There are other proxies for moneyness, with convention depending on market. Though the above is a traditional way of calculating ITM, OTM and ATM, some new authors find the comparison of strike price with current market price meaningless and recommend the use of Forward Reference Rate instead of Current Market Price. For example, the option will be In The Money if Strike Price of Buy PUT on underlying is greater than the Forward Reference Rate. It partly arises from the uncertainty of future price movements of the underlying. A component of the time value also arises from the unwinding of the discount rate between now and the expiry date. An at-the-money option has no intrinsic value, only time value.

For example, with an “at the money” call stock option, the current share price and strike price are the same. Exercising the option will not earn the seller a profit, but any move upward in stock price will give the option value. A call option is in the money when the strike price is below the spot price. A put option is in the money when the strike price is above the spot price.

With an “in the money” call stock option, the current share price is greater than the strike price so exercising the option will give the owner of that option a profit. A call option is out of the money when the strike price is above the spot price of the underlying security. A put option is out of the money when the strike price is below the spot price. With an “out of the money” call stock option, the current share price is less than the strike price so there is no reason to exercise the option. The owner can sell the option, or wait and hope the price changes.

One can also talk about moneyness with respect to the forward price: thus one talks about ATMF, “ATM Forward”, and so forth. JPY is 120, and the forward price one year hence is 110, then a call struck at 110 is ATMF but not ATM. Buying an ITM option is effectively lending money in the amount of the intrinsic value. Consequently, ATM and OTM options are the main traded ones. Somewhat different formalizations are possible. Further axioms may also be added to define a “valid” moneyness.

There are thus two conventions, depending on direction: call moneyness, where moneyness increases if spot increases relative to strike, and put moneyness, where moneyness increases if spot decreases relative to strike. Switching spot and strike also switches these conventions, and spot and strike are often complementary in formulas for moneyness, but need not be. Which convention is used depends on the purpose. While moneyness is a function of both spot and strike, usually one of these is fixed, and the other varies. This section outlines moneyness measures from simple but less useful to more complex but more useful. In practice, for low interest rates and short tenors, spot versus forward makes little difference.

OTM corresponding to switching sign. The above measures are independent of time, but for a given simple moneyness, options near expiry and far for expiry behave differently, as options far from expiry have more time for the underlying to change. This is often small, so the quantities are often confused or conflated, though they have distinct interpretations. The percent moneyness is the implied probability that the derivative will expire in the money, in the risk-neutral measure. 2, which is the reason for the correction factor.

Delta, is subtler, and can be interpreted most elegantly as change of numéraire. Delta is higher than moneyness. 2 How Can We Define Moneyness?
