Download or read book Effective Vs Efficient Securities in Arbitrage Free Markets with Bid Ask Spreads written by Mariagiovanna Baccara and published by . This book was released on 2009 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We consider a securities market with bid-ask spreads at any period, including liquidation. Although the minimum-cost super-replication problem is non-linear, we introduce an auxiliary problem that allows us to characterize no-arbitrage via linear programming techniques. Since no-arbitrage per se does not bound the bid-ask spread of a newly traded security, we introduce the notion of effective new security. We show that effectiveness restricts the no-arbitrage bid and ask prices of a new security to the interval defined by the minimum-cost problem. We discuss in details the cases in which the boundaries of this interval can be reached without violating no-arbitrage. We also compare effectiveness to efficiency as discussed in Jouini and Kallal (2001). We show that effectiveness is not sufficient for efficency, but is equivalent to the weaker notion of zero inefficiency cost.
Download or read book Arbitrage Risk and Market Efficiency Applications to Securities Class Actions written by Rajeev R. Bhattacharya and published by . This book was released on 2017 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring the efficiency of the market for a stock is important for a number of reasons, but such measurements have been widely utilized in securities class action litigation, particularly to justify certification of cases as appropriate for class action treatment. We provide a general methodology to measure the arbitrage risk, which is a negative proxy for the market efficiency, of a stock for any relevant period. We apply this methodology to calculate the arbitrage risk of each U.S. exchange-listed common stock for every calendar year from 1988 to 2010. We find that market efficiency is significantly affected by turnover (negatively), the number of market makers for Nasdaq stocks (negatively), and serial correlation in the Capital Asset Pricing Model of the stock (positively). These findings seem inconsistent with “conventional wisdom” and with the understanding that courts use in applying notions of market efficiency to class certification decisions, but we show that our findings are consistent with economic logic. The relations between market efficiency and market capitalization (positive), bid-ask spread (negative) and institutional ownership (positive) are consistent with conventional wisdom. The impact on market efficiency of the number of securities analysts following a stock and the public float ratio of a stock are of ambiguous significance.

Download or read book Measuring Liquidity in Financial Markets written by Abdourahmane Sarr and published by International Monetary Fund. This book was released on 2002-12 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper provides an overview of indicators that can be used to illustrate and analyze liquidity developments in financial markets. The measures include bid-ask spreads, turnover ratios, and price impact measures. They gauge different aspects of market liquidity, namely tightness (costs), immediacy, depth, breadth, and resiliency. These measures are applied in selected foreign exchange, money, and capital markets to illustrate their operational usefulness. A number of measures must be considered because there is no single theoretically correct and universally accepted measure to determine a market's degree of liquidity and because market-specific factors and peculiarities must be considered.

