FINRA’s Reid & Rudiger Case: Excessive Trading, Reg BI and Broker-Dealer Supervisory Accountability

FINRA’s expulsion of Reid & Rudiger offers practical lessons for broker-dealers, supervisors and compliance officers on excessive trading, Reg BI, churning surveillance and delegated supervisory responsibility.

Executive Summary: Why the Reid & Rudiger Order Matters for Broker-Dealers

FINRA’s Account-Level Supervision Lesson

In short, FINRA’s Reid & Rudiger Order reinforces that broker-dealers should supervise excessive-trading risk at the account level, not merely approve individual transactions. Firms should evaluate cumulative commissions and charges, turnover, holding periods, margin interest, losses, exception reports and prior examination findings as part of a documented supervisory workflow.

FINRA Sanctions: Firm Expulsion, Individual Bars and Supervisor Penalties

On June 17, 2026, FINRA accepted an Offer of Settlement resolving its disciplinary proceeding against Reid & Rudiger LLC, cofounders Edward J. Rudiger Jr. and Clifford R. Reid, and supervisors Marc Harrison and Kelli A. Mezzatesta. FINRA expelled the firm, barred Rudiger and Reid from association with any FINRA member in all capacities, and imposed principal suspensions, fines and supervision-related continuing education on Harrison and Mezzatesta. The sanctions were significant, but the broader lesson is supervisory: excessive-trading risk can migrate from an individual broker issue into a firm-wide problem involving surveillance design, compensation incentives, supervisory follow-through and senior-management accountability.

Excessive Trading Metrics: Market Timing, Cost-to-Equity and Turnover

FINRA found that, from February 2018 through October 2023, Rudiger and Reid recommended a high-volume, high-cost market-timing strategy in 20 customer accounts. The strategy repeatedly moved customers in and out of large equity positions, frequently using margin. According to the Order, the affected accounts incurred nearly $2.2 million in trading costs, including almost $2 million in commissions, and sustained more than $2.7 million in losses. In the most extreme accounts, annualized cost-to-equity ratios reached 111.59% and annualized turnover reached 17.33. FINRA’s point was not that any single metric decided the case; it was that the cumulative economics of the trading made the strategy extraordinarily difficult, and in some accounts virtually impossible, to overcome.

Reg BI Transition: Suitability, Care Obligation and Churning Standards

The case also spans an important regulatory transition. FINRA evaluated conduct before June 30, 2020 under Rule 2111’s quantitative suitability framework. It analyzed recommendations to retail customers after that date under Regulation Best Interest, including the Care Obligation’s requirement that a series of recommendations, taken together, not be excessive and remain in the customer’s best interest. FINRA separately pursued churning theories under Exchange Act Section 10(b), Rule 10b-5 and FINRA Rule 2020, which require additional proof of control and scienter.

Broker-Dealer Takeaways: Surveillance Design, Delegation and CCO Liability

For member firms, the practical lesson is that transaction-by-transaction review is not enough. A reasonably designed supervisory system should identify patterns that emerge only over time, including escalating turnover, cumulative commissions and charges, short holding periods, margin usage, recurring in-and-out trading and customer losses. The Order is also a useful reminder that CCO liability turns on delegated supervisory responsibility, not title. When a firm assigns supervisory functions to compliance personnel, that allocation should be deliberate, clearly documented, and supported by tools that allow those responsibilities to be discharged reasonably.

Key Takeaways for Broker-Dealers: Excessive Trading, Reg BI and Supervision

The Reid & Rudiger Order points to several practical lessons for broker-dealers reviewing excessive-trading surveillance, Reg BI compliance, churning risk, exception-report workflows and supervisory delegation.

