Robert Sperber: $2.5mm Complaint Against Morgan Stanley Advisor

A recent investor complaint against Coral Gables, Florida financial advisor Robert Sperber (CRD# 2297059) alleges that his conduct resulted in damages of more than $2 million. Financial Industry Regulatory Authority records show that he is registered as a broker and an investment advisor with Morgan Stanley.

Mr. Sperber’s BrokerCheck report discloses one investor complaint. Filed in December 2025, it alleges that as a representative of Stifel Nicolaus, he acted negligently, breached his fiduciary duty, aided and abetted fraud and conversion, interfered with a customer’s inheritance, and violated “customs and standards of the securities industry.” The pending complaint alleges damages of $2.5 million.

For reference, negligence refers to an advisor’s failure to fulfill their duty of care to their clients. Broadly speaking, that failure takes the form of an advisor doing something that a reasonably prudent advisor would not do under the same circumstances, or not doing something that a reasonably prudent advisor would do. Potentials examples include the recommendation of unsuitable investments, over-concentration of a portfolio, or a failure to complete adequate due diligence on an investment. As with other forms of broker and advisor misconduct, representatives who engage in negligence may be held liable in the event of losses.

Investors should be aware that the conversion of investor funds is strictly forbidden by FINRA Rule 2150. This rule stipulates that no FINRA-registered person “shall make improper use of a customer’s securities or funds.” Conversion may also be considered a violation of FINRA Rule 2010, which states that brokers like Mr. Sperber are required to “observe high standards of commercial honor and just and equitable principles of trade” in the conduct of their business. Representatives who contravene these rules may be held liable for damages and/or subject to disciplinary action.

According to the Financial Industry Regulatory Authority, Robert Sperber holds 33 years of securities industry experience. Based in Coral Gables, Florida, he has been registered as a broker and an investment advisor with Morgan Stanley since February 2025. His past registrations include Stifel Nicolaus & Company, Barclays Capital, Morgan Stanley,  Citigroup Global Markets, UBS Financial Services, CIBC World Markets, Painewebber, Smith Barney Shearson, and Lehman Brothers. His credentials include the passage of five securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the Uniform Investment Adviser Law Examination, or Series 65; the Uniform Securities Agent State Law Examination, or Series 63; the General Securities Representative Examination, or Series 7; and the Futures Managed Funds Examination, or Series 31. He holds 33 state licenses. (Information current as of March 22, 2026.)