Available in PDF, EPUB and Kindle. Book excerpt: The Efficient Market Hypothesis believes that it is impossible for an investor to outperform the market because all available information is already built into stock prices. However, some anomalies could persist in stock markets while some other anomalies could appear, disappear and re-appear again without any warning. A Special Issue on "Efficiency and Anomalies in Stock Markets" will be devoted to advancements in the theoretical development of market efficiency and anomaly in the Stock Market, as well as applications in Stock Market efficiency and anomalies.
Download or read book Trading and Electronic Markets What Investment Professionals Need to Know written by Larry Harris and published by CFA Institute Research Foundation. This book was released on 2015-10-19 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The true meaning of investment discipline is to trade only when you rationally expect that you will achieve your desired objective. Accordingly, managers must thoroughly understand why they trade. Because trading is a zero-sum game, good investment discipline also requires that managers understand why their counterparties trade. This book surveys the many reasons why people trade and identifies the implications of the zero-sum game for investment discipline. It also identifies the origins of liquidity and thus of transaction costs, as well as when active investment strategies are profitable. The book then explains how managers must measure and control transaction costs to perform well. Electronic trading systems and electronic trading strategies now dominate trading in exchange markets throughout the world. The book identifies why speed is of such great importance to electronic traders, how they obtain it, and the trading strategies they use to exploit it. Finally, the book analyzes many issues associated with electronic trading that currently concern practitioners and regulators.
Download or read book Liquidity and Asset Prices written by Yakov Amihud and published by Now Publishers Inc. This book was released on 2006 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquidity and Asset Prices reviews the literature that studies the relationship between liquidity and asset prices. The authors review the theoretical literature that predicts how liquidity affects a security's required return and discuss the empirical connection between the two. Liquidity and Asset Prices surveys the theory of liquidity-based asset pricing followed by the empirical evidence. The theory section proceeds from basic models with exogenous holding periods to those that incorporate additional elements of risk and endogenous holding periods. The empirical section reviews the evidence on the liquidity premium for stocks, bonds, and other financial assets.
Download or read book The Efficient Market Theory and Evidence written by Andrew Ang and published by Now Publishers Inc. This book was released on 2011 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Efficient Market Hypothesis (EMH) asserts that, at all times, the price of a security reflects all available information about its fundamental value. The implication of the EMH for investors is that, to the extent that speculative trading is costly, speculation must be a loser's game. Hence, under the EMH, a passive strategy is bound eventually to beat a strategy that uses active management, where active management is characterized as trading that seeks to exploit mispriced assets relative to a risk-adjusted benchmark. The EMH has been refined over the past several decades to reflect the realism of the marketplace, including costly information, transactions costs, financing, agency costs, and other real-world frictions. The most recent expressions of the EMH thus allow a role for arbitrageurs in the market who may profit from their comparative advantages. These advantages may include specialized knowledge, lower trading costs, low management fees or agency costs, and a financing structure that allows the arbitrageur to undertake trades with long verification periods. The actions of these arbitrageurs cause liquid securities markets to be generally fairly efficient with respect to information, despite some notable anomalies.
Download or read book Broken Markets written by Sal Arnuk and published by FT Press. This book was released on 2012-05-22 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The markets have evolved at breakneck speed during the past decade, and change has accelerated dramatically since 2007's disastrous regulatory "reforms." An unrelenting focus on technology, hyper-short-term trading, speed, and volume has eclipsed sanity: markets have been hijacked by high-powered interests at the expense of investors and the entire capital-raising process. A small consortium of players is making billions by skimming and scalping unaware investors -- and, in so doing, they've transformed our markets from the world's envy into a barren wasteland of terror. Since these events began, Themis Trading's Joe Saluzzi and Sal Arnuk have offered an unwavering voice of reasoned dissent. Their small brokerage has stood up against the hijackers in every venue: their daily writings are now followed by investors, regulators, the media, and "Main Street" investors worldwide. Saluzzi and Arnuk don't take prisoners! Now, in Broken Markets, they explain how all this happened, who did it, what it means, and what's coming next. You'll understand the true implications of events ranging from the crash of 1987 to the "Flash Crash" -- and discover what it all means to you and your future. Warning: you will get angry (if you aren't already). But you'll know exactly why you're angry, who you're angry at, and what needs to be done!

Download or read book Market Liquidity written by Thierry Foucault and published by Oxford University Press. This book was released on 2023 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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"--

Download or read book The New Stock Market written by Merritt B. Fox and published by Columbia University Press. This book was released on 2019-01-08 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. stock market has been transformed over the last twenty-five years. Once a market in which human beings traded at human speeds, it is now an electronic market pervaded by algorithmic trading, conducted at speeds nearing that of light. High-frequency traders participate in a large portion of all transactions, and a significant minority of all trade occurs on alternative trading systems known as “dark pools.” These developments have been widely criticized, but there is no consensus on the best regulatory response to these dramatic changes. The New Stock Market offers a comprehensive new look at how these markets work, how they fail, and how they should be regulated. Merritt B. Fox, Lawrence R. Glosten, and Gabriel V. Rauterberg describe stock markets’ institutions and regulatory architecture. They draw on the informational paradigm of microstructure economics to highlight the crucial role of information asymmetries and adverse selection in explaining market behavior, while examining a wide variety of developments in market practices and participants. The result is a compelling account of the stock market’s regulatory framework, fundamental institutions, and economic dynamics, combined with an assessment of its various controversies. The New Stock Market covers a wide range of issues including the practices of high-frequency traders, insider trading, manipulation, short selling, broker-dealer practices, and trading venue fees and rebates. The book illuminates both the existing regulatory structure of our equity trading markets and how we can improve it.
