Available in PDF, EPUB and Kindle. Book excerpt: This paper offers a model in which asset prices reflect both covariance risk and misperceptions of firmsapos prospects, and in which arbitrageurs trade against mispricing. In equilibrium, expected returns are linearly related to both risk and mispricing measures (e.g., fundamental/price ratios). With many securities, mispricing of idiosyncratic value components diminishes but systematic mispricing does not. The theory offers untested empirical implications about volume, volatility, fundamental/price ratios, and mean returns, and is consistent with several empirical findings. These include the ability of fundamental/price ratios and market value to forecast returns, and the domination of beta by these variables in some studies.

Available in PDF, EPUB and Kindle. Book excerpt: The present 'Introductory Lectures on Arbitrage-based Financial Asset Pricing' are a first attempt to give a comprehensive presentation of Arbitrage Theory in a discrete time framework (by the way: all the re sults given in these lectures apply to a continuous time framework but, probably, in continuous time we could achieve stronger results - of course at the price of stronger assumptions). It has been turned out in the last few years that capital market theory as derived and evolved from the capital asset pricing model (CAPM) in the middle sixties, can, to an astonishing extent, be based on arbitrage arguments only, rather than on mean-variance preferences of investors. On the other hand, ar bitrage arguments provided access to a wider range of results which could not be obtained by standard CAPM-methods, e. g. the valuation of contingent claims (derivative assets) Dr the_ investigation of futures prices. To some extent the presentation will loosely follow historical lines. A selected set of capital asset pricing models will be derived according to their historical progress and their increasing complexity as well. It will be seen that they all share common structural properties. After having made this observation the presentation will become an axiomatical one: it will be stated in precise terms what arbitrage is about and what the consequences are if markets do not allow for risk-free arbitrage opportunities. The presentation will partly be accompanied by an illus trating example: two-state option pricing.
Download or read book Arbitrage Pricing and the Existence of Equilibrium Under Portfolio Constraints written by Dong Chul Won and published by . This book was released on 2003 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Market frictions create portfolios of complicated nature, constrained zero-income portfolios. They generate no income in the future contingencies but matter to risk sharing whether they are mispriced or not. The no arbitrage conditions of the literature may not be qualified for equilibrium conditions in the presence of constrained zero-income portfolios. Thus 'pricing by arbitrage' is far from completely characterizing asset pricing relations. The purpose of this paper is to provide a unified treatment of both asset pricing and equilibrium when asset markets are subject to portfolio constraints. In particular, 'projective arbitrage' is proposed to examine both asset pricing and the existence of equilibrium under portfolio constraints. To formulate the effect of constrained zero-income portfolios on asset pricing and equilibrium, we introduce the local and global laws of one price as an extension of the law of one price to the case with portfolio constraints. The global law of one price is identified as 'pricing by projective arbitrage.' Moreover, the global law of one price provides an important criterion for judging the capability of various notions of arbitrage to characterize equilibrium asset prices under portfolio constraints. The traditional approach to general equilibrium with incomplete markets breaks down in the face of market frictions simply because the law of one price fails.
Download or read book A Note on Arbitrage Asset Pricing written by Manfred Steiner and published by . This book was released on 1999 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arbitrage pricing plays an important role in asset valuation. The most applications of arbitrage asset pricing theories are based on the law of one price or asymptotic arbitrage free markets. We provide some new results on arbitrage and especially the arbitrage pricing theory by distinguishing between the absence of arbitrage, the law of one price and the absence of riskless arbitrage. Then we find the implications of these conditions for arbitrage asset pricing. Since the three concepts of the absence of arbitrage imply that the linear functionals that give the mean and the cost of a portfolio are continuous, hence there exist unique portfolios that represent these functionals. We detect a positive distance between these portfolios and therefore between the functionals. Thus the law of one price and the absence of a riskless arbitrage opportunity lead to systematic mispricing if both the contingent claims and the assets are mispriced. The beta pricing literature usually makes strong assumptions to obtain exact asset pricing. This belongs to a debate over which factors have the best theoretical or empirical justification. In the light of our results it is more advisable to acknowledge that almost only approximate arbitrage asset pricing can be obtained. The introduction of risky arbitrage opportunities in the sense that there might be an arbitrage opportunity with positive probability but not with probability one requires the knowledge of the risk aversion of investors. Therefore exact asset pricing can only be obtained by equilibrium asset pricing models. Our results generalizes to other arbitrage asset pricing theories like the Black and Scholes option valuation model and even the Modigliani-Miller Theorem.

