FINRA complaint alleges Sutter Securities and former CEO Keith Moore failed to stop $2.5 million in excessive trading in an 89-year-old client's accounts. June 19, 2026 If you or an aging parent held a brokerage account that was traded heavily, generated steady commissions, and lost money while the broker rarely called to explain why, a complaint FINRA filed against an Irvine, California broker-dealer may sound familiar. On January 20, 2026, FINRA filed a disciplinary complaint against Sutter Securities Incorporated (CRD #30770) and its former chief executive officer, Keith Charles Moore (CRD #5191450), alleging that the firm allowed a representative to run up approximately $2.5 million in trading costs and more than $1.8 million in realized losses in the accounts of a retired, 89-year-old customer. This is a formal complaint, not a settled or decided case. According to FINRA, issuance of a disciplinary complaint represents the initiation of a formal proceeding in which findings as to the allegations have not been made. The matter is docketed as FINRA Case #2021071987902. What the FINRA complaint alleges. According to the FINRA complaint, Sutter Securities, acting through one of its registered representatives, willfully violated Regulation Best Interest when it failed to act in the best interests of a customer at the time a series of securities transactions were made. The complaint alleges that the representative recommended and effected 2,217 trades in accounts belonging to a retired, 89-year-old customer that was excessive and not in the customer's best interests. In many instances, according to the complaint, the representative did not consult the customer before placing trades in the customer's accounts. According to the complaint, the customer's accounts incurred approximately $2.5 million in trading costs and more than $1.8 million in realized losses. The complaint does not name the representative; it names the firm and Moore, who FINRA alleges served as the firm's CEO and the representative's direct supervisor. It is important to note that, as of the time of this report, the complaint is still pending. No findings of wrongdoing have been made. The allegations described here are unproven, and the firm and Moore are entitled to contest them. The supervision and red-flag allegations against Keith Moore. According to the FINRA complaint, the firm and Moore failed to identify and reasonably investigate and follow up on red flags indicating that the representative was engaged in potentially excessive and unsuitable trading. The complaint describes two red flags in particular. First, according to the complaint, the representative told Moore that he was executing a replication strategy that was specifically mirroring the trades of a third-party asset manager in the customer's account, but the trading pattern he recommended and effected did not resemble the asset manager's approach. Second, the complaint alleges it was a further red flag that the representative was systematically marking the transactions as "unsolicited" while he was purportedly implementing an investment strategy in the customer accounts while still charging the customer a substantial commission. According to the complaint, Moore knew or should have known of the trading activity and the substantial commissions that the trading activity generated each month through his claimed review of the daily trade blotter and the monthly commission statements. The complaint further alleges that the firm failed to have a supervisory system, including written supervisory procedures, reasonably designed to achieve compliance with the suitability requirements of FINRA Rule 2111 and, as of June 30, 2020, Reg BI's Care Obligation, regarding excessive trading. According to the complaint, the firm's supervisory system did not use metrics, exception reports, or surveillance tools to identify potential excessive trading, failed to implement any system ensuring required suitability reviews were conducted, and provided no procedures or system for responding to potential excessive trading once identified. The complaint also alleges that the firm failed to establish, maintain, and enforce a supervisory system, including written supervisory procedures, reasonably designed to supervise the electronic communications of its registered representatives, and that the firm's system to review email was unreasonable because it relied on fragmented, undocumented, ad hoc reviews by multiple individuals without standardization procedures, supervision tools, or designated oversight responsibility. BrokerCheck records show that Keith C. Moore is not currently registered and that he was registered with Sutter Securities Incorporated from April 2019 to February 2024. How excessive trading harms investors. Excessive trading, sometimes called churning when it is done to generate commissions, is one of the oldest forms of brokerage misconduct. The harm does not come from any single trade. It comes from the volume. Each purchase and sale carries a commission or other cost, and when a broker turns an account over again and again, those costs compound into a steady drain on the account, regardless of whether the market moves up or down. Regulators and arbitrators commonly look at two measures to evaluate whether trading was excessive: the turnover rate, which measures how many times the value of a portfolio was reinvested over a year, and the cost-to-equity ratio, which measures how much the account would have to earn just to cover the trading costs and break even. When those numbers climb, the account is effectively working for the broker rather than the customer. An 89-year-old retired customer typically has a conservative profile and a need to preserve capital, which makes high-volume, high-cost trading especially difficult to justify. The complaint also highlights a recurring feature of these cases: how the trades were labeled. Marking transactions as "unsolicited," meaning the customer initiated them, can keep recommended trades from triggering suitability review. When the label does not match what actually happened, the paperwork can obscure the very activity that supervision is supposed to catch. The rules at the center of the complaint. The complaint rests on a small set of core obligations. SEC Regulation Best Interest (Reg BI, 17 C.F.R. § 240.15l-1) requires a broker-dealer and its representatives to act in the retail customer's best interest when making a recommendation, and its Care Obligation can reach a series of recommended transactions that, taken together, may be excessive. According to the complaint, for conduct before Reg BI took effect on June 30, 2020, FINRA Rule 2111 (suitability) imposed a parallel duty, and the complaint references both standards. The complaint also puts supervision at issue. FINRA's supervision rule, Rule 3110, requires a firm to establish and maintain a supervisory system, including written supervisory procedures, reasonably designed to achieve compliance with the securities laws and FINRA rules, and to supervise its representatives' communications. According to the complaint, the firm lacked a supervisory system reasonably designed to detect excessive trading and lacked a reasonable system for reviewing email, which are the kinds of supervisory duties that rule governs. What this means for investors, including older clients. A FINRA complaint is the regulator's action. It does not by itself put money back in a harmed customer's pocket. Investors who lost money in circumstances like those described in the complaint generally pursue recovery separately, most often through FINRA arbitration, where a customer can seek to recover investment losses, the commissions and costs charged to the account, and in appropriate cases other damages. Eligibility to bring a claim is governed in part by FINRA Rule 12206, and because timing rules can be strict, investors who believe they were harmed should not wait to evaluate their options. Older investors may have additional protections. Under California law, a customer who is 65 or older may have claims for financial elder abuse under Welfare and Institutions Code sections 15610.30 and 15657.5, which can allow for enhanced remedies, including attorney's fees and, in appropriate cases, additional damages. Whether any of these theories applies depends on the specific facts, including where the customer lived and the nature of the account and the conduct.