• Account economics matter as much as the individual securities being recommended. A series of recommendations may present a Reg BI or suitability problem even when each security, viewed individually, is not facially inappropriate. Firms should be able to evaluate the cumulative burden of commissions, markups or markdowns, service charges, margin interest, turnover, holding periods and losses.
• Reg BI changed the excessive-trading analysis for retail customers in an important respect. Under the Care Obligation, FINRA does not need to establish actual or de facto control over the account to challenge a series of recommendations as excessive. That differs from the former quantitative suitability framework and from a traditional churning theory.
• Churning remains a separate fraud theory. FINRA described churning as requiring control, excessive trading and scienter. The practical consequence is that the same trading pattern can support different theories depending on the evidence: a Reg BI excessive-trading case without proof of control, and a churning case where control and scienter are also present.
• Exception reports do not reduce risk merely because they exist. FINRA repeatedly emphasized that the clearing firm made turnover and cost-to-equity reports available, yet the firm did not obtain and use them. Supervisory technology has value only when firms understand what it can detect, assign responsibility for review and follow through on the exceptions it produces.
• Prior examination findings change the enforcement posture. FINRA identified excessive-trading surveillance weaknesses during a 2018 examination. Although the firm revised its WSPs, FINRA found that the underlying supervisory problem persisted. That history matters because a later enforcement case involving the same issue is likely to be viewed through a remediation and recidivism lens, rather than as an isolated first occurrence.
• Supervisory responsibility follows delegation, not job title. FINRA Regulatory Notice 22-10 makes clear that a CCO is not a Rule 3110 supervisor merely by virtue of the title. Here, however, the WSPs assigned Mezzatesta direct supervisory duties, including pre-trade and blotter review and responsibility for obtaining exception reports. Those assignments, not the CCO title alone, drove the analysis.
• Rules 3120 and 3130 should function as challenge processes, not annual paperwork exercises. The Order underscores why supervisory-control testing and CEO certification should surface unresolved surveillance weaknesses, recurring exceptions and prior regulatory findings. Those processes should also produce documented corrective action where necessary.
• Thresholds should trigger documented escalation, not just informal review. When turnover, cost-to-equity, margin use, short holding periods or recurring losses reach concerning levels, firms should identify who reviews the account, what information is considered, when the matter is escalated and how the conclusion is documented.

Background and Sanctions: FINRA Expels Reid & Rudiger and Bars Cofounders

FINRA’s sanctions against Reid & Rudiger and its principals underscore how excessive-trading findings can lead to both firm-level consequences and individual supervisory accountability.

Firm Background and FINRA Settlement Timeline

Reid & Rudiger was a small retail broker-dealer with two branch offices and nine registered representatives. Rudiger served as CEO; Reid was a cofounder and registered representative; Mezzatesta served as CCO; and Harrison was the firm’s majority owner and a designated supervisory principal. FINRA filed the disciplinary proceeding on March 2, 2026. The respondents submitted an Offer of Settlement on June 5, and FINRA accepted it on June 17. In settling, the respondents consented to FINRA’s findings without admitting or denying them.

Firm Expulsion, Individual Bars and Supervisor Penalties

The sanctions reflect the seriousness with which FINRA viewed both the sales-practice conduct and the supervisory failures. FINRA expelled Reid & Rudiger from membership and barred Rudiger and Reid in all capacities. Harrison and Mezzatesta each received a three-month suspension in all principal capacities, a $5,000 fine and an undertaking to complete 20 hours of supervision-related continuing education. The underlying period ran from February 1, 2018 through October 31, 2023, and involved 20 customer accounts, nearly $2.2 million in trading costs and more than $2.7 million in customer losses. Because of the expulsion and bars, FINRA did not impose monetary sanctions or restitution against the firm, Rudiger or Reid.

What FINRA Found

A High-Volume, High-Cost Market-Timing Strategy

FINRA found that Rudiger and Reid repeatedly recommended large equity positions, often on margin, and then recommended selling those positions after relatively short holding periods to finance purchases of different stocks. The firm generally charged commissions of 2% to 4% on purchases and sales, along with a $99 per-trade service charge. Over time, those costs compounded. The significance of the Order lies less in any one trade than in the repeated pattern and the break-even burden that pattern imposed on the affected accounts.

That distinction matters. Many of the customers had aggressive-growth or speculative objectives and, in some cases, high or maximum risk tolerance. FINRA nevertheless concluded that the recommended strategy was unsuitable or not in the customers’ best interests because the cumulative costs were so substantial. A customer’s willingness to assume market risk does not answer whether the economics of a recommended trading strategy are reasonable.

Excessive Trading and Churning Are Related but Distinct

The Order draws a careful line between excessive trading and churning. For retail customers after June 30, 2020, Reg BI’s Care Obligation requires an associated person to have a reasonable basis to believe that a recommended series of transactions, viewed together, is not excessive and is in the customer’s best interest. That inquiry is grounded in the customer’s investment profile and the risks, rewards and costs of the series. Control over the account is not an element.

Churning is different because it is a fraud claim. FINRA described the elements as: (1) actual or de facto control over the customer’s account; (2) trading that is excessive in light of the customer’s investment profile; and (3) scienter. FINRA found those additional elements in certain accounts, including de facto control and conduct undertaken with intent to defraud or, at a minimum, reckless disregard of the customers’ interests while seeking to maximize compensation.

The Regulatory Framework: How FINRA Applied Reg BI, Suitability and Churning Standards

The Reid & Rudiger Order applies several overlapping regulatory standards, including Reg BI, FINRA suitability rules, federal antifraud provisions and FINRA supervision requirements.

