What Is an Options Strangle and How Does It Work?

Options trading involves financial contracts that derive their value from an underlying asset, such as a stock or an exchange-traded fund. These contracts grant the holder a right, but not an obligation, to buy or sell the underlying asset at a predetermined price within a specific timeframe. An options strategy combines multiple options positions to achieve a particular market outlook or risk-reward profile. Among these strategies, a “strangle” is a specific approach that involves simultaneously using both call and put options, designed to potentially profit from significant price movements or stability, depending on the specific type of strangle strategy employed.

Options Fundamentals for Strangle Construction

A call option provides its holder the right to buy an underlying asset at a specified price, known as the strike price, before or on a particular date, the expiration date. Conversely, a put option grants its holder the right to sell an underlying asset at a predetermined strike price, before or on its expiration date. The strike price is the specific price at which the underlying asset can be bought or sold, while the expiration date is the final day an option contract can be exercised. These two components are fundamental to every option contract, dictating its potential value and the timeframe for its validity. These individual option contracts serve as the building blocks for more complex options strategies, including the strangle.

Assembling a Strangle Position

Creating an options strangle involves specific actions with both call and put options. This strategy entails simultaneously buying or selling an out-of-the-money call option and an out-of-the-money put option on the same underlying asset, with the same expiration date. An out-of-the-money call option has a strike price above the current market price of the underlying asset, while an out-of-the-money put option has a strike price below the current market price.

A “long strangle” is established by purchasing both the out-of-the-money call and the out-of-the-money put. This position typically involves paying an upfront premium, which includes brokerage commissions. Conversely, a “short strangle” is created by selling both an out-of-the-money call and an out-of-the-money put. When selling options, the trader receives a premium, which is reduced by any applicable commissions and fees.

Strangle Payoff Dynamics

The financial outcomes of an options strangle depend on the underlying asset’s price movement, time decay, and changes in implied volatility. For a long strangle, the strategy profits from a significant price movement in the underlying asset, either upwards or downwards, beyond certain breakeven points. The upper breakeven point is calculated by adding the total premium paid to the call option’s strike price, while the lower breakeven point is found by subtracting the total premium paid from the put option’s strike price. Maximum profit for a long strangle is theoretically unlimited if the underlying asset’s price rises significantly, and substantial if it falls considerably. The maximum loss for a long strangle is limited to the total premium paid for both options, plus commissions.

In contrast, a short strangle benefits when the underlying asset’s price remains stable and within a specific range, between its two breakeven points. The upper breakeven for a short strangle is the call strike price plus the total premium received, and the lower breakeven is the put strike price minus the total premium received. The maximum profit for a short strangle is limited to the total premium received when establishing the position, minus any commissions. However, the maximum potential loss for a short strangle is theoretically unlimited if the underlying asset moves sharply beyond either breakeven point.

Time decay, also known as theta, erodes the value of options as the expiration date approaches, which is generally disadvantageous for long strangles and favorable for short strangles. Implied volatility, a measure of expected future price fluctuations, also impacts option premiums. An increase in implied volatility generally benefits long strangles by increasing the value of both calls and puts, while a decrease in implied volatility typically benefits short strangles by reducing the value of the sold options.

Market Conditions for Strangle Strategies

Options strangle strategies are typically considered under specific market outlooks or conditions. A long strangle is generally employed when an investor anticipates a significant price movement in the underlying asset but is uncertain about the direction of that movement. For instance, this strategy might be relevant before a major corporate announcement, such as an earnings report or a regulatory decision, where substantial price volatility is expected.

Conversely, a short strangle is often utilized when an investor expects the underlying asset’s price to remain relatively stable within a defined range until the options expire. This strategy is suited for periods of low expected volatility or when the investor believes the market has already priced in anticipated events. The goal is for both the call and put options to expire worthless, allowing the seller to retain the premium collected at the outset.

The role of implied volatility is a significant factor in determining the suitability of these strategies. A long strangle is often more appealing when implied volatility is low, as the options can be purchased at a lower cost, and a subsequent increase in volatility could benefit the position. A short strangle, however, is typically more attractive when implied volatility is high, as the increased premiums collected offer a larger potential profit margin, assuming the underlying asset’s price remains within the expected range.
