Financial Advisor Negligence: FINRA Arbitration, the Six-Year Eligibility Rule, and What a Claim Recovers
An account that lost money is not a claim. An account that lost money because the person handling it ignored the risk you described, traded it for the commissions, or put your retirement into one position is a different matter, and that question usually gets answered outside a courthouse. This guide covers what counts as financial advisor or broker negligence, why the account agreement sends the dispute to FINRA arbitration, how the two deadlines work, and how a claim is measured.
Quick answer
Financial advisor negligence is a failure to handle an account with the care the governing conduct standard requires, causing a loss the market alone does not explain. Most customer claims against a brokerage firm go to FINRA arbitration rather than court because the account agreement says so, and FINRA Rule 12206 makes a claim ineligible once six years have passed from the event that gave rise to it. Claims of $50,000 or less are decided by a single arbitrator on the documents under FINRA Rule 12800, and claims above $100,000 go to three arbitrators under Rule 12401. A claim is measured by the loss the conduct caused, not by what the account was worth at its peak.

What counts as financial advisor negligence, and what does not
Investing loses money sometimes, and no conduct rule promises otherwise. A claim starts where the loss traces to how the account was handled rather than to the market: a portfolio built for a different tolerance for risk and a different time horizon, a position sized so that one bad quarter takes the account down, trading whose frequency serves the commissions, or a product sold on a description of its risk that was not accurate.
Two rulebooks answer what care was owed, and which applies depends on the capacity the person was acting in. A registered investment adviser, typically paid a fee on assets, owes its client a fiduciary duty under the Investment Advisers Act, which the SEC set out in its 2019 interpretation of the standard of conduct for investment advisers. A broker-dealer and its registered representatives, typically paid per transaction, are governed when they recommend a securities transaction or strategy to a retail customer by SEA Rule 15l-1, the SEC conduct standard known as Reg BI. Many people hold both registrations and switch capacity by account, which is why a claim starts with the account agreement rather than the business card.
What is not a claim: a diversified portfolio that fell with the index, a position you chose over written advice, a disclosed risk you accepted, or a result you dislike in hindsight. Conduct is judged on what was known at the time of the recommendation, and the question is always whether a specific breach caused a specific, measurable loss.
The conduct standards a claim is built on
A statement of claim names the standard it says was breached. These four are the ones customer claims are usually built from, and the first two are mutually exclusive by rule.
Fiduciary duty, for investment advisers
An investment adviser owes a duty of care and a duty of loyalty, which the SEC describes in its 2019 interpretation as applying to the whole relationship rather than transaction by transaction. Care covers the advice, the fit of the strategy, and ongoing monitoring where the relationship calls for it. Loyalty requires the adviser not to put its own interest ahead of the client’s and to disclose conflicts fully and fairly.
Reg BI, for broker-dealer recommendations to retail customers
SEA Rule 15l-1 requires a broker, dealer or associated person recommending a securities transaction or strategy to a retail customer to act in that customer’s interest at the time of the recommendation, without placing its own financial interest ahead of the customer’s. It is satisfied only through four obligations: disclosure of the relationship, fees and conflicts; care in understanding risks, rewards and costs; addressing conflicts; and written compliance policies.
FINRA Rule 2111 suitability, for what Reg BI does not cover
Rule 2111 requires a reasonable basis to believe a recommendation is suitable given the customer’s investment profile: age, other investments, financial situation, tax status, objectives, experience, time horizon, liquidity needs and risk tolerance. Supplementary Material .08 switches the rule off for any recommendation subject to Reg BI, effective June 30, 2020, so 2111 now reaches older conduct and customers Reg BI does not cover.
Supervision, which is the firm’s own duty
FINRA Rule 3110 requires a brokerage firm to maintain a supervisory system reasonably designed to achieve compliance, including written procedures and review of its representatives’ activity. A failure-to-supervise claim says the firm had the trade blotters, the exception reports and the complaints in front of it and did nothing. It matters because the firm, not the representative, has the assets to satisfy an award.
