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.

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.

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.

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 ** 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.
