When I speak to beginners about investing, one common misconception, is that you can invest in the FTSE100 or S&P500, many people fail to understand that these are collections of individual stocks. However, with the rise of Exchange Traded Funds, it is now much easier to invest in the indices through these innovative assets, but it hasn’t always been the case. The FTSE 100 and the S&P 500 are now two of the most frequently used indices when discussing investing, they are important for signalling the strength of UK, US and the wider international economy!
Both indices track the success of a group of companies, but there are some significant distinctions between the two that every investor should be aware of. This comprehensive guide will help you understand the key differences between the FTSE 100 and the S&P 500, their composition, historical performance, and how to invest in them.
Understanding Stock Market Indices
Stock market indices are essential tools in the world of finance, providing investors with valuable information about the performance and health of financial markets. They serve as a representation of a specific segment of the stock market, offering a snapshot of the overall market’s status. By measuring and comparing current stock price levels with historical data, investors can evaluate market performance and make more informed decisions. Perhaps the most well-known stock market in the world is the S&P 500, which primarily tracks US stocks, and in the UK, a comparative index is the FTSE 100, containing large international companies, but while the S&P 500 has 500 companies, the FTSE 100 has 100!
One of the key aspects of stock market indices is their transparency and how easy it now is to invest via exchange-traded funds. They are created based on well-defined methods, ensuring that investors can easily understand the construction and composition of the index. This transparency enables investors to invest in the stock market index through index funds, which can be structured as either mutual funds or exchange-traded funds. These funds aim to track the performance of the index, with any differences between the index and the fund’s performance referred to as tracking error.
Indices can be classified based on their weighting methods, which dictate how stocks are allocated within the index. Regardless of the specific stocks covered, the weighting methodology plays a crucial role in determining the index’s overall performance. Some common index weighting methods include market-capitalisation weighting and equal weight indexing.
Market-capitalisation weighted indices allocate stocks based on their market capitalisation, which is calculated by multiplying a stock’s price by its outstanding shares. This approach results in an index that can be thought of as liquidity-weighted, as larger-cap stocks generally have higher liquidity and can accommodate more significant investor flows. Under the capital asset pricing model, market-cap weighted indices offer mean-variance efficiency, generating the highest return for a given level of risk.
Why are stock indices so attractive for investors?
In the dynamic world of financial markets, one of the key features of stock market indices is their adaptability to reflect the changing landscape of businesses and their performance. By incorporating a mechanism that allows companies to enter or exit the index based on their performance, these indices provide investors with a continually updated and relevant snapshot of the market.
Companies’ inclusion or exclusion from an index is typically governed by predefined rules and criteria, which may encompass factors such as market capitalisation, liquidity, or sector representation. These rules ensure that the index remains a reliable and accurate representation of the market segment it targets, with the most relevant and influential companies forming its constituents.
The process of companies dropping out and entering the index based on their performance offers several benefits for investors. First, it ensures that the index remains up-to-date and accurately reflects the current state of the market. As businesses evolve, some may decline in significance, while others may rise to prominence. By regularly reviewing and adjusting the index’s constituents, the index remains a relevant and useful tool for investors seeking to gauge market performance.
Second, this process helps maintain the index’s diversification by preventing a single company or a small group of companies from dominating the index. As companies grow or shrink in market capitalisation or performance, the index’s composition adjusts accordingly, maintaining a balanced representation of the market segment. Having said that the S&P 500 is made up by a significant component of technology stocks, like Amazon, Apple and Microsoft. The FTSE 100 has historically been heavily influenced by the financial sector (*link to a page in the website*). Finally, the constant updating of the index’s constituents encourages companies to strive for better performance, as gaining or retaining a position within a prestigious index can be seen as a mark of success and credibility. This healthy competition can drive innovation and growth within the market, ultimately benefiting investors and the broader economy. Origins and Purpose of the FTSE 100 and S&P 500
Origins and Purpose of the FTSE 100 and S&P 500
The FTSE 100 and S&P 500 are two of the most widely recognised and influential stock market indices across the world, but first and foremost, the serve as important barometers for the financial markets in the United Kingdom and the United States, respectively.
The S&P 500, launched on March 4, 1957, by Standard & Poor’s (*link to Standard and Poors*), has evolved into a significant measure of the overall health of the U.S. stock market. By tracking the performance of the 500 largest publicly traded companies in the United States, the S&P 500 offers a comprehensive snapshot of the American market. As a result, this index has become a key benchmark for investors seeking to gauge the performance of U.S. equities and to make informed investment decisions. Historically, the returns have been stable, falling in periods of crisis, but quickly rebounding.
