When your financial advisor is providing advice they must adhere to the SEC’s Regulation Best Interest (Reg BI) rule and standard of care. Reg BI replaced the former “suitability” rule and created a ‘best interest’ standard for brokerage firms and registered representatives. This standard applies when brokers make recommendations to retail customer for any securities transaction or investment strategy involving securities, including recommendations of types of accounts. This standard applies when brokers make recommendations to retail customer for any securities transaction or investment strategy involving securities, including recommendations of types of accounts.
Next, the advisor must have a reasonable understanding of the specific retail investor’s investment profile. The customer’s profile information generally includes an investor’s financial situation and needs; investments; assets and debts; marital status; tax status; age; investment time horizon; liquidity needs; risk tolerance; investment experience; investment objectives and financial goals; and any other information the retail investor may disclose in connection with the recommendation or advice. The SEC has stated that Reg BI is drawn from fiduciary principles that are common to both brokers and investment advisors including an obligation to act in the investor’s best interest and prohibiting an advisor from placing their own interests ahead of the investor’s. Reg BI comes with different core obligations that brokers must comply with. There is the duty of care obligation requiring financial advisors to form a reasonable belief that their investment advice and recommendations are in the retail investor’s best interest among other duties. In order to do that the broker must evaluate the potential risks, rewards, and costs associated with a product, account type, or series of transactions being recommended.
The care obligation also requires the broker to address the client’s specific needs through obtaining specific investment profile information on the client. The associated person typically will ask the customer for information such as the investor’s risk tolerance or ability to withstand account value declines or increases; experience with investments available; investment objectives and goals; investment time horizon; liquidity needs; assets such as investment accounts held at other financial institutions; tax information; their age and retirement plans; and other information that a customer may want to provide to the advisor to help them to properly address the services needed. Using the foregoing information, the associated person then must consider reasonably available investment option to accomplish the investor’s goals as well as alternative investment options that may be cheaper or other important qualities. Finally, the advisor must conclude that there is a reasonable basis to believe that the recommendation being provided is in the investor’s best interest. An advisor must understand the type of account, securities, and their client in order to meet their care obligations. The type of securities account has the potential to greatly affect retail customers’ costs and investment returns. Different types of securities accounts can offer different features, products, or services, and not all types of accounts or services would be in every investor’s best interest.
