Early Exercise Premium

Calculation

The Early Exercise Premium represents the time value embedded within an American-style option, quantifying the advantage of exercising the option before its natural expiration date. This premium arises from the flexibility to capitalize on favorable market conditions, particularly when significant dividends are anticipated or volatility is expected to increase. Quantitatively, it’s the difference between the American option’s price and its corresponding European option price, reflecting the cost of that exercise flexibility. Accurate calculation necessitates robust option pricing models, often incorporating binomial trees or finite difference methods, to account for the continuous exercise possibility.