Similarly, the FTSE 100, introduced on January 3, 1984, by the Financial Times (**) and the London Stock Exchange, has become an essential indicator of the United Kingdom’s stock market health. Encompassing the 100 largest companies listed on the London Stock Exchange, the FTSE 100 provides a broad representation of the UK’s most influential corporations across various industries. Consequently, this index is widely regarded as a reliable benchmark for the performance of UK equities and an important reference point for both domestic and international investors.
Key Differences Between FTSE 100 and S&P 500
The FTSE 100 and S&P 500 are renowned stock market indices that offer investors insights into the financial markets in the United Kingdom and the United States, respectively. While both indices serve as critical benchmarks for investment performance, they differ in several aspects, including the number of companies they represent, the sectors they focus on, and their geographical concentration.
Firstly, the FTSE 100 comprises the top 100 publicly traded companies listed on the London Stock Exchange, reflecting the performance of the UK’s most influential corporations across various industries. In contrast, the S&P 500 tracks the performance of the 500 largest publicly traded companies in the United States, offering a comprehensive view of the American market.
Secondly, the sectors represented in the two indices differ in their composition. The FTSE 100 features a more diverse range of sectors, including financial services, mining, pharmaceuticals, retail, telecommunications, and utilities, among others. The S&P 500, on the other hand, has a more pronounced focus on technology, with companies like Apple, Microsoft, Amazon, and Alphabet (Google’s parent company) making up a significant portion of the index.
Lastly, the geographical concentration of the indices is distinct. The FTSE 100 primarily represents the UK market (but does contain US companies), with companies such as AstraZeneca, BP, HSBC, and Unilever being key constituents. However, many FTSE 100 companies also have substantial international operations, which can influence the index’s performance. In comparison, the S&P 500 is heavily concentrated in the U.S. market, with American corporate giants like Apple, Microsoft, Amazon, and Alphabet dominating the index.
Composition and Sector Weightings
Examining the top 10 companies in each index and their respective sector weightings sheds light on the market dynamics and offers crucial insights for investors.

Sector Weightings: Shaping the Indices
Sector weightings play a pivotal role in determining the performance of the FTSE 100 and S&P 500. While the FTSE 100 has a higher exposure to financials, energy, and consumer goods, the S&P 500 is more influenced by technology, healthcare, and consumer services. These differences in sector weightings lead to variations in index performances, as sectors react differently to economic conditions and global events.
Implications for Investors
Understanding the composition and sector weightings of the FTSE 100 and S&P 500 is essential for investors seeking to diversify their portfolios and mitigate risk. By investing in ETFs tracking these indices, investors gain exposure to a wide array of companies and industries, reducing the impact of individual stock volatility.
However, it is crucial for investors to be aware of the sector biases within each index. For instance, the FTSE 100’s heavy reliance on financials and energy may expose investors to risks associated with economic downturns or fluctuations in oil prices. On the other hand, the S&P 500’s technology-centric composition may be susceptible to regulatory changes, market competition, and rapid innovation cycles.
By considering these factors, investors can make informed decisions when allocating their assets across different indices, sectors, and geographies. Ultimately, a well-balanced and diversified portfolio is key to achieving long-term financial goals and mitigating risks in the ever-evolving investment landscape.
Historical Performance Comparison: FTSE 100 vs. S&P 500
Over the years, the FTSE 100 and the S&P 500 have been affected by various events and trends, resulting in differing performances. Analysing their historical performance over the past 10, 20, and 30 years provides valuable insights into how these indices have evolved.
Over the past decade, the S&P 500 has significantly outperformed the FTSE 100, primarily driven by the technology sector. Major companies like Apple, Amazon, and Alphabet have experienced tremendous growth, leading to impressive gains in the S&P 500. On the other hand, the FTSE 100 has seen relatively modest growth due to its heavier weighting in financials, energy, and consumer goods, which were affected by slow economic growth and fluctuations in oil prices.
Looking back over the past 20 years, the S&P 500 has again outpaced the FTSE 100. Key events influencing the indices during this period include the dot-com bubble (2000-2002) and the global financial crisis (2007-2009). The dot-com bubble had a greater impact on the technology-heavy S&P 500, while the financial crisis affected the financial sector, causing a significant decline in the FTSE 100. However, the S&P 500 managed to recover faster due to the rapid growth of technology and e-commerce companies.
