What Is a Barrier Option?
Barrier options are derivatives whose payoff relies on the underlying asset reaching a set price point. There are two main types: knock-out options, which become worthless if limits are breached, and knock-in options, gaining value only once a specific price is achieved. These options provide unique benefits and strategic uses for traders.
Barrier options are considered exotic options because they are more complex than basic American or European options. Barrier options are also considered a type of path-dependent option because their value fluctuates as the underlying value changes during the option’s contract term. In other words, a barrier option’s payoff is based on the underlying asset’s price path. The option becomes worthless or may be activated upon the crossing of a price point barrier.
Key Takeaways
- Barrier options are financial derivatives where the payoff depends on whether the underlying asset reaches a specified price barrier.
- Knock-in options become valid only if the underlying asset hits a predetermined barrier during the option’s life.
- Knock-out options terminate if the underlying asset reaches a predetermined barrier, causing the option to become worthless.
- Barrier options offer lower premiums than standard options, making them cost-effective for hedging or speculative trading.
- Variants like rebate barrier options, turbo warrants, and Parisian options provide different triggers and payoff structures within the barrier options category.
Exploring the Two Main Types of Barrier Options
Barrier options are typically classified as either knock-in or knock-out.
Understanding Knock-in Barrier Options
A knock-in option is a type of barrier option where the rights associated with that option only come into existence when the price of the underlying security reaches a specified barrier during the option’s life. Once a barrier is knocked in, or comes into existence, the option remains in existence until it expires.
Knock-in options may be classified as up-and-in or down-and-in. In an up-and-in barrier option, the option only comes into existence if the price of the underlying asset rises above the pre-specified barrier, which is set above the underlying’s initial price. Conversely, a down-and-in barrier option only comes into existence when the underlying asset price moves below a pre-determined barrier that is set below the underlying’s initial price.
Decoding Knock-out Barrier Options
Contrary to knock-in barrier options, knock-out barrier options cease to exist if the underlying asset reaches a barrier during the life of the option. Knock-out barrier options may be classified as up-and-out or down-and-out. An up-and-out option ceases to exist when the underlying security moves above a barrier that is set above the underlying’s initial price. A down-and-out option ceases to exist when the underlying asset moves below a barrier that is set below the underlying’s initial price. If an underlying asset reaches the barrier at any time during the option’s life, the option is knocked out, or terminated.
Additional Variants of Barrier Options
Other variants of the barrier options described above are possible. Here are three of them:
- Rebate Barrier Options: Both knock-out and knock-in barrier options can contain a provision to provide rebates to holders if the option does not reach the barrier price and becomes worthless. Such options are known as rebate barrier options. Rebates, in such cases, take the form of a percentage of the premium paid by the holder for the option.
- Turbo Warrant Barrier Options: Mainly traded in Europe and Hong Kong, Turbo warrants are a type of down-and-out option that is highly leveraged and is characterized by low volatility. They are popular in Germany and are used for speculation purposes.
- Parisian Options: In a Parisian option, reaching the barrier price does not trigger the contract. Instead, the underlying asset’s price has to spend a pre-defined amount of time beyond the trigger barrier price for the contract to kick in. The amount of time that the underlying asset’s price spends outside and inside the barrier price range is measured in this type of option.
Why Consider Trading Barrier Options?
Barrier options often have cheaper premiums because of their added conditions. If a trader thinks the barrier won’t be reached, they might choose a knock-out option for its lower premium.
A trader wanting to hedge only if the underlying hits a certain level might use knock-in options. The lower premium of the barrier option may make this more appealing than using non-barrier American or European options.
Examples of Barrier Options
Here are two examples of barrier options described above.
Knock-in Barrier Option
Assume an investor purchases an up-and-in call option with a strike price of $60 and a barrier of $65, when the underlying stock is trading at $55. The option would not come into existence until the underlying stock price moved above $65. While the investor pays for the option, and the potential that it could become valuable, the option only becomes applicable if the underlying reaches $65. If it doesn’t, the option is never triggered and the option buyer loses what they paid for the option.
Knock-out Barrier Option
Assume a trader purchased an up-and-out put option with a barrier of $25 and a strike price of $20, when the underlying security was trading at $18. The underlying security rises above $25 during the life of the option, and therefore, the option ceases to exist. The option is now worthless, even if it only touched $25 briefly and then dropped back below.
What Are Exotic Options?
An exotic option is a type of derivative contract that differs from the more traditional American and European options in their payment structure, expiration date, and strike price. Exotic options are also more complex, provide more investment alternatives, and can be customized to meet the investor’s risk tolerance and goals.
What’s the Difference Between American and European Options?
An American option allows holders to exercise their rights at any time before and including the expiration date. A European option, on the other hand, only allows execution on the day of expiration.
What Are the Benefits of Barrier Options?
The main advantage of barrier options is that they have lower premiums for the option buyer than standard options. They also carry less risk for the option seller and provide investors with more freedom and flexibility to set the terms of their contracts.
The Bottom Line
Barrier options are complex derivatives with payoffs contingent on the underlying asset’s price crossing specific barriers. These can be knock-in, which activate upon reaching the barrier, or knock-out, which become void. Variants include rebate options that offer partial refunds, turbo warrants highly favored for leveraging, and Parisian options that consider time spent beyond the barrier. Their main advantage lies in offering lower premiums than standard options, making them cost-effective for hedging or speculative strategies. Traders can tailor these options to match specific market views, leveraging their unique conditions for optimal outcomes.
