Download or read book The Role and Relevance of Option Implied Volatility in Financial Markets written by Megha Agarwal and published by . This book was released on 2014 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research paper is an effort to review the relevance of option implied volatility in the modern day financial markets. Volatility indices such as VIX, VFTSE and India VIX act as efficient predictors of market volatility over the near term. The role implied volatility plays in providing a measure of investors fears, explaining stock returns, credit default swap valuation, measuring bank risk, and understanding interest rate models for pricing contingent claims has been emphasized. The cases of Euro dollar option markets, S&P 100 index options, agricultural commodities on New York Board of Trade, sweet crude oil futures on NYMEX have been discussed in particular.This measure of investors fear gauge is found to be superior to logit regression and Altman's Z. It would have been helpful in predicting the UK Banking Crisis 2008. This important determinant of volatility must be incorporated in risk management strategies to lead to a robust and integrated risk management framework.

Available in PDF, EPUB and Kindle. Book excerpt: Praise for The Volatility Surface "I'm thrilled by the appearance of Jim Gatheral's new book The Volatility Surface. The literature on stochastic volatility is vast, but difficult to penetrate and use. Gatheral's book, by contrast, is accessible and practical. It successfully charts a middle ground between specific examples and general models--achieving remarkable clarity without giving up sophistication, depth, or breadth." --Robert V. Kohn, Professor of Mathematics and Chair, Mathematical Finance Committee, Courant Institute of Mathematical Sciences, New York University "Concise yet comprehensive, equally attentive to both theory and phenomena, this book provides an unsurpassed account of the peculiarities of the implied volatility surface, its consequences for pricing and hedging, and the theories that struggle to explain it." --Emanuel Derman, author of My Life as a Quant "Jim Gatheral is the wiliest practitioner in the business. This very fine book is an outgrowth of the lecture notes prepared for one of the most popular classes at NYU's esteemed Courant Institute. The topics covered are at the forefront of research in mathematical finance and the author's treatment of them is simply the best available in this form." --Peter Carr, PhD, head of Quantitative Financial Research, Bloomberg LP Director of the Masters Program in Mathematical Finance, New York University "Jim Gatheral is an acknowledged master of advanced modeling for derivatives. In The Volatility Surface he reveals the secrets of dealing with the most important but most elusive of financial quantities, volatility." --Paul Wilmott, author and mathematician "As a teacher in the field of mathematical finance, I welcome Jim Gatheral's book as a significant development. Written by a Wall Street practitioner with extensive market and teaching experience, The Volatility Surface gives students access to a level of knowledge on derivatives which was not previously available. I strongly recommend it." --Marco Avellaneda, Director, Division of Mathematical Finance Courant Institute, New York University "Jim Gatheral could not have written a better book." --Bruno Dupire, winner of the 2006 Wilmott Cutting Edge Research Award Quantitative Research, Bloomberg LP

Download or read book The Volatility Smile written by Emanuel Derman and published by John Wiley & Sons. This book was released on 2016-09-06 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Volatility Smile The Black-Scholes-Merton option model was the greatest innovation of 20th century finance, and remains the most widely applied theory in all of finance. Despite this success, the model is fundamentally at odds with the observed behavior of option markets: a graph of implied volatilities against strike will typically display a curve or skew, which practitioners refer to as the smile, and which the model cannot explain. Option valuation is not a solved problem, and the past forty years have witnessed an abundance of new models that try to reconcile theory with markets. The Volatility Smile presents a unified treatment of the Black-Scholes-Merton model and the more advanced models that have replaced it. It is also a book about the principles of financial valuation and how to apply them. Celebrated author and quant Emanuel Derman and Michael B. Miller explain not just the mathematics but the ideas behind the models. By examining the foundations, the implementation, and the pros and cons of various models, and by carefully exploring their derivations and their assumptions, readers will learn not only how to handle the volatility smile but how to evaluate and build their own financial models. Topics covered include: The principles of valuation Static and dynamic replication The Black-Scholes-Merton model Hedging strategies Transaction costs The behavior of the volatility smile Implied distributions Local volatility models Stochastic volatility models Jump-diffusion models The first half of the book, Chapters 1 through 13, can serve as a standalone textbook for a course on option valuation and the Black-Scholes-Merton model, presenting the principles of financial modeling, several derivations of the model, and a detailed discussion of how it is used in practice. The second half focuses on the behavior of the volatility smile, and, in conjunction with the first half, can be used for as the basis for a more advanced course.

