Securities Litigation LITIGATION/CONTROVERSY

We defend federal and state securities claims against entities and individuals, and derivative and other claims against corporations and their officers and directors. These claims address areas such as prospectus and other disclosure obligations, restatements, mutual fund trading and marketing, broker-dealer duties to clients and counter-parties, fiduciary duties and insider trading. Many of the over 300 securities class actions that we have defended have been for technology companies (including high-tech, biotech and pharmaceutical companies). We also have substantial experience in representing investment banks, broker-dealers and other securities industry participants, investment advisory and mutual fund companies, life insurance and other financial services firms, REITs, and retailers. In recent matters, our lawyers have:

  • Defended mutual fund advisers in the consolidated Market Timing multidistrict litigation (MDL) proceedings, class and institutional investor claims regarding investment advisor fees, and class actions concerning mutual fund marketing practices
  • Taken a leadership role in the defense of over 300 consolidated securities class actions—the IPO Laddering Litigation—and separately obtained the dismissal of class actions against an underwriter challenging IPO allocations and alleged IPO flipping
  • Represented an investment bank in its successful appeal to the Second Circuit of a $164.5 million jury verdict for losses sustained in a nondiscretionary currency trading account
