Investors should understand that, as with all BrokerCheck disclosures, these events are reported by firms, the broker, and/or regulators, and settlements typically occur without an admission of liability. However, the pattern of multiple disputes involving similar allegations in managed portfolios over several years may be a red flag for potential mismanagement of investment accounts and failure to align recommendations with clients’ risk tolerance and objectives.
In light of these settlements and the serious nature of the allegations, current and former customers of Thomas Anthony Kieffer or St. Louis Financial Planners, Inc. who experienced significant losses in managed stock portfolios should consider whether they may have FINRA arbitration claims for negligence and breach of fiduciary duty or unsuitable investment strategies.

Robert Wayne Pearce Is Committed to Recovering Your Investment Losses
FINRA Rule 2111 (Suitability) requires a broker to have a reasonable basis to believe that any recommended transaction or investment strategy is suitable for the customer based on that individual’s investment profile, including age, financial situation, risk tolerance, time horizon, and liquidity needs. When a customer alleges that a managed stock portfolio was unsuitable, too risky, or inconsistent with stated objectives, arbitrators ask whether the broker performed adequate due diligence on the securities and strategy and whether the portfolio was appropriately diversified and aligned with the client’s risk tolerance. In the disputes involving Thomas Kieffer, the allegations of unsuitable investments and large losses in managed individual stock portfolios suggest that claimants may have argued that the portfolio construction and ongoing management violated Rule 2111’s customer-specific suitability obligations.
Section 6. FINRA Rule 2090 – Know Your Customer
FINRA Rule 2090 (Know Your Customer) requires member firms and their associated persons to use reasonable diligence, at account opening and on an ongoing basis, to know and retain the essential facts concerning every customer and the authority of each person acting on the customer’s behalf. Essential facts include information needed to service the account properly, follow special handling instructions, and comply with applicable laws and rules. In the context of the Kieffer complaints, investors may argue that if their accounts were concentrated in volatile stocks or managed with a risk profile inconsistent with their age, financial situation, or stated objectives, then the broker failed to properly “know the customer” and update his understanding of their needs, thereby contributing to the alleged breach of duty and negligent management of their portfolios.
Section 7. FINRA Rule 2010 – Standards of Commercial Honor and Principles of Trade
FINRA Rule 2010 (Standards of Commercial Honor and Principles of Trade) is a broad ethics rule requiring that, in the conduct of their business, members and associated persons observe high standards of commercial honor and just and equitable principles of trade. Even where a particular transaction does not fit neatly into a technical suitability or know-your-customer violation, patterns of conduct involving repeated breach of duty, negligent portfolio management, or failure to act in a client’s best interests can still be charged under Rule 2010. The multiple managed account disputes disclosed on Kieffer’s record—and the substantial settlements paid to customers—could be cited by investors as evidence that his conduct fell below the high ethical standards required by Rule 2010, especially if arbitrators find that he failed to manage risk, follow client objectives, or respond appropriately to market conditions in those accounts.
