"The process by which securities are traded is very different from the idealized picture of a frictionless and self-equilibrating market offered by the typical finance textbook. This book offers a more accurate and authoritative take on this process. The book starts from the assumption that not everyone is present at all times simultaneously on the market, and that participants have quite diverse information about the security's fundamentals. As a result, the order flow is a complex mix of information and noise, and a consensus price only emerges gradually over time as the trading process evolves and the participants interpret the actions of other traders. Thus, a security's actual transaction price may deviate from its fundamental value, as it would be assessed by a fully informed set of investors. The book takes these deviations seriously, and explains why and how they emerge in the trading process and are eventually eliminated. The authors draw on a vast body of theoretical insights and empirical findings on security price formation that have come to form a well-defined field within financial economics known as "market microstructure." Focusing on liquidity and price discovery, the book analyzes the tension between the two, pointing out that when price-relevant information reaches the market through trading pressure rather than through a public announcement, liquidity may suffer. It also confronts many striking phenomena in securities markets and uses the analytical tools and empirical methods of market microstructure to understand them. These include issues such as why liquidity changes over time and differs across securities, why large trades move prices up or down, and why these price changes are subsequently reversed, and why we observe temporary deviations from asset fair values"--

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 rictions 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 effect of liquidity on asset prices, liquidity variations over time and how liquidity risk affects prices.

Brings together today's best financial minds across the world to discuss the issue of liquidity in today's markets. It is often proxied by trade-based measures (such as trading volume, frequency of trading, dollar value of shares trade, etc), order based measures and price impact measures.

This book is among the first to present the mathematical models most commonly used to solve optimal execution problems and market making problems in finance. The Financial Mathematics of Market Liquidity: From Optimal Execution to Market Making presents a general modeling framework for optimal execution problems-inspired from the Almgren-Chriss app

Whether you are an investment professional managing billions of dollars or an individual investor with a small nest egg, TrimTabs Investing shows you how to beat the major stock market averages with less risk. This groundbreaking book begins by comparing the stock market to a casino in which the house (public companies and the insiders who run them) buys and sells shares with the players (institutional and individual investors). TrimTabs Investing argues that stock prices are primarily a function of liquidity—the amount of shares available for purchase and the amount of money available to buy them—rather than fundamental value. Finally, it outlines the building blocks of liquidity theory and explains how you can use them to predict the direction of the stock market. “Charles Biderman, a savvy and battle-scarred veteran of the investment wars, has fashioned an intriguing approach to making money in the stock market that adroitly avoids both heavy-breathing speculation and the standard Wall Street practices that enable investors, big and small, to lose money in good markets as well as bad. Aimed at the sophisticated investor (which may or may not be an oxymoron), the book is written in blessedly straightforward prose and is a worthwhile read for anyone with an urge to have a fling at investing.--Alan Abelson Barron’s “Since the days of Joseph and Pharaoh, it has been axiomatic that the size of the grain harvest affects the level of grain prices; but today’s investors have been slow to appreciate the fact that the supply of stock shares significantly determines the level of stock prices. Biderman’s long overdue book outlines the theory and evidence behind ‘Trading Float,’ the actual—and exploitable—power behind major moves in the stock market. --Paul Montgomery CEO and CIO of Montgomery Capital Management “‘Trade as corporate execs do, not as they say.’ Charles Biderman has built an impressive list of hedge fund clients from this essential insight, and this book does a great job explaining exactly how retail investors can incorporate it into their investing.” --Eric Zitzewitz Assistant Professor of Economics, Stanford Graduate School of Business “Charles Biderman is a smart thinker, clear writer—and he offers here some very interesting ideas. This book is for the little guy who enjoys reading about money and economics, even if he doesn’t adopt the strategies offered here; and for the professional or sophisticated investor, who, to a greater or lesser degree, just might.--Andrew Tobias author of The Only Investment Guide You'll Ever Need
