FINRA Regulatory Investigations

​

At AMW Law PLLC, we provide legal counsel to firms and individuals facing FINRA regulatory investigations. With 20 years of securities law experience, our founding attorney—formerly Senior Enforcement Counsel at FINRA—has handled numerous enforcement and regulatory matters from both the regulator’s and the defense’s perspectives. This unique insight allows us to develop effective strategies to navigate FINRA inquiries and enforcement actions.

 

What Are FINRA Regulatory Investigations?

 

FINRA (Financial Industry Regulatory Authority) initiates regulatory investigations to ensure compliance with securities laws and industry standards. These investigations can arise from customer complaints, regulatory audits, market surveillance, whistleblower reports, or referrals from other regulators such as the SEC. A FINRA investigation may lead to disciplinary actions, sanctions, or referrals to other authorities.

 

What Triggers a FINRA Investigation?

 

FINRA investigations can be initiated for various reasons, often based on concerns about potential misconduct, compliance failures, or market irregularities. Understanding the common triggers for a FINRA inquiry is essential for firms and registered representatives to mitigate risks and proactively address regulatory concerns. Common triggers for a FINRA inquiry include:

 

• Customer Complaints – Customer complaints often serve as the catalyst for FINRA investigations, whether they originate from retail investors or institutional clients. Complaints may allege a range of misconduct, including misrepresentation of investments, unsuitable recommendations, unauthorized trading, excessive fees, or failure to disclose material information. Even a single complaint can trigger a FINRA inquiry, and multiple complaints or patterns of allegations may lead to an in-depth investigation into a firm’s supervisory practices and compliance framework. Retaining an experienced FINRA defense attorney is crucial to successful defense.

• Market Manipulation & Trading Irregularities – Suspicious trading patterns, including high-frequency trading anomalies, prearranged trades, wash sales, and layering strategies, which can indicate market manipulation.

• Supervisory & Compliance Deficiencies – Failures in internal controls, AML compliance, or recordkeeping violations can expose firms to significant regulatory scrutiny. Firms are required to maintain rigorous supervisory systems to ensure compliance with FINRA rules, SEC regulations, and other industry standards. Deficiencies may include inadequate monitoring of registered representatives, failure to detect and prevent financial crimes such as money laundering, weak cybersecurity protections, and gaps in trade reporting and surveillance. Firms that fail to establish and enforce strong supervisory procedures risk facing disciplinary actions, fines, and reputational harm.

• Outside Business Activities (OBAs) & Private Securities Transactions – FINRA closely scrutinizes outside business activities (OBAs) and private securities transactions (PSTs) to ensure they do not create conflicts of interest, expose investors to undisclosed risks, or violate regulatory requirements. Registered representatives must properly disclose all outside business activities to their firms, which in turn have an obligation to assess whether the activity requires heightened supervision or firm approval. Failure to disclose an OBA or participation in an unauthorized private securities transaction can lead to serious disciplinary actions, including fines, suspensions, or even industry bars. Proactive compliance is essential to avoid these issues and legal guidance from a securities defense attorney experienced is critical once regulatory investigations arise.

• FINRA Arbitrations – When disputes between customers and broker-dealers escalate into arbitration, FINRA may launch parallel investigations to assess whether regulatory violations contributed to the dispute. Allegations of fraud, unsuitability, or unauthorized trading raised in arbitration cases often draw regulatory scrutiny, increasing the risk of enforcement actions.

• Amendments to Forms U4 and U5 – FINRA closely monitors amendments to the Form U4 (Uniform Application for Securities Industry Registration) and Form U5 (Uniform Termination Notice for Securities Industry Registration). Disclosures related to customer complaints, regulatory actions, terminations, or financial events such as bankruptcies or liens can trigger an investigation into a representative’s conduct and compliance history. More detailed discussion about Forms U4 and U5 can be found on our blog here: FINRA Registration Forms U-4 and U-5: Purpose, Disclosure Obligations and Regulatory Risks.

 

What Are the key Challenges of a FINRA Investigation?

 

When FINRA initiates an investigation, firms and registered individuals may receive:

​

• Document Requests (Rule 8210 Requests) – FINRA has broad authority to compel firms and associated persons to produce documents and records. These requests may cover a wide range of materials, including emails, trade confirmations, account statements, compliance manuals, and internal communications. Responding to Rule 8210 requests requires careful attention, as incomplete or delayed responses can result in disciplinary action. Firms and individuals must ensure that they provide accurate and complete information while also protecting their legal rights during the process. We discuss Rule 8210 in great detail on our blog  Understanding On-the-Record Interviews and Requests for Documents Under FINRA Rule 8210.

• On-the-Record Testimony (OTR) – Witnesses and respondents may be required to testify under oath as part of a FINRA investigation. These testimonies are recorded and can be used as evidence in enforcement actions. The questioning can be extensive and probing, often covering trading activity, supervisory roles, compliance procedures, and potential regulatory violations. Failing to provide truthful and complete responses can lead to severe penalties, including fines, suspensions, or industry bars. Given the high stakes, skilled legal representation is crucial to ensure proper preparation, strategic responses, and protection of the client’s rights throughout the process.

• Wells Notices & Enforcement Actions – If FINRA determines that violations occurred, it may issue a Wells Notice, giving the respondent an opportunity to respond before formal charges are filed.
