For the past four decades, U.S. government prosecution of insider trading has been a top priority. In this presentation, Professor Steinberg focuses on the ambiguity of US Law and its application in two seminal cases in which he served as an expert witness — the criminal prosecution of Martha Stewart and the US Securities and Exchange Commission (SEC) enforcement proceeding against Mark Cuban. Compared to the Australian, European Union and Hong Kong frameworks, the US regimen has unacceptable ambiguity, doctrine and application — all too often resulting in disparate treatment of similarly situated persons. In this presentation, Professor Steinberg, a former SEC enforcement attorney, will address the current status of insider trading law in the US from both historical and contemporary perspectives. For scholarship by Professor Steinberg on insider trading, see, e.g., Insider Trading (3d edition Oxford Univ. Press 2010) (coauthored); Securities and Exchange Commission v. Cuban — A Trial of Insider Trading (Twelve Tables Press 2019). Professor Steinberg is the editor-in-chief of The International Lawyer published by the International Law Section of the American Bar Association.
