The cash value graph shows the result of the cash value max pain calculation. The yellow highlighted
column indicates the max pain option strike. The max pain cash value calculation uses the Open Interest
to determine the cash paided out by the option writers if the stock were to close at each strike. For
details on how the cash value max pain point is derived, please visit the calculation page.
Please note the open interest is updated daily prior to the market open. It is not updated intra-day.
This page uses Yahoo Finance and similar sources for option data. The open interest data for the stock options
is compiled nightly. Open Interest data is therefore valid prior to the market open, before the CBOE begins
trading options each day. After the market opens and options begin trading the open interest data may no longer
by valid. No option data source provides intra-day open interest. The only intra-day data available is the
The underlying option data, including open interest and cash values, can found on the Option Data page.
The numbers across the bottom represent the various strike prices of the stock options. Max Pain is calculated
for each strike by determining the cash value paid out on each call and put option at that strike. The red
vertical bar is the put option cash value. The green vertical bar is the call option cash value. The further
away the stock price is from the max pain point the more the option writers will have to pay out. Conversely,
the closer to the max pain point the stock price is the less they pay out.
Max pain theory ays that the option writers will hedge the contracts they have written. In the case of the market
maker, the hedging is done to remain neutral in the stock. Consider the market makers position if he must write
an option contract without wanting a position in the stock. As the maturity date approaches, the stock price
changes. In addition, contracts may be closed by the option buyers. As a result the option writer must rebalance
his hedges. This rebalancing is an effort to hedge the open contracts, thus maintaining a state where the least
amount of money will be paid out. Rebalancing of positions in the stock provide pressure on the price to close at
the max pain point.