Download or read book Option Market In efficiency and Implied Volatility Dynamics After Return Jumps written by Juho Kanniainen and published by . This book was released on 2019 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: In informationally efficient financial markets, option prices and this implied volatility should immediately be adjusted to new information that arrives along with a jump in underlying's return, whereas gradual changes in implied volatility would indicate market inefficiency. Using minute-by-minute data on S&P 500 index options, we provide evidence regarding delayed and gradual movements in implied volatility after the arrival of return jumps. These movements are directed and persistent, especially in the case of negative return jumps. Our results are significant when the implied volatilities are extracted from at-the-money options and out-of-the-money puts, while the implied volatility obtained from out-of-the-money calls converges to its new level immediately rather than gradually. Thus, our analysis reveals that the implied volatility smile is adjusted to jumps in underlying's return asymmetrically. Finally, it would be possible to have statistical arbitrage in zero-transaction-cost option markets, but under actual option price spreads, our results do not imply abnormal option returns.

Available in PDF, EPUB and Kindle. Book excerpt: Principles of Financial Engineering, Third Edition, is a highly acclaimed text on the fast-paced and complex subject of financial engineering. This updated edition describes the "engineering" elements of financial engineering instead of the mathematics underlying it. It shows how to use financial tools to accomplish a goal rather than describing the tools themselves. It lays emphasis on the engineering aspects of derivatives (how to create them) rather than their pricing (how they act) in relation to other instruments, the financial markets, and financial market practices. This volume explains ways to create financial tools and how the tools work together to achieve specific goals. Applications are illustrated using real-world examples. It presents three new chapters on financial engineering in topics ranging from commodity markets to financial engineering applications in hedge fund strategies, correlation swaps, structural models of default, capital structure arbitrage, contingent convertibles, and how to incorporate counterparty risk into derivatives pricing. Poised midway between intuition, actual events, and financial mathematics, this book can be used to solve problems in risk management, taxation, regulation, and above all, pricing. A solutions manual enhances the text by presenting additional cases and solutions to exercises. This latest edition of Principles of Financial Engineering is ideal for financial engineers, quantitative analysts in banks and investment houses, and other financial industry professionals. It is also highly recommended to graduate students in financial engineering and financial mathematics programs. The Third Edition presents three new chapters on financial engineering in commodity markets, financial engineering applications in hedge fund strategies, correlation swaps, structural models of default, capital structure arbitrage, contingent convertibles and how to incorporate counterparty risk into derivatives pricing, among other topics Additions, clarifications, and illustrations throughout the volume show these instruments at work instead of explaining how they should act The solutions manual enhances the text by presenting additional cases and solutions to exercises

Available in PDF, EPUB and Kindle. Book excerpt: Practical option strategies for the new post-crisis financial market Traditional buy-and-hold investing has been seriously challenged in the wake of the recent financial crisis. With economic and market uncertainty at a very high level, options are still the most effective tool available for managing volatility and downside risk, yet they remain widely underutilized by individuals and investment managers. In Options for Volatile Markets, Richard Lehman and Lawrence McMillan provide you with specific strategies to lower portfolio volatility, bulletproof your portfolio against any catastrophe, and tailor your investments to the precise level of risk you are comfortable with. While the core strategy of this new edition remains covered call writing, the authors expand into more comprehensive option strategies that offer deeper downside protection or even allow investors to capitalize on market or individual stock volatility. In addition, they discuss new offerings like weekly expirations and options on ETFs. For investors who are looking to capitalize on global investment opportunities but are fearful of lurking "black swans", this book shows how ETFs and options can be utilized to construct portfolios that are continuously protected against unforeseen calamities. A complete guide to the increased control and lowered risk covered call writing offers active investors and traders Addresses the changing investment environment and how to use options to succeed within it Explains how to use options with exchange-traded funds Understanding options is now more important than ever, and with Options for Volatile Markets as your guide, you'll quickly learn how to use them to protect your portfolio as well as improve its overall performance.

