Options Chain

An options chain (or option matrix) is a listing of all available option contracts for a given security, organized by expiration date and strike price. It displays current bid, ask, volume, open interest, and implied volatility for each contract.

The options chain is the complete menu of available contracts for a stock — where the money is concentrated, how expensive different strikes are, and what expirations traders are focused on. It is defined here because you will meet it constantly in options material.
