In market structure, we tend to be equity focused, but one of the challenges is liquidity creation. This book examines liquidity creation and regulation. Based on the Baruch College Financial Markets Conference, Liquidity: How to Find it, Regulate it, Get it, this book examines the following questions: Where does liquidity come from? How should liquidity be supplied? What is needed when creating a new platform to provide an environment of liquidity? How do you prepare for liquidity provision concerning market investors, regulatory infrastructure, and technical infrastructure? How do you create liquidity in different asset classes? What is the role of the alternative trading system (ATS) structure within the exchange regulatory framework? What global trends are affecting liquidity creation? Also covered are the popularity of indexing, exchange-traded funds (ETFs) and Robo-advisers (Robos); how technology is transforming liquidity provision, mid and small-cap liquidity provision and new approaches to liquidity creation. An interview with Former Commissioner of the U.S. Securities and Exchange Commission, Michael S. Piwowar is also featured.  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. Much more than historical documents, the transcripts from the conferences are edited for clarity, perspective and context; material and comments from subsequent interviews with the panellists and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.

This open access book addresses four standard business school subjects: microeconomics, macroeconomics, finance and information systems as they relate to trading, liquidity, and market structure. It provides a detailed examination of the impact of trading costs and other impediments of trading that the authors call "frictions". It also presents an interactive simulation model of equity market trading, TraderEx, that enables students to implement trading decisions in different market scenarios and structures. Addressing these topics shines a bright light on how a real-world financial market operates, and the simulation provides students with an experiential learning opportunity that is informative and fun. Each of the chapters is designed so that it can be used as a stand-alone module in an existing economics, finance, or information science course. Instructor resources such as discussion questions, Powerpoint slides and TraderEx exercises are available online.

This book explores the integrity of equity markets, addressing such issues as the exchange vs. customer perspective on price discovery and the ways market participants deal with key regulatory concerns. Do market practitioners pass the integrity test? How does "market integrity" play out globally? What is the overall veracity of the marketplace? These are some of the key questions considered in this volume from the viewpoints of traders, economists, financial market strategists and exchange representative. Titled after the Baruch College Financial Markets Conference, Market Integrity: Do Our Equity Markets Pass the Test?, this book is of interest to market practitioners, trading professionals, academics and students in the field of financial markets.

This book underscores the complexity of the equity markets, the challenges they face, and the fact that they are still a work in process. Three interacting forces drive market change: competition, technology change, and regulatory change. The markets have one major objective in particular to achieve: the delivery of accurate price discovery for both traders and the broader market. Are we getting it? Are competition, technology, and regulation acting together to improve market quality, or are they adding to the complexity of the markets and making accurate price discovery harder to achieve? The difficulty of addressing these issues and reaching a consensus regarding public policy is reflected in the diverse opinions expressed in this book. From an institutional perspective, the volume's contributors highlight the interconnectedness of all aspects of the internal and external environment within which exchange organizations act. Equity Markets in Transition underscores how technological evolution and recent regulatory changes have influenced the business, and how these developments have opened new possibilities for exchange organizations and for equity markets as a whole, including such issues as the impact of equity markets on job creation. The book combines both a theoretical and a practical approach. Part I presents a theoretical overview of the international equity market business, including an overall description of the value chain of stock trading that includes deep dives on every decisive step. Part II contains contributions from various business specialists who have specific practical and academic knowledge of the different steps. Equity Markets in Transition represents a unique combination of theoretical and practical analysis that offers first-hand insights on all relevant interactions and interrelations among the various parts of the exchange business, with an emphasis on facilitating analysis of the status quo and of emerging trends regarding business models, regulation, and the development of the competitor, customer and investor sides.

This book offers a look at equity markets and what they have experienced since the 1997 Order Handling Rules were instituted. Specifically, it examines the tremendous technology innovation, intensified competition between an expanding set of alternative trading venues, and continuing regulatory changes that have occurred. Who have been the key initiators? How has market quality evolved over this period in response? What further structural and regulatory changes are still needed? These are among the key questions addressed in the volume, titled after the Baruch College Financial Markets Conference entitled Rapidly Changing Securities Markets: Who are the Initiators?

In recent years, exchanges on both sides of the Atlantic have been extensively reengineered, and their organizational structures have changed from non-profit, membership organizations to for-profit, demutualized organizations. Concurrently, new alternative trading systems have emerged and the traditional functions of broker/dealer firms have evolved. How have these changes affected the delivery of that mission? How has the efficiency of capital raising in the IPO market been impacted? These are among the key questions addressed in this book, titled after the Baruch College Conference, The Economic Function of a Stock Market. Featuring contributions from a panel of scholars, academicians, policymakers, and industry leaders, this volume examines current issues affecting market quality, including challenges in the marketplace, growth opportunities, and IPO capital raising in the global economy.

