national stock exchange that is located at the corner of Broad and Wall Streets in New York City; often called the Big Board. It has a central trading location where securities are bought and sold in an auction market by brokers acting as agents for the buyer and seller. It is governed by a board of directors consisting of one-half exchange members and one-half public members. The NYSE is the largest exchange and generates the most dollar volume in large, well-known companies. Its listing requirements are the most restrictive. For a company to be listed on the NYSE for the first time, for example, the corporation must have at least 2000 stockholders owning 100 shares, and its aggregate market value must be $18 million or more.
