Available in PDF, EPUB and Kindle. Book excerpt: During the 2007-2008 financial crisis, idiosyncratic and market volatilities across the world increased to level never seen before. The financial econometrics literature focused on the spectacular increase in aggregate idiosyncratic volatility. Bekaert, Hodrick, and Zhang (2012) showed the high correlation across countries, documenting how most of the time variation in idiosyncratic volatility can be attributed, among others, to variation in U.S. market volatility and a business cycle sensitive risk indicator. However, what worried most asset managers and commentators was not so much the increase in volatility per se but the dramatic increase in correlation between and within stock markets. A phenomenon interpreted by the financial press as a sort of structural break in stock market dynamics. Sandoval and De Paula (2011) studied the phenomenon of the increase in correlation during period of crisis. They found that markets tend to behave as one in time of crisis. I will show that it is possible to calibrate a simple dynamic CAPM model over the last 20 years that fits very well the observed dynamic of stock markets' volatility and correlation. I use the model to investigate if the 2007-8 environment should have been detrimental to bottom-up managers and favourable for top-down manager, as far as “alpha” creation is concerned. There is in fact a sort of consensus view about the fact that the increase in correlation observed during the 2007-2008 should have impaired the capabilities of bottom-up managers to produce alpha. As there is good and bad cholesterol, there is good and bad volatility for bottom-up alpha generators.

Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates volatility contagion across U.S. and European stock markets during the Global Financial Crisis (GFC) and the Eurozone Sovereign Debt Crisis (ESDC). Using a sample of international implied volatility indices on daily changes, I explore asymmetric conditional correlation dynamics across stable and crisis periods and across the different phases of both crises. Empirical evidence indicates the existence of contagion in cross-market volatilities. A different pattern of infection is observed across the phases, since the early phase of the GFC and the late period of escalation of the Euro crisis are the most contagious periods. This implies that the initial signal of the two crises has been differently recognized by implied volatility markets. The results provide important implications for the effectiveness of international portfolio diversification and volatility hedging during periods of negative shocks.

Available in PDF, EPUB and Kindle. Book excerpt: We investigate dynamics between the economic activities and energy markets - both conventional and clean energy markets, with a sample of daily data from January 01, 2020, to November 25, 2020. We perform wavelet-based time-frequency techniques; we measure the market volatility with continuous wavelet transforms (CWT), co-movement of economic activities, and energy markets using wavelet coherency as well as non-linear phase-difference technique to understand the time-varying causality between different series. Our CWT results show that all three market indices experience significant volatility in the COVID-19 period, notably during the initial period of the outbreak. The market volatilities are comparatively more substantial in the short frequency band than the long frequency, while the latter sustained longer in the markets. Moreover, wavelet coherency results show a strong correlation between the economic activity index and both energy market indices; however, the co-movement is significantly higher for the conventional energy market than the clean energy market. We further detect a positive and bi-directional causality between economic activities and energy market indices. Besides providing fresh and time-varying and frequency-varying variance, correlation and causal relationship between global economic activity and the energy markets, which is currently lacking in the existing literature, our study has significant implications for the heterogeneous market participants in terms of improved price prediction accuracy and policymakers for decision-making during the crisis period.

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

This book was released on 2016 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous research indicates that performance and volatility of small and regional stock markets can be influenced by the performance of major world exchanges such as New York, Frankfurt or Tokyo stock exchange. This research analyses weekly composite index data for SASE (Sarajevo Stock Exchange), NYSE, NIKKEI, and DAX indices, for the period from 2008 until the end of 2012. This time period contains significant events in the US and the rest of the world, including the housing bubble, and a great recession which followed after. Significant volatility of SASE was noted in 2007 while later periods suggest lesser volatility after a significant drop in index value in mid 2007. The data was analyzed in a side by side comparison, by the method of regression in order to establish a correlation of NYSE, NIKKEI and DAX indexes with Sarajevo Stock Exchange index. Furthermore the performance was visually represented, segmented into several dynamic and steady periods, whose regressions were separately calculated, in order to see the difference in steady and dynamic periods. Previous research suggests strong correlation between regional and major stock market indices at times of crisis, a so called spillover effect, while low correlation at times of low volatility. With these results, we will be able to understand the impact of major world indices on volatility and performance movements of Sarajevo Stock Exchange in the long and short run, as well as at times of low and high volatility. The results of research suggest that when there is less dynamics in major world indices, the SASE market becomes less affected by their results and by the global market trends, thus its performance is then dictated to a higher degree by regional or country specific financial, economic and to some degree political factors. On the other hand we can also deduce that when there are significant events developing in these major world indices, SASE's composite index performance are highly correlated to the dynamics and trends of major world indices. One such case this paper analyzed is evident in the 'dynamic period' of some 18 months, ranging from 01.01.2009-16.06.2010, where the impact of global recession on major world indexes spilled over to smaller regional exchanges; correlation between SASE and NYSE in that period is 0,92.

