FINRA is the self-regulatory body that polices brokers and brokerage firms in the United States. It writes the rules, runs the licensing exams, investigates bad behavior, and – most usefully for you – operates BrokerCheck, a free database where you can look up any broker or firm and see if they’ve been sanctioned, sued, fined, or banned.

If you’ve ever signed up for a robo-advisor, your money is sitting at a FINRA-registered broker-dealer. That’s the only reason most people need to care about this acronym – and honestly, BrokerCheck is the only part of FINRA’s website you’ll ever actually open.

Key Takeaways

  • FINRA is a private, non-governmental organization that oversees ~3,400 brokerage firms and 600,000+ registered brokers in the US.

  • It can fine, suspend, and ban brokers – but it can’t bring criminal charges. That job belongs to the SEC and the DOJ.

  • BrokerCheck is the part worth bookmarking. Before you trust any firm with your money, run them through it.

What is FINRA?

FINRA stands for the Financial Industry Regulatory Authority. It’s a non-profit, non-governmental self-regulatory organization (an “SRO” in regulator-speak) that was created in 2007 when the NASD merged with the regulatory arm of the NYSE. It’s authorized by Congress and supervised by the SEC, but technically it’s run by the industry it regulates – which is either pragmatic or a conflict of interest depending on who you ask.

FINRA oversees roughly 3,400 brokerage firms and more than 600,000 registered representatives. Every legitimate broker-dealer in the US has to be a FINRA member. That includes the broker-dealers behind every major robo-advisor: Betterment Securities, Wealthfront Brokerage, Schwab, Fidelity, the works.

Key Roles and Responsibilities of FINRA

FINRA's three core functions: rulemaking, licensing, and enforcement

FINRA does three things that matter: it writes the rulebook, it licenses the people who sell securities, and it goes after firms that break the rules.

Regulation of Brokerage Firms

FINRA writes and enforces the rules that brokerage firms have to follow. The most famous of these is FINRA Rule 2010, which requires members to “observe high standards of commercial honor and just and equitable principles of trade.” It sounds quaint, but it’s the catch-all that gets cited every time a broker does something shady that doesn’t fit a more specific rule.

FINRA also runs routine examinations of member firms (annual for the big ones, less often for smaller shops), checking compliance, books and records, advertising, and how firms handle conflicts of interest. If you’ve ever wondered why your robo-advisor’s marketing emails contain a small library of footnotes, this is why.

Administering Qualifying Exams

If you’ve ever spoken to a human “advisor” at a brokerage, they’ve passed at least one FINRA exam to be allowed to do that. The Series 7 is the big one – 125 questions, 225 minutes, covers stocks, bonds, options, packaged products, regulations, and ethics. There’s also the Series 6 (limited products), Series 63 (state rules), Series 65 (advisors), and Series 66 (combo of 63 and 65).

None of this applies if you only ever interact with the robot – robo-advisor algorithms don’t take the Series 7. But the humans who designed and oversee them do.

Market Surveillance and Enforcement Actions

FINRA’s market surveillance team watches trading data for patterns that look like fraud, manipulation, or insider trading – spoofing, wash trades, layering, that kind of thing. When something turns up, FINRA can investigate, bring its own disciplinary case, and either fine or ban the people involved.

For anything that crosses into criminal territory, FINRA refers the case to the SEC, DOJ, or state regulators. It refers around 1,000 cases a year. Over the last five years, its enforcement work has produced more than $170 million in restitution for harmed investors – a number that sounds large until you compare it to what the actual fraudsters made.

BrokerCheck: The Only FINRA Tool You’ll Actually Use

BrokerCheck lets investors look up the disciplinary history of any US broker or firm

BrokerCheck is FINRA’s public-facing database. Type in the name of a brokerage, an advisor, or an individual broker, and you’ll get their registration history, the firms they’ve worked at, the exams they’ve passed, and – most importantly – any disclosures: customer complaints, regulatory actions, bankruptcies, criminal charges, terminations for cause.