Book excerpt: Diploma Thesis from the year 1996 in the subject Business economics - Banking, Stock Exchanges, Insurance, Accounting, grade: 1,3, European Business School - International University Schlo Reichartshausen Oestrich-Winkel, 160 entries in the bibliography, language: English, abstract: A "few surprises" could be the trivial answer of the Arbitrage Pricing Theory if asked for the major determinants of stock returns. The APT was developed as a traceable framework of the main principles of capital asset pricing in financial markets. It investigates the causes underlying one of the most important fields in financial economics, namely the relationship between risk and return. The APT provides a thorough understanding of the nature and origins of risk inherent in financial assets and how capital markets reward an investor for bearing risk. Its fundamental intuition is the absence of arbitrage which is, indeed, central to finance and which has been used in virtually all areas of financial study. Since its introduction two decades ago, the APT has been subject to extensive theoretical as well as empirical research. By now, the arbitrage theory is well established in both respects and has enlightened our perception of capital markets. This paper aims to present the APT as an appropriate instrument of capital asset pricing and to link its principles to the valuation of risky income streams. The objective is also to provide an overview of the state of art of APT in the context of alternative capital market theories. For this purpose, Section 2 describes the basic concepts of the traditional asset pricing model, the CAPM, and indicates differences to arbitrage theory. Section 3 constitutes the main part of this paper introducing a derivation of the APT. Emphasis is laid on principles rather than on rigorous proof. The intuition of the pricing formula and its consistency with the state space preference theory are discussed. Important contributions to the APT are classified and br

