How Does the Stock Market Work?

At its core, the stock market operates on the principles of supply and demand. When a company goes public, it issues shares of stock, which represent ownership in the company. These shares are then listed on a stock exchange, where investors can buy and sell them.

The price of a stock is determined by the collective actions of buyers and sellers in the market. If more people want to buy a stock than sell it, the price will go up. Conversely, if more people want to sell a stock than buy it, the price will go down.

Types of Stock Markets

There are two main types of stock markets:

  • Primary Market: This is where companies first issue shares to the public through an initial public offering (IPO).
  • Secondary Market: This is where investors buy and sell shares among themselves after the IPO. The major stock exchanges, such as the New York Stock Exchange (NYSE) and the Nasdaq, are part of the secondary market.
