What Is the Stock Market? A Beginner-Friendly Guide

The stocks market is a place where people buy and sell ownership shares of publicly traded companies. When you invest in the stock market, you are investing in real businesses—companies that produce goods, provide services, and drive the US economy.

In the United States, the stock market plays a crucial role in wealth creation, retirement planning, and economic growth. Millions of Americans participate in the stock market through brokerage accounts, 401(k) plans, and mutual funds.

How the Stock Market Works

At its core, the stock market connects companies that need money with investors who want to grow their wealth.

Step-by-step overview:

1. A company decides to raise capital.
2. It offers shares to the public through an Initial Public Offering (IPO).
3. Investors buy these shares.
4. After the IPO, shares trade freely between investors on stock exchanges.

Once shares are listed, the company does not receive money from day-to-day trading. Instead, investors trade shares with each other.
