The research conducted by SLCG on "How Widespread and Predictable is Stock Broker Misconduct?" revealed that prior customer complaints against individual brokers can be indicative of future complaints. McCann, Qin, and Yan's findings indicate that including the complaint histories of co-workers significantly improves the ability to predict complaints against brokers who have not previously been complained about. They also concluded that customer complaints that were denied - not just settlements and awards - can effectively forecast future investor harm.

In their study, Egan, Matvos, and Seru confirm that the regulatory and labor market mechanisms do not effectively filter out poor brokers from the industry. Instead, they steer these brokers over time towards brokerage firms that employ individuals with a disproportionately high incidence of customer complaints. These firms are characterized by lax hiring practices and relaxed compliance ethics, targeting less sophisticated investors.

Dimmock et al. [2016] in a related study find that financial fraud is contagious. They find that a broker's propensity to commit financial fraud is significantly influenced by his or her coworkers' propensity to commit fraud after controlling for firm culture, branch atmosphere, market conditions and state regulatory environment.

Raymond Guillermo Ariass current employer, is one of the 30 highest risk brokerage firms measured by the percent of brokers at the firm who have customer complaints disclosed on their BrokerCheck reports. 13.40% of 's brokers have customer complaints compared to only 2.71% of all brokers who have complaints.
