BusinessLesson on requestFree to read

Quick answer

A stock exchange works as a marketplace where people buy and sell shares of companies. It matches buyers with sellers, sets prices through supply and demand, and lets companies raise money while giving investors a way to own a piece of a business.

Step by step

  1. It's an organized market for trading company shares.
  2. Buyers and sellers place orders, and the exchange matches them.
  3. Prices rise and fall with supply and demand.
  4. Companies list shares to raise money from investors.
  5. Examples include the NYSE, Nasdaq, and the BSE.
