Allen Stevens: Stifel Advisor Received $200K Complaint

A recent, denied investor complaint against Denver, Colorado financial advisor Allen Stevens (CRD# 1804469) alleged that his advice resulted in six-figure damages. Financial Industry Regulatory Authority records show that he is registered as a broker and an investment advisor with Stifel Nicolaus & Company.

Mr. Stevens’ BrokerCheck report discloses multiple investor complaints. The most recent, filed in March 2026, alleged that as a representative of Stifel Nicolaus & Company, he recommended unsuitable stock investments. The complaint alleged damages of $200,000 and was denied by the firm.

An earlier investor complaint, filed in 2017, alleged that as a Stifel Nicolaus representative, he breached his fiduciary duty, acted negligently, recommended unsuitable investments, breached contract, violated state securities law, and negligently misrepresented material facts. The complaint alleged damages of $249,000 and was denied by the firm.

A third investor complaint, filed in 2017, alleged that as a Stifel representative, he committed fraud, recommended unsuitable investments, and engaged in negligence. The complaint evolved into an arbitration proceeding before a FINRA panel, which issued an award to the customer of $13,500.

For reference, FINRA’s suitability standard holds that brokers like Mr. Stevens must “have a reasonable basis to believe” that the recommendations they make to their clients are appropriate for those clients’ background and needs. As laid out in FINRA Rule 2111, the standard requires brokers to ascertain an investment’s suitability through “reasonable diligence” into the client’s investment profile, which includes their age, net worth, risk tolerance, income, and more. They must arrive a reasonable basis to believe the recommendation is suitable for at least some investors, as well as a reasonable basis to believe it is suitable for the specific customer they’re dealing with. When they are considering a series of transactions in an account over which they have actual or de facto control, they must arrive at a reasonable basis to believe that the series of transactions, “even if suitable when viewed in isolation, is not excessive and unsuitable for the customer.”

According to the Financial Industry Regulatory Authority, Allen Stevens holds 38 years of securities industry experience. Based in Denver, Colorado, he has been registered as a broker and an investment advisor with Stifel Nicolaus & Company since 1994 and 2004, respectively. His past registrations include Everen Securities, Neidiger Tucker Bruner, HT Fletcher Securities, Dean Johnson & Burke, Anderson Bryant & Company, Tri-Bradley Investments, Kober Financial Corporation, and Power Securities Corporation.
