A stockbroker is an individual licensed to execute securities transactions for customers as the agent of a broker-dealer, compensated historically by commissions on the trades and products the customer buys. The word is a cultural label rather than a legal category — the underlying registration is that of a registered representative, earned through FINRA exams and firm sponsorship. As commissions on stock trades collapsed to zero and self-directed platforms absorbed order-taking, the stockbroker's economic role migrated toward packaged products, managed-account referrals, and advice-flavored titles, but the regulatory chassis — firm supervision, FINRA rules, Regulation Best Interest for retail recommendations — is unchanged.
Stockbroker
A stockbroker is the everyday name for a licensed securities salesperson — formally a registered representative of a broker-dealer — who buys and sells investments for customers. The classic commission-per-trade stockbroker has largely given way to app-based trading and advice-branded roles.

Quick Summary
- "Stockbroker" is the colloquial title; the legal one is registered representative, licensed through a FINRA member broker-dealer.
- The traditional model — call your broker, pay a commission per trade — has mostly disappeared into self-directed platforms and zero-commission trading.
- People doing stockbroker work today usually carry titles like financial consultant or advisor, which blurs the line between selling and advising.
- Brokers recommending securities to retail customers operate under Regulation Best Interest, not a fiduciary duty.
- Any broker's licenses and disciplinary history are public at brokercheck.finra.org.

Advanced Explanation
The arc of the stockbroker is a good compressed history of retail investing. For most of the twentieth century, individual investors could not reach the market without one: fixed commissions made every trade expensive, and the broker was gatekeeper, salesperson, and tipster at once. Deregulation of commissions in 1975 created the discount brokerage; the internet created self-directed trading; and by the time major platforms cut stock commissions to zero in 2019, the order-taking function that defined the job had no price attached to it at all.
What remains is the sales function, redistributed. Where the revenue once came from trade commissions, it now comes from products that still pay — mutual fund loads, variable annuities, structured notes — and from converting transactional customers into fee-paying managed accounts. The people doing this work rarely call themselves stockbrokers; business cards say financial consultant, wealth advisor, or vice president. The title inflation matters because the duty did not inflate with it: a broker's obligation to a retail customer is Regulation Best Interest, attached to each recommendation, not the ongoing fiduciary duty an investment adviser owes.
The word still does honest work in one place: describing the transaction-compensated role itself. When you want to know whether the person across the table is functionally a stockbroker, the tells are the registrations (Series 7 on BrokerCheck), the compensation (paid by transactions and products), and the paperwork (a brokerage account agreement and Form CRS rather than an advisory agreement).
How to Remember
The title changed; the chassis didn't. If the compensation arrives per transaction or per product, you're looking at a stockbroker's economics — whatever the business card says.
Used in a Sentence
“Nadia's grandfather phoned his stockbroker to place every trade and paid a commission each time; Nadia taps a phone app and pays none — the same function, priced to zero.”
How It Works
In the surviving full-service model, a broker maintains a book of customer relationships, recommends securities and products the firm has approved, and is compensated through a payout grid — the firm collects commissions, loads, and concessions, and shares a percentage with the broker.
A hypothetical example of why the economics still matter: Frank, 66, rolls $300,000 out of his 401(k) and visits the brokerage branch his bank referred him to. The consultant — a registered representative — recommends a variable annuity paying the firm a commission of several percent of the premium, a meaningful one-time payout on a $300,000 ticket. An advice-only planner reviewing the same rollover for a flat fee might conclude a plain low-cost IRA portfolio fits Frank better. Neither recommendation is automatically wrong — but one is made inside a compensation structure that pays only if the product sells, which is exactly what Regulation Best Interest requires the firm to disclose and mitigate. (Hypothetical, for illustration.)
Pros and Cons
Pros
- Licensed, supervised, and publicly accountable — exams, firm compliance, and a permanent BrokerCheck record stand behind the role.
- For investors who want a human to handle execution and product access, the full-service channel still delivers it.
- Regulation Best Interest requires cost-and-alternatives analysis on every retail recommendation — a real floor under the sales function.
Cons
- Transaction and product compensation is the defining conflict — the broker eats when the customer buys, not when the advice proves right.
- Advice-flavored titles obscure the sales role, and most customers never learn the difference between Reg BI and fiduciary duty.
- No ongoing duty to monitor your account attaches to a brokerage recommendation — the obligation ends at the point of sale.
People Also Asked
Answers to the most frequently asked questions.
Do stockbrokers still exist?
The function exists; the job title has mostly retired. Order-taking moved to self-directed apps with zero commissions, and the humans who once phoned in trades now work as advisors or consultants at brokerage firms, compensated mainly by packaged products and managed-account fees. Legally they remain registered representatives of broker-dealers, which is what "stockbroker" always meant underneath.
What is the difference between a stockbroker and a financial advisor?
"Financial advisor" is an unregulated umbrella title that both salespeople and fiduciary advisers use. A stockbroker specifically means someone licensed to sell securities through a broker-dealer, compensated by transactions and products, and governed by Regulation Best Interest. Some advisors are only that; others are investment adviser representatives owing a fiduciary duty; many are both. The registrations — not the title — tell you which.
How did stockbrokers get paid, and how do they get paid now?
Historically, by commissions on every trade — which is why the old model generated so much phone-call salesmanship. Today stock-trade commissions at major retail platforms are zero, and broker compensation flows from products that still carry payouts (fund loads, annuities, structured products), margin and cash economics at the firm level, and the conversion of customers into fee-based managed accounts.
Is a stockbroker allowed to give me investment advice?
Yes, incidental to selling — recommending securities is the core of the job, and Regulation Best Interest governs those recommendations to retail customers. What a broker cannot do without separate investment-adviser registration is hold themselves out as providing ongoing advisory services for a fee. That line — advice incidental to transactions versus advice as the product — is the historical boundary between the brokerage and advisory professions.
Have a question a definition can't answer?
Advice-only advisors answer questions like this for a transparent flat fee — no products, no commissions, no asset management.
