Exercise and Assignment Risk
Exercise and Assignment Risk refers to the possibility that an option contract will be exercised by the holder, requiring the writer to fulfill their obligation. In the context of American-style options, this can happen at any time, while European-style options are exercised only at expiration.
For the writer, assignment means they must buy or sell the underlying asset at the strike price, which can significantly alter their portfolio delta and risk profile. Managing this risk involves monitoring the option's moneyness and the cost of carry.
It is a critical component of risk management for anyone selling options, especially in volatile crypto markets where exercise might occur unexpectedly. Failure to prepare for assignment can lead to forced liquidations or unwanted directional exposure.
