How shares represent fractional ownership in a corporation, giving holders residual claims on profits and voting rights.

What is a stock?

A stock (also called a share or equity) represents fractional ownership in a corporation. When you own a share of a company, you legally own a proportional piece of that company's assets and future earnings.

How do stockholders make money?

Investors make money from holding stocks through two distinct paths:

  • Dividends — Regular cash distributions paid to shareholders when a profitable company decides to share a portion of its net earnings rather than reinvesting all of it back into operations.
  • Capital appreciation — Selling the share for a higher price than what you paid for it. If a company invents popular products, grows revenues, and expands its profit margins, other investors will value its shares more highly, driving up the stock price.

Limited liability and residual claims

Two legal concepts make corporate stock powerful:

  • Limited liability — As a shareholder, your financial loss is strictly limited to the amount you invested. If the corporation goes bankrupt or gets sued, creditors cannot seize your personal home, car, or bank savings.
  • Residual claim — Stockholders stand last in line. If a company liquidates, bondholders, suppliers, employees, and tax authorities must be fully paid before shareholders receive any remaining assets. In exchange for taking that risk, shareholders enjoy unlimited upside when the company thrives.

Primary versus secondary markets

When a company first sells shares to the public to raise capital for factories or research, it does so in the primary market through an Initial Public Offering (IPO).

After that initial sale, those shares trade continuously between investors on the secondary market (the stock exchange). In secondary trading, money flows between investors, not to the company itself.