Three dominant forces worldwide are driving change today in our financial markets: competition, technology and regulation. But their collective impact in reshaping the markets, though they may be viewed individually as desirable or well-intentioned, is producing challenging results that are difficult to predict, hard to control and not easy to understand. Extreme market turbulence has underlined the key issues as much attention turns to the appropriate regulatory response. That is the backdrop for this thought-provoking book, emerging from a Baruch College Conference on equity market structure in the aftermath of the global financial crisis, and featuring contributions from an acclaimed panel of international scholars, policymakers, regulators, and industry leaders.

The structure and operations of the US equity markets have evolved dramatically in recent decades with the advent of major technology and regulatory changes. Nothing short of a groundbreaking shift has occurred in the securities industry as the transition has been made from predominantly manual, human intermediated trading to predominantly electronic trading. By many measures, commission, spreads and market impact costs have been dramatically reduced in recent years. But does that mean that market quality has improved? That is the key question addressed in this book, titled after the Baruch College Conference, "The Quality of Our Financial Markets: Taking Stock of Where We Stand." Featuring contributions from a distinguished panel of practitioners, academicians, and regulators, this volume offers a penetrating and timely account of the most current issues in market quality, covering such topics as high-frequency trading; the Flash Crash of May 6th, 2010; dark pools; lit pools; fragmentation; disruptive and advanced technologies. And, very significantly, it takes a close look at the impact and influence of regulation.

On April 29, 2003, the Zicklin School of Business hosted a trading conference titled, Coping With Institutional Order Flow. This conference was electronically recorded and later transcribed for this book. The text includes the edited transcript of the panel discussions and separate presentations by two major industry executives, Richard Ketchum' and Robert Mc Sweeney. As with the other volumes in this popular series, this book is not simply intended to be an historical record of the conference. We have edited the manuscript for clarity, perspective and context. New material was gathered in subsequent interviews with many of the panelists. Consequently, some remarks and passages in the text were altered and expanded and many footnotes were introduced. Our goal was to flesh out the dialogue and presentations and to keep the material as contemporary as possible. In doing so, we went to great lengths to preserve the essential nature of the original debate. We worked closely with the panelists in the editing process and took pains not to distort the meaning of their remarks. They have all approved the final draft of the manuscript. We thank them for their assistance and patience. \n my opening remarks at the conference, I suggested that effective handling of institutional order flow is one of the most important and difficult At the time of the conference, Richard Ketchum was President and Deputy Chairman at The Nasdaq Stock Market, Inc. Preface xiv challenges facing our equity markets today.

This book is based on the proceedings of The Electronic Call Auction: New Answers to Old Questions, a conference hosted by the Zicklin School of Business on May 16, 2000. The text includes the edited transcripts of the panel discussions and separate addresses by three major industry executives Douglas M. Atkin, formerly President and CEO, Instinet Corporation; Kenneth D. Pasternak, formerly President and CEO, Knight/Trimark Group, Inc., and William J. Brodsky, Chairman and CEO, Chicago Board Options Exchange. The electronic call auction is an important trading vehicle in many market centers around the world, but is not well understood in the US. What are call auctions? How should they be designed and integrated with continuous trading in a hybrid market structure? As call auctions play a more central role in the US markets, how will they affect market quality in terms of transparency, order flow consolidation, and price discovery? These and other critical questions were asked at the conference while the efficiency of the US markets was broadly assessed.

In the past quarter of a century, the pace of structural change in the equity markets has accelerated dramatically and, as it has, regulation has come to play an increasingly central role in the development of market structure. The purpose of Regulation of U.S. Equity Markets is to consider regulation's contribution to the efficiency of the U.S. equity markets. Sharply different opinions are expressed on the matter, as the discussion ranges from Congressional oversight, to SEC involvement in market structure issues, to the self-regulatory responsibilities of the market centers, most notably, the New York Stock Exchange and the Nasdaq Stock Market.

This book considers how the inclusion of electronic call auction trading would affect the performance of our U.S. equity markets. The papers it contains focus on the call auction and its role in a hybrid market structure. The purpose is to increase understanding of this trading environment, and to consider the design of a more efficient stock market. A call auction is a form of trading that died out in the pre-computer age but is making its reentrance today as an electronic marketplace. Batching orders for simultaneous execution at a single moment in time at a single price is the essence of call auction trading. Because its determination is based on the full set of orders, the clearing price in a call auction can be thought of as a 'consensus value.' This contrasts with a continuous market where a transaction is made any time a buy and sell order meet in price, and where price generally fluctuates as the orders meet. Recent advances in computer technology have considerably expanded the call auction's functionality.We suggest that the problems we are facing concerning liquidity, volatility, fragmentation and price discovery are largely endemic to the continuous market, and that the introduction of electronic call auction trading in the U.S. would be the most important innovation in market structure that could be made. This book had its origin in a symposium, Electronic Call Market Trading, that was held at New York University's Salomon Center on April 20, 1995. At the time, three proprietary trading systems based on call auction principles (The Arizona Stock Exchange, Posit, and Instinet's Crossing Network) had been operating for several years and interest already existed in the procedure. Since the symposium, increasing use has been made of call auctions, primarily by the ParisBourse in its Nouveau Marchi and CAC markets, by Deutsche Borse in its Xetra market, and for fixed income in the U.S. by State Street's BondConnect.Rather than being used as stand alone systems, however, call auctions are now being interfaced with continuous markets so as to produce hybrid market structures, a development to which considerable attention is given in a number of the chapters in this book. The book is divided into three parts. * The first, Call Auction Trading, gives an overview of this trading environment. * The second, Investor Trading Practices and the Demand for Immediacy, contains the findings of four institutional trader surveys. * The third, Market Structure: The Broader Picture, presents a more inclusive view of the development of market structure.

