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 research underscores that, rather than eliminating underperforming brokers from the industry, the regulatory environment and labor market tend to funnel these brokers towards firms that hire individuals with disproportionately high numbers of customer complaints. These firms typically maintain loose hiring criteria and exhibit lenient compliance standards, specializing in exploiting inexperienced investors.

Dimmock et al. [2016], in a related research endeavor, uncover that financial fraud spreads like a contagion. They ascertain that the likelihood of a broker engaging in financial fraud is significantly affected by the predisposition of their coworkers toward fraudulent behavior, even when accounting for firm culture, branch environment, market conditions, and state regulatory frameworks.
