Stock market indices in the U.S. - statistics & facts
U.S. stock market indices are particularly important due to the size and diversity of the U.S. economy, the global reach of its companies, and their historical significance. Stock market indices are statistical measures that track the performance of a specific group of stocks used by investors and analysts as benchmarks to assess the overall health of the stock market, make investment decisions, and gauge market trends. Being home to the largest stock exchanges in the world - the New York Stock Exchange (NYSE) and the Nasdaq Stock Market - the U.S. is the most attractive market for companies and investors, both domestic and international.
