EARLY ASSIGNMENT ON CREDIT SPREADS
After a credit spread on equities is executed, is there a risk of early assignment on the short leg if extrinsic value goes below $0.20? Before execution, if the short leg of a credit spread has an extrinsic value of $0.20 or less, will it ever be executed? I know there is no early assignment on calls/puts on European-style indexes.
Iíd appreciate your advice. óPaul
You are correct that options with the European-style settlement feature do not carry any early-assignment risk because exercise and assignment can only happen at expiration. Most (but not all) index options settle European-style and can only be exercised at expiration.
Stock options settle American-style and, as a result, exercise and assignment can happen any time prior to expiration. But it isnít likely that an option with time value will be exercised, because the option owner would lose or sacrifice that time value if they exercise the contract.
They would be leaving money on the table. When time value remains, it is usually better to sell the option to close the position rather than exercise it.
