An advisor’s duty of care requires recommendations and accepted orders to be suitable for the client based on know-your-client information, investment objectives, time horizon, risk tolerance, financial circumstances, and investment knowledge. Even when a client requests a trade, the advisor cannot ignore suitability obligations. If the order is unsuitable, the advisor must warn the client, document the concern, and may be required to refuse or escalate the transaction depending on firm policy and regulatory obligations. Compliance refers to following laws and internal rules, but the core ethical breach in this scenario is failing to protect the client’s interests. Integrity involves honesty, and professionalism involves proper conduct. The direct violation is the advisor’s duty of care.
