Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have underscored the need for market participants to develop reliable methods of measuring risk. One increasingly popular technique is the use of "value-at-risk" models, which convey estimates of market risk for an entire portfolio in one number. The author explores how well these models actually perform by applying twelve value-at-risk approaches to 1,000 randomly chosen foreign exchange portfolios. Using nine criteria to evaluate model performance, he finds that the approaches generally capture the risk that they set out to assess and tend to produce risk estimates that are similar in average size. No approach, however, appears to be superior by every measure.

Available in PDF, EPUB and Kindle. Book excerpt: "This book, Measuring Market Risk with Value at Risk by Vipul Bansal and Pietro Penza, has three advantages over earlier works on the subject. First, it takes a decidedly global approach-an essential ingredient for any comprehensive work on market risk. Second, it ties the scientifically grounded, yet intuitively appealing, VaR measure to earlier, more idiosyncratic measures of market risk that are used in specific market environs (e.g., duration in fixed income). Finally, it encompasses all of the accepted approaches to calculating a VaR measure and presents them in a clearly explained fashion with supporting illustrations and completely worked-out examples." -from the Foreword by John F. Marshall, PhD, Principal, Marshall, Tucker & Associates, LLC "Measuring Market Risk with Value at Risk offers a much-needed intellectual bridge, a translation from the esoteric realm of mathematical finance to the domain of financial managers who seek guidance in applying developments from this important field of research as well as that of MBA-level graduate instruction. I believe the authors have done a commendable job of providing a carefully crafted, highly readable, and most useful work, and intend to recommend it to all those involved in business risk management applications." -Anthony F. Herbst, PhD, Professor of Finance and C.R. and D.S. Carter Chair, The University of Texas, El Paso and Founding editor of The Journal of Financial Engineering (1991-1998) "Finally there's a book that strikes a balance between rigor and application in the area of risk management in the banking industry. This innovative book is a MUST for both novices and professionals alike." -Robert P. Yuyuenyongwatana, PhD, Associate Professor of Finance, Cameron University "Measuring Market Risk with Value at Risk is one of the most complete discussions of this emerging topic in finance that I have seen. The authors develop a logical and rigorous framework for using VaR models, providing both historical references and analytical applications." -Kevin Wynne, PhD, Associate Professor of Finance, Lubin School of Business, Pace University

Download or read book Market Risk Analysis Value at Risk Models written by Carol Alexander and published by John Wiley & Sons. This book was released on 2009-02-09 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by leading market risk academic, Professor Carol Alexander, Value-at-Risk Models forms part four of the Market Risk Analysis four volume set. Building on the three previous volumes this book provides by far the most comprehensive, rigorous and detailed treatment of market VaR models. It rests on the basic knowledge of financial mathematics and statistics gained from Volume I, of factor models, principal component analysis, statistical models of volatility and correlation and copulas from Volume II and, from Volume III, knowledge of pricing and hedging financial instruments and of mapping portfolios of similar instruments to risk factors. A unifying characteristic of the series is the pedagogical approach to practical examples that are relevant to market risk analysis in practice. All together, the Market Risk Analysis four volume set illustrates virtually every concept or formula with a practical, numerical example or a longer, empirical case study. Across all four volumes there are approximately 300 numerical and empirical examples, 400 graphs and figures and 30 case studies many of which are contained in interactive Excel spreadsheets available from the the accompanying CD-ROM . Empirical examples and case studies specific to this volume include: Parametric linear value at risk (VaR)models: normal, Student t and normal mixture and their expected tail loss (ETL); New formulae for VaR based on autocorrelated returns; Historical simulation VaR models: how to scale historical VaR and volatility adjusted historical VaR; Monte Carlo simulation VaR models based on multivariate normal and Student t distributions, and based on copulas; Examples and case studies of numerous applications to interest rate sensitive, equity, commodity and international portfolios; Decomposition of systematic VaR of large portfolios into standard alone and marginal VaR components; Backtesting and the assessment of risk model risk; Hypothetical factor push and historical stress tests, and stress testing based on VaR and ETL.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives an overview of evaluation of the most widespread Value at Risk (VaR)Models in use in most of risk management departments across the financial industry.Value at Risk (VaR) has become the standard measure that financial analysts use to quantify market risk. VaR is defined as the maximum potential change in value of a portfolio of financial instruments with a given probability over a certain horizon. VaR measures can have many applications, such as in risk management, to evaluate the performance of risk takers and for regulatory requirements, and hence it is very important to develop methodologies that provide accurate estimates.The main objective of this book is to survey the most popular univariate VaR methodologies, paying particular attention to their underlying assumptions. The great popularity that this instrument has achieved is essentially due to its conceptual simplicity: VaR reduces the (market) risk associated with any portfolio to just one number, the loss associated to a given probability. VaR can also be applied to governance of endowments, trusts, and pension plans. Essentially trustees adopt portfolio VaR metrics for the entire pooled account.

