If you’re wondering what companies are in S&P 500, you’re asking about a prestigious list of 500 of the largest publicly traded companies in the United States. The S&P 500, or Standard & Poor’s 500, is a stock market index that tracks the performance of 500 of the largest publicly traded companies in the United States.
It is widely regarded as one of the best representations of the U.S. stock market and the broader economy. Furthermore, the S&P 500 is market-capitalization-weighted, meaning that companies with larger market capitalizations have a greater influence on the index’s performance.
How Are Companies Selected for the S&P 500?
Companies are selected for inclusion in the S&P 500 based on several key criteria:
- Market Capitalization: A company must have a market capitalization of at least $14.6 billion to be considered for inclusion.
- Liquidity: The company’s stock must be highly liquid (ratio of 0.75 or greater), meaning it is traded frequently and in significant volumes.
- U.S. Company: The company must be based in the United States.
- Public Float: At least 50% of the company’s shares must be available to the public for trading (a minimum of 250,000 shares in the previous six months before evaluation).
- Financial Viability: The company must have positive earnings in the most recent quarter, as well as over the sum of its most recent four quarters.
- Sector Representation: The S&P 500 aims to represent the major sectors of the U.S. economy, so the inclusion of companies is also based on their industry sector.
- Index Committee Review: The final selection of companies is made by the S&P 500 Index Committee, which reviews candidates based on these criteria and their overall contribution to the index’s market representation.
These criteria ensure that the S&P 500 remains a reliable benchmark for U.S. stock market performance, reflecting the health and diversity of the largest and most influential companies in the country.
