Trading for the Broker, Not the Client

Churning is excessive buying and selling in a client’s account, carried out mainly to generate commissions for the representative rather than to serve the client’s goals. It happens when a professional who controls the account trades far more often than the client’s objectives and risk tolerance can justify.

Churning is one of the classic forms of misconduct in the securities industry. Every trade may look reasonable on its own, but taken together the activity drains the account through commissions and costs while benefiting the person placing the trades.

Regulators treat churning as a violation of suitability, best interest and anti-fraud rules, and it appears regularly on the Series 65. For the full route from the exam to a career as an adviser, our complete guide to how to become an investment adviser representative covers every step.

The Three Elements of Churning

Churning cases usually turn on three questions. First, did the representative control the account, either formally through discretionary authority or in practice because the client routinely followed their recommendations?

Second, was the trading excessive in light of the client’s investment profile, including their objectives, time horizon and risk tolerance? Third, in cases brought under anti-fraud rules, did the representative act with intent to defraud or with reckless disregard for the client’s interests?

Each element matters. A client who directs their own frequent trading is not being churned, while a retiree seeking income whose account is traded heavily by a representative who makes every decision may well be.

How Suitability Rules Address It

Under FINRA Rule 2111, quantitative suitability requires a reasonable basis to believe that a series of recommended transactions is not excessive, even if each trade is suitable on its own. Since 2020, FINRA no longer needs to show that the representative controlled the account to bring a quantitative suitability case.

For retail customers of broker-dealers, Regulation Best Interest also requires recommendations, including a series of trades, to be in the customer’s best interest. Excessive trading that serves the representative fails that test.

Our comparison of FINRA Rule 2090 vs Rule 2111 explains how quantitative suitability fits alongside the other suitability obligations. The Series 65 Exam Preparation course at FRC covers churning as part of the unethical business practices the exam tests.

Churning Compared With Related Practices

Measuring Excessive Trading

Regulators use two main measures. The turnover ratio divides the total cost of purchases over a year by the account’s average equity, showing how many times the portfolio was replaced.

The cost-to-equity ratio divides the year’s commissions and other trading costs by average equity. It shows how much the account would need to earn just to cover its trading costs and break even.

Worked example: an account has average equity of $150,000 and purchases totaling $900,000 over the year, with $36,000 in commissions and costs. Step one: the turnover ratio is $900,000 divided by $150,000, or 6. Step two: the cost-to-equity ratio is $36,000 divided by $150,000, or 24 percent, meaning the account must earn 24 percent a year just to break even.

What the Numbers Suggest

There is no single number that proves churning, because what is excessive depends on the client. But a turnover ratio of 6 or more, or a cost-to-equity ratio above 20 percent, is often cited as a strong sign of excessive trading.

For a conservative client seeking income or preservation of capital, even lower figures can be excessive. A turnover ratio of 2 or 3 might be acceptable for an aggressive, experienced trader but far too high for a retiree.

Worked example: a retiree’s account has average equity of $200,000 and annual trading costs of $50,000. Step one: the cost-to-equity ratio is $50,000 divided by $200,000, or 25 percent. Step two: for a client seeking steady income, needing a 25 percent return just to cover costs is clearly inconsistent with her goals.

Discretionary Accounts and Churning

Discretionary authority makes churning easier, because the representative can trade without asking the client each time. FINRA Rule 3260 requires prior written authorization from the client, acceptance of the account by the firm and review of discretionary trading, and it prohibits excessive transactions in discretionary accounts.

Discretion limited to the time or price of a trade the client has already chosen is treated differently. It generally lasts only until the end of the business day it is given, unless the client provides written instructions otherwise.

For investment advisers, state rules based on the NASAA model generally allow an adviser to exercise discretion based on oral authorization for the first 10 business days, after which written authorization must be obtained. Exercising discretion without proper authorization is itself an unethical practice.

Reverse Churning

Reverse churning is the opposite problem. It happens when a client who trades rarely is placed in a fee-based account, paying an ongoing advisory fee for little or no service.

Worked example: step one, a buy-and-hold investor with $250,000 is moved from a commission account, where she made two trades a year, to an advisory account charging 1.25 percent a year. Step two, she now pays about $3,125 a year for an account that is traded and reviewed almost as rarely as before.

Our comparison of fiduciary standard vs suitability standard explains why choosing the right account type is part of acting in a client’s best interest.

In-and-Out Trading: Worked Example

In-and-out trading means buying a security and selling it again within a short period, often to buy something similar. Each round trip generates commissions without changing the account’s overall strategy.

Worked example: a representative buys $50,000 of a stock for a client, sells it three weeks later and buys a similar stock, repeating the pattern ten times in a year. Step one: each round trip involves a purchase and a sale, so the account trades $50,000 in and out ten times, or $500,000 of purchases in total. Step two: at a combined cost of 1 percent per round trip, the client pays about $5,000 in commissions on a $50,000 position, a 10 percent drag before any gain or loss.

A pattern like this, especially without a clear investment reason for each switch, is exactly what supervisors and regulators look for. The client’s account may hold similar securities at year-end, but it will be smaller because of the costs.

Churning in Advisory Accounts

Churning is most often associated with commission-based brokerage accounts, because more trades mean more pay. In a typical advisory account charged as a percentage of assets, the adviser does not earn more from additional trades, so the incentive to churn is weaker.

That does not mean advisory accounts are immune. Advisers who receive per-trade compensation, share in commissions through an affiliated broker or direct trades to brokers in exchange for soft dollar benefits can still have reasons to trade more than a client needs.

