What is the S&P 500？

The S&P 500 is a stock market index consisting of the 500 largest publicly traded companies in the United States and is one of the primary stock market indicators in the country.

Three years later, a new index featuring 90 companies was introduced, providing daily quotations.

In 1941, Standard Statistics merged with Poors Publishing, a company founded by Henry Varnum Poor, who had published an investment guide for the railroad industry in 1860. By 1957, the index created by Standard Statistics expanded to include the 500 most relevant companies of the time, giving rise to the well-known S&P 500.Over the years, the S&P 500 has gained importance and has become a key indicator of the U.S. market, attracting global investors due to its positive returns over time.
