Are you planning to invest in the London Stock Exchange (LSE)?

But confused about where to start?

Well, don’t worry, it is quite normal. The London Stock Exchange might sound too confusing at first. Words like stocks, shares, indices, and trading are new to many of us. However, once you become familiar with it, it will become simpler.

So, in this guide, I will walk you through all the key terms to help simplify the world of the stock exchange for you. In the end, you will know what LSE is, how it works, why it is important, and how to start investing. Let us get started!

What is London Stock Exchange (LSE)?

The London Stock Exchange is one of the most important, famous, and oldest stock exchanges in the world. It comprises thousands of companies from over 60 countries, with a market capitalization exceeding £ 4.5 trillion  in 2025.

It is like a marketplace for stocks, where you can buy and sell stocks of companies. And these stocks represent the ownership in a company.

So, when you buy a share of a company from the London Stock Exchange, you become a small part-owner of that firm. Thus, when the company performs well, the price of shares goes up, giving you a profit. And when it performs badly, you can incur a loss too.

It is that simple.

LSE is based in London, UK. And it plays a crucial role in the financial market worldwide.  

A Brief History Overview of LSE

Let us take a quick sneak peek into the history of the London Stock Exchange.

Well, the history of LSE dates back over 300 years. It all started in 1698 at Jonathan’s Coffee Shop. But officially, a more formal club was opened with the name of “New Jonathan’s” or “The Stock Exchange” at Sweeting’s Alley.

In 1802, they shifted to a neat building for proper trading channels. With time, they grew into a trusted and regulated body for the financial market.

Today, it is considered one of the best international stock markets in the world, with thousands of companies listed from all over the world.

How Does the London Stock Exchange Work?

You must be wondering how this huge marketplace actually operates. And this is an important question if you really want to invest in LSE.

It might feel complicated, but it is simpler than you think. Let me explain it briefly to you:

1. Companies list their shares on the London Stock Exchange
2. People who want to invest, buy, or sell these shares
3. The prices keep changing depending on the supply and demand
4. Every single transaction or trade is done digitally

So, when more people are willing to buy a particular share, the prices go up. But when people want to sell, the prices go down. This is how it works.

This whole process of buying and selling shares is called Stock Market Trading.

Why Do Companies List on the London Stock Exchange?

Another key question.

Well, there might be many reasons for a company to list its shares on the Stock Exchange. Here are some of them:

• Raise money for growth or expansion
• To obtain trust and credibility in the market
• For attracting investors locally and internationally
• To increase awareness among the public

Hence, when a company offers its first shares to the public, this process is called the Initial Public Offering (IPO).

Key Markets in the London Stock Exchange

Now, let us talk about the key markets that exist in the London Stock Exchange.

Yeah, two small markets in this marketplace are created to suit various kinds of organizations. They include:

• Main Market

It is for the big and well-established firms. They are required to meet strict financial and regulatory requirements to stay in this group.

• AIM (Alternative Investment Market)

This one is designed for developing companies. It has more flexible rules and policies. Hence, it is quite popular among startups and growing businesses.

Both of these markets provide a chance for investors to invest according to their risk appetite.
