Overview
The S&P 500 is more than just a stock market index; it's a real-time barometer of the U.S. economy's health, representing the 500 largest publicly traded companies across various sectors. Since its inception in 1957, it has become the benchmark for institutional investors and a widely watched indicator of market performance.
