Stock is ownership in a corporation.
When a business incorporates, owners receive stock to indicate their holdings in the company. Usually, most stockholders only own a small fraction of a company. Because they represent ownership, stocks are often referred to as equities. A stock certificate shows the number of shares held. The certificate may be made out for one share or a number of shares.
