Brokers with a history of misconduct are far more likely to harm investors. The firms who employ the most brokers that harm investors remain the same year to year. These trends are well known to regulators, who have instituted a variety of monitoring and enforcement measures to protect investors from high-risk brokers. In 2018, FINRA issued notices and revised rules to strengthen its oversight of high-risk brokers and firms. Panelists from FINRA and state regulatory agencies will discuss the problems and progress in these efforts to rein in recidivist brokers.
