Rounding out the top five were some of the world’s most recognizable brands: Apple, NVIDIA, Google’s parent company Alphabet, and Amazon. Saudi Aramco led the ranking of the world's most profitable companies in 2023, with a pre-tax income of nearly 250 billion U.S. dollars. How are market value and market capitalization determined? Market value and market capitalization are two terms frequently used – and confused - when discussing the profitability and viability of companies. Strictly speaking, market capitalization (or market cap) is the worth of a company based on the total value of all their shares; an important metric when determining the comparative value of companies for trading opportunities. Accordingly, many stock exchanges such as the New York or London Stock Exchange release market capitalization data on their listed companies. On the other hand, market value technically refers to what a company is worth in a much broader context. It is determined by multiple factors, including profitability, corporate debt, and the market environment as a whole. In this sense it aims to estimate the overall value of a company, with share price only being one element. Market value is therefore useful for determining whether a company’s shares are over- or undervalued, and in arriving at a price if the company is to be sold. Such valuations are generally made on a case-by-case basis though, and not regularly reported. For this reason, market capitalization is often reported as market value. What are the top companies in the world? The answer to this question depends on the metric used. Although the largest company by market capitalization, Microsoft's global revenue did not manage to crack the top 20 companies. Rather, American multinational retailer Walmart was ranked as the largest company in the world by revenue. Walmart also had the highest number of employees in the world.

The Standard & Poor’s (S&P) 500 Index is an index of 500 leading publicly traded companies in the United States. In 2021, the index value closed at 4,766.18 points, which was the second highest value on record despite the economic effects of the global coronavirus (COVID-19) pandemic. In 2023, the index values closed at 4,769.83, the highest value ever recorded. What is the S&P 500? The S&P 500 was established in 1860 and expanded to its present form of 500 stocks in 1957. It tracks the price of stocks on the major stock exchanges in the United States, distilling their performance down to a single number that investors can use as a snapshot of the economy’s performance at a given moment. This snapshot can be explored further. For example, the index can be examined by industry sector, which gives a more detailed illustration of the economy. Other measures Being a stock market index, the S&P 500 only measures equities performance. In addition to other stock market indices, analysts will look to other indicators such as GDP growth, unemployment rates, and projected inflation. Similarly, since these indicators say something about the economic future, stock market investors will use these indicators to speculate on the stocks in the S&P 500.

Enterprise value to earnings before interest, taxes, depreciation and amortization (EV/EBITDA) is a key measurement ratio used as a metric of valuing whether a company is under or overvalued as compared to a historical industry average. The S&P 500 (Standard & Poor’s) is an index of the 500 largest U.S. publicly traded companies by market capitalization. In 2023, the consumer staples sector displayed the highest EV/EBITDA multiple with 15.14.

The Standard & Poor's 500 stock index (S&P 500) is a commonly cited indicator of stock market performance. It is a scaled average of 500 large-capitalization common stocks in the United States. The companies included in the index operate in various sectors across the economy, including energy, finance, telecommunications, retail and manufacturing. The values presented in this report are the December 31 close figures. Data is sourced from the St. Louis Federal Reserve.

Until the fourth quarter of 2023, the S&P 500 and the S&P 500 ESG index exhibited similar performance, both indexes were weighted to similar industries as the S&P 500 followed the leading 500 companies in the United States. Throughout 2024, the S&P 500 ESG index steadily outperformed the S&P 500 by three points on average. During the coronavirus pandemic, the technology sector was one of the best-performing sectors in the market. The major differences between the two indexes were the S&P 500 ESG index was skewed towards firms with higher environmental, social, and governance (ESG) scores and had a higher concentration of technology securities than the S&P 500 index. What is a market capitalization index? Both the S&P 500 and the S&P 500 ESG are market capitalization indexes, meaning the individual components (such as stocks and other securities) weighted to the indexes influence the overall value. Market trends such as inflation, interest rates, and international issues like the coronavirus pandemic and the popularity of ESG among professional investors affect the performance of stocks. When weighted components rise in value this causes an increase in the overall value of the index they are weighted too. What trends are driving index performance? Recent economic and social trends have led to higher levels of ESG integration and maintenance among firms worldwide and higher prioritization from investors to include ESG-focused firms in their investment choices. From a global survey group over one-third of the respondents were willing to prioritize ESG benefits over a higher return on their investment. These trends influenced the performance of securities on the market, leading to an increased value of individual weighted stocks, resulting in an overall increase in the index value.

Equity returns remained high in 2020, in spite of the uncertainty and volatility caused by the coronavirus pandemic and related partial shutdowns. Initial public offerings (IPOs) ended the year with the highest rate of equity returns, which amounted to 76 percent returns for investors. However, the most compelling financial story in the second half of the year revolved around the huge increase in IPOs via special purpose acquisition companies (SPACs). SPAC mergers refer to the practice of a SPAC, which is a publicly listed company with no operations, merging with a private company to take the latter public without following the normal IPO process. In 2021, however, IPOs and SPAC mergers experienced negative returns.

Why are NASDAQ and S&P 500 relevant benchmarks?