The six claims customers actually bring
Most statements of claim combine several of these. They are less separate legal theories than separate fact patterns, and one account often supports more than one.
Unsuitability
The strategy or product did not fit the profile: a retiree drawing income placed in illiquid or leveraged products, a conservative investor put into concentrated equity, a short horizon invested as though it were long. The recommendation was wrong for this person, whatever it was for anyone else.
Churning and excessive trading
Trading whose volume serves the commissions rather than the account. The usual measures are the turnover rate (how many times the portfolio was replaced in a year) and the cost-equity ratio (what the account had to earn just to break even on costs), with in-and-out trading as a supporting signal.
Unauthorized trading
Trades placed in a non-discretionary account without approval. This one is documented rather than argued: the confirmations and the agreement show whether discretion was granted in writing, and the claim turns on whether the customer ratified the trade by staying silent.
Misrepresentation and omission
A product described inaccurately, or a material risk never mentioned. Omission claims are often stronger than affirmative misstatements because the proof is documentary: what the firm’s own materials said the risk was, next to what the customer was told.
Over-concentration and failure to diversify
One position, sector or employer’s stock carrying so much of the account that an ordinary decline becomes a catastrophic one. Common where an employee’s savings and salary already depended on the same company.
Failure to supervise
The Rule 3110 claim against the firm, pleaded alongside the conduct claim, particularly where the representative has left the industry or has other complaints on record.
FINRA arbitration or court: the agreement usually decides
Nearly every brokerage account agreement contains a pre-dispute arbitration clause, and the Federal Arbitration Act makes it enforceable, so a customer dispute with a FINRA-registered brokerage firm goes to FINRA Dispute Resolution Services rather than to a judge and jury. The customer files a statement of claim, the firm answers, the parties select arbitrators from lists FINRA sends, documents are exchanged, and the case is decided at a hearing or on the papers. There is no jury and no ordinary appeal on the merits, and the award is enforceable in court.
The size of the claim sets the shape of the case. Under Rule 12800, an arbitration involving $50,000 or less, exclusive of interest and expenses, is decided on the pleadings and submitted materials unless the customer asks for a hearing, and Rule 12401 gives those claims a single arbitrator. Above $50,000 but not more than $100,000, one arbitrator hears it unless the parties agree in writing to three; above $100,000, or where the amount is unspecified, three arbitrators hear it unless they agree in writing to one. Awards do not come with reasoning: under Rule 12904 the arbitrators write an explained decision only if the parties jointly request one before the prehearing exchange, and even then it states general reasons rather than damage calculations.
Court is still possible. A registered investment adviser’s client agreement may contain no arbitration clause, in which case a fiduciary-duty claim is an ordinary civil lawsuit, and state securities acts (blue sky laws) give investors statutory causes of action with their own remedies and deadlines. A claim dismissed in arbitration as ineligible under the six-year rule may still be brought in court if the state deadline allows, because Rule 12206(b) says a dismissal on eligibility grounds does not prohibit pursuing the claim there.
Two clocks: the six-year eligibility rule and your state’s filing deadline
FINRA Rule 12206 provides that no claim is eligible for submission to arbitration once six years have elapsed from the occurrence or event giving rise to it, and the arbitrators decide any question about eligibility. That limit is not a statute of limitations and the rule says so: it does not extend any state deadline, and a state deadline can expire long before the six years run out. Filing in arbitration tolls the court deadline while FINRA retains jurisdiction, and filing in court stops the six-year clock while the court retains the matter, but neither revives a period already ended. The chart below shows the general professional-malpractice deadline our database records for each of the 51 jurisdictions, which is the one that would apply to a court claim.
