Sec Investigations And Securities Class Actions: An Empirical Comparison, Stephen J. Choi, Adam C. Pritchard

Articles

Using actions with both an SEC investigation and a class action as our baseline, we compare the targeting of SEC-only investigations with class-action-only lawsuits. Looking at measures of information asymmetry, we find that investors in the market perceive greater information asymmetry following the public announcement of the underlying violation for class-action-only lawsuits compared with SEC-only investigations. Turning to sanctions, we find that the incidence of top officer resignation is greater for class-action-only lawsuits relative to SEC-only investigations. Our findings are consistent with the private enforcement targeting disclosure violations at least as precisely as (if not more so than) SEC enforcement.
