<p>In 1975, the U.S. Securities Acts Amendments were enacted by Congress, which amongst other measures, officially mandated development of a National Market System (NMS). Since that time, the competitive map has been redrawn, technological changes have been huge and pervasive in scope, and the landscape is ever-changing. This book looks at the evolution of NMS and the factors that have influenced it since its development. Titled after the Baruch College Financial Markets Conference, <i>40 Years of Experience with the National Market System (NMS): Who Are the Winners and What Have We Learned,</i> the book examines the following questions: <i>What is liquidity and how is it best measured and provided? Has NMS-Induced competition delivered? What is technology’s challenge to regulators? Are fair and level playing fields a good regulatory goal? What is the buyside’s view?</i></p><p>The Zicklin School of Business Financial Markets Series presents the insights emerging from a sequence of conferences hosted by the Zicklin School at Baruch College for industry professionals, regulators, and scholars. The transcripts from the conferences are edited for clarity, perspective and context; material and comments from subsequent interviews with the panelists and speakers are integrated for a complete thematic presentation. Each book is focused on a well delineated topic, but all deliver broader insights into the quality and efficiency of the U.S. equity markets and the dynamic forces changing them.</p>
