Instinet (Institutional Networks Corporation)
Instinet.
Instinet is the world's largest agency brokerage firm.
As an agency firm, it doesn't trade stock for its own account as traditional brokerage houses do. That way, it doesn't bid against the mutual funds, insurance companies, pension funds, and other institutional investors who are its primary clients.
Using Instinet's sophisticated electronic network, these investors can trade directly and anonymously with each other in more than 40 global markets. Or, using Instinet brokers, the investors can place orders on all US exchanges and many overseas exchanges, including those that aren't automated.
