In 1957, it expanded to include approximately 500 companies, formalizing the structure familiar today[3]. Over the decades, the index has evolved into a cornerstone of global finance, reflecting the dynamism of the U.S. economy and the rise of sectors like technology, healthcare, and consumer goods. ## Purpose and Impact The S&P 500 serves multiple critical roles: it is a benchmark for investment portfolios, a basis for passive index funds and ETFs, and a key input for economic forecasting tools like the Conference Board Leading Economic Index[1][6]. For companies, inclusion in the S&P 500 is prestigious and financially impactful, often triggering significant buying activity as funds tracking the index adjust their holdings[2]. For investors, the index offers a convenient, diversified exposure to the U.S. equity market through index funds and ETFs[4
