Option Pain Theory

Lesson Content

Option Pain Theory, also known as Max Pain Theory, suggests that option prices tend to move in a direction that causes maximum financial loss to option buyers. This occurs because market makers, who are the counterparties to most option trades, have an incentive to push the underlying asset's price toward the strike price where the most options expire worthless. In the Indian market context, consider Nifty options at expiry. If a large number of call options are open at 18,500 strike price and put options at 18,000, the theory suggests Nifty may gravitate toward a point where both sets of options expire worthless, causing maximum pain to option buyers. This doesn't mean the market manipulates prices, but rather that market makers hedge their positions in ways that often lead to this outcome. For example, during Reliance Industries' quarterly results, if heavy put open interest is built at 2,400 and call open interest at 2,600, the stock price might find support near 2,500 to maximize losses for option holders.
