Iron Butterfly Definition

An iron butterfly is a limited risk strategy involving four option contracts to earn a limited profit if prices move within the selected range. This options trading strategy is suitable for a less volatile market and keeps traders' investments stable.

Traders use this strategy when they anticipate little change in the underlying asset price until the option contracts' expiry. Iron butterfly consists of four options trades - a bear call spread, a bull put spread, a short call, and a short put options with the same expiry date. Seasoned investors utilize iron butterfly to limit their unlimited risk while making a limited profit. Iron fly is another name for this strategy.

Iron Butterfly Definition

Iron butterfly is an options trading strategy designed to help identify a target price and put and call positions within a specific value range to ensure limited risk and profit.
The three strike prices that investors select include the target price or the middle strike and lower and higher strike prices.
If applied on a not-so-volatile market, the iron fly strategy would assist traders in garnering maximum profits if the stock prices stop at the middle strike price. In addition, it also makes them incur a low loss by hedging against the risk of price fluctuations.
The iron fly strategy restricts a trader's profit and loss by maintaining a better risk to reward ratio. Many experts have suggested that this strategy works best with a seasoned trader who can efficiently balance all the elements.

How Does Iron Butterfly Option Strategy Work?

Trading with options allows traders to make profits from the stock price movements. Call and put are two central elements of options trading. The call option holder has the right to buy an asset for which the call buyer has paid a premium at a strike price. Until the contract's expiry, if the stock price goes beyond the strike price, the call buyer will profit while the call seller will incur a loss.
A put option holder buys an option at a strike price by paying a premium. The put buyer holds the right to sell it until expiry. If the stock price falls below the strike price, the put buyer who is now a put seller will profit when selling. The put buyer will incur a loss.
Trading experts often combine call and put options to limit risks and make profits. Amongst other trading strategies of options, the iron butterfly is a popular one. The iron fly allows traders to trade four different option contracts at three strike prices, including higher, middle, and lower. It comprises two call and put options. Together, they make a butterfly on the trading chart.
The body depicts the selling of one put option and one call option at the same middle strike price (target price). The wings represent buying put and call options. The put option is bought below the target price while the trader purchases the call option above it. They all have the same expiry date. Iron butterfly transactions involve a spread trading strategy where call and put options are combined.
Traders apply the iron fly strategy when they speculate that a stock will trade within a limited price range in a less volatile market. The investors, especially the retail traders, enjoy maximum profits when the asset closes on the middle strike price or the target price. They, however, start incurring heavy losses as soon as the asset prices reach or move beyond their selected range. The iron fly strategy can be short and long.

How To Apply Iron Butterfly Strategy

Iron butterfly is an advanced options trading strategy that can yield higher profits if the underlying asset price equals the middle strike value at expiration. An investor can apply the tactic in the following steps:

Identify a target price for the underlying asset at a strike price.
Sell call and buy options at the stock's current price by selling at the at-the-money price. The strike price becomes the target or the middle strike price.
Buy out-of-the-money (OTM) put option that should be lower than the target price. It becomes the lower strike price. Buying the OTM put increases a trader's risk.
Buy out-of-the-money (OTM) call option higher than the target price. It becomes the higher strike price. Buying the OTM call increases a trader's risk.
OTM purchases here are giving a cushion against unlimited losses.

Examples

Example #1

The strategy creates an opportunity wherein traders can reap smaller limited profits or incur lower maximum potential losses. The calculation of each scenario goes as follows:

Smaller Maximum Profit or Net Credit = Call Option Sold + Put Option Sold – Put Option Purchased - Call Option Purchased

Lower Maximum Loss Possible = Spread – Net Credit

Let us consider that the stock of Clove Inc. is trading at $50 in May 2021. A trader named Mark is interested in making some profit out of it using the iron butterfly strategy.

Mark sells a put option at the middle strike price of $50 (target price) at a premium of $5. He also sells a call option at the same strike price. He pays a premium of $4.

He then decides to purchase a put option at a lower strike price of $40 at the premium of $1.50.

Next, he purchases a call option at a higher strike price of $60 by paying $1.75. The cushioning against the unlimited risk will come through these two purchases.

Smaller Maximum Profit or Net Credit = $5 + $4 – $1.75 - $1.50 = $8.75
The spread is $10, as $60 – $50 = $50 – $40, i.e. 10.
Lower Maximum Loss Possible = $10 – $8.75 = $1.25

The breakeven points that talk about risk making positions in an iron butterfly strategy are as follows –

Target Price + Net Credit = $50 + $8.75 = $58.75
Target Price – Net Credit = $50 - $8.75 = $41.25

One will start incurring a heavy loss if the stock price rises to and beyond $ 58.75. Similarly, one would begin incurring a heavy loss if the stock price goes down to $41.25 and beyond.

As long as the price stays in the above range or at the target price, one would profit.

Example #2

Alice is a seasoned iron fly investor. She decides to buy put and call options. First and foremost, she starts by identifying the at-the-money target price. Two more OTM strike prices follow next. They all share the same expiry. She then buys put and call options. The price fluctuates beyond her safety net but soon enough comes back due to less volatility bringing her profit.

Iron Butterfly vs Iron Condor

Both iron butterfly and iron condor are options trading strategies and have their own set of pros and cons.

The iron butterfly strategy uses four options with three strike prices for low risk and limited-profit chances. The iron condor also utilizes four options available to traders with two put spreads and two call spreads but at four different strike prices.

The stock price movement stops and closes at the target strike price, in such a case, the returns from the iron butterfly technique are usually higher.

Let us have a look at the differences between the two strategies.

Iron Butterfly	Iron Condor
It has an at-the-money target strike price.	It usually has a slightly out-of-the-money target stick price.
Three strike prices.	Four strike prices.
Narrow structure.	Broader structure.
Maintains better reward to risk ratio.	More likely to gain profits.
