FTSE 100 Index: Overview, Key Stocks, and Trading Guide

This article will introduce the characteristics and usage of the FTSE 100 Index in the UK for reference by traders.
What is the FTSE 100 Index?
The FTSE 100 Index (UK100) was created on January 3, 1984, by the Financial Times and the London Stock Exchange. It is a stock market index composed of the stock prices of the 100 largest companies listed on the London Stock Exchange. Most of these companies are large-cap blue-chip stocks, making the FTSE 100 Index one of the main indicators of the UK stock market.
The FTSE 100 Index is a market capitalization-weighted index, meaning the larger the market capitalization of a company, the greater its weight in the index. As a result, stock price movements of some large companies have a more significant impact on the index. The index is adjusted quarterly to ensure that its constituent stocks continue to represent the largest companies by market cap. If a company’s market cap decreases or if a new company’s market cap grows rapidly, it may be added or removed from the index.
What are the Constituent Stocks of the FTSE 100 Index?
The FTSE 100 Index consists of the 100 largest companies by market cap, spanning various sectors, including finance, energy, consumer goods, healthcare, industrials, materials, telecommunications, and technology.
Here are some of the key constituent companies and their respective sectors:
| Sector | Key Companies |
|---|---|
| Finance | HSBC Holdings, Barclays, Lloyds Banking Group, Prudential |
| Energy | BP, Royal Dutch Shell, SSE |
| Consumer Goods | Unilever, Diageo, British American Tobacco |
| Healthcare | GlaxoSmithKline, AstraZeneca, Smith & Nephew |
| Industrials | Rolls-Royce Holdings, BAE Systems, Intertek Group |
| Materials | Rio Tinto, BHP, Anglo American |
| Telecommunications | BT Group, Vodafone Group |
| Technology | Sage Group, Ocado Group |
These companies not only have significant influence in the UK but also play a major role in global markets. The FTSE 100 Index is adjusted regularly to ensure that it represents the 100 largest companies by market cap, so the list of constituent stocks may be updated in response to market changes.
In addition, the FTSE 100 Index undergoes quarterly reviews and adjustments to ensure that its constituent stocks continue to represent the largest 100 companies. These adjustments help the index accurately reflect market changes and the performance of large companies' stock prices.
Recent Performance of the FTSE 100 Index

The performance of the FTSE 100 Index (UK100) in recent years has been influenced by various factors, including global economic conditions, political events, the Brexit process, the COVID-19 pandemic, and more.
Here are some key performance highlights of the FTSE 100 Index in recent years:
2016
In June 2016, the results of the UK’s Brexit referendum caused significant market volatility, and the FTSE 100 Index dropped sharply in the short term. However, the index gradually recovered due to the depreciation of the British pound and the global market’s recovery, reaching higher levels by the end of the year.
2017
In 2017, global economic recovery and corporate profit growth contributed to an upward trend in the FTSE 100 Index. By the end of the year, the index reached a historical high, breaking 7700 points.
2018
In 2018, the FTSE 100 Index saw greater volatility due to factors such as global trade tensions and the U.S. interest rate hike policy. Although the index continued an upward trend in the early part of the year, it experienced several pullbacks in the second half, resulting in a relatively flat performance for the year.
2019
In 2019, the uncertainty surrounding Brexit continued to impact the market. However, with the Conservative Party’s victory in the general election and a clearer Brexit process, the FTSE 100 Index rebounded significantly in the fourth quarter.
2020
In 2020, the outbreak of the COVID-19 pandemic caused a severe shock to global markets. In March, the FTSE 100 Index fell sharply, dipping below 5000 points. However, as governments and central banks implemented large-scale economic stimulus policies, the market gradually recovered, and the FTSE 100 Index rebounded in the second half of the year.
2021
In 2021, with the widespread distribution of vaccines and economic recovery, the FTSE 100 Index performed well overall. While there were some fluctuations during the year, the index ended the year near 7500 points.
2022
In 2022, the FTSE 100 Index faced significant pressure due to rising inflation, soaring energy prices, and geopolitical tensions (such as the Russia-Ukraine conflict). Despite this, the index showed resilience, with significant volatility throughout the year, but it remained above 7000 points.
2023
In 2023, the global economy continued to face challenges, including supply chain issues, persistent inflationary pressures, and central bank interest rate hikes. The FTSE 100 Index performed relatively steadily during the year, though it was still affected by these factors.
Overall, the performance of the FTSE 100 Index has been influenced by global economic conditions, political events, and domestic economic policies in the UK. Investors need to closely monitor these factors to better understand and forecast the future movements of the index.
