SEC: The abbreviation for Securities and Exchange Commission, which is a federal government agency that regulates the trading of corporate stock to protect investors against unscrupulous practices. Like a number of other federal regulatory agencies, the SEC was established in the 1930s--1934 to be exact.

The SEC has all sorts of rules governing the stock market, including information disclosure, insider trading, speculation, and use of credit.
