What Is a Broker?
A broker is a person or firm that buys or sells securities for customers or otherwise helps carry out financial transactions. In securities markets, brokers often operate through broker-dealers, which may act for customers, for their own account, or both.
Investors commonly use brokers to open accounts, place trades, access investment products, receive recommendations, and hold securities through a brokerage platform.
Key Takeaways
- A broker helps customers buy and sell securities or access financial markets.
- Broker-dealers may act as brokers, dealers, or both.
- Brokers can be full-service, discount, online, or specialized.
- When making recommendations, brokers must meet applicable conduct standards.
- Investors should check registration, fees, conflicts, services, and disciplinary history.
How Brokers Work
A broker receives customer orders and routes or executes them under market rules. The customer may pay commissions, markups, markdowns, account fees, margin interest, or other costs depending on the broker and account type.
Some brokers provide recommendations and investment guidance. Others mainly provide execution and custody tools. The level of service affects cost, responsibilities, and what the investor should expect.
Broker Types and Services
Type | Typical service | Common consideration |
|---|---|---|
Full-service broker | Recommendations, planning, and trade execution | Higher cost and potential conflicts |
Discount or online broker | Self-directed trading platform | Investor does more decision-making |
Broker-dealer | Acts as broker for customers or dealer for its own account | Role can affect pricing and conflicts |
Specialized broker | Focuses on products such as bonds, options, or private placements | Product risks and liquidity matter |
Why It Matters
A broker is often the investor's main gateway to the financial markets. The broker's platform, fees, order handling, product menu, margin policies, and customer support can affect the investor's experience and cost.
Broker selection also affects investor protection. Registration, account statements, trade confirmations, disclosures, and regulatory oversight all matter when a firm holds assets or handles transactions. Investors can use registration and disciplinary-history tools before opening or funding an account.
Limits and Misunderstandings
A broker is not automatically the same as an investment adviser. Brokers often provide transaction-based services, while investment advisers generally provide advice for compensation under a different regulatory framework.
Investors should also understand how the broker is paid. Commissions, spreads, payment for order flow, revenue sharing, product compensation, and margin interest can create incentives that deserve attention.
The Bottom Line
A broker helps investors access markets and execute transactions. Choosing one should involve more than convenience: fees, services, conflicts, registration, and the broker's role in each transaction all matter.