It has also raised the question whether financial connectedness - a possible source of systemic risk - can serve as an early warning indicator of crises. In this paper we examine the ability of connectedness in the global network of financial linkages to predict systemic banking crises. Our results indicate that increases in a country's financial interconnectedness and decreases in its neighbors' connectedness are associated with a higher probability of banking crises after controlling for macroeconomic fundamentals.

Book excerpt: We provide a comprehensive empirical characterization of the linkages between key macroeconomic and financial variables around business and financial cycles for 21 OECD countries over the period 1960–2007. In particular, we analyze the implications of 122 recessions, 112 (28) credit contraction (crunch) episodes, 114 (28) episodes of house price declines (busts), 234 (58) episodes of equity price declines (busts) and their various overlaps in these countries over the sample period. Our results indicate that interactions between macroeconomic and financial variables can play major roles in determining the severity and duration of recessions. Specifically, we find evidence that recessions associated with credit crunches and house price busts tend to be deeper and longer than other recessions.

This book was released on 2020-07-30 with total page 5053 pages. Available in PDF, EPUB and Kindle. Book excerpt: This four-volume handbook covers important concepts and tools used in the fields of financial econometrics, mathematics, statistics, and machine learning. Econometric methods have been applied in asset pricing, corporate finance, international finance, options and futures, risk management, and in stress testing for financial institutions. This handbook discusses a variety of econometric methods, including single equation multiple regression, simultaneous equation regression, and panel data analysis, among others. It also covers statistical distributions, such as the binomial and log normal distributions, in light of their applications to portfolio theory and asset management in addition to their use in research regarding options and futures contracts.In both theory and methodology, we need to rely upon mathematics, which includes linear algebra, geometry, differential equations, Stochastic differential equation (Ito calculus), optimization, constrained optimization, and others. These forms of mathematics have been used to derive capital market line, security market line (capital asset pricing model), option pricing model, portfolio analysis, and others.In recent times, an increased importance has been given to computer technology in financial research. Different computer languages and programming techniques are important tools for empirical research in finance. Hence, simulation, machine learning, big data, and financial payments are explored in this handbook.Led by Distinguished Professor Cheng Few Lee from Rutgers University, this multi-volume work integrates theoretical, methodological, and practical issues based on his years of academic and industry experience.

Available in PDF, EPUB and Kindle. Book excerpt: Financial markets respond to information virtually instantaneously. Each new piece of information influences the prices of assets and their correlations with each other, and as the system rapidly changes, so too do correlation forecasts. This fast-evolving environment presents econometricians with the challenge of forecasting dynamic correlations, which are essential inputs to risk measurement, portfolio allocation, derivative pricing, and many other critical financial activities. In Anticipating Correlations, Nobel Prize-winning economist Robert Engle introduces an important new method for estimating correlations for large systems of assets: Dynamic Conditional Correlation (DCC). Engle demonstrates the role of correlations in financial decision making, and addresses the economic underpinnings and theoretical properties of correlations and their relation to other measures of dependence. He compares DCC with other correlation estimators such as historical correlation, exponential smoothing, and multivariate GARCH, and he presents a range of important applications of DCC. Engle presents the asymmetric model and illustrates it using a multicountry equity and bond return model. He introduces the new FACTOR DCC model that blends factor models with the DCC to produce a model with the best features of both, and illustrates it using an array of U.S. large-cap equities. Engle shows how overinvestment in collateralized debt obligations, or CDOs, lies at the heart of the subprime mortgage crisis--and how the correlation models in this book could have foreseen the risks. A technical chapter of econometric results also is included. Based on the Econometric and Tinbergen Institutes Lectures, Anticipating Correlations puts powerful new forecasting tools into the hands of researchers, financial analysts, risk managers, derivative quants, and graduate students.
