What is the S&P 500?

The S&P 500, or Standard & Poor's 500, is a stock market index that tracks the stocks of 500 large-cap companies listed on stock exchanges in the United States. The index is considered a leading indicator of U.S. equities and reflects the overall performance of the American economy. It includes companies from various sectors, including technology, healthcare, finance, and consumer goods.

Key Features of the S&P 500

  • Widely used as a benchmark for mutual funds and exchange-traded funds (ETFs).

History of the S&P 500

The S&P 500 was introduced in 1957 by Standard & Poor's, a financial services company.
