January 28, 2025

The S&P 500 is a stock market index that tracks the performance of the 500 largest publicly traded companies in the United States. It is one of the most well-known and widely followed indices in the world, and often referred to as the "stock market barometer."

Background

The S&P 500 was created in 1923 by Standard & Poor's, a financial services company. The index is weighted by market capitalization, which means that larger companies have a greater impact on the index's value than smaller companies.

The S&P 500 is widely used as a gauge of the overall performance of the U.S. stock market. It is often used by investors to track the performance of their portfolios, and by economists to measure the health of the U.S. economy.
