A brokerage account is an investment account at a registered brokerage firm that allows you to buy and sell investments such as stocks, bonds, mutual funds and exchange-traded funds. Two broad account types are cash accounts and margin accounts, and the distinction matters because margin involves borrowing.
Cash account vs. margin account
| Account type | How purchases are funded | Major risk |
|---|---|---|
| Cash account | You pay the full amount for securities purchased | Investment losses on the money invested |
| Margin account | Broker may lend money using account securities as collateral | Losses can be amplified; margin calls and forced sales are possible |
Investor.gov warns that a brokerage firm can require additional cash or securities in a margin account if values fall, and under certain conditions can sell securities to cover a shortfall. Margin therefore adds financing risk on top of normal market risk.
What you can hold in a brokerage account
Depending on the firm, a brokerage account may provide access to stocks, bonds, ETFs, mutual funds and other securities. Availability does not mean every product is suitable for every investor.
Start with the purpose of the money, time horizon, need for liquidity and ability to tolerate loss before choosing investments. EconomicHQ’s Investing for Beginners guide covers the broader foundation.
Fees still matter even when trades are advertised as commission-free
A brokerage may charge no commission for some trades and still have other costs. Potential expenses include fund expense ratios, options fees, margin interest, wire or transfer fees, account-service fees and bid-ask spreads embedded in trading.
Small recurring costs can compound over long periods. Before opening an account, read the broker’s fee schedule and the expense information for any fund you are considering.
Check the broker and read Form CRS
Investor.gov recommends reviewing a firm’s relationship summary, commonly called Form CRS, which is designed to help retail investors understand services, fees, conflicts and disciplinary information. Investors can also check the background of investment professionals through regulator resources.
Do not rely only on an app-store rating, social-media recommendation or promotional bonus.
Understand what happens to uninvested cash
Brokerage firms may place uninvested cash into a sweep arrangement, money market fund or bank deposit program, depending on the account. Those arrangements can have different yields, protections and terms.
Read the brokerage disclosure so you know where idle cash goes and whether the protection is SIPC coverage for securities/cash held at a brokerage, FDIC insurance through a bank sweep, or another arrangement. Those systems are not interchangeable.
Brokerage account versus retirement account
A standard taxable brokerage account generally does not have the same tax advantages or contribution rules as an IRA or employer retirement plan. The right account type depends partly on the purpose of the money and tax situation.
This article focuses on the mechanics of brokerage accounts, not personalized tax planning.
Questions to ask before opening an account
- Is this a cash account or margin account?
- What investments are available?
- What commissions, fund fees, margin rates and transfer fees may apply?
- Where does uninvested cash go?
- What research and support tools are provided?
- What is the firm’s Form CRS?
- Is the broker or investment professional properly registered?
- How easy is it to transfer the account later?
Keep account choice separate from investment hype
A brokerage account can be useful infrastructure for long-term investing, but easy trading access can also encourage unnecessary activity. The account should serve a defined financial plan rather than turn investing into an entertainment loop.