The Nasdaq and the S&P 500 are two of the most important stock indices in the United States, if not the world. The Nasdaq Composite Index includes over 2,500 stocks listed on the Nasdaq stock market, which is the second largest stock exchange globally. The S&P 500 index tracks the stock value of 500 large companies, such as Facebook and Alphabet, listed on the New York Stock Exchange.

What level of impact did the pandemic have on these indices?

Over the past decade, both the NASDAQ Composite index and the S&P 500 index have skyrocketed in value. However, both indices took a hit in February and March 2020 when the uncertainty caused by the pandemic led to investors selling off assets en masse. This dip was short-lived and both indices had fully recovered by the third quarter.

As of December 2023, State Street’s SPDR S&P 500 ETF Trust was the highest valued exchange-traded fund (ETF) globally, with a market capitalization of about 417.37 billion U.S. dollars. Market capitalization of an ETF is calculated by multiplying the number of shares issued in the fund by the share price. This ETF is also the largest ETF by assets under management - although, at over 1 trillion U.S. dollars, the Vanguard Total Stock Market Index Fund is overall the largest investment fund by AUM. However, the Vanguard fund is different because shares in the fund are sold as a variety of different products, some of which are structured as ETFs (like the third-largest fund listed in this statistic), while others are structured as traditional mutual funds.

What are ETFs?

ETFs are similar to mutual funds, in that they consist of a pool of investors’ funds which are managed by an independent third party for the purpose of a common financial investment. However, ETFs differ through how shares in the fund are bought and sold through a stock exchange, rather than directly from the fund manager. This provides the advantages of generally lower prices (as the transaction costs are paid by the exchange operator rather than the fund manager), and the possibility of intraday trading (as shares in a traditional mutual fund can only be bought and sold after the close of daily trading. The total assets managed by ETFs globally is almost six times lower than that of mutual funds, although the gap in AUM between ETFs and mutual funds in the United States is much lower, at just over three times less.

Who are the largest ETF providers?

The largest provider of ETFs globally is Blackrock, the world’s largest asset management company. As of 2023, the company had more than 2.3 trillion U.S. dollars of assets under management in exchange traded funds in the U.S. alone, while Blackrock’s total assets under management across all products reached almost ten trillion U.S. dollars. Rounding out the top three providers of ETFs are fellow U.S asset managers Vanguard and State Street.

Coronavirus sparks stock market chaos Stock markets plunged in the wake of the COVID-19 pandemic, with investors fearing its spread would destroy economic growth. Buoyed by figures that suggested cases were leveling off in China, investors were initially optimistic about the virus being contained. However, confidence in the market started to subside as the number of cases increased worldwide. Investors were deterred from buying stocks, and this was reflected in the markets – the values of the Dow Jones Industrial Average and the Nasdaq Composite also dived during the height of the crisis.

However, just over three weeks later, the market closed on 2,480, which represented a decline of around 26 percent in only 16 sessions.

Today, it represents a broader range of high-growth, non-financial companies across sectors like consumer services and healthcare, reflecting the evolving landscape of the global economy. The annual development of the Nasdaq 100 recently has generally been positive, except for 2022, when the NASDAQ experienced a decline due to worries about escalating inflation, interest rates, and regulatory challenges.

Despite being one of the most successful technology companies, it has faced a lot of criticism from consumers. Some of the criticisms include tax avoidance, sweatshop use, and environmental destruction. Fortune 500 Companies In 2021, New York and California had the highest number of Fortune 500 companies, followed by Texas, Illinois, and Ohio. For New York, this can be attributed to its being the financial and cultural hub of the country. Fortune 500 Companies are ranked by Fortune magazine, which ranks the the top 500 companies in the United States based on revenue. Companies on this list are both publicly and privately held. The companies that get listed have changed over the years, for a variety of reasons such as company acquisitions, bankruptcies, and changes in the economy.

However, different sectors recovered at different rates to sit at widely different levels above their pre-pandemic levels. This suggests that the effect of the coronavirus on financial markets in the United States is directly affected by how the virus has impacted various parts of the underlying economy.

Which industry performed the best during the coronavirus pandemic?

Companies operating in the information technology (IT) sector have been the clear winners from the pandemic, with the IT S&P 500 sector index sitting at almost 65 percent above early 2020 levels as of November 2021. This is perhaps not surprising given this industry includes some of the companies who benefitted the most from the pandemic such as Amazon, PayPal and Netflix. The reason for these companies’ success is clear – as shops were shuttered and social gatherings heavily restricted due to the pandemic, online services such shopping and video streaming were in high demand. The success of the IT sector is also reflected in the performance of global share markets during the coronavirus pandemic, with tech-heavy NASDAQ being the best performing major market worldwide.

Which industry performed the worst during the pandemic?

Conversely, energy companies fared the worst during the pandemic, with the S&P 500 sector index value sitting below its early 2020 value as late as July 2021. Since then it has somewhat recovered, and was around 15 percent above January 2020 levels as of October 2021. This reflects the fact that many oil companies were among the share prices suffering the largest declines over 2020. A primary driver for this was falling demand for fuel fell in line with the reduction in tourism and commuting caused by lockdowns all over the world. However, as increasing COVID-19 vaccination rates throughout 2021 led to lockdowns being lifted and global tourism reopening, demand has again risen - reflected by the recent increase in the S&P 500 energy index.
