Broker Misconduct: 10 Common FINRA Violations to Know

Broker Misconduct: 10 Common FINRA Violations to Know

Key Takeaway: Broker misconduct isn’t random — it follows predictable patterns. FINRA’s enforcement actions and customer complaints consistently involve the same ten types of violations, from unsuitable recommendations to outright theft. If your broker committed any of these violations, you may have a FINRA arbitration claim to recover your losses.

When you trust a broker with your investments, you expect them to follow the rules. Most do. But the ones who don’t tend to violate the same rules in the same ways, year after year. FINRA’s enforcement data shows clear patterns — and knowing these patterns can help you spot misconduct in your own account.

Here are the 10 most common types of broker misconduct that FINRA sees, what rules they violate, how to spot them, and whether they give you a claim for recovery.

1. Unsuitable Recommendations

Unsuitability occurs when a broker recommends an investment or strategy that is not appropriate for the customer’s investment profile, risk tolerance, or financial objectives.

FINRA Rule 2111 requires brokers to have a reasonable basis to believe that a recommendation is suitable for a particular customer. This means the investment must make sense for someone with your age, income, investment experience, risk tolerance, and goals.

How to spot it: You’re sold a speculative biotech stock when you asked for conservative income investments. You’re placed in a high-risk options strategy when you have no options experience. You’re recommended a 7-year illiquid product when you told your broker you might need access to your money within two years.

Does it give you a claim? Yes. Unsuitability is one of the most common grounds for FINRA arbitration claims. If you can show that the investment was inappropriate for your profile and caused you losses, you may recover. See our detailed post on When Can You Sue Your Financial Advisor? for more on the claims process.

2. Churning

Churning is excessive trading in a customer’s account for the purpose of generating commissions for the broker.

FINRA Rule 2111 and Rule 2210 prohibit brokers from trading accounts in a manner that is excessive in size or frequency given the customer’s objectives. Churning typically involves a high turnover rate and a high cost-to-equity ratio — meaning the commissions eat up a significant portion of the account’s value.

How to spot it: Your account shows a high volume of trades, many of which seem unnecessary. You notice frequent buying and selling of the same or similar securities. Your commission costs exceed 5–10% of your account’s average annual value. Your broker earns significant commissions while your account underperforms.

Does it give you a claim? Yes. Churning claims require showing that the broker exercised control over the account, the trading was excessive, and the broker acted with intent to generate commissions. Courts and arbitrators often look for a turnover rate above 6 and a cost-to-equity ratio above 17% as indicators of churning.

3. Unauthorized Trading

Unauthorized trading occurs when a broker executes trades in a customer’s account without the customer’s prior consent or authorization.

FINRA Rule 3260 and Rule 2111 require brokers to obtain customer authorization before executing trades in non-discretionary accounts. In discretionary accounts, the broker must have written authorization and the firm must have accepted the account as discretionary.

How to spot it: You see trades on your account statement that you didn’t approve. Your broker bought or sold securities without discussing it with you first. You notice that trade confirmations are for transactions you don’t recall authorizing.

Does it give you a claim? Yes. Unauthorized trading is one of the clearest violations and strongest grounds for a FINRA claim. If your broker made trades you didn’t approve, you may be entitled to rescind the transactions and recover your losses.

4. Misrepresentation and Omission

Misrepresentation occurs when a broker makes false or misleading statements about an investment, and omission occurs when a broker fails to disclose material facts that a reasonable investor would want to know.

FINRA Rule 2020 prohibits brokers from making any untrue statement of a material fact or omitting to state a material fact in connection with the purchase or sale of a security. This is also prohibited under Section 10(b) of the Securities Exchange Act and Rule 10b-5.

How to spot it: Your broker told you an investment was “guaranteed” or “can’t lose money” when it carried real risk. Your broker failed to disclose surrender penalties, high fees, or liquidity restrictions. Your broker exaggerated the investment’s historical returns or future prospects.

Does it give you a claim? Yes. Misrepresentation and omission claims are common and can be powerful. You need to show that the statement or omission was material, that you relied on it, and that it caused your losses.

5. Selling Away

Selling away occurs when a broker sells securities that are not approved or offered by their firm, without the firm’s knowledge or approval.

