According to FINRA, Jeffrey Steven Tabak (CRD #856416), a registered representative based in New York, New York, was fined a total of $10,000 (of which $722 is payable to FINRA), suspended from association with any FINRA member in any principal capacity for six months, and required to complete 10 hours of continuing education concerning supervisory responsibilities. Tabak was found in violation of FINRA rules for failing to establish, maintain, and enforce supervisory systems and procedures reasonably designed to detect market manipulation.
As his member firm's designated principal, Tabak bore primary responsibility for ensuring that the firm's supervisory infrastructure was adequate to identify and prevent potentially manipulative trading activity. FINRA's findings revealed multiple deficiencies in this area. The firm's Written Supervisory Procedures (WSPs) did not reasonably describe how to detect and prevent potentially manipulative trading. Additionally, the firm's exception reports, which are automated alerts designed to flag suspicious trading patterns, did not contain the information needed to properly assess whether customers were engaged in potentially manipulative trading activity.
Beyond these systemic failures, Tabak also failed to reasonably investigate wash trades in an account belonging to the firm's foreign affiliate. Wash trades are transactions where the same party is essentially both the buyer and seller, creating the illusion of market activity without any genuine change in ownership. These trades can be used to manipulate market prices or trading volumes and are prohibited under federal securities laws.
Without admitting or denying the findings, Tabak consented to the sanctions through an AWC agreement issued on August 6, 2024. The six-month suspension in any principal capacity was in effect from September 3, 2024, through March 2, 2025. Notably, Tabak's suspension was limited to principal capacities, reflecting the supervisory nature of the violations. This matter is documented under FINRA Case #2020067122301.
This case highlights the critical importance of robust supervisory systems at brokerage firms. Effective supervision is the first line of defense against market manipulation, which harms all market participants by distorting prices and undermining confidence in the fairness of the markets. When a firm's designated principal fails to implement adequate supervisory procedures, it creates an environment where manipulative trading can go undetected and unchecked.
For investors, this case serves as a reminder that the quality of a firm's compliance and supervision infrastructure matters. Investors should consider the regulatory history of both their individual broker and the firm with which they are associated when making decisions about where to place their investments and trust.
