What is Max Pain?
Max Pain is the strike price at which option sellers (market makers) would lose the least amount of money if the stock expired at that price. The theory suggests stocks tend to gravitate toward this price near expiration.

Understanding MRK Max Pain
The MRK options chain represents Merck. Evaluate its open-interest distribution alongside business context that includes drug demand, clinical results, regulation, and product pipelines. Compare Max Pain across available expirations because the distribution can differ from one expiration to another.
For MRK, the calculator tests each candidate strike against call and put open interest for the selected expiration. Review the full curve with the result. The calculation describes the selected chain and does not predict where Merck will trade.
How the MRK Max Pain calculation works
QuantWheel tests each strike as a possible expiration price. It adds the intrinsic value of open calls and puts at that price, weighted by open interest and the contract multiplier. The strike with the lowest combined value is displayed as MRK Max Pain.
This calculation uses the selected options chain. It does not measure dealer inventory, intent, future order flow or the probability that MRK will finish at the calculated strike.

MRK Max Pain FAQ
What is MRK Max Pain?
MRK Max Pain is the candidate expiration price where the combined intrinsic value of outstanding MRK calls and puts is lowest for the selected expiration. It is a calculation based on open interest, not a prediction of where MRK will trade.
How is MRK Max Pain calculated?
For each candidate price, QuantWheel calculates call and put intrinsic value across the selected MRK options chain, multiplies each value by open interest and the 100-share contract multiplier, then adds the totals. The candidate price with the lowest combined total is the Max Pain strike.
Which MRK expiration should I select?
Select the exact MRK expiration you want to examine. Weekly and monthly expirations can have different open-interest distributions, so compare them separately instead of applying one result to every date.
How should I use MRK Max Pain?
Compare the calculated strike with MRK price and the full call and put pain chart for the same expiration. Use it as expiration context alongside liquidity, gamma exposure and your own risk plan rather than as a standalone trading signal.
Is MRK Max Pain a price target?
No. MRK Max Pain does not forecast price and does not prove that traders or market makers will move MRK toward a particular strike. News, volatility, liquidity and positioning can outweigh any expiration-related pinning effect.
Is the MRK Max Pain calculator free?
Yes. QuantWheel provides a limited number of free MRK Max Pain calculations. The calculator shows how many free calculations remain before you run another expiration.
