Brokerage Accounts
What a brokerage account is, how to open and fund one, what protections you get, and the features that actually matter when you choose where to invest.
Your doorway to the market
You cannot buy shares directly on a stock exchange. You need a broker, a firm licensed to place trades on your behalf and hold your investments. A brokerage account is the account you open with that firm. It holds cash waiting to be invested plus every stock, ETF and fund you buy.
Opening one usually takes a few minutes online. You provide your name, address, date of birth, Social Security or tax number, employment information and answers about your investing experience. Brokers are required to verify your identity, so have a photo ID ready.
How money moves in
Most people link a bank account and transfer money electronically. Deposits usually take one to a few business days to arrive, although some brokers let you trade part of a deposit right away. Once the cash is in the account, you can place orders.
Transfer from your bank, let the cash settle, then place your order.
Settlement: when a trade becomes final
When you buy or sell a stock, the trade is agreed instantly, but the official exchange of cash and shares happens later. As of 2026, most US stock and ETF trades settle one business day after the trade date, known as T+1. This matters mainly for cash accounts: money from a sale is not fully settled until the next business day.
Cash account vs. margin account
A cash account lets you invest only the money you have deposited. A margin account also lets you borrow from the broker using your investments as collateral. Borrowing magnifies both gains and losses and can trigger a margin call, where the broker demands more money or sells your holdings. Beginners are usually best served by a cash account.
| Feature | Cash account | Margin account |
|---|---|---|
| Invest with | Your own deposited money | Your money plus borrowed money |
| Can you lose more than you put in? | No | Yes |
| Interest charged | None | On any amount borrowed |
| Short selling | Not allowed | Allowed with approval |
| Best for | Most beginners and long-term investors | Experienced traders who manage risk |
General comparison of US brokerage account types.
What protects your account
In the US, brokers must keep customer assets separate from the firm’s own money. If a member brokerage fails, SIPC protection covers up to $500,000 per customer, including up to $250,000 in cash, for missing securities and cash. SIPC does not protect you from investment losses when prices fall. It protects you if the broker itself goes under and your assets are missing.
Features that matter
Most large online brokers now charge $0 commissions on US stock and ETF trades, so compare other things.
- Fractional shares, so you can invest exact dollar amounts.
- Automatic recurring investments into funds or ETFs.
- Account types offered: taxable, IRAs and custodial accounts.
- Good trade execution, clear statements and easy tax forms.
- Customer support you can actually reach, and strong security such as two-factor login.
Your first order
Start small. Choose a broad index ETF, type the ticker, enter a dollar amount or number of shares and pick an order type. A limit order sets the most you will pay; a market order fills right away at the best available price. For big, busy ETFs during normal market hours, either works well. Then review the confirmation and watch the position appear in your account.
Market orders fill fast; limit orders control price.
Common mistakes
- Opening a margin account without understanding the risk.
- Trading unsettled cash repeatedly in a cash account.
- Choosing a broker only because of a sign-up bonus.
- Skipping two-factor login and strong passwords.
- Placing market orders before the open or in thinly traded securities.
Other account types
Besides a standard individual account, most brokers offer joint accounts for couples, custodial accounts that adults manage for children until they come of age, retirement accounts such as IRAs, and trust or business accounts. You can hold several accounts at the same broker and move money between them, subject to each account’s rules. Choosing the right type up front saves paperwork later.
Moving an account
If you ever switch brokers, you usually do not need to sell your investments. A transfer system lets the new broker pull your holdings over in kind, typically within about a week. Selling first can trigger taxes in a taxable account, so ask the new broker to handle an in-kind transfer instead. Some brokers charge an outgoing transfer fee, and some new brokers will reimburse it.
Key takeaways
- A brokerage account holds your cash and investments at a licensed firm.
- Most US trades settle one business day later (T+1) as of 2026.
- Cash accounts limit you to your own money; margin adds borrowing and risk.
- SIPC protects against a broker failing, not against market losses.
- Compare features like fractional shares, automation and account types.