FINRA Rule 3280 requires brokers to provide written notice to their firm before engaging in any private securities transaction. Selling away typically involves brokers selling promissory notes, private placements, or other unregistered securities on the side.

How to spot it: Your broker recommended an investment that doesn’t appear on your regular account statements. The investment was handled through a separate entity or a different broker-dealer. You received documents or statements from a company other than your broker’s firm.

Does it give you a claim? Yes. You may have claims against both the broker and the firm. The broker violated FINRA rules by selling away, and the firm may be liable for failing to supervise. Many selling away cases involve investments that turned out to be fraudulent or worthless, resulting in total losses for the investor.

6. Failure to Supervise

Failure to supervise occurs when a brokerage firm does not adequately oversee the activities of its brokers, allowing misconduct to go undetected or unaddressed.

FINRA Rule 3110 requires every firm to establish and maintain a system of supervision over its associated persons. This includes written supervisory procedures, designation of supervisors, review of transactions, and investigation of red flags.

How to spot it: Your broker’s misconduct was obvious or should have been caught by routine review. The firm failed to respond to complaints or red flags. The broker had a history of violations that the firm ignored. There were no meaningful compliance reviews of your account.

Does it give you a claim? Yes — and the firm may be your most important target. Under FINRA rules, a firm is responsible for the misconduct of its brokers when its supervisory system was deficient. Firms have deeper pockets than individual brokers, so a failure-to-supervise claim can significantly increase your potential recovery. See our post on When Can You Sue Your Financial Advisor? for more on how to bring a claim against the firm.

7. Unauthorized Outside Business Activities

Unauthorized outside business activities occur when a broker engages in business activities outside the scope of their firm without providing required notice or obtaining approval.

FINRA Rule 3270 requires brokers to provide written notice to their firm before engaging in any outside business activity. This includes serving as an officer, director, or employee of another company, or engaging in any business activity for compensation outside the firm.

How to spot it: Your broker asked you to invest in a business they own or operate on the side. Your broker recommended an insurance product or real estate investment outside the firm. Your broker has financial interests in the investments they’re recommending that aren’t disclosed.

Does it give you a claim? Potentially. If the outside activity involved selling you an investment or providing advice for compensation without the firm’s knowledge, you may have claims against the broker and possibly the firm. These cases often overlap with selling away.

Call 1-888-885-7162 or [contact us online] if you believe your broker engaged in unauthorized outside business activities at your expense. Our attorneys have 95 years of experience and a 98% success rate.

8. Conversion and Theft

Conversion occurs when a broker improperly takes or uses a customer’s funds or securities for their own benefit. Theft involves the outright stealing of customer assets.

Conversion and theft are among the most serious broker violations. They violate FINRA Rule 2150 (prohibiting improper use of customer securities), FINRA Rule 2020 (fraudulent conduct), and often state and federal criminal laws.

How to spot it: Money is missing from your account without explanation. Your broker asked you to write a check to them personally or to an entity other than their firm. You received statements showing withdrawals or transfers you didn’t authorize. Your broker borrowed money from you or used your assets as collateral.

Does it give you a claim? Yes — and possibly criminal charges as well. Conversion and theft are clear violations that almost always support a FINRA arbitration claim. FINRA also refers these cases to law enforcement, and the broker may face criminal prosecution in addition to civil liability.

9. Excessive Concentration

Excessive concentration occurs when a broker over-concentrates a customer’s portfolio in a single security, sector, or asset class, creating unreasonable risk.

While FINRA Rule 2111 doesn’t explicitly mention concentration, it requires brokers to consider the customer’s entire portfolio when making recommendations. Over-concentrating a portfolio can violate the suitability standard, especially for conservative investors.

How to spot it: A single stock or sector makes up more than 20–30% of your portfolio. Your broker recommended putting a large percentage of your assets into one investment. Your portfolio is heavily concentrated in the broker’s firm’s own products. You asked for diversification but ended up concentrated in one area.

Does it give you a claim? Potentially. If the concentration was unsuitable for your risk profile and investment objectives, and it resulted in disproportionate losses, you may have a claim. Concentration claims are particularly strong when the broker recommended the concentrated position against the customer’s stated preference for diversification.

