Securities litigators represent individuals and corporations in securities class actions, stock-drop cases, and derivative actions. The work is in some ways similar to criminal defense work, determining what your client has done, whether it violates securities regulations, and how to defend the case. Securities litigators perform internal investigations on behalf of corporate audit committees and represent those audit committees, individuals, and companies in SEC investigations. Securities litigators also advise corporations on director and officer liability insurance issues. The cases can be complicated and involve complex facts patterns; practitioners will spend a lot of time reviewing documents and interviewing witnesses to develop the facts.
