What Is the Maximum Value an OTM Option Can Have at Expiration?
The maximum value an Out-of-the-Money (OTM) option can have at expiration is zero. By definition, if an option expires OTM, it has no intrinsic value.
The time value of any option decays to zero at expiration. Therefore, an OTM option will expire worthless, and the premium paid for it will be lost.
