Kostas Tsamos Suspended for Excessive Trading Violating Regulation Best Interest
According to FINRA, Kostas Tsamos (also known as Gus Tsamos) was suspended from association with any FINRA member in all capacities for 17 months on October 8, 2024. In light of Tsamos' financial status, no monetary sanction was imposed.
Tsamos willfully violated the Best Interest Obligation under Regulation Best Interest by recommending a series of trades in customers' accounts, four of whom were senior customers, which was excessive, unsuitable, and not in the customers' best interests. Tsamos' customers relied on his advice and routinely followed his recommendations and, as a result, he exercised de facto control over the customers' accounts.
Tsamos' trading in the customer accounts resulted in total trading costs of $958,948, including $849,576 in commissions, and caused over $1.03 million in total realized losses. This is another case of extreme excessive trading that caused substantial harm to customers.
The trading costs and losses in this case are extraordinary. Nearly $960,000 in total trading costs, including over $849,000 in commissions, while customers suffered over $1.03 million in realized losses, demonstrates severe churning. The fact that commission costs alone exceeded $849,000 shows that Tsamos was the primary beneficiary of the trading activity.
Four of the customers were seniors, which makes this violation particularly harmful. Senior investors have limited time to recover from investment losses and often rely on their investment portfolios for retirement income. The over $1 million in losses suffered by Tsamos' customers could have devastating effects on their retirement security.
The pattern is consistent with classic churning: customers relied on Tsamos' advice, routinely followed his recommendations, giving him de facto control, which he abused to generate commissions through excessive trading. The customers lost over $1 million while Tsamos generated over $849,000 in commissions.
For investors, this case reinforces the importance of understanding how your broker is compensated and monitoring account activity. When a broker is compensated primarily through commissions, there is an inherent conflict of interest—the broker earns more by trading more, regardless of whether trading benefits the customer.
Warning signs of excessive trading include: frequent trades that don't align with your investment strategy, high commission costs, trading in and out of similar positions, account value declining despite market gains, and recommendations to trade that the broker cannot clearly explain.
Investors should ask their broker to justify each recommended trade and explain how it serves their investment objectives. If the explanation doesn't make sense or the broker becomes defensive when questioned, it may indicate excessive trading.
The 17-month suspension from October 21, 2024, through March 20, 2026, is a substantial sanction. The fact that no fine was imposed due to Tsamos' financial status is notable given the substantial commissions he generated, suggesting he may have dissipated the commission income.
