David Nathan Cohen Complaints: FINRA Bars Former Cetera Broker

David Nathan Cohen Complaints: FINRA Bars Former Cetera Broker featured by top securities fraud attorneys, The White Law Group.

David Nathan Cohen Complaints & FINRA Bar (Cetera) 2026

FINRA barred former Cetera Investment Services broker David Nathan Cohen from the securities industry in all capacities, effective March 3, 2026, after he allegedly refused to appear for on-the-record testimony in an investigation into whether he converted or misappropriated customer funds. Cohen’s FINRA BrokerCheck record also discloses multiple customer complaints alleging misappropriation of funds. Investors who worked with Cohen and believe they lost money may want to speak with a FINRA arbitration attorney about their options.

Who Is David Nathan Cohen?

David Nathan Cohen (CRD #5083883) entered the securities industry in 2006. He was most recently registered with Cetera Investment Services LLC in Yonkers, New York, from June 2019 until his termination in December 2025. Cetera Investment Services is a broker-dealer affiliate of Cetera Advisors LLC under the Cetera Financial Group umbrella; see our review of Cetera Advisors for more on the firm’s broader regulatory history. Before that, he was registered with Foresters Financial Services, Inc. in New York from 2006 to 2019. According to his FINRA BrokerCheck report, Cohen also disclosed an outside business activity as a 95% owner of Ballparking Ventures LLC, described as a mobile app for locating and renting parking spaces.

Termination for Trading While Suspended

Cetera Investment Services discharged Cohen on December 9, 2025. According to the firm’s disclosure, Cohen was discharged for allegedly transacting business while under suspension and allegedly failing to cooperate with the firm’s internal review of allegations that client funds were purportedly paid directly to him and used to support his outside business.

FINRA Bar Over Refusal to Testify

FINRA’s disciplinary action against Cohen did not resolve the underlying misappropriation allegations. Instead, according to the regulator’s Acceptance, Waiver and Consent (AWC) letter, Cohen was barred because he allegedly refused to appear for on-the-record testimony that FINRA requested as part of its investigation into whether he converted or misappropriated customer funds, in alleged violation of FINRA Rules 8210 and 2010.

Without admitting or denying the findings, Cohen consented to the sanction. FINRA imposed a permanent bar from associating with any FINRA member firm in any capacity, effective March 3, 2026 (Docket/Case No. 2025088109801).

Customer Complaints and Disputes Against David Nathan Cohen

Cohen’s BrokerCheck report discloses four customer disputes, all involving allegations against Cetera Investment Services LLC:

One dispute alleged misappropriation of funds with $25,000 in claimed damages; it settled for $25,000. A second alleged that the proceeds of a liquidated annuity, which the client believed were going toward investment purchases, were instead allegedly paid directly to Cohen; the client claimed $250,550.19 in damages, and the dispute settled for $250,050.19. A third, filed as a FINRA arbitration, alleged misappropriation of funds involving listed equities with $500,000 in claimed damages; it settled for $499,500. A fourth dispute, filed in January 2026, alleges Cohen purportedly received wire transfers directly from a client as part of an alleged fraud, with an amended statement of claim seeking $500,000 in damages; that matter remains pending as of this writing.

Settlements of this kind are not findings of wrongdoing, and the pending dispute involves allegations that have not been proven.

Tax Liens

Cohen’s record also discloses three outstanding federal tax liens filed by the IRS: $232,470.15 (filed October 2023), $61,245.67 (filed December 2019), and $73,650.00 (filed June 2017), for a combined total of roughly $367,000.
