Download or read book Some Economically Meaningful Option Model Calibration Performance Measures written by Craig A. Friedman and published by . This book was released on 2014 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desire to more accurately calibrate option pricing models to liquid option prices has been an important driver of the growth of the option pricing literature and practice. However, the most commonly used model calibration accuracy metrics are not designed to reflect the economic consequences of trading based on model prices. To address this shortcoming, we derive, from first principles, in an idealized market setting, new, tractable, and economically meaningful, utility-based, measures of option pricing model calibration performance. We show that when pricing errors are “small,” our measures closely approximate popular percentage pricing error-based metrics. However, our measures can be quite different when model prices are smaller than they ought to be (which can happen when the option pricing model does not properly take into account fat-tailed asset return effects). We compare our measures with widely used metrics and show, via examples using SPX options data, that our new measures better inform us about the economic consequences of model pricing error and thereby better allow us to select among candidate option pricing models.

Available in PDF, EPUB and Kindle. Book excerpt: In spite of the popularity of model calibration in finance, empirical researchers have put more emphasis on model estimation than on the equally important goodness-of-fit problem. This is due partly to the ignorance of modelers, and more to the ability of existing statistical tests to detect specification errors. In practice, models are often calibrated by minimizing the sum of squared difference between the modelled and actual observations. It is challenging to disentangle model error from estimation error in the residual series. To circumvent the difficulty, we study an alternative way of estimating the model by exact calibration. We argue that standard time series tests based on the exact approach can better reveal model misspecifications than the error minimizing approach. In the context of option pricing, we illustrate the usefulness of exact calibration in detecting model misspecification. Under heteroskedastic observation error structure, our simulation results shows that the Black-Scholes model calibrated by exact approach delivers more accurate hedging performance than that calibrated by error minimization.
Download or read book Explanatory Model Analysis written by Przemyslaw Biecek and published by CRC Press. This book was released on 2021-02-15 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explanatory Model Analysis Explore, Explain and Examine Predictive Models is a set of methods and tools designed to build better predictive models and to monitor their behaviour in a changing environment. Today, the true bottleneck in predictive modelling is neither the lack of data, nor the lack of computational power, nor inadequate algorithms, nor the lack of flexible models. It is the lack of tools for model exploration (extraction of relationships learned by the model), model explanation (understanding the key factors influencing model decisions) and model examination (identification of model weaknesses and evaluation of model's performance). This book presents a collection of model agnostic methods that may be used for any black-box model together with real-world applications to classification and regression problems.
Download or read book Local Vs Global Calibration A Comparison of Option Hedging Strategies and Option Pricing Models written by Stefanie Hasse and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the empirical relationship of model fit, calibration methods and hedging performance for individual equity options. The sample used comprises of about 76,000 option prices for individual equity options recorded between January 2, 2008 and December 31, 2009. This sample has been used to first calibrate the stochastic volatility model by Heston (1993) by using two different calibration techniques, local and global calibration, and then to investigate hedging performance of the Heston model versus three simple adjustments to the model by Black and Scholes (1973) (BSM). It is found that the sticky-strike adjustment to the BSM outperforms the Heston model for delta and delta-gamma hedging of individual equity options, and the Heston model using parameters from local calibration performs best for delta-vega hedges. The results apply to both daily and weekly rebalancing of the hedging portfolios and are robust with respect to different moneyness categories and market regimes.

Available in PDF, EPUB and Kindle. Book excerpt: Cellular automata have become a core subject in the sciences of complexity due to their conceptual simplicity, easiness of implementation for computer simulation, and ability to exhibit a wide variety of amazingly complex behavior. These features of cellular automata have attracted the researchers attention from a wide range of divergent fields of science. In this book, six outstanding emerging cellular automata applications have been compiled. These contributions underline the versatility of cellular automata as models for a wide diversity of complex systems. We hope that, after reading the outstanding contributions compiled in this book, we will have succeeded in bringing across what engineers and scientists are now doing about the application of cellular automata for solving practical problems in diverse disciplines. We also hope that this book will have been to your interest and liking. Lastly, we would like to thank all the authors for their excellent contributions in the different topics of cellular automata covered in this book.

This book was released on 2017-04-24 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers both the practical and theoretical aspects of catastrophe modelling for insurance industry practitioners and public policymakers. Written by authors with both academic and industry experience it also functions as an excellent graduate-level text and overview of the field. Ours is a time of unprecedented levels of risk from both natural and anthropogenic sources. Fortunately, it is also an era of relatively inexpensive technologies for use in assessing those risks. The demand from both commercial and public interests—including (re)insurers, NGOs, global disaster management agencies, and local authorities—for sophisticated catastrophe risk assessment tools has never been greater, and contemporary catastrophe modelling satisfies that demand. Combining the latest research with detailed coverage of state-of-the-art catastrophe modelling techniques and technologies, this book delivers the knowledge needed to use, interpret, and build catastrophe models, and provides greater insight into catastrophe modelling’s enormous potential and possible limitations. The first book containing the detailed, practical knowledge needed to support practitioners as effective catastrophe risk modellers and managers Includes hazard, vulnerability and financial material to provide the only independent, comprehensive overview of the subject, accessible to students and practitioners alike Demonstrates the relevance of catastrophe models within a practical, decision-making framework and illustrates their many applications Includes contributions from many of the top names in the field, globally, from industry, academia, and government Natural Catastrophe Risk Management and Modelling: A Practitioner’s Guide is an important working resource for catastrophe modelling analysts and developers, actuaries, underwriters, and those working in compliance or regulatory functions related to catastrophe risk. It is also valuable for scientists and engineers seeking to gain greater insight into catastrophe risk management and its applications.
