How US Stock Market Works: A Comprehensive Guide

Understanding the Basics

The US stock market is one of the most dynamic and influential financial markets in the world. It's a place where investors buy and sell shares of publicly-traded companies, allowing them to own a portion of the company. If you're new to the stock market or looking to deepen your understanding, this guide will help you navigate the intricacies of how the US stock market works.

What is the Stock Market?

The stock market is a marketplace where shares of publicly-traded companies are bought and sold. These shares represent ownership in the company and are divided into units called "stocks." When you buy a stock, you are essentially purchasing a small piece of that company.

Primary and Secondary Markets

The stock market operates through two main markets: the primary market and the secondary market.

  • Primary Market: This is where companies issue new shares to the public for the first time. This process is known as an Initial Public Offering (IPO). Investors can purchase these shares directly from the company.
  • Secondary Market: This is where existing shares are bought and sold among investors. The New York Stock Exchange (NYSE) and the Nasdaq are the most prominent secondary markets in the United States.

How Stocks are Traded

Stocks are traded through exchanges, which are organizations that facilitate the buying and selling of stocks. The most well-known exchanges in the US are the NYSE, Nasdaq, and the American Stock Exchange (AMEX).

When you want to buy or sell a stock, you place an order through a brokerage firm. The brokerage firm then executes the order on your behalf, either by buying the stock from another investor or selling it to another investor.

Understanding Stock Quotes

A stock quote provides essential information about a stock, including its current price, trading volume, and market capitalization. Here's what you need to know:

  • Price: The current price of the stock per share.
  • Trading Volume: The number of shares traded in a given period.
  • Market Capitalization: The total value of a company's outstanding shares, calculated by multiplying the number of shares by the stock's price.

Key Players in the Stock Market

Several key players participate in the stock market:

  • Investors: Individuals, institutional investors, and mutual funds that buy and sell stocks.
  • Brokers: Individuals or firms that execute orders for investors.
  • Market Makers: Financial institutions that provide liquidity to the market by buying and selling stocks.
  • Regulators: Organizations like the Securities and Exchange Commission (SEC) that regulate the stock market to ensure fair and transparent trading.

Case Study: Facebook's IPO

One of the most significant IPOs in recent history was Facebook's in 2012. The company raised 16 billion by selling 421 million shares at 38 per share. The IPO was a massive success, and Facebook became the most valuable company ever to go public.
