Explanation:

A stock represents ownership of a company. The total value of an organization is subdivided into small units called stock, shares, or equity. Each stock or share is a small portion of the organization. Holders or owners of the shares are the owners of the company. They are known as shareholders or stockholders.

Shareholders acquire their shares or equity by either being the founders of the business or by purchasing them. When a business is being formed, the founders contribute capital, which converts to shares. The business may opt to sell more shares to the public through IPO when they need to raise additional capital.
