Max Pain Options Calculator | What is the Max Pain Theory?

The max pain options point is derived from the maximum pain theory, which states that option buyers who hold their contracts until expiration will lose money. 

Traders can use the max pain point to determine where a stock will gravitate towards at expiration.

Key Takeaways

  • The max pain theory is a concept in options trading that refers to the point at which options traders would experience maximum financial pain or losses if the underlying stock price were to move in a certain direction.

  • Max pain is calculated by analyzing the open interest, or the number of outstanding options contracts, at different strike prices for a given stock or index. The theory is that options market makers and traders will try to push the stock price toward the strike price with the highest open interest in order to minimize their losses and maximize their profits.

  • Max pain can be used as a tool to help traders identify potential support and resistance levels in the market, as well as to inform trading decisions such as the selection of strike prices and the timing of options trades.

What is Max Pain (Options)

The max pain options point is the strike price, where puts and calls have the most open interest. 

Understanding the Max Pain Options Point

The max pain theory states that the stock price will gravitate towards the max pain strike price. As a result, the option sellers will hedge the contracts they sell by buying and selling shares to neutralize their position. 

The option sellers want their options to expire worthless, so they will attempt to buy and sell shares to drive the stock price toward a closing price that will make the option profitable and expire worthless.

For example, consider a market maker who sells a call and put option at the $100 strike price. To get these options to expire worthless, they will sell shares when the price rises above $100 and buy shares when it goes below $100. 

Calculating the Max Pain Point

The max pain point is simple but time-consuming to calculate. The max pain calculation is the sum of the outstanding value of puts and calls for each in the money strike price. 

To calculate the max pain point, follow these steps:

  1. Calculate the difference between the underlying stock price and each in the money strike price.

  2. Multiply the results of step one by the open interest at that strike price.

  3. Find the sum of the dollar value for each put and call at the same strike price.

  4. Repeat these steps for each strike price.

  5. Determine the strike price with the highest dollar value. The result is the max pain price.

Alternatively, the following formula:

  1. For each strike, determine the total intrinsic value among calls, assuming the underlying stock is at that price at the time of expiry

    1. To do this, take the stock price we assume, minus the strike price for each call option with a strike below the assumed stock price

    2. For each call option, multiply this result by the call’s open interest

    3. Add these results for all call options

  2. Do the same for put options

  3. At each strike, add the results we calculated for the calls and puts

  4. The strike with the lowest result is our max pain

Max Pain Options Example

For example, assume that a stock is trading at $100 per share, but lots of open interest is at the $105 strike price. 

According to the max pain theory, the stock price will gravitate towards the $105 price as expiration nears.