Reg BI and the Care Obligation for Excessive Trading

Reg BI applies when a broker-dealer or associated person makes a recommendation of a securities transaction or investment strategy involving securities to a retail customer. The Best Interest Obligation requires the broker-dealer and associated person to act in the retail customer’s best interest at the time of the recommendation and not place their financial or other interests ahead of the customer’s.

The Care Obligation is central to the case. It requires reasonable diligence, care and skill to understand the potential risks, rewards and costs of a recommendation, to have a reasonable basis to believe the recommendation is in the particular retail customer’s best interest, and, for a series of recommendations, to have a reasonable basis to believe the series is not excessive when viewed together. The Reid & Rudiger Order is a useful example of why firms should treat cost as part of the substantive best-interest analysis rather than as a disclosure item considered only after the recommendation has been made.

The Compliance Obligation separately requires broker-dealers to establish, maintain and enforce written policies and procedures reasonably designed to achieve compliance with Reg BI. FINRA charged the firm with violating that obligation because its procedures and surveillance were not reasonably designed to detect excessive trading and churning.

FINRA Rule 2111: Quantitative Suitability Before Reg BI

Rule 2111 remains in effect, but it generally does not apply to recommendations that are subject to Reg BI. For pre-June 30, 2020 conduct and for recommendations outside Reg BI’s retail-customer scope, Rule 2111 remains important. The historical quantitative suitability component required a broker with actual or de facto control over an account to have a reasonable basis to believe that a series of recommended transactions was not excessive when viewed together in light of the customer’s investment profile. Turnover rate, cost-to-equity ratio and in-and-out trading are relevant considerations.

The case also confirms that Reg BI did not make quantitative surveillance obsolete. It changed the legal framework for retail recommendations by moving the series-of-transactions analysis into the Care Obligation and removing control as a prerequisite. A firm that surveils only for classic churning may therefore miss conduct that presents a Reg BI problem even where it could not prove that the broker controlled the account.

Churning Under Section 10(b), Rule 10b-5 and FINRA Rule 2020

FINRA’s churning findings rested on the federal antifraud provisions and FINRA Rule 2020. Section 10(b) and Rule 10b-5 prohibit manipulative or deceptive conduct in connection with securities transactions, while Rule 2020 prohibits a member from effecting or inducing securities transactions by means of manipulative, deceptive or other fraudulent devices or contrivances. FINRA also charged Rule 2010, its broad commercial-honor standard, in connection with the substantive and supervisory violations.

FINRA Rule 3110: Supervisory Systems, WSPs and Exception Reports

Rule 3110 requires each member to establish and maintain a supervisory system, including written procedures, reasonably designed to achieve compliance with applicable securities laws and FINRA rules. In this case, FINRA found that the firm’s WSPs referred to turnover and cost-to-equity ratios but did not tell supervisors how to obtain or calculate those metrics, what levels should trigger further review, or what steps should follow once a concern was identified. The problem, in other words, was not simply that a procedure was missing; it was that the procedure did not give supervisors a workable method for detecting and resolving the risk.

The firm also relied heavily on manual pre-trade, daily and monthly reviews that, according to FINRA, largely duplicated one another. At the same time, the clearing firm offered exception reports capable of identifying turnover and cost-to-equity metrics, but the firm did not obtain or use them. That combination is a recurring supervisory problem: substantial review activity can create the appearance of control while still failing to test the risk that matters. Firms should ask whether their reviews are complementary, whether the right data are reaching the right supervisors and whether escalation criteria are clear enough to produce action when patterns emerge.

CCO Liability: Delegated Supervision, Not Title Alone

The sanction against Mezzatesta should not be read as a departure from FINRA’s stated approach to CCO liability. Regulatory Notice 22-10 explains that supervisory responsibility generally rests with business management and designated supervisors, and that FINRA will not pursue a Rule 3110 failure-to-supervise case against a CCO based solely on the CCO title. The analysis changes when a firm affirmatively delegates supervisory functions to the CCO.

That is what FINRA found here. Reid & Rudiger’s WSPs assigned Mezzatesta pre-trade suitability review, daily and monthly blotter review, and responsibility for obtaining appropriate exception reports. The practical lesson for firms is to review WSPs, organizational charts, committee charters and job descriptions together. They should tell a consistent story about who owns compliance advice, who owns line supervision and where those functions intentionally overlap.

