Why Our Investigation Matters to Investors

As former Wall Street defense attorneys, we bring “insider knowledge” to identify patterns of misconduct and regulatory concerns that ordinary investors may never spot. Our primary goal is to help you maximize your recovery if you have experienced misrepresentations, unsuitability, or losses related to the actions of Mary Duncan at J.P. Morgan Securities LLC.

Mary Duncan, J.P. Morgan Securities LLC: Summary of Public Records

We conducted an in-depth review of BrokerCheck and associated public databases as of June 15, 2026. The key findings regarding Mary Duncan, currently registered in Florida, are outlined below.

Disclosure Description
Customer Dispute
  • Date of Complaint: April 3, 2026
  • Product Involved: Managed Account
  • Allegations: Misrepresentation of a managed account
  • Activity Date: February 13, 2026
  • Damages Sought: $8,450
  • Settlement: Resolved for $2,059.15 on May 29, 2026. Mary Duncan’s reported individual contribution: $0.00

Based on BrokerCheck, Mary Duncan’s regulatory history does not currently reflect any other customer-initiated arbitration claims, regulatory actions, civil litigation, or criminal charges. However, the presence of a settled misrepresentation dispute is a significant red flag that merits investor attention and further analysis.

Understanding the Regulatory Framework: Why Misrepresentation Matters

Financial advisors like Mary Duncan are bound by strict industry rules designed to protect your interests. Two primary regulations are in focus in this investigation:

  • FINRA Rule 2020: Prohibits the use of manipulative, deceptive, or other fraudulent devices in securities transactions. Even a single claim of misrepresentation could indicate violations of fundamental investor protections.
  • FINRA Rule 2111 (Suitability): Requires that all brokerage recommendations align with the investor’s specific objectives, risk tolerance, financial profile, and investment horizon.

Additionally, the U.S. Securities and Exchange Commission’s Regulation Best Interest (Reg BI) mandates that brokers act in your best interests—placing your goals ahead of any product incentives, firm quotas, or conflicts of interest. Brokers must disclose all material facts and carefully consider every recommendation’s costs, risks, and alternatives before acting on your behalf.

Red Flags: The Customer Dispute Against Mary Duncan

The dispute against Mary Duncan reported the following circumstances:

  • A customer alleged that Ms. Duncan directly misrepresented details of a managed account on or around February 13, 2026.
  • The customer sought $8,450 in damages—a claim significant enough to require a full internal and regulatory review.
  • The complaint settled for $2,059.15, signaling that the complaint was not dismissed as baseless.
  • Mary Duncan’s BrokerCheck report lists her individual financial contribution to the settlement as $0.00, indicating the settlement was likely paid by the firm or a related entity.

While one complaint does not necessarily confirm a pattern of misconduct, these facts should prompt vigilance among investors who worked with Ms. Duncan or other representatives at J.P. Morgan Securities LLC.
