What is max pain in options?

Max pain is the strike price at which the most option value expires worthless. At that price, option buyers collectively lose the most and option sellers keep the most premium, hence the point of maximum pain for holders.

How it is calculated

Max pain is worked out from open interest. For each possible expiration price, you add up the intrinsic value of every in-the-money call and put, weighted by how many contracts are open at that strike. Do this across all strikes and the price where the total intrinsic value is lowest is max pain, because that is where the fewest dollars flow to option holders.

The theory behind it

The idea is that market makers who sold those options hedge their books, and that hedging can nudge the stock toward the strike where the most contracts expire worthless, especially as monthly expiration approaches and open interest is large. It is a rough gravitational pull, not a mechanism that forces price to a level.

Its limits

• Open interest lags. OI is published the next morning, so today's max pain is based on yesterday's settled positioning.
• It is weak on short horizons. The pull, where it exists at all, is strongest into monthly opex and unreliable day to day.
• Trends override it. Real news and strong trends blow straight through max pain. It is context, not a price target.

How MomentumSift shows it

MomentumSift computes max pain from the chain's open interest and shows it with the full OI ladder by strike, the put/call ratio, and the largest call and put walls drawn on the price chart as levels.

FAQ

What does max pain mean?

The strike where the most option value expires worthless, so buyers lose the most and sellers keep the most premium.

How is it calculated?

Sum the intrinsic value of all in-the-money calls and puts weighted by open interest at each price; the lowest total is max pain.

Do stocks really pin to max pain?

Sometimes into monthly expiration, but it is a tendency, not a law. Treat it as context, not a target.
