What it is:
A listed security is a Stock exchange or the ., , , , , or other security that trades on a national exchange such as the New York
How it works/Example:
The Big Board, also known as the New York Stock Exchange (NYSE) is the first and most popular place for listed securities. It was created in 1792 when two dozen stockbrokers and merchants signed the Buttonwood Agreement. The first company it listed was the Bank of New York.
When a company has listed securities, it usually must make regular public filings with the SEC. These filings detail the company's business operations and financial performance, among other things. The 10-K is just one of many forms a company with listed securities in the U.S. must file with the SEC. SEC regulations S-X and S-K (as well as the instructions to the form itself) dictate the specific elements, presentation and disclosure requirements of the 10-K.
Stocks, , mutual , exchange-traded , and can be listed as securities. The exchanges that list these securities monitor the issuers and are subject to a considerable amount of regulation from several federal agencies, such as the Federal Reserve, and from a host of laws, such as the Securities Exchange Act of 1934. The Securities and Exchange Commission (SEC) is the weightiest of the regulators -- it supervises the and all national exchanges, brokerage and institutions, and other participants in the securities markets. The NYSE must also comply with each state's own securities laws.
When the prices of any listed securities are moving up or down rapidly, the exhanges may restrict trading (primarily to reduce the large number of program trades that occur in an average trading session).
