BASICS

Mauro Correro

The stock market is a marketplace where investors buy and sell shares of publicly traded companies.

How Does the Stock Market Work?

To understand how the stock market operates, it’s essential to know the key components involved:

1. Stock Exchanges

Stock markets function through exchanges—platforms where financial instruments such as stocks, ETFs, and derivatives are traded.

Examples: New York Stock Exchange (NYSE), NASDAQ, London Stock Exchange (LSE)
Exchanges can be regulated or unregulated, depending on the jurisdiction and type of instruments traded.
The stock market is not just a place to trade it’s a system of interconnected players and rules designed to allow investors to participate in the economy. Understanding how it works helps demystify investing and empowers individuals to make smarter financial decisions.

2. Brokers

Accessing the stock market as an individual investor requires going through a broker.

A broker is a financial firm that acts as an intermediary, providing tools and platforms to facilitate trades.
Modern brokers often offer all-in-one digital solutions, including portfolio management, research tools, and real-time pricing.
Keep in mind that the first step of a good investment is to have the overall costs clear, because they affect final results.

3. Market Makers

Market makers are institutions or firms that ensure liquidity in the market by continuously buying and selling assets.

They quote both buy (bid) and sell (ask) prices to maintain trading flow.
Their role is essential for minimizing price volatility and ensuring efficient trade execution.

4. Regulators

All activity in the stock market is overseen by regulatory authorities that ensure fairness, transparency, and investor protection.

for example:

SEC (U.S. Securities and Exchange Commission)

ESMA (European Securities and Markets Authority)

FCA (Financial Conduct Authority – UK)

These regulators define rules for public companies, brokers, exchanges, and traders to maintain a level playing field.