Work backward from the earliest date any clock could have started and treat the shortest period as the real one. The hard part is the start, not the length: the occurrence or event is often the purchase or the recommendation rather than the month the statements showed the damage, and states differ on whether their period runs from the conduct or from when a reasonable investor would have discovered it. Which date governs your facts is a question for a licensed attorney in your state, asked well before the earliest deadline could pass.

This is the deadline for filing in court, not the FINRA eligibility limit. Rule 12206 separately makes a claim ineligible for arbitration six years after the occurrence or event giving rise to it, and does not extend any state period. Many states measure their own period from when the investor discovered or should have discovered the conduct; confirm the length and the start date with a licensed attorney in the state.
What a financial advisor negligence claim recovers
There is no formula, and the arbitrators are not required to explain the number they reach. Claimants present a measure of loss and support it with an expert analysis of the account. These are the measures that get argued.
Net out-of-pocket loss
What went into the account or the position, less what came out and what remains, adjusted for deposits and withdrawals. It is the easiest to prove from statements alone and the floor most claims start from, but it treats the money as though it would otherwise have sat still.
Market-adjusted damages
Out-of-pocket loss plus what the same money would have earned over the same period in a suitable allocation, usually a broad index or a conservative blend fitted to the customer’s stated profile. This captures the point of the claim: the harm was not only the dollars lost but the years the money spent in the wrong place.
The well-managed-account measure
A closer variant that reconstructs what the account itself would have been worth if handled properly from the date of the breach, instead of comparing it to an index. Used where the account had a defined mandate, and the most document-intensive of the three.
Commissions, fees and interest
Costs charged on the disputed activity are a separate item and the cleanest number in the case, because the firm’s own records produce them. Churning claims often lead with it. Arbitrators may also award interest and allocate forum fees.
Why punitive damages are not the frame
Punitive damages require conduct well beyond carelessness, such as fraud or conscious disregard of the customer’s rights, and most negligence claims are neither. Build the claim around compensatory loss.
Arbitration is document-driven, and most of the documents that decide a case were created at the start of the relationship. Assemble them before anyone writes a statement of claim.
1
Collect the account paperwork
Statements for the entire relationship, trade confirmations, and the account agreement. The first two produce the position history, the deposits and withdrawals, the commissions and the turnover, and no damages analysis runs without them. The agreement tells you whether the dispute goes to FINRA arbitration or to court and whether discretion was ever granted in writing.
2
Get the new-account form and the risk profile it recorded
The single most important document in most claims. It records what the firm wrote down about your objectives, time horizon, risk tolerance, net worth and investment experience when the relationship began. Where it says conservative and income while the account holds leveraged or concentrated positions, the unsuitability claim is made out of the firm’s own paperwork.
3
Gather the communications
Emails, texts, letters and meeting notes describing the strategy or a product’s risk. What you were told, next to what the firm’s own materials said, is the heart of a misrepresentation or omission claim. Ask in writing that the firm preserve its side.
4
Get an expert analysis of the account
A securities damages expert runs the numbers that turn a bad result into a measured claim: turnover rate, cost-equity ratio, concentration by position and sector, total commissions, and the damages comparison. Doing this before filing also tests the case honestly, because an account that underperformed without any breach will show it.
5
File the statement of claim, watching both clocks
It names the parties, states the conduct and the standards breached, and asks for a specific sum, which sets the number of arbitrators and whether the simplified procedure applies. File before the earlier of the six-year eligibility limit and your state deadline.
What the other side will argue
The firm’s answer is predictable, and each item is easier to handle before filing than after.
The market caused the loss, not the conduct
The most common defense, and the reason the damages comparison matters. If a comparable suitable portfolio fell by a similar amount over the same period, causation gets harder.
You knew, and you accepted it
The prospectus, the risk disclosures, the signed acknowledgments and the profile form, plus an argument that the position was unsolicited. Where that paperwork describes what actually happened, the claim narrows to what it did not say.
You ratified the trades
A statement arrived, you read it, and you did nothing for months. This is the standard answer to unauthorized-trading and churning claims, and why the date of your first written complaint carries weight.
