PLEASE READ THESE DISCLAIMERS:
The Greeks represent the consensus of the marketplace as to how the option will react to changes in certain variables associated with the pricing of an option contract. While Delta represents the consensus of the marketplace as to the theoretical price movement of the option relative to the underlying security there is no guarantee that either of these forecasts will be correct.
While Theta represents the consensus of the marketplace as to the amount a theoretical option’s price will change for a corresponding one-unit (day) change in the days to expiration of the option contract there is no guarantee that this forecast will be correct.
