Strangle
A strangle is an advanced options trading strategy that involves the simultaneous purchase or sale of both a call and a put option with the same expiration date but different strike prices. This approach allows traders to capitalize on significant price movements in an underlying asset, regardless of the direction of the move. The key difference between a strangle and a similar strategy known as a straddle is that, in a strangle, the strike prices of the call and put options are different.
Introduction to the Strangle Strategy
Defining the Strangle
In a strangle strategy, the trader buys (long strangle) or sells (short strangle) both an out-of-the-money call and an out-of-the-money put option. These options have identical expiration dates but different strike prices, which are usually equidistant from the current price of the underlying asset. For instance, consider an underlying stock trading at $100. A trader might buy a $105 call option and a $95 put option simultaneously. This setup allows the trader to profit from large price movements without knowing the direction of those movements beforehand.
Long Strangle
- Objective: The trader aims to profit from significant volatility in the underlying asset.
- Execution: Purchase an out-of-the-money call and an out-of-the-money put.
- Cost: The total cost is the sum of the premiums paid for both options.
- Profit Potential: Unlimited potential on the upside (due to the call option) and substantial on the downside (subject to the price of the underlying asset going to zero).
- Risk: The maximum risk is limited to the total premium paid.
Short Strangle
- Objective: The trader aims to profit from low volatility, expecting the price of the underlying asset to remain stable.
- Execution: Sell an out-of-the-money call and an out-of-the-money put.
- Cost: The trader receives the total premiums from selling both options.
- Profit Potential: Limited to the total premiums received.
- Risk: Potentially unlimited risk on the upside (due to the call option) and substantial on the downside (subject to the price falling significantly due to the put option).
Mechanics of a Strangle
Premium Calculation
The premium of an option is its price in the market. For a strangle, the combined premium is the sum of the premiums for both the call and put options. The size of the premium directly affects the potential profit and loss of the strangle trade.
Breakeven Points
For a long strangle, the breakeven points are calculated as follows:
- Upper Breakeven Point: Strike price of the call option + Total premium paid.
- Lower Breakeven Point: Strike price of the put option - Total premium paid.
For a short strangle, the breakeven points are:
- Upper Breakeven Point: Strike price of the call option + Total premium received.
- Lower Breakeven Point: Strike price of the put option - Total premium received.
Profit and Loss
Long Strangle:
- Profit: Realized when the price moves significantly above the upper breakeven point or significantly below the lower breakeven point.
- Loss: Limited to the total premium paid. Occurs when the underlying asset’s price stays between the strike prices of the two options.
Short Strangle:
- Profit: Limited to the total premium received. Occurs when the underlying asset’s price stays between the strike prices of the two options.
- Loss: Potentially unlimited if the price moves significantly above or below the breakeven points.
Use Cases and Market Conditions
Volatility
A strangle strategy is highly dependent on market volatility. For a long strangle, traders exploit high volatility, which can lead to large price swings. Conversely, a short strangle benefits from low volatility or a stable market scenario where significant price changes are unlikely.
Earnings Reports and Major Announcements
Long strangles are particularly popular around major corporate announcements or earnings reports. These events tend to cause substantial price movements, and a long strangle strategy can capitalize on such volatility without predicting the direction of the movement.
Limitations
High Premium Costs
The main limitation of a long strangle is the high premium costs. Since the strategy involves buying two options, the upfront cost can be substantial, making the strategy less attractive if the anticipated volatility does not materialize.
Risk of Unlimited Losses
For a short strangle, the potential for unlimited losses makes it a highly risky strategy, suitable only for experienced traders with a strong assessment of market stability.
Advanced Strategies
Iron Condor
An iron condor is a more advanced strategy that builds on the principles of a strangle. It involves the purchase and sale of four options with different strike prices. Essentially, it combines a bull put spread and a bear call spread to limit both the potential profit and the risk. This strategy offers a way to execute a strangle-like approach but with capped risk.
Adjustments and Rollovers
Traders often adjust their strangle positions based on market conditions. Adjustments can involve rolling options to later dates, changing strike prices, or converting the position into a different strategy to manage risks and capitalize on new market conditions.
Real-World Examples
Example of a Long Strangle
- Underlying Asset: Stock trading at $100
- Options Purchased:
- $105 Call option premium: $2
- $95 Put option premium: $3
- Total Premium Paid: $2 + $3 = $5
- Breakeven Points:
- Upper: $105 + $5 = $110
- Lower: $95 - $5 = $90
If the stock price moves to $115, the profit will be ($115 - $105) - $5 = $5.
Example of a Short Strangle
- Underlying Asset: Stock trading at $100
- Options Sold:
- $105 Call option premium: $2
- $95 Put option premium: $3
- Total Premium Received: $2 + $3 = $5
- Breakeven Points:
- Upper: $105 + $5 = $110
- Lower: $95 - $5 = $90
If the stock price stays at $100, the profit will be the total premium received = $5.
Tools and Platforms
Many trading platforms and tools exist to assist traders in executing strangle strategies. Among them, automated trading systems and algorithmic trading have become increasingly popular. These systems can be programmed to place strangle trades when certain market conditions are met, removing the need for manual intervention.

Regulatory Considerations
Options trading is subject to regulatory oversight to ensure fair practices and transparency. Regulatory bodies such as the Securities and Exchange Commission (SEC) in the United States impose specific rules on options trading. Traders must adhere to margin requirements, disclosure obligations, and reporting standards. Understanding these regulations is crucial for both legal compliance and risk management.
Conclusion
The strangle is a versatile options trading strategy that appeals to traders seeking to profit from significant price movements in an underlying asset, irrespective of the direction. By understanding its mechanics, use cases, and limitations, traders can deploy strangles effectively to align with their market outlook and risk tolerance. Whether executed manually or through automated trading systems, strangles offer a compelling approach for navigating both volatile and stable market conditions.
