Concept
Max Pain
Max pain is the strike price at which the total value of outstanding options expiring worthless would be greatest — equivalently, where option buyers collectively lose most. It is computed from open interest across strikes.
How to read it
- The calculation sums, for each candidate strike, the intrinsic value that all outstanding calls and puts would carry if the underlying settled there. The strike producing the lowest total payout is the max pain point.
- It moves as open interest shifts, so the figure changes through the expiry cycle.
- The theory holds that price tends to gravitate toward this strike near expiry.
What it does not tell you
- The claimed mechanism requires participants with both the ability and the incentive to move an index toward a strike. On liquid index options the capital required makes this difficult to substantiate.
- Settlement near max pain is frequently cited as confirmation, but max pain tends to sit near the prevailing price anyway — because that is where open interest concentrates. The two being close is partly definitional.
- It is computed from open interest that does not distinguish buyers from sellers or hedges from speculation.
Frequently asked questions
What is max pain in options?
The strike at which the combined payout to outstanding option holders would be smallest if the underlying settled there. It is derived from open interest across strikes.
Does price really move to max pain?
Settlements often land near it, but max pain generally sits near the prevailing price because that is where open interest gathers. Closeness is therefore weak evidence for the causal claim.
How is max pain calculated?
For each strike, sum the intrinsic value all outstanding calls and puts would have if the underlying settled there. The strike with the lowest total is the max pain strike.
Should I trade based on max pain?
What to trade is your decision and outside what this page addresses. What can be said is that the mechanism behind the theory is contested and the supporting evidence is largely observational.
