FTSE 100: Explained
BY TIO Staff
|July 12, 2024The FTSE 100, also known as the Financial Times Stock Exchange 100 Index, is a share index of the 100 companies listed on the London Stock Exchange with the highest market capitalization. It is seen as a gauge of prosperity for businesses regulated by UK company law. The index is maintained by the FTSE Group, a subsidiary of the London Stock Exchange Group.
The FTSE 100 is used extensively as a basis for investment products, such as derivatives and exchange-traded funds. In this comprehensive glossary entry, we will delve into the intricacies of the FTSE 100, its history, how it works, its significance in trading, and much more.
History of the FTSE 100
The FTSE 100 was launched on January 3, 1984, with a base level of 1000. The index was developed by the Financial Times and the London Stock Exchange, hence the name FTSE. It was intended to be a comprehensive and reliable measure of the UK stock market's performance.
Over the years, the FTSE 100 has seen numerous changes, with companies entering and exiting based on their market capitalization. The index is reviewed quarterly, and adjustments are made to reflect the changing landscape of the UK economy.
Notable Events in FTSE 100 History
Throughout its history, the FTSE 100 has experienced significant fluctuations due to various economic events. For example, the Black Monday crash in October 1987 caused the index to drop by over 10% in a single day.
More recently, the FTSE 100 experienced significant volatility during the 2008 financial crisis and the 2020 COVID-19 pandemic. These events highlight the sensitivity of the index to global economic conditions.
How the FTSE 100 Works
The FTSE 100 is a capitalization-weighted index, meaning that companies with a larger market capitalization have a greater influence on the index's value. The index is calculated in real-time, with prices updated every 15 seconds during trading hours.
The value of the FTSE 100 is derived from the aggregate market capitalization of its constituent companies, divided by a factor known as the "index divisor". The index divisor is adjusted whenever there are changes in the index constituents, such as when a company is added or removed, to ensure continuity in the index value.
Components of the FTSE 100
The FTSE 100 is made up of 100 of the largest companies listed on the London Stock Exchange. These companies represent a variety of sectors, including finance, energy, consumer goods, and more. The composition of the index is reviewed quarterly by the FTSE Group.
Some of the most prominent companies in the FTSE 100 include HSBC, BP, Unilever, and AstraZeneca. The inclusion in the FTSE 100 is often seen as a mark of prestige for companies, reflecting their status as leaders in their respective industries.
Significance of the FTSE 100 in Trading
The FTSE 100 is a crucial tool for traders and investors alike. It provides a snapshot of the UK's economic health and serves as a benchmark for investment performance. Many investors use the FTSE 100 as a reference point for comparing the performance of individual stocks or funds.
Furthermore, the FTSE 100 is the underlying asset for a range of financial products, including futures, options, and exchange-traded funds. This allows traders to speculate on the overall direction of the UK stock market, rather than focusing on individual stocks.
Trading the FTSE 100
Trading the FTSE 100 can be done in several ways. One common method is through contracts for difference (CFDs), which allow traders to speculate on the index's price movements without owning the underlying shares. This can provide opportunities for both long and short positions.
Another method is through exchange-traded funds (ETFs) that track the FTSE 100. These funds aim to replicate the performance of the index, providing investors with exposure to the UK stock market in a single transaction. ETFs can be bought and sold like individual stocks, offering flexibility for traders.
Factors Influencing the FTSE 100
Several factors can influence the value of the FTSE 100. These include economic indicators, corporate earnings reports, geopolitical events, and changes in monetary policy. Understanding these factors can help traders make informed decisions when trading the FTSE 100.
For example, strong economic data or positive earnings reports can boost investor confidence, leading to an increase in the FTSE 100. Conversely, political uncertainty or disappointing earnings can cause the index to fall.
Impact of Currency Fluctuations
One unique aspect of the FTSE 100 is its sensitivity to currency fluctuations. Many companies in the FTSE 100 generate a significant portion of their revenue overseas. As a result, a weaker pound can boost these companies' earnings when converted back into sterling, potentially lifting the FTSE 100.
Conversely, a stronger pound can have the opposite effect, putting pressure on the FTSE 100. This relationship between the FTSE 100 and the pound is an important consideration for traders.
Conclusion
The FTSE 100 is more than just a number. It's a barometer of the UK economy, a benchmark for investors, and a trading instrument in its own right. Understanding the FTSE 100 can provide valuable insights for traders, whether they're speculating on short-term price movements or investing for the long term.
As with any form of trading, it's important to do your research and understand the risks involved. With the right knowledge and strategy, trading the FTSE 100 can be a rewarding endeavor.
