Ariel Rivero Investigation

April 2023 -Miami, Florida, USA /Buenos Aires, Argentina

We are investigating former Jefferies LLC financial advisor Ariel A. Rivero on behalf of a client residing in Buenos Aires who alleges that they were enticed by Ariel Rivero to invest in a private company owned by Ariel Rivero’s now deceased brother Diego F. Rivero of Buenos Aires, Argentina.

LMS Investments LLC-Argentina ATM Business

Our client believed they were investing in an ATM business to be operated in Buenos Aires, called LMS Investment LLC. Other companies with possible ties include:

The Financial Industry Regulatory Authority (FINRA) is the agency that licenses and regulates stockbrokers and brokerage firms. FINRA requires brokers and brokerage firms to report customer complaints and disputes as well as regulatory sanctions. In addition brokers are required to disclose certain financial matters such as personal bankruptcies, judgments and liens.

Ariel Rivero

According to publicly available records Ariel Rivero,  was employed by Jefferies LLC from 5/2016-1/2022. During this same time frame he was also registered with Leucadia Asset Management, an investment advisory firm headquartered in New York City. Per FINRA records, in 12/2021 a customer of Jefferies LLC was paid $260,000 to resolve allegations that Ariel Rivero breached his fiduciary duties by placing Claimant into unsuitable and risky investments and made unauthorized use of client funds. Claimant also alleged that Jefferies failed to maintain an adequate system of supervision and failed to supervise Rivero.

In 12/2021 Ariel Rivero left Jefferies LLC and joined Insigneo Securities LLC, located in Miami, FL.
