Broker-Dealer A person or firm in the business of buying and selling securities operating as both a broker and a dealer depending on the transaction. Investopedia Says: Technically, a broker is only an agent who executes orders on behalf of clients, whereas a dealer acts as a principal and trades for his or her own account. Because most brokerages act as both brokers and principals, the term broker-dealer is commonly used to describe them.
