Debit Iron Butterfly Spread Screener (Long ATM Strike, Short OTM Strikes)
Report Date: 15-Apr-2024
Debit Iron Butterfly Spreads involve selling both an out-of-the-money call and an out-of-the-money put, while buying an at-the-money call and an at-the-money put (on the same strike) for a particular expiration of a selected underlying asset. Because you are buying two higher-premium options and selling lower-premium ones, the strategy requires a net outlay of premium at the time of the trade.
The goal for this strategy would be for the stock price to have a big swing away from the current spot price (in either direction). The maximum loss is experienced when the stock price at expiration is right at the strike price of the specified at-the-money strike.

Market Price The net outlay in option premium by executing this spread trade. Because the options you're buying are a higher cost than the options you're selling, you are paying out the net difference in prices. This amount also corresponds to the maximum loss you can experience from the spread. |

About Historical Distributions
We compile an interval-based historical price return distribution for the underlying stock
If there are 20 days to go until expiration, we go back historically and look at intervals with a 20-day holding period for changes in stock price
If there is an earnings date coming up before expiration, we look at only those historical periods that included an earnings date
Similarly, if there is no earnings date before expiration, we look at only historical periods without earnings
We use those intervals to calculate a theoretical value for the spread based on those historical changes in stock price

Theoretical Value & Edge
Using the historical distribution, we calculate a theoretical value of the current spread based on these past changes in stock price.
To determine the edge, we take that value and compare it to the current market price of the spread.
Theoretical Win Rate
Using the historical distribution, win rate represents the percentage of these historical observations where the current spread would have resulted in a positive return (given the observed change in stock price over the specified holding period).
This means that the end value of the spread would have been greater than the initial cost of the spread (Debit).
Dynamic IV Range Modeling
For the historical distribution, we've implemented a new model utilizing dynamic implied volatility ranges to narrow results around the symbol's current volatility environment. The implied volatility (IV30) is recorded at the start of each historical interval. We only select the 50% of historical observations where the IV30 at the time of the observation is the closest to the current IV30 -- 25% above and 25% below.
This way, if the current IV30 is exceptionally high or exceptionally low, we are focusing only on other historical observations that showed similar volatility.
We only utilize this method if we can ensure at least 16 observations. Otherwise, we continue to use all historical observations, as was the case prior to this method being applied.