The fiduciary duty applies in every case. An adviser must trade only when it is in the client’s best interest and must disclose any arrangement that rewards it for trading activity.

How Firms Supervise for Churning

Firms use exception reports that flag accounts with high turnover, high commissions relative to account value or frequent in-and-out trades. Supervisors review flagged accounts and contact representatives for explanations.

Many firms also send active account letters to customers whose accounts show heavy trading. These letters ask the customer to confirm that the activity matches their objectives, giving the firm a chance to catch problems early.

Supervision failures are taken seriously. A firm that ignores clear red flags can face its own disciplinary action, in addition to any action against the representative.

Warning Signs of Churning

Frequent in-and-out trading, where securities are bought and sold within short periods, is one of the most common signs. So is a pattern of selling one security to buy a similar one, generating commissions without changing the account’s strategy.

Account statements showing high commissions relative to account value, a representative who places nearly every trade, and trading that does not match the client’s stated objectives are further red flags. Supervisors review exception reports to spot these patterns.

Clients can protect themselves too. Reading trade confirmations and statements, questioning frequent trades and comparing commissions with account growth can reveal churning early, before the costs compound.

Consequences of Churning

Churning can lead to disciplinary action by FINRA or state regulators, including fines, suspensions and bars from the industry. Firms may be required to pay restitution to customers, and supervisors can face action for failing to detect it.

Customers can also bring arbitration claims to recover losses and excess commissions. Because churning cases often involve vulnerable customers, such as retirees, regulators treat them seriously.

For representatives, the reputational damage can end a career. A churning finding appears on BrokerCheck and the Investment Adviser Public Disclosure website, where future clients and employers can see it.

Questions Clients Ask

How can I tell if my account is being churned? Compare the commissions and fees on your statements with the account’s value and growth, and look for frequent trades you did not ask for or do not understand. If costs are high and the strategy keeps changing, ask your representative to explain each trade.

Is a lot of trading always a bad sign? No. Some clients choose an active strategy and understand the costs, but the trading should match what you agreed to and be driven by your goals, not by commissions.

What should I do if I suspect churning? Raise it with the firm’s compliance department or branch manager first. If that does not resolve it, you can contact FINRA or your state securities regulator, and you may have the right to bring an arbitration claim.

The Memory Aid

Remember “control, excess, intent”: the three classic elements of a churning case.

For the ratios, remember “6 and 20”: a turnover ratio of 6 or a cost-to-equity ratio above 20 percent are common warning levels.

For the opposite problem, remember “reverse churning is paying fees for nothing”: inactive clients placed in fee-based accounts.

For discretion, remember “written first for brokers, 10 business days for advisers”: broker-dealers need prior written authorization, while state rules let advisers use oral discretion for up to 10 business days before written authorization is required.

Exam Traps to Avoid

The first trap is assuming each trade must be unsuitable for churning to occur. Churning is about the pattern; each trade can look reasonable while the overall activity is excessive.

The second trap is labeling client-directed frequent trading as churning. If the client controls and directs the trading, it is generally not churning by the representative.

The third trap is thinking only commission accounts raise concerns. Reverse churning affects fee-based accounts. The fourth trap is forgetting that time-and-price discretion generally expires at the end of the business day it is granted.

A Client Scenario

A 70-year-old widow with a $300,000 account relies entirely on her representative, approving every trade he suggests. Over a year, he places dozens of trades, and her statements show commissions of about $60,000.

Her daughter reviews the statements and notices that the account’s value has fallen even though markets rose. The cost-to-equity ratio is about 20 percent, and turnover is far higher than her mother’s goal of steady income could justify.

The family complains to the firm, which reviews the activity, finds excessive trading, compensates the client and reports the matter to regulators. The representative faces disciplinary action, and the firm reviews its supervision of the branch.

Practice Questions to Test Yourself

Question one: What is churning? Excessive trading in a client’s account, mainly to generate commissions, inconsistent with the client’s objectives.

Question two: An account has average equity of $150,000 and purchases of $900,000 in a year. What is the turnover ratio? 6.

Question three: An account has average equity of $200,000 and annual costs of $50,000. What is the cost-to-equity ratio? 25 percent.

Question four: A client directs frequent trades herself. Is this churning by the representative? Generally no, because the client controls the trading.

Question five: What is reverse churning? Placing a client who trades rarely in a fee-based account where they pay ongoing fees for little service.

Turn Ethics Knowledge Into Career Evidence

Firms want representatives who build client wealth, not commissions, and a clear understanding of churning shows exactly that mindset. FRC’s Digital Profile shows employers the courses you are actively studying and the progress you have earned through assessed learning, verified by FRC, and a QR code on your resume takes them straight to it.

The FRC Video Resume lets a hiring manager hear you before the interview. Explaining how you would spot churning on a client’s statement shows the integrity advisory firms look for.

Key Points to Retain

Churning is excessive trading in a client’s account to generate commissions, inconsistent with the client’s investment profile. Cases usually involve control of the account, excessive trading and, under anti-fraud rules, intent or recklessness, while quantitative suitability under FINRA Rule 2111 no longer requires control to be shown.

Regulators measure trading with the turnover ratio and the cost-to-equity ratio, often treating 6 and 20 percent as warning levels, though what is excessive depends on the client. Discretionary accounts require written authorization, time-and-price discretion generally lasts only for the day, and reverse churning in fee-based accounts is the opposite problem.
