For nearly every stock purchase in the United States, yes, you do need a broker to invest in stocks. Federal rules keep individual investors off the exchanges themselves, so orders for shares listed on the New York Stock Exchange or Nasdaq have to go through a registered broker-dealer. The one real exception is buying shares straight from a company through a direct stock purchase plan, and even then a transfer agent, not you, handles the transaction. For practical purposes, the question isn’t whether to use a broker but which kind.
Why You Can’t Trade on an Exchange Yourself
Stock exchanges are not open to the public. The NYSE limits membership to SEC-registered broker-dealers with an established clearing relationship and states plainly that individual investors are not eligible.1NYSE. Trading at NYSE: Membership Nasdaq applies the same structure, requiring applicants to be registered U.S. broker-dealers that either clear directly or have a clearing arrangement with an approved firm.2Nasdaq Trader. U.S. Exchange Membership Those clearing firms do the back-end work of moving shares and cash between buyer and seller after a trade executes.
Oversight runs on two tracks. FINRA licenses and polices the people selling securities. The SEC regulates the firms and the market structure around them. Together the setup is designed to keep unqualified or fraudulent actors away from other people’s money, which is also why you can’t just log in to an exchange and buy a share yourself.
The One Way to Skip a Broker: Direct Stock Purchase Plans
Some publicly traded companies let you buy shares straight from them through a direct stock purchase plan. Instead of routing an order to an exchange, you purchase through the company’s stock transfer agent, which is the firm that keeps the official shareholder list, records ownership changes, issues certificates, and pays out dividends.3Investor.gov (U.S. Securities and Exchange Commission). Transfer Agents
To find out whether a company offers one, check the investor relations section of its website, which usually identifies the transfer agent.3Investor.gov (U.S. Securities and Exchange Commission). Transfer Agents Initial minimums commonly start around $100 to $500. Many plans also offer dividend reinvestment, which uses your cash dividends to buy more shares, including fractional ones.
Two limits are worth knowing before you count on this route. Only companies that have set up a plan offer one, so your choices are a small slice of the market. And purchases don’t execute on demand; the transfer agent typically batches them on a schedule. For a long-term holder of one or two specific companies, that works. For anyone who wants broad access or quick execution, a brokerage account is the right tool.
Types of Brokers and What They Cost
The industry doesn’t look the way it did ten years ago. Commissions that used to run $10 or more per trade have largely vanished for basic stock and ETF orders at the major online platforms. Brokers still make money, often through payment for order flow, where wholesale market makers pay the broker for the right to fill your order. The practical result for you is that opening an account and buying shares costs nothing upfront at most firms.
Brokers generally fall into three groups.
Full-service brokers pair you with a dedicated financial professional who makes personalized recommendations and manages your portfolio. Since June 2020, any broker-dealer making recommendations to retail customers must comply with the SEC’s Regulation Best Interest, which requires them to act in your best interest and not place their own financial incentives ahead of yours.4U.S. Securities and Exchange Commission. Regulation Best Interest: The Broker-Dealer Standard of Conduct Full-service advice typically costs 1% or more of assets under management each year, plus possible charges for financial plans.
Online discount brokers, including names like Fidelity and Schwab, let you research and place trades yourself with no per-trade commissions on most stocks and ETFs. You keep every decision. Nobody stops you from making a bad one either.
Robo-advisors sit in the middle. An automated platform builds and rebalances a diversified portfolio based on a questionnaire about your goals and tolerance for risk. Annual fees typically run 0.25% to 0.50% of your balance.
Whichever route you take, confirm the firm is a member of the Securities Investor Protection Corporation. SIPC protects up to $500,000 in securities and cash per customer if the brokerage itself fails, with a $250,000 sublimit on cash.5Securities Investor Protection Corporation. What SIPC Protects It does not cover losses from the market moving against you.
Taxable Account or IRA
Before you fund anything, decide what kind of account to open. The two main options are a standard taxable brokerage account and an individual retirement account, and the choice affects contribution limits and how your gains are taxed.
A taxable account has no contribution cap and no withdrawal restrictions. Put in what you want, sell when you want, use the money for anything. The cost is that dividends and realized gains are taxed in the year they happen.
An IRA gives you tax advantages in exchange for annual limits. For 2026, the maximum IRA contribution is $7,500, with an additional $1,100 catch-up contribution if you are 50 or older.6Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 A traditional IRA generally lets you deduct contributions now and pay tax at withdrawal. A Roth IRA takes after-tax dollars but makes qualified withdrawals in retirement tax-free.
Roth eligibility phases out at higher incomes. For 2026, the ability to contribute to a Roth IRA begins phasing out at $153,000 of modified adjusted gross income for single filers and is eliminated at $168,000; for married couples filing jointly, the phase-out runs from $242,000 to $252,000.7Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs Many investors use both account types: fund the IRA for its tax treatment, then put anything beyond the cap into a taxable account.
Opening a Brokerage Account
The online application takes about 10 to 15 minutes and collects more personal information than most people expect. Federal anti-money-laundering rules require every broker-dealer to run a Customer Identification Program before opening an account.8Financial Crimes Enforcement Network. USA PATRIOT Act At minimum the firm must collect your name, date of birth, a residential or business street address (not a P.O. box), and your taxpayer identification number, which for most individuals is a Social Security number.9eCFR. 31 CFR 1023.220 – Customer Identification Programs for Broker-Dealers You’ll also need a government-issued photo ID.
Expect questions about your employment, income, net worth, and investment experience. Under Regulation Best Interest, the broker needs this information to judge whether any recommendations fit your situation.4U.S. Securities and Exchange Commission. Regulation Best Interest: The Broker-Dealer Standard of Conduct Applying for options or margin brings more detailed questions about experience and risk tolerance.
You generally have to be at least 18 to open a standard brokerage account. A parent or guardian who wants a child to start sooner can open a custodial account under the Uniform Transfers to Minors Act or Uniform Gifts to Minors Act. The adult manages the account until the child reaches the age of majority, which is 18 or 21 depending on the state.
Cash Accounts vs. Margin, and the Day Trading Trap
A standard brokerage account is a cash account: you can only buy what your deposited money covers. A margin account lets you borrow from the broker to buy more, which amplifies gains and losses alike.
FINRA requires equity equal to at least 25% of the market value of the securities in a margin account at all times. Many brokers set higher house requirements and can raise them without advance notice. If your equity falls below the maintenance level, the broker issues a margin call for more cash or securities. The broker is not required to contact you before selling holdings to cover the shortfall, and even if they do give you a deadline, they can still sell immediately to protect their own position. You don’t pick which holdings go, and you owe any remaining balance if the sale doesn’t cover the debt.10FINRA.org. Margin Disclosure Statement For a first account, a cash account is almost always the right choice.
Active trading triggers another rule worth knowing. You’re classified as a pattern day trader if you execute four or more day trades within five business days and those trades represent more than 6% of your total activity in a margin account during that period. Once the label applies, you must maintain at least $25,000 in equity in that margin account on any day you day trade. If you fall below, the broker will restrict the account until you bring the balance back up, and the required equity has to be in place before you trade, not deposited after.11FINRA.org. Day Trading Newer investors regularly stumble into this by buying and selling the same stock a few times in a week and finding their account suddenly frozen.
