Call
An option right to buy an underlying asset at a specified exercise price before or at expiration.
Basic option-contract terms for option rights, holders, writers, call rights, and options trading activity.
Core Option Contracts and Parties 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 Options Contracts and Exercise Features 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.

Core Contracts content is educational and does not provide personalized investment, tax, legal, accounting, valuation, derivatives, or securities advice.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
