Broker’s History

He entered the securities industry in 2016 and previously worked with MML Investors Services, LLC.

Current and Past Allegations of Conduct Leading to Investment Loss

According to publicly available records released by the Financial Industry Regulatory Authority (FINRA), in July 2025, Jihoon Park was the subject of FINRA regulatory proceedings, alleging that, “Respondent Park failed to respond to FINRA requests for information.” Pursuant to FINRA Rule 9552(h) and in accordance with FINRA’s Notice of Suspension and Suspension from Association letters dated July 1, 2025 and July 25, 2025, respectively, on October 6, 2025, Park is barred from association with any FINRA member in all capacities. Park failed to request termination of his suspension within three months of the date of the Notice of Suspension; therefore, he is automatically barred from association with any FINRA member in all capacities.

In addition, Jihoon Park is the subject of one other customer dispute:

• November 2024—“The complainant alleges that the registered representative, that beginning in/around September 2021, made unsuitable recommendations to invest money from her life insurance and divorce settlement, into crypto currency, and then stole and converted her life savings from those investments. The complainant alleges the Firm is responsible for the wrongful acts of the registered representative.” The damage amount requested is $2,658,000.00 and the customer dispute is still pending.

We Help Investors Recover Investment Losses

Financial advisors have a legal and regulatory obligation to recommend only suitable investments that are appropriate for their clients’ needs and objectives. Their employing brokerage firm has a legal and regulatory obligation to supervise the Financial Advisors’ sales practices and dealings with clients. To the extent any of these duties are breached, the customer may be entitled to a recovery of his or her investment losses.

Reasonable basis suitability requires that a recommended investment or investment strategy be suitable or appropriate for at least some investors. Reasonable basis suitability requires an advisor to conduct adequate due diligence so that he or she can determine the risks and rewards of the investment or investment strategy.

Customer-specific suitability requires that a member or associated person have a reasonable basis to believe that the recommendation is suitable for a particular customer based on that customer’s investment profile. Among the criteria that a financial advisor must evaluate to satisfy his or her customer-specific suitability obligations include the investor’s age, tax status, time horizon, liquidity needs, and risk tolerance; a client’s other investments, financial situation and needs, investment objectives, and any other information disclosed by the customer should also be considered.

Excessive trading often occurs when a Financial Advisor puts his or her interests ahead of the clients and makes transactions solely for the purpose of generating commissions. Financial Advisors have a regulatory duty to recommend suitable investment strategies. One of the components of the suitability analysis is quantitative suitability.

Quantitative suitability requires a brokerage firm or financial advisor with actual or de facto control over a customer’s account to have a reasonable basis for believing that a series of recommended transactions – even if suitable when viewed in isolation – is not excessive and unsuitable for the customer when taken together in light of the customer’s investment profile. No single test defines excessive activity, but factors such as the turnover rate, the cost-equity ratio, and the use of in-and-out trading in a customer’s account may provide a basis for a finding that a member or associated person has violated the quantitative suitability obligation. Financial advisors have a legal and regulatory obligation to recommend only suitable investments that are appropriate for their clients’ needs and objectives. Their employing brokerage firm has a legal and regulatory obligation to supervise the Financial Advisors’ sales practices and dealings with clients. To the extent any of these duties are breached, the customer may be entitled to a recovery of his or her investment losses.