Rules 3120 and 3130: Testing, CEO Certification and Accountability

FINRA did not charge Rules 3120 or 3130 violations in this settlement, so the case should not be characterized as an enforcement action under those provisions. The facts nevertheless make both rules relevant to a firm’s response. Rule 3120 requires testing and verification of the supervisory system. Rule 3130 requires the CEO to certify annually that the firm has processes to establish, maintain, review, test and modify compliance policies and WSPs, with substantive interaction between the CEO and CCO on significant compliance issues.

The 2018 examination findings should have been a meaningful input into those processes. A firm confronting comparable facts should ask whether prior examination findings, branch findings, customer complaints, arbitration claims and recurring surveillance exceptions are feeding the supervisory-control testing plan; whether remediation is assigned to accountable owners; and whether closure is based on testing rather than the fact that a revised procedure was issued.

Supervisory Red Flags: Cost-to-Equity, Turnover, Margin and Unused Exception Reports

The Order highlights several supervisory red flags that broker-dealers should be able to identify, investigate and document as part of an excessive-trading surveillance program.

• Cost-to-equity ratios above 20%. FINRA states that an annualized cost-to-equity ratio of 20% or more generally indicates excessive trading. In this matter, the highest annualized ratio reached 111.59%. The metric is not a mechanical liability threshold, but it should trigger documented review of trading costs, account equity, holding periods, customer objectives and whether the strategy can reasonably overcome its cost burden.
• Turnover rates above six. FINRA identifies an annualized turnover rate of six or more as generally indicative of excessive trading. The highest annualized turnover rate in the affected accounts was 17.33. Firms should be able to calculate the metric, understand the data behind it, investigate outliers in context and document why additional escalation was or was not required.
• High commissions and recurring transaction charges. The firm generally charged 2% to 4% on purchases and sales, plus a $99 per-trade service charge. When those charges recur frequently and are layered with margin interest, the break-even hurdle can become the central economic fact in the account and should be evaluated as part of the firm’s best-interest and excessive-trading analysis.
• Short holding periods and repeated in-and-out activity. Frequent replacement of large equity positions after days or months can be an important pattern-based indicator, particularly where recommendations are solicited and substantially similar across multiple customer accounts.
• Margin use layered onto a high-turnover strategy. Margin increases the customer’s economic burden and should be included in the firm’s cumulative-cost analysis. When a high-turnover strategy also uses margin, supervisors should consider whether interest charges, liquidation risk and increased losses make the recommended trading pattern inconsistent with the customer’s best interest.
• Supervisory silence after known findings. FINRA had already identified surveillance deficiencies and accounts with high turnover and cost-to-equity metrics in its 2018 examination. When the same risk persists after a regulatory finding, the absence of later alerts or escalations should itself prompt scrutiny of whether the remediation actually worked.
• Available surveillance not used. FINRA focused heavily on the fact that exception reports existed but were not obtained. Firms should periodically inventory what data and surveillance their clearing firms and vendors can provide, assign responsibility for reviewing available reports and document why particular tools are or are not used.
• Delegated supervisory duties not matched to tools and workflows. When WSPs assign supervisory responsibility to a principal, CCO or other compliance personnel, the firm should ensure that person has access to the reports, data, escalation criteria and documentation process needed to perform the assigned review. A delegation that exists on paper but is not supported by a workable workflow can become a red flag in itself.

Practical Compliance Considerations for Broker-Dealers: Excessive Trading, Reg BI and Supervision

Broker-dealers can use the Reid & Rudiger Order as a practical checklist for reviewing excessive-trading surveillance, Reg BI compliance, escalation protocols, remediation governance and delegated supervisory responsibilities.

Surveillance Design and Account Economics

• Build excessive-trading surveillance around cumulative account economics. Firms should aggregate commissions, markups and markdowns, service charges, margin interest and other transaction costs over appropriate review periods and assess them alongside average equity, losses, turnover and holding periods. The goal is not to reduce supervision to a single ratio; it is to make the economic pattern visible early enough for documented supervisory review and intervention.
• Use more than one surveillance time horizon. Pre-trade and daily reviews are important, but many excessive-trading patterns become apparent only over months. Depending on the business, firms should consider rolling 30-, 90-, 180- and 365-day views, with longer lookbacks where the relationship or trading strategy warrants it.

Written Procedures, Thresholds and Escalation

• Write procedures that tell supervisors what to do. WSPs should identify the source of relevant metrics, how they are calculated, what thresholds or combinations of factors require escalation, who performs the review, what information should be considered and how the conclusion is documented. A procedure that names a risk without describing the review process may not be enough.
• Do not confuse risk tolerance with tolerance for unreasonable costs. A speculative objective may justify exposure to greater market risk; it does not resolve whether a recommended series can reasonably overcome its cumulative costs or whether transaction-based compensation is influencing the recommendation.

