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.

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.
