This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We show that, for three common SARV models, fitting a minimum mean square linear filter is equivalent to fitting a GARCH model. This suggests that GARCH models may be useful for filtering, forecasting, and parameter estimation in stochastic volatility settings. To investigate, we use simulations to evaluate how the three SARV models and their associated GARCH filters perform under controlled conditions and then we use daily currency and equity index returns to evaluate how the models perform in a risk management application. Although the GARCH models produce less precise forecasts than the SARV models in the simulations, it is not clear that the performance differences are large enough to be economically meaningful. Consistent with this view, we find that the GARCH and SARV models perform comparably in tests of conditional value-at-risk estimates using the actual data.

Available in PDF, EPUB and Kindle. Book excerpt: A new, more accurate take on the classical approach to volatility evaluation Inside Volatility Filtering presents a new approach to volatility estimation, using financial econometrics based on a more accurate estimation of the hidden state. Based on the idea of "filtering", this book lays out a two-step framework involving a Chapman-Kolmogorov prior distribution followed by Bayesian posterior distribution to develop a robust estimation based on all available information. This new second edition includes guidance toward basing estimations on historic option prices instead of stocks, as well as Wiener Chaos Expansions and other spectral approaches. The author's statistical trading strategy has been expanded with more in-depth discussion, and the companion website offers new topical insight, additional models, and extra charts that delve into the profitability of applied model calibration. You'll find a more precise approach to the classical time series and financial econometrics evaluation, with expert advice on turning data into profit. Financial markets do not always behave according to a normal bell curve. Skewness creates uncertainty and surprises, and tarnishes trading performance, but it's not going away. This book shows traders how to work with skewness: how to predict it, estimate its impact, and determine whether the data is presenting a warning to stay away or an opportunity for profit. Base volatility estimations on more accurate data Integrate past observation with Bayesian probability Exploit posterior distribution of the hidden state for optimal estimation Boost trade profitability by utilizing "skewness" opportunities Wall Street is constantly searching for volatility assessment methods that will make their models more accurate, but precise handling of skewness is the key to true accuracy. Inside Volatility Filtering shows you a better way to approach non-normal distributions for more accurate volatility estimation.

Download or read book Hed ing deviznog rizika razvoj i primena finansijskih i operativnih strategija written by Milan Čupić and published by University of Kragujevac, Faculty of Economics. This book was released on 2024-09-12 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gotovo neprekidne finansijske neizvesnosti i krize izazvane finansijskim i nefinansijskim faktorima nas podsećaju na neophodnost i značaj literature u vezi sa hedžingom rizika. Nepredvidivost budućih promena deviznih kurseva je jedan od najvažnijih izvora neizvesnosti za preduzeća, bez obzira na to da li posluju u granicama jedne nacionalne privrede ili na globalnom nivou. Devizni rizik, kao izraz te neizvesnosti, može usloviti veoma nepovoljne promene domaće vrednosti nekih pozicija preduzeća ili pokazatelja poslovanja, pa privlači pažnju teorije i prakse. Budući da promene deviznih kurseva mogu značajno odrediti konkurentnost, novčane tokove i strategijsku orijentaciju preduzeća, izloženost deviznom riziku je strategijski problem koji zahteva strategijski odgovor. S tim u vezi, preduzeća koriste finansijske i operativne strategije. Finansijske strategije podrazumevaju zauzimanje pozicije u valutnom derivatu, sa ciljem smanjenja izloženosti u vezi sa osnovnom pozicijom u stranoj valuti, dok se operativne strategije zasnivaju na razvoju realnih opcija u domenu snabdevanja, proizvodnje i prodaje, sa ciljem optimiziranja izloženosti preduzeća u vezi sa očekivanim novčanim tokovima. Budući da se teorija i praksa finansija brzo menjaju i unapređuju, ova monografija je pisana u nastojanju da ukaže na strategijske odgovore koje preduzeća mogu da koriste kako bi kontrolisala uticaj deviznog rizika na svoje poslovanje. Imajući u vidu strategijsku dimenziju ovog problema, najviše pažnje je posvećeno analizi i objašnjenju modela za procenu izloženosti i strategijama za hedžing deviznog rizika. Posebno su istaknuti i analizirani pristupi dostupni preduzećima u Srbiji. Monografija „Hedžing deviznog rizika: razvoj i primena finansijskih i operativnih strategija“ je namenjena stručnjacima koji se u svakodnevnom radu sreću sa deviznim rizikom, studentima ekonomskih fakulteta, ali i svima koji žele da bolje razumeju uticaj deviznog rizika i praktične pristupe hedžingu. U očekivanju da će ova monografija doprineti boljem razumevanju složene problematike hedžinga deviznog rizika, autor je otvoren za konstruktivne sugestije naučne i stručne javnosti.

Download or read book Volatility and Correlation written by Riccardo Rebonato and published by John Wiley & Sons. This book was released on 2005-07-08 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Volatility and Correlation 2nd edition: The Perfect Hedger and the Fox, Rebonato looks at derivatives pricing from the angle of volatility and correlation. With both practical and theoretical applications, this is a thorough update of the highly successful Volatility & Correlation – with over 80% new or fully reworked material and is a must have both for practitioners and for students. The new and updated material includes a critical examination of the ‘perfect-replication’ approach to derivatives pricing, with special attention given to exotic options; a thorough analysis of the role of quadratic variation in derivatives pricing and hedging; a discussion of the informational efficiency of markets in commonly-used calibration and hedging practices. Treatment of new models including Variance Gamma, displaced diffusion, stochastic volatility for interest-rate smiles and equity/FX options. The book is split into four parts. Part I deals with a Black world without smiles, sets out the author’s ‘philosophical’ approach and covers deterministic volatility. Part II looks at smiles in equity and FX worlds. It begins with a review of relevant empirical information about smiles, and provides coverage of local-stochastic-volatility, general-stochastic-volatility, jump-diffusion and Variance-Gamma processes. Part II concludes with an important chapter that discusses if and to what extent one can dispense with an explicit specification of a model, and can directly prescribe the dynamics of the smile surface. Part III focusses on interest rates when the volatility is deterministic. Part IV extends this setting in order to account for smiles in a financially motivated and computationally tractable manner. In this final part the author deals with CEV processes, with diffusive stochastic volatility and with Markov-chain processes. Praise for the First Edition: “In this book, Dr Rebonato brings his penetrating eye to bear on option pricing and hedging.... The book is a must-read for those who already know the basics of options and are looking for an edge in applying the more sophisticated approaches that have recently been developed.” —Professor Ian Cooper, London Business School “Volatility and correlation are at the very core of all option pricing and hedging. In this book, Riccardo Rebonato presents the subject in his characteristically elegant and simple fashion...A rare combination of intellectual insight and practical common sense.” —Anthony Neuberger, London Business School
