The United States equity market is the largest and most liquid in the world, home to over 5,000 publicly traded companies across every sector of the global economy. As the birthplace of modern capital markets, the U.S. hosts the world's most influential exchanges — the NYSE and NASDAQ — and serves as the primary listing destination for many of the world's largest corporations. Monetary policy set by the Federal Reserve, fiscal decisions from Washington, and macroeconomic data releases from U.S. agencies move not just domestic markets, but financial markets globally — making the U.S. market an essential focus for any serious investor regardless of geographic mandate.
