The S&P 500 is a stock market index that measures the performance of 500 large companies listed on stock exchanges in the United States. It is one of the most commonly followed equity indices and is considered a key indicator of the overall health of the U.S. stock market. It is not a share of ownership in the Standards & Poor Corporation; rather, it is a measurement of the 500 biggest companies in the stock market.
