Quick Definition

The act of exercising an American-style option before its expiration date, typically done only when specific conditions make it financially advantageous.

What Is Early Exercise?

Early exercise occurs when the holder of an American-style option exercises the contract before the expiration date. While always available as a right, early exercise is rarely optimal because it forfeits the remaining time value of the option. There are two primary scenarios where early exercise makes sense: (1) deep in-the-money call options on stocks about to pay a dividend — exercising captures the dividend that would otherwise be lost, and (2) deep in-the-money put options where the intrinsic value significantly exceeds the time value, and the proceeds could earn meaningful interest. For non-dividend-paying stocks, it is never optimal to early-exercise a call option. Understanding early exercise is crucial for option sellers who face assignment risk, particularly around ex-dividend dates.

Early Exercise Example

  • 1A trader holds an AAPL $100 call when the stock is at $180 and a $1.50 dividend is due tomorrow. Early exercise captures the dividend, which exceeds the remaining time value of $0.80
  • 2A deep in-the-money $200 put on a stock trading at $50 has $150 intrinsic value but only $0.10 time value — early exercise frees up $5,000 per contract to earn interest
