The S&P 500 Index, the broadest American stock index

To measure the performance of American stocks and assess the evolution of the US financial markets and economy, the stocks of the 500 largest publicly listed companies in the United States are aggregated in the S&P 500 index, also more simply known as the S&P. This capitalization-weighted index, which gives more weight to larger companies, is considered to be one of the best benchmarks for the American stock market, and for the broader US economy.

Based upon the stocks of 500 companies, the S&P has a broader base than the 30 Dow Jones companies, even though many companies in the Dow Jones index are also top constituents of the S&P. The S&P also has a wider spectrum of sectors and industries than the Nasdaq Composite companies, which is heavily skewed toward the technology sector.
