Legal Definitions - securities broker

A securities broker is a person or firm that conducts securities transactions for the accounts of others. They act as intermediaries between buyers and sellers of securities, such as stocks and bonds. Securities brokers are different from securities dealers, who trade as principals before selling the securities to a customer.

Examples of securities brokers include:

• A brokerage firm that executes buy and sell orders for customers
• An institutional broker who trades securities for institutional clients like banks and pension funds
• A registered broker who is required to be registered under the Securities Exchange Act of 1934

For example, if you want to buy shares of a company, you can contact a securities broker who will execute the trade on your behalf. The broker will charge a commission for their services.