Conflicts, Compensation and Reg BI Controls

• Review compensation structures and conflicts. Firms should evaluate whether commission rates, markups, transaction charges, sales contests or other incentives create pressure for high-volume recommendations and whether Reg BI conflict controls sufficiently mitigate those incentives.

Vendor Reports and Remediation Governance

• Validate clearing-firm and vendor surveillance rather than assuming it works. Firms should confirm that required reports are actually received, assigned and reviewed; understand the underlying calculations; test data completeness; and document why particular surveillance tools are or are not part of the supervisory framework.
• Treat regulatory remediation as a governed process. Examination findings should generate a written plan with accountable owners, milestones, testing, evidence of completion and senior-management reporting. A revised WSP is not the same thing as a remediated control.

Delegated Supervision, Rules 3120 and 3130

• Separate compliance advice from line supervision unless delegation is intentional. Where the CCO or compliance personnel are assigned direct supervisory tasks, WSPs and job descriptions should be explicit. If supervisory duties remain with business principals, procedures should reflect that allocation clearly.
• Use Rules 3120 and 3130 as opportunities for challenge. Supervisory-control testing and CEO certification should force the firm to confront unresolved surveillance gaps, recurring exceptions and prior examination findings. If those processes merely memorialize that annual reviews occurred, they are not serving their intended governance function.

Frequently Asked Questions

Does a firm need to prove account control to establish excessive trading under Reg BI?

No. For retail-customer recommendations subject to Reg BI, the Care Obligation’s series-of-transactions component applies regardless of whether the broker-dealer or associated person controls the customer’s account. Control remains relevant to a traditional churning claim and to the pre-Reg BI quantitative suitability framework.

Do turnover rate and cost-to-equity ratio automatically establish a violation?

No. FINRA states that annualized cost-to-equity ratios of 20% or more and turnover rates of six or more generally indicate excessive trading, but the analysis remains facts and circumstances based. Those metrics should be considered together with trade frequency, holding periods, whether activity was solicited, customer profile, commissions and charges, margin interest, losses and the economics of the strategy. In Reid & Rudiger, the most extreme accounts reached 111.59% cost-to-equity and 17.33 turnover.

Can a customer with a speculation objective consent to very active trading?

Not in the sense that consent or a speculative objective eliminates the broker’s obligations. FINRA repeatedly noted that affected customers had aggressive or speculative objectives and substantial risk tolerance. The issue was whether the recommended series, including its cumulative cost structure, was suitable or in the customer’s best interest. Risk tolerance is part of the analysis, not a waiver of it.

Why was the CCO sanctioned?

Because the firm’s WSPs delegated direct supervisory responsibilities to her. FINRA found that Mezzatesta had primary responsibility for pre-trade suitability review, sole responsibility for daily and monthly blotter suitability reviews, and responsibility for obtaining appropriate exception reports. The case is therefore consistent with FINRA’s broader position that a CCO does not incur Rule 3110 supervisory liability solely because of the CCO title.

What should firms do with prior FINRA examination findings?

Treat them as formal risk inputs and keep them open until effectiveness has been demonstrated.

1. Assign ownership
2. Identify the root cause
3. Implement the fix
4. Test the changed control
5. Report status to senior management
6. Preserve the evidence supporting closure.

A later enforcement matter will focus on whether the firm changed the supervisory system in practice, not simply whether it revised the written procedure.

Conclusion

The Reid & Rudiger matter is a useful reminder that excessive-trading cases are no longer confined to the vocabulary of traditional suitability and churning. For retail customers, Reg BI gives FINRA a series-of-transactions theory that does not depend on proving account control. Where the evidence also establishes control and scienter, the same trading can support a fraud-based churning charge. That distinction should be reflected in how firms design surveillance, investigate exceptions and train supervisors.

The supervisory side of the case may be even more instructive. FINRA had identified the relevant surveillance weakness years earlier, yet the firm’s review practices did not meaningfully change. The Order therefore speaks as much to remediation discipline as it does to sales-practice supervision. Firms should be able to show not only that a deficiency was assigned and a procedure was revised, but that the resulting control was implemented, tested and capable of detecting the conduct that prompted the finding.

A practical way to use the case is to ask four questions of the current supervisory program:

1. Can the firm identify the cumulative economic burden of trading in a customer account?
2. Who is responsible for reviewing the resulting exceptions?
3. What happens when thresholds or patterns warrant escalation?
4. Can the firm produce evidence that prior findings were remediated effectively?

If any answer depends on institutional memory, an unused clearing-firm report or a WSP provision that does not translate into an actual workflow, the issue deserves attention before the next examination, complaint or enforcement matter.
