What is a Knock-Out Option?
A Knock-Out Option is a type of barrier option that becomes void if the underlying asset reaches a predetermined price level. Once the barrier is touched, the option “knocks out,” and the holder loses the right to exercise it.
Definition
A Knock-Out Option is an options contract that automatically expires if the underlying asset hits a specified barrier price during the life of the option.
Key Takeaways
- The option becomes worthless once the barrier is breached.
- Knock-out features lower premiums compared to standard options.
- Useful for structured products and controlled-risk strategies.
Understanding Knock-Out Options
Knock-Out Options are popular in advanced derivatives trading due to their built-in risk limitations and reduced premiums. Unlike Knock-In Options—which activate upon barrier contact—Knock-Out Options deactivate when the barrier is reached.
Common types include:
- Up-and-Out: Deactivates if the price rises to the barrier.
- Down-and-Out: Deactivates if the price falls to the barrier.
Investors use these options when they expect the underlying asset to remain within a certain price range. Because of the deactivation risk, knock-out premiums are significantly lower than traditional options.
Formula (If Applicable)
Pricing relies on advanced models such as:
- Modified Black–Scholes
- Monte Carlo simulations
- Analytical barrier models
Real-World Example
A trader buys a down-and-out call on a stock priced at $80 with a barrier at $70. If the stock ever trades at $70 or below during the contract’s life, the option immediately becomes worthless—even if the stock later recovers.
Importance in Business or Economics
Knock-Out Options provide cost-effective exposure with predefined risk boundaries. They are widely used in:
- Corporate hedging
- Structured investment notes
- Foreign exchange products
They help manage volatility while reducing hedging costs.
