European style options are derivative contracts that grant the holder the right, but not the obligation, to buy or sell an underlying asset at a predetermined price. The defining characteristic of this option type is its restriction on exercise timing. Unlike American options, which permit exercise at any point before expiration, European options can only be exercised on the final settlement date. This constraint simplifies the valuation process significantly.
Exercise
The exercise mechanism for European options is strictly limited to the expiration date. This constraint simplifies the valuation process significantly, as there is no early exercise premium to consider. The option’s value is determined solely by the underlying asset’s price relative to the strike price at the moment of expiration. The holder must wait until expiration to realize any intrinsic value.
Valuation
The valuation of European options is typically performed using models like Black-Scholes, which assume a single exercise point. This simplification allows for more straightforward calculation of option Greeks and theoretical pricing. The inability to exercise early means the option holder must wait until expiration to realize any intrinsic value. This characteristic makes them easier to model mathematically than American options.
