FINRA Suspends Zachary Ellis Taylor for Willful Violations
Zachary Ellis Taylor (CRD #6074776), a former broker with Oppenheimer & Co. Inc. and Merrill Lynch, was recently suspended by the Financial Industry Regulatory Authority (FINRA). The suspension, issued in August 2025, bars Taylor from associating with any FINRA member firm in any capacity for nine months.
According to the FINRA settlement order (No. 2022075083801), regulators found that Taylor willfully violated federal securities laws and Regulation Best Interest (Reg BI). The findings indicate that between August 2020 and June 2023, Taylor recommended speculative options strategies to at least three senior customers. These clients, who had balanced allocation objectives and moderate risk tolerances, were advised to sell large volumes of high-risk put options in high-volatility technology stocks.
When these options were assigned, the customers suffered significant losses. FINRA determined that these recommendations were unsuitable given the customers’ investment profiles and were not in their best interest. While no monetary fine was imposed due to Taylor’s inability to pay, the finding of a “willful” violation is a significant regulatory mark.

Termination for Unauthorized Trading Allegations
The employment history of Zachary Ellis Taylor further underscores the risks alleged by investors. In May 2023, Oppenheimer & Co. Inc. discharged Taylor from his position.
The firm reported that the termination was due to Taylor’s inability to provide sufficient documentary evidence to prove he had authorization for trades executed in a client’s account. In the securities industry, trading without written discretionary authority or specific verbal confirmation for each transaction is known as unauthorized trading. This practice deprives investors of control over their own portfolios and is a common violation cited in investment loss claims.

Oppenheimer fired Zachary Taylor because he couldn’t prove he had authorization for his trades.

When a firm lets that standard slip long enough for senior investors to lose hundreds of thousands of dollars, the firm shares that accountability.