Download or read book An Empirical Examination of Informed Trading in the Option Market written by Thi Thanh Van Le and published by . This book was released on 2012 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite a growing research interest in option trading and its impact on the pricing of the underlying asset, the role of options as a vehicle for informed trading remains an important economic question which has not yet been fully explored. In fact, even though academics have often argued that informed traders may prefer to trade in the option market rather than the equity market1, the question of whether (and to what extent) such a proposition would hold in practice has not been systematically addressed in the literature. This overarching research problem forms the foundation of this doctoral research project, leading to two important research questions. First, if investors do in fact use options to trade on information about underlying stock prices in practice, what implications does this have for the option (stock) pricing and forecasting? Second, what are the key factors driving traders' decisions to trade on new information in one market over another? These two issues correspond to the two gaps found in the extant literature on option trading, and also in the strand of empirical studies focusing on the role of options as a mechanism for trading on information about the underlying asset. To explore these research questions, three interrelated projects have been undertaken, each with a unique contribution to informing the research topic. These closely related investigations jointly provide consolidated answers to the two research questions raised previously. In response to the first research question, we pursue two strands of empirical investigation to examine the presence of informed trading in the option market. Firstly, we investigate the extent to which the information content extracted from options trading can be used to enhance predictions of the future volatility realised by underlying stocks. Secondly, we examine the price impact of information trading activities within the option market, focusing especially on the way in which the level of trading activities can explain and predict the future dynamics of the option implied volatility smile. Both of these strands yield evidence in support of information trading activities existing in the option market. Regarding the second research question, our collective evidence indicates that the allocation of informed traders between option and stock markets depends on the trade-off of transaction costs and trading opportunities existing in two related markets. This finding has consistently been corroborated by separate evidence emerging from our independent investigations. We found that the degree of information trading in the option market varies across different stocks, corresponding to variations in the level of individual stock liquidity. It has also been found that the degree of information asymmetry of option trades changed in response to changes in trading costs driven by regulatory changes observed during the 2008 short-sale ban. This research makes a valuable contribution to the field of option research. From the theoretical perspective, it addresses significant gaps in the existing literature and extends our understanding of informed trading activities in the option market. In particular, it contributes to the body of knowledge on the economic value of derivatives by investigating the critical role they have played in the process of incorporating new information into the market. From the practical perspective, it proposes a simple-yet-effective technique which employs trading volume to improve forecasts of the underlying stock volatility and of the option implied volatility (price) respectively. Since volatility plays such a central role in the practice of derivatives trading, risk analysis and portfolio management, better forecasts of these quantities are clearly important and highly regarded by practitioners. 1 Mainly due to higher financial leverages, reduced transactions costs and wider trading opportunities (eg speculation on volatility) (Black, 1975).

Download or read book Implied Volatility Functions written by Bernard Dumas and published by . This book was released on 1996 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Black and Scholes (1973) implied volatilities tend to be systematically related to the option's exercise price and time to expiration. Derman and Kani (1994), Dupire (1994), and Rubinstein (1994) attribute this behavior to the fact that the Black-Scholes constant volatility assumption is violated in practice. These authors hypothesize that the volatility of the underlying asset's return is a deterministic function of the asset price and time and develop the deterministic volatility function (DVF) option valuation model, which has the potential of fitting the observed cross-section of option prices exactly. Using a sample of S & P 500 index options during the period June 1988 through December 1993, we evaluate the economic significance of the implied deterministic volatility function by examining the predictive and hedging performance of the DV option valuation model. We find that its performance is worse than that of an ad hoc Black-Scholes model with variable implied volatilities.

Available in PDF, EPUB and Kindle. Book excerpt: In Volatility Trading, Sinclair offers you a quantitative model for measuring volatility in order to gain an edge in your everyday option trading endeavors. With an accessible, straightforward approach. He guides traders through the basics of option pricing, volatility measurement, hedging, money management, and trade evaluation. In addition, Sinclair explains the often-overlooked psychological aspects of trading, revealing both how behavioral psychology can create market conditions traders can take advantage of-and how it can lead them astray. Psychological biases, he asserts, are probably the drivers behind most sources of edge available to a volatility trader. Your goal, Sinclair explains, must be clearly defined and easily expressed-if you cannot explain it in one sentence, you probably aren't completely clear about what it is. The same applies to your statistical edge. If you do not know exactly what your edge is, you shouldn't trade. He shows how, in addition to the numerical evaluation of a potential trade, you should be able to identify and evaluate the reason why implied volatility is priced where it is, that is, why an edge exists. This means it is also necessary to be on top of recent news stories, sector trends, and behavioral psychology. Finally, Sinclair underscores why trades need to be sized correctly, which means that each trade is evaluated according to its projected return and risk in the overall context of your goals. As the author concludes, while we also need to pay attention to seemingly mundane things like having good execution software, a comfortable office, and getting enough sleep, it is knowledge that is the ultimate source of edge. So, all else being equal, the trader with the greater knowledge will be the more successful. This book, and its companion CD-ROM, will provide that knowledge. The CD-ROM includes spreadsheets designed to help you forecast volatility and evaluate trades together with simulation engines.

