A stock (or share) represents a small ownership stake in a single company. Buy one, and you legally own a fraction of that business. Its price moves with the company's performance and overall market demand, and depending on the company, shareholders may also receive dividends or voting rights.
For example, if a company divides itself into a million shares and you own one, you hold a one-millionth stake in that business, including a claim on its future profits and, often, a vote at shareholder meetings.
Companies issue shares to raise money for growth.
Shares are bought and sold on stock exchanges.
