## Option Expiration Risk

Option expiration risk is the danger that a position becomes worthless or results in an unexpected obligation at the end of its life. For long option holders, the primary risk is that the option finishes out of the money, leading to the loss of the entire premium paid.

However, there is also the risk of automatic exercise, where an in-the-money option is exercised, requiring the trader to settle the position in the underlying asset or cash. If the trader does not have the necessary capital or assets to fulfill this obligation, it can lead to forced liquidations or margin calls.

Managing this risk involves monitoring the moneyness of the position as the expiration date approaches and deciding whether to sell, exercise, or let the contract expire. Proper planning prevents last-minute surprises in derivative portfolios.
