National investment loss lawyers KlaymanToskes is investigating broker John Lowry (CRD# 4336146) of Spartan Capital Securities.

According to FINRA BrokerCheck, broker John Lowry, CEO of Spartan Capital Securities, LLC, is involved in a FINRA complaint alleging serious supervisory and compliance failures tied to repeated violations of FINRA Rule 8210. The action also names the firm’s Chief Administrative Officer, Kim Monchik, for allegedly delaying, ignoring, or failing to produce required regulatory information during multiple FINRA inquiries. FINRA’s Department of Enforcement is now pursuing disciplinary action that may result in sanctions, monetary penalties, suspensions, or removal from leadership roles.

FINRA’s Allegations Against John Lowry and Spartan Capital

According to FINRA’s complaint (filed November 2024), Spartan Capital and its leadership repeatedly failed to respond to Rule 8210 requests, which require firms to produce documents and information during regulatory investigations. FINRA alleges that these failures obstructed ongoing examinations into private fund sales involving Lowry and Monchik through outside business activities, net capital calculations required for regulatory reporting, and follow-up investigations prompted by incomplete or delayed responses

FINRA’s findings state that the firm’s responses often arrived only after the initiation of expedited proceedings, demonstrating what regulators described as a persistent pattern of non-responsiveness and inadequate supervisory controls. Lowry’s involvement reflects the seriousness of the alleged misconduct and the regulator’s conclusion that Spartan Capital’s leadership failed to ensure timely compliance with essential regulatory requirements. According to FINRA, these lapses point to deeper systemic supervision issues within the firm under Lowry’s oversight.


Systemic Supervision Failures at Spartan Capital

FINRA’s complaint describes a breakdown in Spartan Capital’s compliance structure under Lowry’s leadership:

  • Understaffed and undertrained compliance team
  • No effective tracking system for Rule 8210 deadlines
  • Delegation without verification, resulting in recurring missed deadlines
  • Ignored red flags, including multiple expedited proceedings

These supervisory lapses reportedly hindered investigations into Spartan’s private fund sales, supervisory practices, and net capital compliance.

If proven, FINRA’s findings could result in suspensions, fines, or leadership bars against Lowry and Monchik.
