What Is Broker / Brokerage?
A broker (or brokerage firm) is an intermediary that facilitates the buying and selling of financial securities — stocks, bonds, ETFs, options, mutual funds, and more — on behalf of investors. Brokers provide access to exchanges and markets that individual investors cannot directly participate in.
Types of Brokers:
Full-Service Brokers: Offer comprehensive investment services including personalized advice, portfolio management, research, and financial planning. They assign individual advisors to client accounts. Examples: Merrill Lynch, Morgan Stanley, Edward Jones. Typically charge higher commissions or asset-based fees (1-2% of AUM annually). Best for investors who want hands-on guidance.
Discount Brokers: Execute trades at low or zero commission without providing personalized advice. Clients make their own investment decisions. Examples: Fidelity, Schwab, Vanguard, TD Ameritrade. The rise of discount brokers democratized investing; the 2019-2020 commission war drove commissions to $0 for stock/ETF trades.
Online Brokers: Digital platforms that combine discount broker functionality with robust tools, research, and education. Examples: Robinhood, Webull, Interactive Brokers. Some cater to active traders with advanced charting tools; others focus on simplicity for beginners.
What Brokers Provide:
- Trade execution: Access to stock exchanges, bond markets, options markets
- Account custody: Safekeeping of your securities (protected by SIPC up to $500,000 in the U.S.)
- Research: Market analysis, earnings reports, analyst ratings
- Margin lending: Ability to borrow against your portfolio
- Tax reporting: 1099 forms for tax purposes
How Brokers Make Money (When Trades Are "Free"): Even zero-commission brokers earn revenue through:
- Payment for order flow (PFOF): Routing orders to market makers who pay for the privilege
- Interest on margin loans: Lending money to investors
- Cash sweep programs: Keeping uninvested cash in low-yield accounts
- Premium features: Subscriptions for advanced tools
- Spread on options/fixed income: Earning on the bid-ask spread
SIPC Protection: In the U.S., brokerage accounts are protected by the Securities Investor Protection Corporation (SIPC) up to $500,000 ($250,000 cash) if a broker fails. This does not protect against investment losses — only against broker insolvency.
Broker / Brokerage Example
- 1An investor opens a Fidelity brokerage account, deposits $5,000, and buys 10 shares of Apple stock at $170. Fidelity executes the trade on the NASDAQ, holds the shares in custody, and charges $0 commission for the transaction
- 2A high-net-worth investor works with a Merrill Lynch advisor who actively manages their $2M portfolio, provides tax-loss harvesting recommendations, and charges 1% of assets annually ($20,000/year) for the comprehensive service