Over the past 30 years, both indices have experienced growth, but the S&P 500 has again outperformed the FTSE 100. The early 1990s saw the growth of technology companies in the U.S., which contributed to the strong performance of the S&P 500. The FTSE 100, on the other hand, was influenced by events like the UK’s exit from the European Exchange Rate Mechanism (1992) and the late 1990s’ Asian financial crisis, leading to slower growth compared to the S&P 500.
The historical performance comparison of the FTSE 100 and the S&P 500 demonstrates that the S&P 500 has outperformed the FTSE 100 over the past 10, 20, and 30 years. While both indices have been affected by significant events and trends, the S&P 500 has benefited from the rapid growth of the technology sector, which has been a driving force behind its strong performance. In contrast, the FTSE 100 has seen slower growth due to its heavier weighting in financials, energy, and consumer goods, which have been more susceptible to economic downturns and fluctuations in oil prices.
How to Invest in the Indices
There are several ways to invest in the FTSE 100 and the S&P 500, including mutual funds, ETFs, and individual stocks. Each method has its benefits and drawbacks, depending on your investment goals and risk tolerance.
Mutual funds pool money from multiple investors to purchase a diversified portfolio of stocks or other securities. They provide access to professionally managed portfolios and can be a convenient way to invest in the FTSE 100 or S&P 500. However, mutual funds often have higher fees and are typically less tax-efficient compared to ETFs.
ETFs (Exchange-Traded Funds)
ETFs are investment funds that trade like stocks on stock exchanges. They typically track a specific index, such as the FTSE 100 or S&P 500 and offer investors an easy way to gain exposure to these indices.

Investing in individual stocks allows you to build a customized portfolio of companies from the FTSE 100 or S&P 500.

Risks and Rewards of Investing in FTSE 100 and S&P 500
Investing in the FTSE 100 and S&P 500 indices offers potential rewards as well as risks for investors. It is essential to understand these factors before making any investment decisions, in particular, investors need to think carefully about the horizon, that is when they are going to need to take the money they are investing out of the financial markets. It is particularly risky to invest if you have a set end date, that you would like to return the money, i.e. you need this money back in 3 years for example. Please note that investing in stock indices can be risky, especially in the short run, as market fluctuations can lead to potential losses.
Risks of investing in FTSE 100 and S&P 500:
- Currency risk: For investors outside the UK or the US, changes in currency exchange rates can impact the value of their investments. If the investor’s local currency appreciates against the GBP or USD, the investment returns may decrease.
- Economic conditions: Both the FTSE 100 and the S&P 500 are sensitive to economic conditions in their respective countries and globally. Factors such as recessions, changes in interest rates, inflation, and political instability can affect the performance of the indices.
- Sector performance: Since the indices are composed of companies from various sectors, their performance can be impacted by industry-specific risks. For instance, a downturn in the technology sector may negatively affect the S&P 500, which has a higher weighting in technology stocks.
- Diversification: Although the indices consist of many companies, they may not be sufficiently diversified across regions or industries, potentially exposing investors to concentrated risks.
Rewards of investing in the FTSE 100 and S&P 500:
- Capital appreciation: Investing in stock indices like the FTSE 100 and S&P 500 offers the potential for long-term capital appreciation as the constituent companies grow and increase in value. These can really help retirement savings etc.

- Diversification: Despite the risks mentioned earlier, investing in the FTSE 100 and S&P 500 can still contribute to diversification within an investment portfolio, as they provide exposure to different companies and sectors.
Mitigating risks when investing in the FTSE 100 and S&P 500:
Proper asset allocation: Investors can manage risks by allocating their assets across various investment types, industries, and geographic regions. This diversification can help reduce the impact of any single risk factor on the overall portfolio.
Investment strategies: Investors can employ various strategies, such as dollar-cost averaging, to mitigate risks. By regularly investing a fixed amount regardless of market conditions, investors can avoid trying to time the market and potentially reduce the impact of short-term market fluctuations.
Long-term perspective: Adopting a long-term investment perspective can help investors ride out short-term market volatility. While short-term returns can be unpredictable and risky, historical data suggests that stock market investments tend to generate positive returns over longer periods.
Remember, investing in stock indices like the FTSE 100 and S&P 500 carries risks, and returns are not guaranteed, especially in the short term. It is crucial to assess your investment goals, risk tolerance, and investment horizon before deciding to invest in these indices.
