The most common types of stock broker fraud include unsuitable investment recommendations, unauthorized trading, churning, misrepresentation, and failure to supervise.
Broker fraud occurs when a financial professional violates securities rules or their duties to you and causes financial losses. It can involve deception, unauthorized trades, unsuitable recommendations, excessive trading, conflicts of interest, or negligence.
If you’re an investor who’s been the victim of investment fraud at the hands of a broker who you thought you could trust, we understand how devastating this situation can be. Don’t worry, you may still have options for recovering your losses through a settlement. But the outcome still depends on the facts of your case.
Our investment fraud lawyer team will walk you through the nine common types of broker fraud and misconduct, the warning signs to watch for, and your options for recovering losses.
If you believe you’ve been the victim of broker misconduct, contact us immediately. We can help you recover your losses.

1. Unsuitable Investment Recommendations
Unsuitable investment recommendations occur when a broker recommends securities that conflict with your financial profile, objectives, or ability to tolerate risk.
Before recommending an investment, a broker should understand your age, income, financial needs, investment experience, risk tolerance, time horizon, and goals. If preserving retirement savings is your priority, for example, those instructions should influence what your broker recommends.
A retiree living on fixed income generally should not be placed into a concentrated portfolio of speculative equities, leveraged products, or futures without a sound basis.
Now that you know what makes a recommendation potentially unsuitable, you should understand the rules governing it. FINRA (Financial Industry Regulatory Authority) Rule 2111 historically established suitability obligations, while Regulation Best Interest requires broker-dealers to act in a retail customer’s best interest when making recommendations.
2. Misrepresentation and Omission of Material Facts
Misrepresentation occurs when a broker gives you false or misleading information, while omission occurs when the broker leaves out information you needed to make an informed decision.
Material information may include commissions, surrender charges, liquidity restrictions, conflicts of interest, volatility, or potential losses. Brokers cannot present only the benefits while concealing significant risks.
Another thing you must understand is that recommendations need a reasonable factual basis, which means unsupported promises and exaggerated projections cannot replace accurate information about an investment.
Claims involving guaranteed profits, nonexistent risks, or supposed inside information should raise immediate concerns. These statements may constitute misrepresentation rather than harmless sales enthusiasm.
3. Unauthorized Trading
Unauthorized trading occurs when a broker buys or sells securities in your account without obtaining the required permission.
In a nondiscretionary account, your broker generally needs authorization before executing a trade. Different rules apply when you have properly granted discretionary authority allowing certain transactions without approval each time.
Keep in mind that your approval applies to the specific transaction you agreed to. So, if you approve the purchase of one stock, that does not give your broker permission to make another trade later without your approval.
Review trade confirmations and account statements against your own records. Transactions you do not recognize may indicate that your broker has been trading without your authorization.
4. Churning and Excessive Trading
Sometimes an investment account loses money because the account was traded so frequently that commissions, fees, and other costs consumed the investor’s capital.
Churning occurs when a broker exercises control over an account and engages in excessive trading primarily to generate compensation. Individual trades may appear legitimate, while the overall volume and frequency reveal the misconduct.
Another factor you need to understand is that arbitrators can examine measurements such as turnover ratios and cost-to-equity ratios to determine whether trading was excessive.
A churning claim generally considers the broker’s control over the account, excessive trading relative to the investor’s objectives, and wrongful intent. If repeated trading generated substantial fees while your account declined, you may have grounds to investigate further.
5. Overconcentration and Failure to Diversify
Overconcentration happens when too much of your portfolio is exposed to a single security, company, industry, or other closely related source of risk.
Diversification across companies, sectors, and asset classes helps reduce the damage caused when one investment or part of the market performs poorly.
If you want to see where your portfolio may be overexposed, look at how much you have invested in one company or industry. Too much in your employer’s stock or one industry can leave your account vulnerable to a downturn.
Failure-to-diversify claims often follow major stock or sector collapses. A broker may face liability when they recommend or maintain a concentrated position that conflicts with a customer’s objectives and financial circumstances.
6. Breach of Fiduciary Duty
A breach of fiduciary duty can occur when a financial professional who owes you fiduciary obligations puts their interests ahead of yours or otherwise violates those duties.
Investment advisers generally owe fiduciary duties of care and loyalty, while broker-dealers making recommendations to retail customers are subject to Regulation Best Interest and other securities rules.
Pay attention to how your financial professional was paid. Undisclosed compensation, self-dealing, hidden conflicts, or recommendations that favor them may point to misconduct.
Our lawyers have handled these cases and have deep experience representing investors in claims involving conflicts of interest and fiduciary duties. We can review your case and explain your legal options.
Depending on the relationship and applicable law, violating a duty owed to an investor may support a claim when that violation causes financial harm.
