Sung Moo Cho with Citigroup and Ameriprise is Barred from the Securities Industry

Israels & Neuman is looking into allegations against financial advisor, Sung Cho, who previously worked with Citigroup Global Markets and Ameriprise Financial Services in New York City. This advisor was recently barred from the securities industry for failing to respond to an investigation by FINRA.

Allegations Against Sung Cho

FINRA started its own investigation into Sung Cho after being fired by Citigroup Global Markets in April 2026. FINRA alleged that it was investigating allegations as to “whether Cho misappropriated customer funds, forged customer signatures, and falsified firm documents while associated with Ameriprise and Citigroup”. Cho did not cooperate with FINRA’s investigation, and as such, he was barred under FINRA Rule 8210.

Citigroup disclosed on BrokerCheck that Cho removed “customer personally identifiable information from firm systems to create non-firm generated statement that was provided to a client as well as refusal to cooperate with an internal investigation”. In essence, it appears that this advisor was creating statements that were not approved by Citigroup, a sign that he was selling investments that were not approved by Citigroup.

Background on Sung Moo Cho

Sung Cho was licensed with Citigroup Global Markets from October 2025 to April 2026. He was also previously licensed with Ameriprise Financial Services from January 2021 to October 2025 and worked in a New York, NY office. He was also the subject of a customer complaint in 2009.

Are Ameriprise and Citigroup Potentially Liable for Customer Losses?

FINRA standards provide that brokerage firms like Ameriprise and Citigroup must reasonably supervise the activities of their financial advisors. Firms that fail to do so could be responsible for investor losses.
