The S&P 500 is one of the most influential stock indices in the world. Created by Standard & Poor’s, the index tracks 500 large-cap publicly listed companies in the United States. Its primary purpose is to reflect the overall performance of the U.S. stock market and is widely used as an “economic barometer” or a benchmark to measure the performance of investment portfolios and mutual funds.