7. Unlicensed Brokers and Unregistered Securities
Unlicensed brokers and improperly offered unregistered securities are major warning signs that an investment may not be what you were told.
Brokers and brokerage firms generally must satisfy registration requirements, while securities offerings must either be registered or qualify for an exemption. An unregistered investment is not automatically fraudulent, but you should understand why an exemption applies.
You may check the financial professional’s registration through FINRA BrokerCheck or the SEC’s Investment Adviser Public Disclosure database. It’s better to verify their credentials yourself than rely only on what the broker tells you.
You should also watch for “selling away,” which involves brokers participating in private securities transactions outside their firm’s normal business, potentially including investments the firm never approved.
8. Broker Negligence and Failure to Supervise
You may still have a claim when carelessness rather than intentional fraud caused your investment losses.
Broker negligence can include failing to investigate an investment, disclose important information, understand a client’s financial circumstances, or exercise appropriate care when making recommendations.
Brokerage firms can also be responsible for what happens under their watch. They have their own obligations to supervise registered representatives and maintain systems to identify and prevent misconduct.
A broker does not necessarily need to deliberately defraud you for liability to arise. Negligent conduct that breaches an applicable professional duty and causes financial losses may also support a claim.
9. Fake Brokers and Imposter Scams
We want to help you protect yourself from fake brokers, imposter scams, and identity theft before you send money or provide sensitive financial information.
It is common for fraudsters to impersonate legitimate financial professionals by copying real names, firm logos, registration numbers, websites, and contact information. FINRA even warns investors about broker imposter scams in its official investor guidance.
The best way to protect yourself is to verify the broker through FINRA BrokerCheck before sending money or sharing financial information. Use the contact details listed there rather than any phone numbers, email addresses, or links the person sent you.
Signs of Stockbroker Fraud
Warning signs of fraudulent activity can appear in your account statements, conversations with your broker, or the way an investment is presented to you.
Watch for these seven common red flags:
- Trades appear that you never approved: Any purchase or sale you do not recognize should be investigated immediately.
- Your broker promises unusually high or guaranteed returns: Every investment carries some degree of risk, so promises of easy profits should raise concerns.
- Fees and commissions suddenly increase: Look for charges you cannot explain or repeated transaction costs that steadily reduce your account balance.
- You are pressured to make a quick decision: A broker may create false urgency or tell you an opportunity will disappear if you do not invest immediately.
- Your account is constantly being traded: Frequent buying and selling without a clear investment purpose may indicate churning.
- Getting your money out becomes difficult: Delayed withdrawals, unexplained restrictions, or repeated excuses can signal a larger problem.
- The broker avoids straightforward questions: Be cautious if you cannot get clear answers about your investments, losses, fees, or account activity.
If you recognize one or more of these signs, review your account records carefully and consider having the activity evaluated by an investment fraud attorney.

How to Protect Yourself From Broker Fraud
You can reduce your exposure to broker fraud by verifying credentials, understanding recommendations, and reviewing your account activity regularly.
Before working with a broker, check FINRA BrokerCheck for their employment history, registrations, disclosures, and disciplinary information. Rechecking their record periodically can also reveal disclosures added after you opened your account.
Now that you have verified the person managing your money, maintain your own records. Keep account statements, trade confirmations, emails, agreements, and notes documenting important conversations.
Do not approve an investment you cannot explain in plain language. You should understand how it generates returns, what you could lose, what it costs, and why it belongs in your portfolio.
What to Do If a Broker Defrauded You
If you believe a broker defrauded you, start by documenting what happened and speaking with an investment fraud attorney promptly.
Gather brokerage statements, trade confirmations, account documents, emails, text messages, investment materials, and notes from conversations. These records can help establish what you were told, what you authorized, and how much you lost.
But filing a complaint and recovering your losses are two different things. FINRA, the SEC, or your state securities regulator may investigate the misconduct, but recovering your money may require separate legal action.
Many brokerage agreements contain mandatory arbitration provisions, meaning your claim may need to proceed through FINRA arbitration rather than a traditional court lawsuit.
Cómo funciona el arbitraje FINRA
FINRA arbitration is the primary forum for resolving many disputes between investors and brokerage firms. Of FINRA customer cases closed in 2024, 70% settled between the parties.
The process is generally more streamlined than court litigation. Claims are filed, parties respond, arbitrators are selected, evidence is exchanged, and unresolved disputes may proceed to a hearing.
FINRA also has a six-year eligibility period for claims. Under Rule 12206, a claim generally cannot be submitted once six years have passed from the occurrence or event that gave rise to it.
Separate state or federal statutes of limitations may expire sooner than FINRA’s six-year eligibility period, so suspected misconduct should be reviewed promptly.
