J. Keith Stucker: Thurston Advisor Faced Churning Complaint

Indianapolis, Indiana financial advisor J. Keith Stucker (CRD# 1094241) allegedly churned investments, according to a recent, denied investor complaint. Financial Industry Regulatory Authority records show that he is registered as a broker and an investment advisor with Thurston Springer.

Mr. Stucker’s BrokerCheck report discloses multiple investor complaints. The most recent, filed in January 2026, alleged that as a Thurson Springer representative, he recommended unsuitable investments and engaged in churning. The complaint alleged unspecified damages and was denied by the firm.

An earlier investor complaint, filed in 2012, alleged that as a representative of RBC Capital Markets, he acted negligently and implemented a strategy that led to underperformance. The complaint alleged damages of $55,000 and was denied by the firm.

In 2020 FINRA released an investor resource that defined excessive trading as “the situation where a broker makes a large number of trades in a customer’s account not to benefit the customer but to generate commissions for the broker.” In more severe cases, known as churning, a broker makes excessive transactions in the client’s account “with either an intent to defraud or with reckless disregard for the customer’s interests.” Additional information on potential red flags indicating excessive trading can be found via FINRA. To catch signs of such conduct, the regulator advises investors to review their account documents for any discrepancies between the information recorded and the information provided to the broker; to monitor trade confirmations and account statements, and contact their broker regarding any potential unauthorized transactions, high-volume activity, or excessive fees or commissions; and to carefully question their representatives about any potential excessive trading.

According to the Financial Industry Regulatory Authority, J. Keith Stucker holds 43 years of securities industry experience. Based in Indianapolis, Indiana, he has been registered as a broker and an investment advisor with Thurston Springer since 2016 and 2020, respectively. His past registrations include Waddell & Reed, RBC Capital Markets, Wachovia Securities, McDonald Investments, Smith Barney, Lehman Brothers, EF Hutton & Company, and Thomson McKinnon Securities. His credentials include the passage of eight securities industry qualifying exams: the Securities Industry Essentials Examination, or SIE; the General Securities Sales Supervisor – General Module Examination, or Series 10; the General Securities Sales Supervisor – Options Module Examination, or Series 9; 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; the National Commodity Futures Examination, or Series 3; and the Interest Rate Options Examination, or Series 5. He holds 22 state licenses. (Information current as of April 7, 2026.)
