential. Additionally, they are attractive for their flexibility, encouraging an efficient use of capital, enabling sophisticated hedging mechanisms, and helping to minimize counterparty credit risk. Ultimately, knock-out options create a valuable strategic option for both inexperienced and advanced investors to navigate volatile markets and optimize their portfolios.


Knock-out options play a significant role in the world of finance and business, providing market participants with a versatile risk management tool. Essentially, a knock-out option is a type of exotic option that ceases to exist when the underlying asset reaches a predetermined barrier level. This mechanism offers a cost-efficient method for investors and traders to hedge their exposures, capture opportunities, or lock in profits during periods of significant market volatility. For instance, imagine an investor who anticipates that a stock will appreciate moderately over a period but has concerns about the possibility of a sharp price decline. In this scenario, the investor could purchase a knock-out put option with a barrier that represents the level at which they are no longer comfortable holding that particular stock. If the stock’s price falls and reaches the barrier level, the knock-out put option would be triggered, allowing the investor to exit the position and minimize losses. On the other hand, if the stock appreciates as anticipated, the knock-out option eventually becomes worthless; however, the investor can still benefit from the stock’s price increase. In this way, knock-out options cater to various strategic approaches while enabling market participants to mitigate the risks associated with unpredictable market fluctuations.


A knock-out option is a type of barrier option that ceases to exist if the underlying asset reaches a specified price barrier before expiration. This type of option is popular among investors as it often provides lower premiums due to the added constraints. 1. Foreign Exchange (Forex) Trading: In the foreign exchange market, an investor may purchase a knock-out option for trading a currency pair, such as the EUR/USD. If they buy a call option with a knock-out barrier, they are betting that the EUR will appreciate against the USD. If the EUR/USD reaches the specified barrier before the option’s expiration, the option will cease to exist, and the investor will not earn any payout. 2. Commodity Options: In the commodities market, a knock-out option can be used to hedge risks or speculate on future price movements. For instance, a crude oil trader might purchase a put knock-out option on oil futures. The trader would profit if the price of crude oil drops without hitting the specified knock-out barrier within the option’s lifespan. However, if the price reaches the barrier, the option becomes worthless. 3. Stock Options: In the context of stock options, an investor could purchase a knock-out option on a specific company’s shares to protect their investment from sudden market movements. For example, an investor might buy a call knock-out option on XYZ company’s shares at a strike price of $100 with a knock-out barrier at $90. This allows them to potentially profit from the appreciation of XYZ’s shares without reaching the $90 barrier. If the share price drops to or below the barrier, the knock-out option becomes void; thus, limiting the potential downside risk.

Frequently Asked Questions(FAQ)

What is a Knock-Out Option?
A Knock-Out Option is a type of option contract that automatically expires or becomes worthless if the underlying asset reaches a predetermined price level, known as the “knock-out barrier,” before the option’s expiration date. It is mainly used by traders to limit the risk associated with traditional options.
How does a Knock-Out Option work?
If the underlying asset’s price reaches the specified knock-out barrier at any point before the option’s expiration date, the option is immediately rendered worthless, regardless of its previous value. If the asset’s price does not reach the barrier, the option operates like a standard option and can be exercised according to its terms.
What are the benefits of using Knock-Out Options?
Knock-Out Options are popular among traders because of their risk management potential. By establishing a knock-out barrier, traders can limit their exposure to substantial market swings and reduce the impact of potential losses. Additionally, Knock-Out Options typically come with lower premiums compared to standard options due to their limited lifespan.
What are the drawbacks of Knock-Out Options?
The major drawback of Knock-Out Options is that they can become worthless even if the underlying asset performs well. This occurs if the knock-out barrier is reached and the option expires before the trader can exercise it. As a result, they come with an inherent risk that the option holder may lose their initial premium even if the market moves in their favor.
Are there different types of Knock-Out Options?
Yes, there are two main types of Knock-Out Options: Up-and-Out and Down-and-Out. An Up-and-Out Option has a knock-out barrier above the current asset price, and it becomes worthless once the asset price rises to that level. A Down-and-Out Option has its knock-out barrier below the current asset price, and expires once the asset price falls to that level.
Can Knock-Out Options be customized?
Yes, Knock-Out Options can be customized according to the specific needs of the trader. The knock-out barrier, expiration date, strike price, and other terms can be adjusted to create a tailored risk management strategy.
Are Knock-Out Options suitable for all investors?
Knock-Out Options are generally more suited for experienced investors and traders due to their complexity and risk profile. Inexperienced or risk-averse investors might find standard options to be more appropriate for their investment strategy. It is essential to understand your risk tolerance and investment objectives before engaging in trading Knock-Out Options.
