FINRA Permanently Bars Joseph E. O’Shea Jr. of Spartan Capital Securities for Refusing to Testify in Excessive Trading Investigation

If you are a current or former client of Joseph E. O’Shea Jr. and are concerned about the trading activity in your accounts at Spartan Capital Securities, you should know that FINRA has permanently barred O’Shea following findings that he refused to appear for on-the-record testimony requested by FINRA in connection with an investigation into his potential excessive trading in his customers’ accounts.

Joseph E. O’Shea Jr. (CRD# 2805483), formerly a General Securities Representative with Spartan Capital Securities, LLC (CRD# 146251) in New York, NY, is no longer registered with any FINRA member firm.

Findings

Without admitting or denying the findings, O’Shea consented to the sanction and to the entry of findings that he refused to appear for on-the-record testimony requested by FINRA in connection with an investigation into his potential excessive trading in his customers’ accounts at his member firm.

According to the AWC, on December 1, 2025, in connection with an investigation into O’Shea’s potential excessive trading in his Spartan customers’ accounts, FINRA sent O’Shea a request for on-the-record testimony pursuant to FINRA Rule 8210. According to the AWC, as stated during his phone call with FINRA staff on December 8, 2025, and by this agreement, O’Shea acknowledges that he received FINRA’s request and will not appear for on-the-record testimony at any time. According to the AWC, by refusing to appear for on-the-record testimony as requested pursuant to FINRA Rule 8210, O’Shea violated FINRA Rules 8210 and 2010.

According to BrokerCheck, O’Shea was also the subject of a written customer complaint received on February 5, 2024, covering the period July 2023 through February 2024, with alleged allegations of excessive trading and commissions, and alleged damages of $50,000. According to BrokerCheck, the complaint involved equity-OTC securities, listed equities, and options, and was closed with no action on March 21, 2024.

Background

FINRA Rule 8210 authorizes FINRA to require any person associated with a member firm to provide information orally and to testify under oath or affirmation in connection with any FINRA investigation or examination. Rule 8210(c) states that no such person shall fail to provide information or testimony as required. The rule exists to protect the integrity of FINRA’s regulatory oversight: without it, brokers could refuse cooperation with investigations without consequence, and FINRA’s ability to protect investors would be fundamentally compromised.

FINRA treats a refusal to appear for on-the-record testimony as a violation of both Rule 8210 and Rule 2010, which requires persons associated with a FINRA member to observe high standards of commercial honor and just and equitable principles of trade. According to the AWC, the investigation that prompted FINRA’s testimony request concerned O’Shea’s potential excessive trading in his Spartan customers’ accounts.

Excessive trading occurs when a broker recommends or executes trades in a customer’s account at a frequency that serves the broker’s financial interests rather than the customer’s investment goals. Commissions are generated on each transaction, creating an incentive for brokers to trade actively even when doing so harms the customer.

For recommendations made on or after June 30, 2020, Regulation Best Interest requires brokers to act in the customer’s best interest, including by avoiding excessive trading. For earlier conduct, FINRA Rule 2111 required brokers to have a reasonable basis for every recommendation, including that the overall frequency of trading was consistent with the customer’s investment profile. FINRA Rule 2010 requires that brokers observe high standards of commercial honor and just and equitable principles of trade; excessive trading that generates commissions for the broker while harming the customer’s account violates this rule.

FINRA Rule 12206 governs eligibility for arbitration claims. Investors considering a claim should consult with a securities arbitration attorney to evaluate whether their situation falls within the applicable timeframe.

Warning Signs

If you received investment recommendations from a broker and are concerned about whether those recommendations were made in your best interest, consider the following:

• Did your account experience frequent buying and selling of securities, particularly over short holding periods?
• Did you generate significant commission costs relative to the overall performance of your account?
• Were you invested in options or equity securities at a frequency or concentration that was inconsistent with your stated risk tolerance or investment objectives?
• Did you experience account losses that your broker attributed to general market conditions while commissions remained consistently high?

If any of these patterns apply to your account, a free consultation with a securities law attorney can help you understand whether you have a potential claim for damages.

Sanctions

According to the AWC, O’Shea was sanctioned with a bar from associating with any FINRA member in all capacities. According to BrokerCheck, the bar is permanent, covering all capacities, with a start date of December 31, 2025.
