Third market(redirected from third markets)
Also found in: Dictionary.
Exchange-listed securities, such as those that are traded on the New York Stock Exchange (NYSE) or the American Stock Exchange (AMEX), may also be bought and sold off the exchange, or over-the-counter (OTC), in what is known as the third market.
Typically, third-market transactions are large block trades involving securities firms and institutional investors, such as investment companies and pension funds.
With the growth of electronic communications networks (ECNs), more institutional investors are buying and selling in this way. Among the appeals of the third market are speed, reduced trading costs, and anonymity.
