Losses on Concentrated Positions: What Can Investors Do?

Concentration or “failure to diversify” is a securities violation that occurs when a financial professional concentrates an investor’s assets in one particular investment, class of investments, or market sector. Holding large concentrated stock or investment positions may pose significant downside risks for investors. 

Brokerage firms and their registered financial professionals have a responsibility to ensure that their customers understand the risks associated with concentration, and to disclose and recommend the risk management strategies which can be used to protect the value of the concentrated portfolio.

When full-service brokerage firms and their advisors recommend concentrated positions, they can be held liable in FINRA arbitration claims.

What is Regulation Best Interest (“Reg BI”)? 

SEC Regulation Best Interest, a/k/a “Reg BI” establishes a “best interest” standard of conduct for brokers and brokerage firms making recommendations of securities investments and investment strategies to their customers, under the Securities Exchange Act of 1934. 

Under Reg BI, investment advisors and their firms have a responsibility to make recommendations with their customer’s best interest in mind, based upon the client’s personal needs and preferences. Additionally, a representative that recommends investments for the purpose of being compensated through increased commissions, and enriches themselves rather than benefiting the client, is violating securities laws

Brokers and financial advisors must consider an investment’s risk, ensure that they do not misrepresent material facts, and/or overconcentrate the customer’s portfolio. Further, financial professionals and their firms cannot disregard a customer’s risk-tolerance when making unsuitable investment recommendations.
