Definition of 'Common Stock'

A security that represents ownership in a  corporation. Holders of common stock exercise control by electing a board of  directors and voting on corporate policy. Common stockholders are on the bottom  of the priority ladder for ownership structure. In the event of liquidation,  common shareholders have rights to a company's assets only after bondholders,  preferred shareholders and other debtholders have been paid in full.
In  the U.K., these are called "ordinary shares."
