What Are Stocks? A Beginner’s Guide to Investing in the Stock Market

📌 Introduction

You’ve probably heard that investing in stocks can make you rich — or that it’s risky and only for experts. The truth lies in between: stocks are a powerful tool to build long-term wealth, but they require knowledge and strategy.

In this Dicas de Bolso guide, you’ll learn:

  • What stocks are

  • How they work

  • The risks and benefits involved

  • How to start investing safely

  • Practical tips for beginners


💡 What Are Stocks?

Stocks represent small ownership slices of a company. When you buy a stock, you become a shareholder — even if it’s just a tiny part.

That means if you buy shares of Petrobras, Itaú, or Magazine Luiza, you actually own a piece of those companies. Depending on the stock type, you may also have voting rights and receive part of the company’s profits.


⚙️ How Do Stocks Work?

1. Traded on the Stock Exchange

Stocks are bought and sold on B3 (the Brazilian Stock Exchange) via a brokerage. Prices change constantly based on supply and demand.

2. Price Appreciation

As a company grows, innovates, or earns more profit, its shares tend to increase in value. You can sell them later at a higher price to earn capital gains.

3. Dividends

Some companies share part of their profits with shareholders in the form of dividends — a great way to earn passive income from stocks.


🧭 Types of Stocks

📃 Common Stocks (ON)

Give voting rights in shareholder meetings.
Example: PETR3 (Petrobras ON)

💰 Preferred Stocks (PN)

Priority in receiving dividends, but usually no voting rights.
Example: PETR4 (Petrobras PN)

🛣️ How to Start Investing in Stocks?