Download or read book Analysis of Value at Risk Models Based on the Shanghai Stock Index written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, Value at Risk has been universally accepted as a measure of market risk in financial institutions. A lot of research has been done in the field of Value at Risk leading to the development of differing approaches to estimate Value at Risk. However each method has its own set of assumptions and there is very little consensus on the preferred method to estimate Value at Risk. Since all existing methods involve some tradeoff and simplifications, determining the best methodology for estimating Value at Risk becomes an empirical question for implementing the most suitable model. The challenge of this work is to come up with the best and easily implementable approach suitable to Shanghai Stock index data and apply time series models for calculating Value at Risk and compare their performance with current models. Several sketches of current methods are introduced with open issues associated with each method. The study identifies the path for future research to improve the performance of models. The Value at Risk models are evaluated over the two sample periods. The two periods serve to validate the performance of models over time. The best models (EWMA and GARCH) models were reevaluated for the extended forecast sample period and it was found that GARCH models performed consistently over the time. The study makes use of both parametric and non parametric models and also proposes some of the models to estimate Value at Risk. Performance evaluation of the risk metrics, Garch models and historical simulation Value at Risk models are outlined and assumptions tested on Shanghai stock exchange index. The risk metrics and the Garch models incorporate volatility updating as well as clustering phenomenon. It does a poor job in capturing the extreme tail region as compared to historical simulation models. On the other hand historical simulation models capture the tail of the empirical distribution, but are practically insensitive to periods of sudden volatility. Time series models fail to reject the random walk hypothesis and perform poorly in comparison to the current model .Overall the risk metrics model with decay factor of 0.90 performs better than all other models when comparing the accuracy of Value at Risk estimates in first sample period. However over the both forecast sample periods the GARCH models perform consistently. The performance of EWMA marginally deteriorates for the second sample period. It is felt that the conditioning on the past movement of the stock or assert in the previous period will significantly improve the performance of current Value at Risk models. The movements on the positive side should produce less volatility than the movements of equal magnitude on the negative side. This can be taken care of by conditioning of variance of returns on the direction of movement of asset.

This book was released on 2006-05-21 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2004 in the subject Business economics - Controlling, grade: 1,7, European Business School - International University Schloß Reichartshausen Oestrich-Winkel (Department of Accounting and Control), language: English, abstract: The risk and return framework is generally accepted and discussed by scientists, at least since Markowitz introduced his Portfolio Theory in 1952. Subsequently, models were developed to evaluate investments under consideration of risk and return. Traditionally, practitioners primarily focused on past earnings as a measure of the profitability of an investment, without adequately considering potential risks. Therefore, the development of professional risk management systems was often neglected. Thus, the possibility of high losses was not appropriately incorporated in their investment strategies. The consequences of such mistreatment became evident in the mid 1990s, when some of the world’s largest companies faced huge losses and sometimes even insolvency. Most of these failures were a direct result of inappropriate use of financial instruments and insufficient internal control mechanisms. The most spectacular debacles even resulted in losses of more than one billion dollars for each affected institution. In case of Barings Bank, a single trader ruined the 233-year old British financial institution by inappropriate investments in high-risk futures in 1995. The consequent loss of $1.3 billion, realized in a very short period, could not be absorbed and forced the downfall of Barings. At Daiwa Bank, it was also a single trader who caused a $1.1 billion deficit. In contrast, the losses were accumulated over 11 years from 1984. Another well-publicized bankruptcy was declared in 1994 by the Californian Orange County, after losses of $1.8 billion. Such evidence of poor risk management and control shows that proper financial risk management is crucial for all kinds of institutions in order to guarantee stability and continuity. Therefore, it is necessary to establish adequate risk management processes and to develop appropriate tools, which quantify risk exposures of both entire institutions and single financial instruments. This risk quantification should alert management early enough to prevent exceptional losses. One of the key concepts addressing these prob-lems of modern risk management was introduced in 1993 with the Value-at-Risk (VaR) models.

Available in PDF, EPUB and Kindle. Book excerpt: Implementing Value at Risk Philip Best Value at Risk (VAR) is an estimate of the potential loss on a trading or investment portfolio. Its use has swept the banking world and is now accepted as an essential tool in any risk manager's briefcase. Perhaps the greatest strength of VAR is that it can cope with virtually all financial products, from simple securities through to complex exotic derivatives. This allows the risk taken, across diverse trading activities, to be compared. This said, VAR is no panacea. It is as critical to understand when the use of VAR is inappropriate as it is to understand the value VAR can add to a bank's understanding and control of its risks. This book aims to explain how VAR can be used as an integral part of a risk and business management framework, rather than as a stand-alone tool. The objectives of this book are to explain: What VAR is - and isn't! How to calculate VAR - the three main methods Why stress testing is needed to complement VAR How to make stress testing effective How to use VAR and stress testing to manage risk How to use VAR to improve a bank's performance VAR as a regulatory measure of risk and capital Risk management practitioners, general bank managers, consultants and students of finance and risk management will find this book, and the software package included, an invaluable addition to their library.

Download or read book Risk in International Finance written by Vikash Yadav and published by Routledge. This book was released on 2008-03-19 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the evolution and impact of the concept of risk on processes of transnational banking and financial market regulation, as well as the externalities generated by speculative financial activity in developing and emerging market economies. The author provides an alternative theory for the study of international financial market regulation by applying elements of a post-structural methodology to the topic. Inspired by Michel Foucault’s framework of critical discourse analysis in The History of Sexuality, the argument dissects the rules of formation that govern the evolving discourse on risk. The author argues that the mathematically formal technology of risk emerges from within specific institutions and economic formations; thereby limiting its utility in the regulation of global financial markets. Exploring how the applied technology of risk has been implicated for fueling a major financial crisis, his work also demonstrates how the regulation of global financial markets and abstruse financial instruments in advanced industrialized countries impacts the lives of the poorest people in developing countries and emerging markets.
