Former Morgan Stanley Broker, Constantinos Maniatis, Suspended by FINRA – Dallas, Texas

The Financial Industry Regulatory Authority (“FINRA”) has suspended financial advisor Constantinos Maniatis from the securities industry for 30 days.  Mr. Maniatis consented to the suspension after FINRA alleged that he engaged in discretionary trading without written authorization in seven customer accounts between May 4, 2018, and February 27, 2019.  FINRA also fined Mr. Maniatis $5,000.

The alleged conduct occurred while Morgan Stanley employed Mr. Maniatis in Dallas, Texas.   Morgan Stanley discharged Mr. Maniatis in May 2019, alleging misconduct related to a non-discretionary account and diverting of revenue from “assigned rep code.”

FINRA Letter of Acceptance, Waiver, and Consent No. 2019062788601

FINRA and Mr. Maniatis entered into a Letter of Acceptance, Waiver, and Consent No. 2019062788601on April 26, 2021, after FINRA alleged that between May 4, 2018, and February 27, 2019, while associated with Morgan Stanley, Mr. Maniatis exercised discretion in seven customer accounts despite the fact that Morgan Stanley no longer permitted such discretionary trading.  Several of the transactions at issue involved municipal securities.   Specifically, FINRA alleged:

  • During the relevant time period, between May 4, 2018, and February 27, 2019, Maniatis exercised discretion in seven customer accounts on 105 occasions.
  • Thirteen of the transactions involved municipal securities.
  • Although Morgan Stanley and the customers had previously authorized the exercise of discretion in the customer accounts at issue, at the time of the transactions at issue, Morgan Stanley did not permit the exercise of discretion in the accounts and no longer accepted the accounts as discretionary accounts.
  • Accordingly, Mr. Maniatis violated NASD Rule 2510(b), FINRA Rule 2010, and MSRB Rule G-17

Unauthorized trading often occurs in non-discretionary accounts, where a customer retains discretion.  In non-discretionary accounts, brokers must obtain a customer’s permission every time before placing a trade.

Unauthorized trading is an unethical and illegal practice.  It is also a violation of securities rules and regulations and can cause enormous harm to customers.

Morgan Stanley – A Duty to Supervise

Financial institutions like Morgan Stanley must properly supervise financial advisors and customer accounts.  Brokerage firms must establish and maintain a reasonably designed system to oversee account activity, such as unauthorized trading, to ensure compliance with securities laws and industry regulations.   When a brokerage firm fails to supervise its financial advisors or the investment account activity sufficiently, it may be liable for investment losses sustained by customers.