The skin, uniquely positioned at the interface between the human body and the external world, plays a multifaceted role in the expression of cancer. Primary skin cancer is the most common cancer afflicting mankind and is rising in inci dence, despite the fact that it is often preventable. Besides primary cancer, the skin may show direct and indirect evidence of internal cancer, thus serving as a window to the body for both laymen and physicians alike. In addition, the acces sibility of the skin is useful for the study of carcinogenesis as well as cancer treat ment options. lowe much of my interest in skin cancer to Dr. Leon Goldman, the father of dermatologic laser surgery, and to Dr. Edmund Klein, the father of modern immunotherapy. We, at the Roswell Park Memorial Institute, were indeed for tunate to have a wealth of patients available for study.

This book is an augmented account of Technology and Regulation: How Are They Driving Our Markets?, a conference hosted by the Zicklin School of Business at Baruch College on May 1, 2007. The text includes the edited transcript of the full conference: four panels and the major presentations of three distinguished industry leaders - Ian Domowitz, Managing Director, ITG, Inc.; Erik Sirri, Director of the Division of Market Regulation, US Securities and Exchange Commission; and John Thain, who was CEO of NYSE Euronext at the time of the conference. The book also includes a related paper by Paul Davis, Mike Pagano, and myself: "Divergent Expectations," Journal of Portfolio Management, Fall 2007. My co-editors and I have worked diligently to make this book, like all the other popular books in the series, more than an historical record. John Byrne, Antoinette Colaninno and I have edited the manuscript heavily for clarity and unity of ideas.

This book is based on A Trading Desk's View of Market Quality, a conference hosted by the Zicklin School of Business on April 30, 2002. The text includes the edited transcripts of each panel as well as separate presentations by two distinguished industry officials, Joel Steinmetz, who at the time was Senior Vice President, Equities, Instinet Corporation, and Laura Unger, formerly Acting Chairperson and Commissioner of the U.S. Securities and Exchange Commission. This book is not simply a historical record of the conference. It is also an exposition of the complex issues raised by the industry experts and speakers in attendance. Therefore, we introduced new material from foll- up interviews with many of the panelists so that the final result would be a more valuable document. Our intention was to examine the discussions with a critical eye, then modify or expand various sections to reflect contemporary conditions. In addition, we have included a paper by Ozenbas, Schwartz and Wood (see Chapter 8, page 151) that provides further analysis on the connection between market quality and intra-day 1 volatility that was noted several times during the conference. During the production process, we worked with the panelists, and took pains not to put words in their mouths. They have all approved the final draft of the manuscript, and we thank them for their assistance and patience.

Volatility is very much with us in today's equity markets. Day-to-day price swings are often large and intra-day volatility elevated, especially at market openings and closings. What explains this? What does this say about the quality of our markets? Can short-period volatility be controlled by better market design and a more effective use of electronic technology? Featuring insights from an international array of prominent academics, financial markets experts, policymakers and journalists, the book addresses these and other questions concerning this timely topic. In so doing, we seek deeper knowledge of the dynamic process of price formation, and of the market structure and regulatory environment within which our markets function.

Competition between market centers is a driving force for innovation, dynamic growth, and reasonable pricing structures. Consolidating the order flow amasses liquidity, sharpens price discovery, and lowers trading costs. This book addresses such timely topics as the impact of technology on financial markets and includes contributions from prominent academics, policymakers and professionals in the field. It is the latest title in established conference proceedings series.

Specialists and floor brokers, in direct contact on the trading floor, are at the heart of operations at the national U.S. equity exchanges. At the other end of the spectrum, electronic trading platforms characterize most other equity markets globally. Why have we not followed the international trend, and should we? Can the unique services offered by the floor be provided as effectively in an electronic environment? Which environment would institutional and retail traders each find most suitable to their special needs? These are some of the questions that will be addressed. In so doing, Electronic vs. Floor Based Trading will provide perspective on the future direction that exchange market structure is likely to follow in the coming years.