It’s free, anonymous, and takes about thirty seconds. Before you hand any firm money, look them up. If you find a clean record at a well-known brokerage like Betterment Securities or Wealthfront Brokerage, that’s the expected baseline. If you find a wall of disclosures at a firm you’ve never heard of – run.

FINRA vs. the SEC

FINRA regulates brokers; the SEC regulates the broader securities industry

People mix these up constantly. The short version:

  • The SEC is a federal government agency. It oversees the entire securities industry – exchanges, public companies, investment advisors, mutual funds, the lot. It can bring civil and criminal enforcement actions.

  • FINRA is a private non-profit that focuses specifically on broker-dealers and the people who work for them. It can fine and ban, but it can’t put anyone in jail. It reports to the SEC.

Most robo-advisors are actually two companies stacked together: a registered investment advisor (regulated by the SEC) plus an affiliated broker-dealer (regulated by FINRA) that holds your assets. Wealthfront Inc. is the advisor; Wealthfront Brokerage LLC is the FINRA-registered broker. Same pattern at most of the major players.

Where FINRA Falls Short

FINRA is not above criticism, and the criticism is mostly fair.

Enforcement activity has dropped substantially over the last decade. Cases brought are near historic lows, fines have shrunk, and the targets tend to be smaller firms doing dumb things rather than larger firms doing systemic things. Senator Elizabeth Warren and others in Congress have pushed back on this trend, arguing that the body in charge of policing Wall Street brokers is being run by Wall Street brokers – which is, when you say it out loud, exactly the structural problem.

There’s also the conflict-of-interest issue baked into the SRO model: FINRA is funded by membership fees from the firms it regulates. Whether that compromises its independence depends on who you ask, but the question doesn’t go away just because the answer is uncomfortable.

What FINRA Means for Robo-Advisor Users

Three practical things:

  • Your money is held at a FINRA-registered broker-dealer. That’s the entity that has custody of your assets, not the app you log into. It’s worth knowing the name (it’ll be on your statements).

  • SIPC protection lives at the broker-dealer level. If the firm fails, SIPC insurance covers up to $500,000 per account ($250,000 cash). This is separate from FDIC, and separate from market losses (which nothing insures).

  • BrokerCheck them before you sign up. If you’re choosing between robo-advisors, our comparison guide covers the major players. But running a BrokerCheck lookup on the underlying broker-dealer takes thirty seconds and tells you something the marketing site won’t.

Frequently Asked Questions

What is FINRA’s primary mission?

FINRA’s stated mission is to protect investors and ensure market integrity by regulating broker-dealers and the people who work for them. In practice, that means writing rules, running licensing exams, monitoring trading, and bringing enforcement actions when brokers misbehave.

How does FINRA differ from the SEC?

The SEC is a federal agency that regulates the whole securities industry and can bring criminal cases. FINRA is a private non-profit that focuses specifically on brokers and broker-dealers, can fine and ban, but can’t prosecute crimes. FINRA reports to the SEC.

What are FINRA’s main functions?

Writing and enforcing rules for broker-dealers, administering licensing exams (Series 7, 63, 65, 66, etc.), monitoring market activity for fraud and manipulation, and running BrokerCheck.

How does FINRA protect investors?

Mostly by setting and enforcing conduct rules for brokers, recovering restitution when they’re broken, and making disciplinary history publicly searchable through BrokerCheck. The disclosure piece is the most directly useful to retail investors.

Is my robo-advisor regulated by FINRA?

The broker-dealer behind your robo-advisor is. The advisor entity itself (the company picking your portfolio) is regulated by the SEC as a registered investment advisor. They’re usually two separate corporate entities under the same parent – Wealthfront Inc. and Wealthfront Brokerage LLC, for example.

What criticisms does FINRA face?

That enforcement activity has dropped sharply, that it focuses on smaller firms rather than systemic issues at larger ones, and that being funded by the firms it regulates is a structural conflict of interest. None of these criticisms are new and none have been resolved.
