United States securities regulation
Securities regulation in the United States is the field of U.S. law that covers transactions and other dealings with securities. The term is usually understood to include both federal and state-level regulation by governmental regulatory agencies, but sometimes may also encompass listing requirements of exchanges like the New York Stock Exchange and rules of self-regulatory organizations like the Financial Industry Regulatory Authority (FINRA).
