What is Max Pain in Options Trading?
Max pain, also known as the max pain strike price, is the strike price where option buyers lose the most money and option sellers (market makers) profit the most at expiration. This theory suggests that the underlying stock price tends to gravitate toward the max pain strike as expiration approaches.
How Max Pain is Calculated
The max pain calculation involves analyzing open interest across all strike prices for a given expiration date:
- For each strike price, calculate the total dollar value lost by option holders if the stock closes at that strike
- Sum the losses for both call and put options at each strike
- The strike with the highest total loss for option buyers is the max pain strike
