Introduction to Options Trading Strategies: Butterfly Spread

Updated: Feb 18

The world of options trading is rich and diverse, with a multitude of strategies for different risk profiles and market conditions. One such strategy that often gets attention is the 'Butterfly Spread'. In this article, we'll delve into what a butterfly spread is, why you might use it, and provide a detailed example to help you understand this strategy in practice.

What is a Butterfly Spread?

The butterfly spread is a neutral strategy in options trading, which means that it works best when the underlying asset's price stays within a specified range. Investors utilize this strategy when they anticipate that the price of an underlying asset will not experience significant movement. It involves the simultaneous purchase and sale of options contracts with the same expiration date but different strike prices. The Butterfly spread can be implemented using either call options or put options, resulting in a 'Call Butterfly Spread' or a 'Put Butterfly Spread.' In its simplest form, the strategy requires the creation of four options contracts, including two at the money (ATM), one in the money (ITM), and one out of the money (OTM).

Why use a Butterfly Spread?

The primary reason for implementing a butterfly spread is to profit from the minimal movement in the underlying asset's price. This strategy allows traders to generate income with limited risk, making it appealing for conservative investors or in low-volatility market environments. Furthermore, the butterfly spread has limited downside risk. The maximum loss that an investor can incur is the net premium paid for the options. Thus, the butterfly spread is a great strategy for managing risk while generating a decent potential profit.

Understanding the Butterfly Spread through an Example

Let's assume you believe that XYZ Company's stock, currently trading at $50, will not experience significant price movement over the next month. To capitalize on this market prediction, you could create a butterfly spread.

  • Buy an ITM Call: You start by buying a call option with a strike price of $45, costing $6.50 per share, or $650 per contract (options contracts typically represent 100 shares of the underlying stock).

  • Sell two ATM Calls: Next, you sell two call options at the strike price of $50. Let's say these options bring in a premium of $4.00 per share, or $400 per contract. As you've sold two contracts, you've collected $800.

  • Buy an OTM Call: Finally, you buy another call option, but this time at a higher strike price of $55. This option costs $2.50 per share, or $250 per contract.

To establish this position, your total outlay (ignoring commissions and fees) would be the cost of the bought options minus the premium received from the sold options: ($650 + $250) - $800 = $100. Your maximum potential loss is limited to the net premium paid ($100). The maximum profit is the difference between the strike prices of the sold and bought calls less the net premium paid, or ($50 - $45 - $1) x 100 = $400. This maximum profit is realized if the stock price is exactly at the strike price of the short calls at expiration, i.e., $50. If the stock price is below $45 or above $55 at expiration, all options would expire worthless, and you would lose the net premium paid. For prices between $45 and $50, or $50 and $55, the profit or loss would vary.

The butterfly spread is an advanced options trading technique aimed at capitalizing on low fluctuations in the underlying asset. As a neutral strategy with a restricted risk spectrum, it could be a favorable approach under particular market circumstances. However, there might be instances where it becomes necessary to adjust or exit your butterfly spread position, despite its potential efficacy under specific market dynamics.

Adjusting a Butterfly Spread

Let's say the underlying stock price starts to move out of the desired range, posing a threat to your maximum profit potential. One way to respond to this situation is to adjust the position by 'rolling' the spread. Rolling involves closing the current position and opening a new one at a different strike price. For instance, if XYZ stock started to rise significantly, you might decide to roll the butterfly spread up. This would involve closing the current spread and then re-establishing it with the call options' strike prices set higher. Remember, every adjustment involves more transactions, and therefore, more transaction costs. It's important to consider these costs before making an adjustment.

Exiting a Butterfly Spread

As with any options strategy, it's crucial to have an exit plan in place. One common approach is to exit the butterfly spread before the expiration date to avoid unpredictable price movement on the last day of trading. If the stock price is near the middle strike price, closing the position a few days before expiration could be profitable, considering the time decay accelerates as the expiration day nears. However, if the stock price has moved significantly away from the middle strike price, it may be better to simply allow the options to expire worthless, especially if the cost of closing the position exceeds the remaining risk.

Risks and Rewards

Like any investment strategy, butterfly spreads come with both potential rewards and risks. On the reward side, butterfly spreads can be a cost-effective way to profit from range-bound stocks, with the maximum potential profit often considerably higher than the initial outlay. However, the main risk of a butterfly spread is that the underlying stock will move significantly in either direction, leaving the options either worthless or reducing the potential profit. Butterfly spreads are also more complex than simple options strategies such as buying a call or put, so they require a good understanding of options trading.

Butterfly spreads are an important part of the options trader's toolbox, offering a way to profit from range-bound stocks with limited risk. However, they also require a detailed understanding of options and careful management, particularly in terms of adjusting and exiting positions. As always, it's important to understand a strategy fully before implementing it and to always have a clear exit plan in place.
