The Financial Times Stock Exchange 100, or FTSE 100, is a financial index composed of the 100 most highly capitalized companies listed on the London Stock Exchange. It is considered to be one of the most accurate measures for understanding the overall health of British and international markets. In this blog, we will be examining how market capitalization has contributed to which companies are currently included in the FTSE 100 and explore both its benefits and drawbacks.
What is the FTSE 100 and How is It Determined?
The FTSE 100, also known as the Financial Times Stock Exchange 100 Index, is a stock market index comprising the top 100 most highly capitalized companies listed on the London Stock Exchange. This index serves to provide an accurate measure of both British and international markets by tracking their performance through changes in share price.
The FTSE 100 is calculated using a methodology that takes into account several factors such as market capitalization, liquidity, and turnover when selecting which companies are included in this index.
Market capitalization refers to the total value of all outstanding shares for each company within the index and takes precedence over other criteria when determining inclusion. As such, larger firms with higher values will be more likely to make it onto the list than smaller businesses due to their greater impact on overall market movements.
How Market Capitalization Influenced the Companies That are Included in The FTSE 100?
Market capitalization has been an influential factor in determining which companies make up the FTSE. The index is composed of the most highly capitalized businesses listed on the London Stock Exchange and as such, it rewards those firms with larger market values over smaller ones.
This means that more established and larger firms are likely to be included than newer or smaller ones due to their greater impact on overall market movements.
By relying heavily upon this measure, it allows for more accurate measurement of both British and international markets by tracking their performance through changes in share price. Furthermore, this approach ensures that only reliable investments are promoted within the index by upholding high standards for inclusion criteria and excluding any underperforming stocks from consideration.

The Benefits
Being included in the FTSE 100 provides numerous benefits for companies. Firstly, it grants them a higher level of visibility and recognition within financial circles as investors tend to pay close attention to the movements of this index. This can help boost investor confidence and attract additional capital into these businesses, allowing them to grow further while increasing their market share.
Additionally, inclusion in the FTSE 100 also offers firms increased liquidity due to increased trading volume driven by interest from investors who are tracking the performance of the index.
Moreover, many institutional investors prefer investing in stocks that make up this index as they provide a safer option and greater stability compared with other investments. Ultimately, being listed on the FTSE 100 is beneficial for firms looking to establish themselves as leaders within their field and create long-term value for shareholders over time.
Drawbacks
Despite the numerous benefits of being included in the FTSE 100, there are also some drawbacks to consider. Firstly, larger firms with more established brands and greater market capitalization tend to dominate this index due to its reliance on the market size as a criterion for inclusion.
This can be disadvantageous for smaller companies who may have strong business fundamentals but lack the resources or financial base required to become part of this index.
Being included in the FTSE 100 does not guarantee performance and stock prices can still fall even when a company is listed on this index due to external factors such as market sentiment or macroeconomic conditions.
Finally, it can be difficult for new entrants into the market or companies that are currently outside of this index to compete with those already established within it due to their higher levels of exposure and recognition amongst investors.
What does the future hold for the FTSE 100?
The FTSE 100 has established itself as one of the premier stock indices in the world and its future looks bright. As the UK economy continues to recover from the effects of COVID-19, it is likely that this index will remain an important benchmark for investors looking to gain exposure to British markets.
Furthermore, with companies continuing to innovate and develop new products or services, there may be an influx of fresh entrants into this index which could further strengthen its position within global financial circles.
The increased investor confidence should drive more capital into these stocks as they seek out attractive returns while also helping boost overall trading volumes. All in all, the future looks promising for the FTSE 100 as it remains a reliable source of tracking performance across both domestic and international markets over time.
In Conclusion
The FTSE 100 has seen fluctuations over its long history, but it continues to provide a benchmark for investors. Market capitalization has had an undeniable effect on what companies are included in the FTSE 100 and, by proxy, its success.
The benefits of being included in this exclusive cohort are apparent given its continued popularity amongst financiers but we must bear in mind that there have been drawbacks for certain companies as well. Despite this ambiguity, the future of the FTSE 100 remains bright and may even become more influential as market landscapes continually change.