The claim is out of time
A motion to dismiss under Rule 12206 argues that more than six years have passed since the occurrence or event; in court the state statute of limitations is raised instead. Both turn on when the clock started.
What the numbers look like
The frame is the loss the conduct caused, measured against what a suitable allocation would have done, plus the costs charged along the way. The figures below are invented to show the structure.
Start with the loss the conduct caused
Not the account’s peak value and not the total decline, but what was lost from the date of the breach, net of deposits and withdrawals.
Add what a suitable allocation would have produced
This needs an expert and is the step the firm contests hardest, because the comparison chosen moves the number more than anything else.
Add the costs charged on the disputed activity
Commissions, markups and fees on the trades at issue come from the firm’s own records, which makes them the least arguable figure.
Leave punitive damages and the award’s reasoning out of your planning
They need conduct beyond carelessness, and under Rule 12904 you get no written explanation of the award unless both sides asked for one in advance.

Nothing here needs a decision today except two things: put the account statements and the new-account form in one place, and write down the earliest date either clock could have started. A licensed attorney in your state confirms which forum and which deadline apply. Nothing on this page is legal or investment advice.

Handling an account without the care the governing standard requires, causing a measurable loss. The recurring fact patterns are unsuitable recommendations, excessive trading, unauthorized trades, misrepresenting or omitting a material risk, over-concentration, and a firm that failed to supervise. A portfolio that simply fell with the market is not negligence.
Almost every brokerage account agreement contains an enforceable pre-dispute arbitration clause, so a customer dispute with a FINRA-registered brokerage firm normally goes to FINRA Dispute Resolution Services. Court remains possible where no such clause applies, most often with a registered investment adviser whose client agreement has none, and state securities acts give investors their own causes of action.
Two clocks run at once. FINRA Rule 12206 makes a claim ineligible for arbitration once six years have elapsed from the occurrence or event giving rise to it, and your state statute of limitations separately governs a court claim and can expire much sooner. The rule does not extend any state deadline, so work from whichever ends first and check the chart above.
A registered investment adviser owes a fiduciary duty of care and loyalty covering the whole relationship, as the SEC set out in its 2019 interpretation. A broker-dealer recommending a securities transaction or strategy to a retail customer is governed by SEA Rule 15l-1 (Reg BI), which applies at the time of each recommendation through four obligations: disclosure, care, conflicts of interest and compliance. Which applies turns on the capacity the person acted in, not their title.
Not to recommendations Reg BI covers. Rule 2111 Supplementary Material .08 states that the rule does not apply to a recommendation subject to SEA Rule 15l-1, effective June 30, 2020. Rule 2111 still governs conduct before that date and recommendations outside Reg BI’s scope, and its reasonable-basis, customer-specific and quantitative suitability vocabulary is still what arbitrators use.
Through the numbers in your own statements rather than anyone’s intent. The standard measures are the turnover rate, how many times the portfolio was replaced over a year, and the cost-equity ratio, what the account had to earn simply to cover its costs. FINRA Rule 2111 calls this quantitative suitability, and Reg BI’s care obligation reaches a series of recommendations that is excessive even where each looks defensible alone.
There is no standard figure. Claims are measured by net out-of-pocket loss, by market-adjusted damages that add what the same money would have earned in a suitable allocation, or by reconstructing what a properly handled account would have been worth, plus the commissions and fees charged on the disputed activity. Arbitrators may also award interest and allocate forum fees.
The size of the claim sets the shape. Under Rule 12800 a claim of $50,000 or less is decided on the parties’ submitted materials unless the customer requests a hearing, and Rule 12401 gives it one arbitrator; above $50,000 but not more than $100,000 one arbitrator hears it unless both sides agree in writing to three; above $100,000, or where the amount is unspecified, three arbitrators hear it unless both agree to one. Under Rule 12904 the award states a result without reasoning unless the parties jointly requested an explained decision in advance.