Download or read book Analysing Intraday Implied Volatility for Pricing Currency Options written by Thi Le and published by Springer Nature. This book was released on 2021-04-13 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the impact of high-frequency data in forecasting market volatility and options price. New technologies have created opportunities to obtain better, faster, and more efficient datasets to explore financial market phenomena at the most acceptable data levels. It provides reliable intraday data supporting financial investment decisions across different assets classes and instruments consisting of commodities, derivatives, equities, fixed income and foreign exchange. This book emphasises four key areas, (1) estimating intraday implied volatility using ultra-high frequency (5-minutes frequency) currency options to capture traders' trading behaviour, (2) computing realised volatility based on 5-minute frequency currency price to obtain speculators' speculation attitude, (3) examining the ability of implied volatility to subsume market information through forecasting realised volatility and (4) evaluating the predictive power of implied volatility for pricing currency options. This is a must-read for academics and professionals who want to improve their skills and outcomes in trading options.

Download or read book The Information Content of Options written by Yonatan Navon and published by . This book was released on 2014 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is to examine the information content of stock options in financial markets. A key question in financial economics is how information diffuses across markets and how quickly it is reflected in security prices. This thesis aims at exploring this question by investigating the informational role that options play in financial markets. This is achieved by exploring the joint cross section of option and bond prices, the informational role of options in seasoned equity offerings (SEOs), and the information content of options trading prior to announcements of changes to the S&P 500 Index.The thesis comprises three essays, each exploring the information content of equity options trading from a different angle. The first essay examines the joint cross section of option implied volatility and corporate bond returns. Theoretical and empirical work in finance suggests that stocks and bonds of the same issuing firm should share common risk factors. Therefore, new information about a firm should affect both its stock and bond prices. However, if one market offers trading incentives over other markets, informed traders and traders with better ability to process information may choose to trade in that market over the others. As a result, markets that provide advantages to informed traders will incorporate information prior to other markets. The empirical analysis in this chapter reveals that options trading is strongly predictive of corporate bond returns. A strategy of buying (selling) the portfolio with the lowest (highest) changes in option implied volatility yields an average monthly excess bond return of 1.03%. This strategy is statistically highly significant and economically very meaningful and indicates that information is incorporated into option prices prior to bond prices. In contrast, I find no evidence that bond prices incorporate information prior to option or stock prices. Since bond investors are generally sophisticated institutional investors who process information efficiently and the predictive ability of options is persistent, I conclude that informed trading rather than superior information processing abilities is responsible for the predictive ability of options.The second essay explores the information content of option implied volatility around the announcements and issue dates of SEOs. The literature on SEOs indicates that announcements and issue dates contain important information about firms and therefore provide profitable opportunities for traders with private information. While prior research has focused on the information content of short sales around SEOs, this study focuses on the information content of options which can act as an alternative for short selling. The empirical analysis provides evidence of informed trading in the options market around SEO announcements. Around SEO issue dates, I find that higher demand for put options is significantly related to larger issue discounts which is consistent with the manipulative trading hypothesis. The results in this study indicate that regulators should consider extending the short-sale restrictions of Rule 105 to restrict trading in related securities.Finally, the third essay investigates the information content of options prior to the S&P 500 Index inclusion and exclusion announcements. These announcements are unique events since they are not announced by the firm and, as stated by S&P, they should convey no new information. In addition, the large abnormal returns observed following these announcements make them distinctive ground for testing the informational role of options. Consistent with the notion that informed traders operate in the options market, the empirical results in this essay indicate that there is a significant relationship between options trading preceding index inclusion announcements and abnormal returns following these announcements. In contrast, I find no evidence for a relationship between options trading and abnormal returns following exclusion announcements.
