OTM, or Out of the money, is an expression that refers to an option that only contains extrinsic value.
A call option is OTM if the strike price is above the price of the equity in question.
Example: With AAPL trading at $182.50 a 190C would be ‘out of the money.’
A put option is OTM if the strike price is below the price of the equity in question.
Example: With AAPL trading at $182.50 a 175p would be ‘out of the money.’
An option can also be in the money (ITM) or at the money (ATM).
