Conflict of interest rules require disclosure and equitable resolution by intermediaries to protect investor interests and market integrity. Intermediaries must prioritise investor protection by providing tailored, competent advice, maintaining high standards of integrity and professionalism, exercising due diligence and independent judgment, avoiding collusion, and notifying clients of fee changes. They must make clear, timely and non-misleading disclosures, protect client confidentiality subject to legal exceptions, and implement internal controls, recordkeeping and data backup. Intermediaries must disclose and manage conflicts of interest, be prohibited from insider trading, refrain from market manipulation or unfair competition, cooperate with regulators, and inform clients of material changes affecting their interests.
