Publicly traded companies Companies on the S&P 500 are publicly traded, meaning that anyone can invest in them.

As of October 6, 2025, 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 2025, the S&P 500 ESG index steadily outperformed the S&P 500 by ***** 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 that 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 ********* 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 ** 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.

This data-set has data spanning from 2013 till 2018. The S&P 500 stock market index, maintained by S&P Dow Jones Indices, comprises 505 common stocks issued by 500 large-cap companies and traded on American stock exchanges, and covers about 80 percent of the American equity market by capitalization. The index is weighted by free-float market capitalization, so more valuable companies account for relatively more of the index. The index constituents and the constituent weights are updated regularly using rules published by S&P Dow Jones Indices. Although the index is called the S&P "500", the index contains 505 stocks because it includes two share classes of stock from 5 of its component companies.

The dataset comprises of all the S&P 500 components with the records created for each stock's open and closing rate spanning from last 5 years.
