The S&P 500 is a stock market index that measures the performance of 500 large-cap companies listed on the US stock exchanges. The index is widely regarded as a barometer of the overall health and performance of the US stock market and is considered to be one of the most important indicators of the US economy.

The S&P 500 is maintained by S&P Dow Jones Indices, which is a division of S&P Global. The index was first introduced in 1957 and has since become one of the most widely followed stock market indices in the world.

To be included in the S&P 500, companies must meet certain criteria, including having a market capitalization of at least $8.2 billion and a minimum float-adjusted market cap of $4.1 billion, as well as meeting certain liquidity and financial viability requirements.

The index is weighted by market capitalization, which means that companies with larger market caps have a greater impact on the overall performance of the index. This is in contrast to other indices, such as the Dow Jones Industrial Average, which is weighted by price.

The S&P 500 is often used as a benchmark against which the performance of mutual funds, exchange-traded funds (ETFs), and other investment vehicles is measured. For example, a mutual fund that invests in large-cap US stocks may be benchmarked against the S&P 500.

Investors can gain exposure to the S&P 500 through a variety of investment vehicles, including mutual funds, ETFs, and index futures and options. Because the S&P 500 is a widely followed and highly liquid index, it is often used as a basis for financial derivatives such as futures contracts and options.

The composition of the S&P 500 is reviewed and adjusted periodically to ensure that it remains representative of the US stock market. Companies can be added or removed from the index based on changes in their market capitalization, financial viability, or other factors.

Overall, the S&P 500 is an important indicator of the health and performance of the US economy, and is closely watched by investors and analysts alike. Its performance can be influenced by a wide variety of factors, including economic trends, political events, and global market conditions.
