Tigress Financial Partners Broker Olivier Gillier Faces $940K Complaint

Financial advisor Olivier Gillier, formerly of Tigress Financial Partners, is currently facing a pending customer complaint alleging $3,100,000 in investor damages. The investor alleges unsuitable investment recommendations, excessive trading, unauthorized trading, churning and failure to supervise. Gillier was registered with Tigress Financial Partners from 2013 to April 2021 in New York, NY.

In 2023, Gillier was suspended for one year by FINRA, and consented to the sanctions and to the entry of findings that he participated in a private securities transaction without providing prior written notice to his member firm. The findings stated that Gillier made a capital contribution of $300,000 in exchange for Class A membership interests in a limited liability company (LLC) formed for the purpose of purchasing and managing a building in New York.

Gillier also facilitated the investments of three individuals, one of whom was a firm customer, who invested a total of more than $2 million in Class B membership interests in the LLC. The right to manage and control the business of the LLC was vested exclusively in a managing member. Neither Gillier nor the Class B investors had any role in the operation or management of the building. Class A and Class B members expected to share in the potential profits of the LLC according to their membership percentages as defined in the LLC’s operating agreement. These Class A and Class B membership interests in the LLC were investment contracts that were securities. Gillier’s involvement in the LLC was outside the scope of his employment with the firm, and he did not provide prior written notice to the firm before investing in the LLC or facilitating the investments of the Class B investors. Gillier also falsely certified on the firm’s annual compliance attestations that he had not engaged in any private securities transactions that had not been previously disclosed to the firm.

Signs Investors Should Look Out For About Their Brokerage Accounts

As an investor, there are a few signs that you should look out for if you believe you may have a claim against your financial advisor. These signs could potentially indicate misconduct, negligence, or investment fraud. Investors are encouraged to contact our firm immediately if you have experienced any of the following:

  • You have substantial losses in your investment accounts
  • You received a call, email, or other communication from your broker’s supervisor or manager regarding your portfolio
  • Your broker misrepresented investment opportunities, or failed to disclose details about investments
  • You notice unauthorized transactions in your investment accounts
  • Your broker is not returning your calls or emails
  • You filed a complaint with your brokerage firm that has not been resolved
  • You see a mistake on your statement, or receive a fraudulent statement

Some investors have close relationships with their brokers due to the time and trust built over the course of their investment relationship. However, it is crucial to remember that financial decisions should be based on careful analysis and due diligence rather than solely relying on personal relationships.

Engaging the services of an experienced securities attorney to evaluate your specific circumstances is strongly advised.
