American Option
An option style that lets the holder exercise at any time before expiration, unlike a European option.
Exercise-style option terms for American, Bermuda, European, vanilla, LEAPS, and low-exercise-price options.
Standard Exercise Style Options is the financial-instruments landing page for option rights, holders, writers, calls, exercise prices, expiration dates, moneyness, contract styles, listed options, option classes, chains, underlyings, warrants, and real options. It keeps related terms in one branch so readers can move from a broad instrument question to the article that owns the contract evidence.
Use this page when an option contract term changes rights, obligations, exercise timing, moneyness, or underlying exposure. Use the parent Standard Option Styles and Listed Contracts page when you need the broader instrument map. For an individual decision, confirm the contract, term sheet, prospectus, confirmation, exchange specification, or disclosure record before relying on the term.
