What is an Iron Butterfly?
An Iron Butterfly is a sophisticated options trading strategy that enables traders to capitalize on stock or futures price movements within a specified range, all while taking advantage of decreasing implied volatility. This strategy is often employed during periods of sideways market movements or mild upward trends and is affectionately known as the “Iron Fly.”
How an Iron Butterfly works
The Iron Butterfly strategy is crafted with precision, involving a quartet of options – two call options and two put options – distributed across three strike prices, all with the same expiration date. The main goal is to secure gains when the price of the underlying asset remains relatively stable and both implied and historical volatility show signs of diminishing.
This strategy can be visualized as a fusion between a short straddle and a long strangle. The short straddle is positioned at the middle strike price, while the long strangle spans two additional strikes above and below the central strike.
Here’s a step-by-step guide on how to construct an Iron Butterfly trade:
- Identify the target price, which signifies the level at which you anticipate the underlying asset will settle on a specific future date.
- Select options that expire around the same time as your target date.
- Purchase an out-of-the-money call option with a strike price considerably higher than your target.
- Sell both a call and a put option with strike prices closest to your target.
- Acquire an out-of-the-money put option with a strike price well below your target.
The chosen strike prices in steps two and three should provide sufficient room to accommodate a range of potential price movements in the underlying asset, enhancing the likelihood of a successful trade outcome.
Deconstructing the Iron Butterfly
The Iron Butterfly strategy is intentionally designed with limited upside profit potential. It operates as a credit-spread strategy, meaning that traders initially sell option premiums and receive a credit for the value of these options at the beginning of the trade. The ultimate goal is for these option values to decline or expire worthless, allowing traders to retain as much of the initial credit as possible.
However, it’s crucial to be mindful of commission costs, as this strategy involves the use of four options. High commissions can significantly impact the overall profitability of the trade, so prudent management of these costs is essential to maximize returns.
Iron Butterfly trade example
To illustrate the Iron Butterfly strategy in action, let’s consider an example involving a trader who anticipates a slight rise in the price of IBM shares over the next two weeks while also expecting a decline in implied volatility. The trader initiates an Iron Butterfly trade, initially collecting a net credit of $550. For this trade to be profitable, the price of IBM shares should remain within the range of 154.50 and 165.50 at the time of expiration.
If the price indeed stays within this range near expiration, the trader has the option to close the trade early for a profit. This involves selling the call and put options initially purchased and buying back the call and put options sold at the beginning of the trade. Many brokers facilitate this process with a single order.
Additionally, there is another intriguing trading opportunity if the price of IBM shares remains below $160 on the expiration day. In such a scenario, the trader may have the shares of IBM (100 per put contract sold) put to them at a price of $160 per share.
For example, if the closing price of IBM is $158 per share on the expiration day, the trader would be obligated to purchase the shares for $160. However, considering the initial credit received of $5.50 per share, the net transaction can be viewed differently. In this light, the trader effectively purchased IBM shares while simultaneously collecting a $2.50 profit per share ($5.50 credit minus $2.00).
It’s worth noting that most aspects of the Iron Butterfly strategy can be achieved through trades involving fewer options legs, resulting in lower commission costs. While other strategies like selling naked puts or buying put-calendar spreads have their advantages, the Iron Butterfly provides an added layer of protection against steep downward price moves, which the naked put strategy lacks. Furthermore, this strategy benefits from the decline in implied volatility, a characteristic that the put-calendar spread cannot replicate.
The bottom line
The Iron Butterfly is an advanced options trading strategy that offers traders an opportunity to profit in stable market conditions while benefiting from decreasing implied volatility. By combining four different option contracts and strategically positioning them across three strike prices, this strategy aims to capture gains within a specified price range. While it has limited upside profit potential, it provides protection against sharp downward price movements. However, traders should be vigilant about commission costs, as they can impact overall profitability. When considering the Iron Butterfly, it’s essential to understand its mechanics and carefully manage the associated risks and costs. This strategy can be a valuable addition to a trader’s toolkit, particularly in markets characterized by low volatility and stable price movements.