If your portfolio was over-concentrated and you suffered losses, call 1-888-885-7162 or [contact us online] for a free consultation.

10. Switching and Replacement

Switching or replacement occurs when a broker recommends that a customer sell one investment and replace it with another, primarily to generate a new commission.

FINRA Rule 2111 requires brokers to have a reasonable basis to believe that any recommended transaction — including a switch — is suitable for the customer. Unnecessary switches that serve the broker’s interest rather than the customer’s violate this rule.

How to spot it: Your broker recommended selling an existing investment to buy a similar one. You were moved from one annuity to another with no clear improvement. You incurred surrender penalties on the old product and paid new commissions on the replacement. The switch didn’t meaningfully change your investment strategy or improve your position.

Does it give you a claim? Yes. Unnecessary switching is a well-recognized form of broker misconduct. If the switch didn’t benefit you and was done to generate a commission, you may recover the surrender penalties, the new commissions, and any investment losses caused by the switch. See our detailed post on Replacement and Switching: When Your Broker Sells You a New Product to Earn a Commission for a full analysis.

What to Do If You Spot These Red Flags

If you recognize any of these patterns in your own account, take these steps immediately:

1. Request a complete copy of your account records. Under FINRA Rule 4510 and SEC Rule 17a-4, your broker must maintain and make available your account records, including statements, trade confirmations, and correspondence.

2. Preserve all communications. Save emails, text messages, letters, and notes from phone calls with your broker. These can be critical evidence.

3. Don’t confront your broker directly. Doing so may give them the opportunity to alter records, fabricate justifications, or take other steps to conceal the misconduct.

4. File a complaint with FINRA. You can file a complaint through FINRA’s online complaint center. This creates a formal record and may trigger an investigation.

5. Consult an investment fraud attorney. An attorney can evaluate your situation, determine whether you have a viable claim, and help you meet all applicable deadlines.

The most important step is acting promptly. FINRA’s six-year rule and state statutes of limitations impose strict deadlines. If you wait too long, you may lose the right to recover regardless of how clear the misconduct is.

Frequently Asked Questions

How common is broker misconduct?

FINRA receives approximately 3,000 to 4,000 customer complaints per year, and brokers are expelled from the industry at a rate of roughly 300 to 500 per year for various violations. The most common complaints involve unsuitability, misrepresentation, and unauthorized trading. However, many instances of misconduct go unreported because investors don’t recognize the signs.

Can I recover my losses if my broker committed one of these violations?

You may be able to recover your losses through FINRA arbitration if you can show that the broker’s violation caused your financial harm. The strength of your claim depends on the type of violation, the evidence available, and the applicable deadlines. An attorney can evaluate your specific situation. Call 1-888-885-7162 for a free consultation.

Does my broker’s firm share liability for the broker’s misconduct?

In many cases, yes. Under FINRA Rule 3110, firms must supervise their brokers, and they can be held liable for failing to detect or prevent misconduct. Firms may also be held vicariously liable for their brokers’ violations under principles of respondeat superior. This is important because firms typically have greater financial resources than individual brokers. For more on firm liability, see our post on When Can You Sue Your Financial Advisor?.

What is the difference between suitability and fiduciary duty?

Suitability requires a broker to recommend investments that are appropriate for your profile, while fiduciary duty requires an advisor to act in your best interest at all times. Brokers are held to the suitability and Reg BI standard; RIAs are held to the fiduciary standard. The fiduciary standard is significantly more protective. For a full explanation, see Fiduciary Duty vs. Suitability: What Your Financial Advisor Owes You.

How long do I have to file a claim?

Most claims must be filed within 2 to 6 years, depending on the state and the type of claim. FINRA also imposes an absolute six-year deadline from the date of the events giving rise to the dispute. Missing these deadlines can permanently bar your claim. It’s critical to consult an attorney as soon as you suspect misconduct.

What if my losses were caused by a market downturn, not broker misconduct?

Not every investment loss is caused by broker misconduct. If your broker made suitable recommendations and the market declined, you may not have a claim. However, if the broker’s misconduct — such as unsuitable recommendations, excessive concentration, or churning — made your losses worse than they would have been with proper management, you may still have a valid claim. An attorney can help you distinguish between market losses and misconduct-related losses.
