Mark Korona: UBS Financial Services Advisor Faces $15mm Complaint

A recent investor complaint against Lexington, Kentucky financial advisor Mark Korona (CRD# 4747579) alleges that his advice resulted in eight-figure damages. Financial Industry Regulatory Authority records show that he is registered as a broker and an investment advisor with UBS Financial Services.

Mr. Korona’s BrokerCheck report discloses one investor complaint. Filed in August 2026, it alleges that as a representative of UBS Financial Services, he recommended an “overly risky long-term US Treasuries and options overlay strategy.” The pending complaint alleges damages of $15,000,000.

FINRA rules stipulate that brokers like Mr. Korona can only recommend investments and strategies that are suitable for a given customer. Under FINRA Rule 2111, a broker must “have a reasonable basis to believe that a recommended transaction or investment strategy” is appropriate for the customer’s objectives, a basis reached through reasonable diligence into the customer’s investment profile. FINRA Rule 2010, meanwhile, requires representatives to “observe high standards of commercial honor and just and equitable principles of trade.” Brokers who recommend unsuitable investments may be held liable in the event of losses.

According to the Financial Industry Regulatory Authority, Mark Korona holds 22 years of securities industry experience. Based in Lexington, Kentucky, he has been registered as a broker and an investment advisor with UBS Financial Services since 2010. His past registrations include JP Morgan Securities and Merrill Lynch. His credentials include the passage of four securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the General Securities Representative Examination, or Series 7; the National Commodity Futures Examination, or Series 3; and the Uniform Combined State Law Examination, or Series 66. He holds 28 state licenses. (Information current as of September 7, 2026.)
