Report Date: 3-Jan-2025

Use this screener to evaluate current at-the-money straddle values against historical theo values. We compare the current market price of the straddle (bid and offer) to a theoretical value created by analyzing results of a historical price return distribution.

The risk of selling options is not limited to the initial cost of the straddle. The risk tab shows the amount at risk for the straddle given multiple high-risk scenarios for the stock price.

Use the Filter choices to narrow your search by Expiration Date, Stock Type, Market Cap, Average Volume, and several others.

Over Selected Timeframe		 Amount At Risk Selling certain option strategies produces greater risk than simply the cost of the option. If you sell a call, for instance, the potential loss is infinite -- the price could just keep going up. Here, you see a breakdown of the potential amount at risk for each straddle below. When buying straddles, the risk is fixed -- just the amount you paid for the straddle. When selling, the potential risk is greater, so we use three metrics to compare risk. Risk to Premium Ratio When selling straddles, this is the ratio of the amount at risk divided by the amount received (the initial market price of the straddle)

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 strategy based on those historical changes in stock price

Theoretical Edge:

Using the historical distribution, we calculate a theoretical value of the current straddle 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 straddle.

Theoretical Win Rate

Using the historical distribution, win rate represents the percentage of these historical observations where the current straddle would have resulted in a positive return (given the observed change in stock price over the specified holding period).

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.
