The index's history can be traced back to the formation of the Standard Statistics Company in 1923, which later merged with Poor's Publishing Company in 1941 to become Standard & Poor's Corporation (S&P). Initially, the company published a composite index of 90 stocks called the Composite Index. Over time, this index evolved and expanded to become the S&P 500 in 1957.

The S&P 500's composition is determined by a committee at S&P, which selects companies based on specific criteria, including market capitalization, liquidity, and representation of the US economy. The companies included in the index represent a significant portion of the total market value of the US stocks.

The S&P 500's performance during major market events can vary significantly. Here's a brief overview of how the index performed during some notable historical periods:

  • S&P lost around 30% of its value during the Black Monday stock market crash.
  • During the dot-com bubble crisis, the S&P rose by 2.4% and performed better than other indexes. In fact, from March 1998 to March 2000, the S&P 500 saw a substantial increase of 38.1%.
  • During the 2008 housing crisis, S&P500 was down 57% from its high prices. 
  • Even though when the COVID-19 pandemic impacted the US economy and financial markets, the S&P 500 experienced a significant decline of 25% in 2020, it showed remarkable growth since reaching its lowest point during the Covid pandemic. It more than doubled on a closing basis from its trough of 2,237.40 in 2021.

What is the significance of the S&P 500? 

The S&P 500 plays a crucial role in assessing the overall health and performance of the US stock market. It measures the performance of 500 large-cap companies (such as Apple, Microsoft, Amazon, and more), selected based on specific criteria, which represent a significant portion of the total market value of US stocks.

The index covers a diverse range of sectors, including technology, healthcare, finance, consumer goods, energy, and more. The S&P 500 provides a comprehensive representation of the US economy by including companies from various sectors.


How is the S&P 500 calculated?

Instead of considering the stock prices of the constituent companies, the S&P 500 focuses on their float-adjusted market capitalization. ‘Float-adjusted’ means that only the shares available to the public are taken into account, excluding shares held by management, governments, or other companies. 

This adjustment is made to provide a more accurate representation of the market value accessible to the public.

Here is how the S&P 500 is calculated: 

  1. Selecting constituent companies: A committee at S&P Dow Jones Indices, the organization behind the S&P 500, determines which companies are included in the index. The selection process considers factors like market capitalization, liquidity, and representation of the US economy. The goal is to include 500 of the largest and most significant publicly traded companies in the United States.
  2. Calculating market capitalization: The market capitalization of each company is calculated by multiplying its stock price by the number of outstanding shares. This determines the total value of the company's equity in the market.
  3. Determining weightage: Each constituent company's weight in the index is determined by its market capitalization relative to the total market capitalization of all companies in the index. The larger a company's market capitalization, the higher its weight in the index.
  4. Calculating the index: The S&P 500 index value is calculated by adding up the market capitalization-weighted values of all constituent companies. This calculation considers changes in stock prices and adjustments for factors like stock splits, dividends, and corporate actions.
  5. Maintaining the index: The index is regularly reviewed and rebalanced to ensure it remains representative of the market. Changes may be made to the constituent companies based on factors like mergers, acquisitions, or significant shifts in market capitalization. The index methodology aims to maintain continuity and accurately reflect the market's performance over time.


What are the criteria for companies to be included in the S&P 500?

US-based: Companies must be headquartered in the United States.

Market capitalization: Companies must have a minimum market capitalization of at least $8.2 billion. Market capitalization represents the total value of a company's outstanding shares and is calculated by multiplying the stock price by the number of shares available to the public.

Listing on an eligible US exchange: Companies must be listed on an eligible US stock exchange like NYSE, NASDAQ, etc. This requirement ensures that the company's shares are actively traded and readily accessible to investors.

Corporate structure: Eligible companies must be structured as corporations and offer common stock to investors.

Positive earnings: Companies must have positive as-reported earnings not only for the most recent quarter but also for the cumulative total of the four most recent quarters. This criterion ensures that included companies demonstrate consistent profitability.

Benefits of investing in S&P 500

1. Includes some of the biggest US companies 

The S&P 500 comprises some of the largest and most influential companies not just in the United States but globally. These companies have established track records, significant market capitalization, and a strong presence in their respective industries. By investing in the S&P 500, investors gain exposure to these prominent companies, which can provide stability and potential for long-term growth.

2. Tight spreads

The S&P 500 is a highly liquid and widely traded index. This liquidity results in tight bid-ask spreads, which means that the difference between the buying and selling prices of the index is narrow. Tight spreads benefit investors as they minimize transaction costs and enhance the overall trading efficiency.

3. Consistent monitoring is not necessary

The S&P 500 is a passive investment option, meaning that it tracks the performance of the underlying index without the need for active management. Investors who choose to invest in S&P 500 index funds or exchange-traded funds (ETFs) can benefit from not needing to monitor individual stocks constantly. This passive approach saves time and effort, making it a convenient choice for investors who prefer a hands-off approach.

4. Fosters diversification

The S&P 500 includes companies from a wide range of sectors, such as healthcare, automobile, technology, finance, consumer goods, and more. This sector diversification helps mitigate risks associated with individual stocks or specific industries. By investing in the S&P 500, investors gain exposure to a diversified portfolio of companies, which can potentially reduce the impact of any single company or industry's poor performance on the overall investment.

However, it is important to understand the risks associated with trading S&P 500. The S&P 500, like any other stock market investment, is susceptible to market volatility, and its value can fluctuate. Economic conditions, geopolitical events, and industry-specific issues can all have an impact on the index's and underlying companies' performance. Before investing in the S&P 500 or any other stock market index, traders must analyze their risk tolerance, carry out thorough analysis, and carefully consider their investment plan.