Available in PDF, EPUB and Kindle. Book excerpt: 1. Main Goals The theory of asset pricing has grown markedly more sophisticated in the last two decades, with the application of powerful mathematical tools such as probability theory, stochastic processes and numerical analysis. The main goal of this book is to provide a systematic exposition, with practical appli cations, of the no-arbitrage theory for asset pricing in financial engineering in the framework of a discrete time approach. The book should also serve well as a textbook on financial asset pricing. It should be accessible to a broad audi ence, in particular to practitioners in financial and related industries, as well as to students in MBA or graduate/advanced undergraduate programs in finance, financial engineering, financial econometrics, or financial information science. The no-arbitrage asset pricing theory is based on the simple and well ac cepted principle that financial asset prices are instantly adjusted at each mo ment in time in order not to allow an arbitrage opportunity. Here an arbitrage opportunity is an opportunity to have a portfolio of value aat an initial time lead to a positive terminal value with probability 1 (equivalently, at no risk), with money neither added nor subtracted from the portfolio in rebalancing dur ing the investment period. It is necessary for a portfolio of valueato include a short-sell position as well as a long-buy position of some assets.
Download or read book A Behavioral Approach to Asset Pricing written by Hersh Shefrin and published by Elsevier. This book was released on 2005-02-03 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Behavioral Approach to Asset Pricing Theory examines the reigning assumptions of asset pricing theory and reconstructs them to incorporate findings from behavioral finance. It constructs a solid, intact structure that challenges classic assumptions and at the same time provides a strong theory and efficient empirical tools. Building on the models developed by both traditional asset pricing theorists and behavioral asset pricing theorists, this book takes the discussion to the next step. The author provides a general behaviorally based intertemporal treatment of asset pricing theory that extends to the discussion of derivatives, fixed income securities, mean-variance efficient portfolios, and the market portfolio. The book develops a series of examples to illustrate the theoretical results. The CD-ROM contains most of the examples, worked out as Excel spreadsheets, so that a diligent reader can follow them through. Instructors might also want to use the examples to assign class exercises, asking students to modify the numbers and see what happens. * The first book to focus completely on how behavioral finance principles affect asset pricing * Hersh Shefrin is a recognized expert in behavioral finance * Behavioral finance is a growth area in finance scholarship and moving more and more into practice
Download or read book Asset Pricing Theory written by Costis Skiadas and published by Princeton University Press. This book was released on 2009-02-09 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asset Pricing Theory is an advanced textbook for doctoral students and researchers that offers a modern introduction to the theoretical and methodological foundations of competitive asset pricing. Costis Skiadas develops in depth the fundamentals of arbitrage pricing, mean-variance analysis, equilibrium pricing, and optimal consumption/portfolio choice in discrete settings, but with emphasis on geometric and martingale methods that facilitate an effortless transition to the more advanced continuous-time theory. Among the book's many innovations are its use of recursive utility as the benchmark representation of dynamic preferences, and an associated theory of equilibrium pricing and optimal portfolio choice that goes beyond the existing literature. Asset Pricing Theory is complete with extensive exercises at the end of every chapter and comprehensive mathematical appendixes, making this book a self-contained resource for graduate students and academic researchers, as well as mathematically sophisticated practitioners seeking a deeper understanding of concepts and methods on which practical models are built. Covers in depth the modern theoretical foundations of competitive asset pricing and consumption/portfolio choice Uses recursive utility as the benchmark preference representation in dynamic settings Sets the foundations for advanced modeling using geometric arguments and martingale methodology Features self-contained mathematical appendixes Includes extensive end-of-chapter exercises

This book was released on 2018-12-29 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book mainly addresses the general equilibrium asset pricing method in two aspects: option pricing and variance risk premium. First, volatility smile and smirk is the famous puzzle in option pricing. Different from no arbitrage method, this book applies the general equilibrium approach in explaining the puzzle. In the presence of jump, investors impose more weights on the jump risk than the volatility risk, and as a result, investors require more jump risk premium which generates a pronounced volatility smirk. Second, based on the general equilibrium framework, this book proposes variance risk premium and empirically tests its predictive power for international stock market returns.

Available in PDF, EPUB and Kindle. Book excerpt: Does the presence of arbitrageurs decrease equilibrium asset price volatility? I study an economy with arbitrageurs, informed investors, and noise traders. Arbitrageurs face a trade-off between arbitrage and inference: they would like to buy assets in response to temporary price declines (the arbitrage effect) but sell when prices decline permanently (the inference effect). In equilibrium, the presence of arbitrageurs increases volatility when the inference effect dominates the arbitrage effect. From a technical point of view, this paper offers closed-form solutions to a dynamic equilibrium model with asymmetric information and non-Gaussian priors.

Available in PDF, EPUB and Kindle. Book excerpt: This book rehabilitates beta as a definition of systemic risk by using particle physics to evaluate discrete components of financial risk. Much of the frustration with beta stems from the failure to disaggregate its discrete components; conventional beta is often treated as if it were "atomic" in the original Greek sense: uncut and indivisible. By analogy to the Standard Model of particle physics theory's three generations of matter and the three-way interaction of quarks, Chen divides beta as the fundamental unit of systemic financial risk into three matching pairs of "baryonic" components. The resulting econophysics of beta explains no fewer than three of the most significant anomalies and puzzles in mathematical finance. Moreover, the model's three-way analysis of systemic risk connects the mechanics of mathematical finance with phenomena usually attributed to behavioral influences on capital markets. Adding consideration of volatility and correlation, and of the distinct cash flow and discount rate components of systematic risk, harmonizes mathematical finance with labor markets, human capital, and macroeconomics.
