Broker
A securities broker acts as an agent in effecting transactions for customers, handling orders, routing, execution, and transaction records.
Compare brokerage firms, registered representatives, stockbroker terminology, and venue-floor roles by capacity, activity, and responsibility.
Brokerage labels can refer to a legal firm, an agency capacity, an individual registration, an informal occupation, or a venue-specific execution role. The most useful question is not “Which type sounds best?” but “Who is acting, for whom, in what capacity, and under which rules?”
| Term | What it identifies | What it does not establish |
|---|---|---|
| Broker | Agency activity effecting a transaction for another party | Advisory authority, principal trading, or a particular service level |
| Stockbroker | Informal label for a brokerage firm or securities professional | A specific legal registration category |
| Registered Representative | U.S. person registered through a member firm for specified activities | Permission to perform every securities or advisory function |
| Floor Broker | Agent representing orders on a physical exchange floor | Market-making, retail account custody, or investment advice |
| Traditional Broker-Dealer | Established brokerage and dealer business model | A separate regulatory category or an absence of modern technology |
A single transaction can involve:
One firm may perform several functions, or each may belong to a different firm. The account agreement, order record, confirmation, and statement provide stronger evidence than a marketing title.
Use these questions whenever a broker-related term appears:
Capacity can change across services and transactions. A dually registered professional may use brokerage capacity for one interaction and advisory capacity for another, but the distinction should be clear.
