In their study "How Widespread and Predictable is Stock Broker Misconduct?" researchers at SLCG discovered that past customer complaints against individual brokers can indicate the likelihood of future complaints. McCann, Qin, and Yan also found that incorporating co-workers' complaint histories notably enhances the predictive accuracy for brokers without prior complaints. Furthermore, they determined that customer complaints that were denied - beyond just settlements and awards - are valuable in forecasting potential investor harm.

Egan, Matvos and Seru's results confirm that, rather than weeding bad brokers out of the industry, the regulatory environment and labor market sifts bad brokers down the quality ladder over time into brokerage firms who employ brokers with disproportionately higher numbers of customer complaints. These high-risk brokerage firms have loose hiring practices and lax compliance ethics and specialize in preying on unsophisticated investors.

Dimmock et al. [2016], in a related study, discover that financial fraud exhibits contagious behavior. They reveal that a broker's likelihood of engaging in financial fraud is notably affected by the propensity of their colleagues to commit fraud, even after adjusting for firm culture, branch environment, market conditions, and state regulatory oversight.

Warren Alan Marmorsteins 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. 16.00% of 's brokers have customer complaints compared to only 2.71% of all brokers who have complaints.
