Available in PDF, EPUB and Kindle. Book excerpt: Testing the hypothesis that international equity market correlation increases in volatile times is a difficult exercise and misleading results have often been reported in the past because of a spurious relationship between correlation and volatility. This paper focuses on extreme correlation, that is to say the correlation between returns in either the negative or positive tail of the multivariate distribution. Using ldquo;extreme value theoryrdquo; to model the multivariate distribution tails, we derive the distribution of extreme correlation for a wide class of return distributions. Using monthly data on the five largest stock markets from 1958 to 1996, we reject the null hypothesis of multivariate normality for the negative tail, but not for the positive tail. We also find that correlation is not related to market volatility per se but to the market trend. Correlation increases in bear markets, but not in bull markets.

Available in PDF, EPUB and Kindle. Book excerpt: This study uses bivariate extremal dependence measures, based on the number of equity return co-exceedances in two markets, to quantify both negative and positive equity returns contagion in mature and emerging equity markets during the past decade. The results indicate (a) higher contagion for negative returns than for positive returns; (b) a secular increase in contagion in Latin America not matched in other regions; (c) global increases in contagion following the 1998 financial crises; and (d) that the use of simple correlations as a proxy for contagion could be misleading, as the former exhibit low correlation with extremal dependence measures of contagion.

Available in PDF, EPUB and Kindle. Book excerpt: Benefits to portfolio diversification depend crucially on correct correlation estimates, hence it is of great importance to both risk management and portfolio optimisation that the exact nature of the correlation structure between international financial assets is understood. Recent discussion on the correlation of international equity returns has focussed on the issue of whether extreme movements in international financial markets are more highly correlated than usual returns. This implies a reduction in the benefits from portfolio diversification since extreme returns are more likely to occur with greater simultaneity. Using the Value-at-Risk methodology we are able to measure the quantile correlation structure implicit in international asset returns in a simple manner without having to resort to fully parametric modelling. We illustrate that the extraction of the quantile covariance structure from this quantile correlation structure is non-trivial. Using daily data on stock market indices for a variety of countries we observe how the correlation and covariance structure changes as we move into the tails of the return distribution. We find for extreme stock market movements the benefits to international diversification are significantly curtailed even after discarding spurious correlation changes.

Available in PDF, EPUB and Kindle. Book excerpt: Extreme Value Theory (EVT) offers a powerful framework to characterize financial market crashes and booms. This paper applies EVT to model the behavior of extreme events and compares tail thickness between emerging and developed market equity return distributions. We extend previous results by augmenting parametric Monte Carlo tests with nonparametric bootstrap tests. We construct Monte Carlo and Bootstrapping experiments to estimate the statistical significance of differences in tail behavior between markets and regions. Within each market we find little evidence for asymmetry between positive and negative tails. We find mixed evidence for uniformity inside each region, and strong evidence for differences in tail behavior between emerging and developed regions. Our regional results have important implications for the expected diversification benefits of international portfolio allocation decisions.

Download or read book Modelling Extreme Financial Returns of Global Equity Markets written by John Cotter and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme asset price movements appear to be more pronounced recently and have major consequences for an economy's financial stability and monetary policies. This paper investigates the extreme behaviour of equity market returns and quantifies the probabilities of these losses. Taking fourteen major equity markets the study is able to ascertain similarities and divergences in the tail returns from around the world. To do so, it applies extreme value theory to equity indices representing American, Asian and European markets. The paper finds that all markets tail realisations are adequately modelled with the fat-tailed Frechet distribution. Furthermore tail realisations associated with the downside of a distribution are greater than those associated with the upside, and extreme returns for Asian markets are usually larger than their European and American counterparts.

Download or read book The Internationalization of Equity Markets written by Jeffrey A. Frankel and published by University of Chicago Press. This book was released on 2008-04-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely volume addresses three important recent trends in the internationalization of United States equity markets: extensive market integration through foreign investment and links among stock prices around the world; increasing securitization as countries such as Japan come to rely more than ever before on markets in equities and bonds at the expense of banks; and the opening of national financial systems of newly industrializing countries to international financial flows and institutions, as governments remove capital controls and other barriers. Eight essays examine such issues as the current extent of international market integration, gains to U.S. investors through international diversification, home-country bias in investing, the role of time and location around the world in stock trading, and the behavior of country funds. Other, long-standing questions about equity markets are also addressed, including market efficiency and the accuracy of models of expected returns, with a particular focus on variances, covariances, and the price of risk according to the Capital Asset Pricing Model.

Download or read book Anticipating Correlations written by Robert Engle and published by Princeton University Press. This book was released on 2009-01-19 with total page 176 pages. 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.

Download or read book Asymmetric Effects of Return and Volatility on Correlation between International Equity Markets written by Abderrahim Taamouti and published by . This book was released on 2009 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: How the correlation between equity returns behaves during market turmoils has been an issue of discussion in the international finance literature. Some research suggest an increase of correlation during volatile periods [Ang and Bekaert, 2002], while others argue its stability [Forbes and Rigobon, 2002]. In this paper, we study the impact of returns and volatility on correlation between international equity markets. Our objective is to determine if there is any asymmetry in correlation and identify the main explanation for this asymmetry. Within a framework of autoregressive models we quantify the relationship between return, volatility, and correlation using the generalized impulse response function and we test for the asymmetries in the return-correlation and volatility-correlation relationships. We also examine the implications of these asymmetric effects for the optimal international portfolio. Empirical evidence using weekly data on US, Canada, UK, and France equity indices, show that without taking into account the effect of return, there is an asymmetric impact of volatility on correlation. The volatility seems to have more impact on correlation during market upturn periods than during downturn periods. However, once we introduce the effect of return, the asymmetric impact of volatility on correlation disappears. These observations suggest that, the relation between volatility and correlation is an association rather than a causality. The strong increase in the correlation is driven by the market direction and the level of return rather than the level of the volatility. These results are confirmed using some tests of the asymmetry in volatility-correlation and return-correlation relationships in separate models and then in a joint model. Finally, we find that taking into account the asymmetric effect of return on correlation leads to an average financial gain ranged between 3.35 and 37.25 basis points for optimal international diversification.

Download or read book Correlation and Volatility Asymmetries in International Equity Markets written by CFA O'Toole (Randy) and published by . This book was released on 2013 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The co-movement of international equity markets in different return environments is examined using estimates of realized correlation and volatility. Using a simple ordinary least squares (OLS) regression framework, correlations are shown to be similarly elevated in periods characterized by extreme returns in both up and down markets, which contradicts a body of extant research that finds correlations increase in down markets but not in up markets. In contrast, volatility is much greater in down markets than in up markets. This suggests that it is not a lack of diversification that matters for comparative performance in bear markets, but rather the relative magnitude of negative returns typically experienced during such periods.

Available in PDF, EPUB and Kindle. Book excerpt: The paper investigates the degree of sensitivity of international equity market returns, using MSCI indices as widely tracked global equity benchmarks of stock exchanges, traded throughout the world. In particular using a time-varying methodology, the research examines whether the returns of developed international stock exchange markets (Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the UK and the USA) are each associated with movements of MSCI World Index in order to see the level of bilateral influence between equity markets, affected by globalization processes. In this paper the author uses, first, the correlation analysis applied to stock exchange markets in order to highlight the dynamic of financial market globalization. Second, the author uses the estimation model of security markets convergence based on the bilateral differences of their returns, suggested and developed by Frazer (1994; 2008). The model contains the Kalman filter and, as a consequence, this model accommodates fundamental shifts in the bilateral relationships. However, there is no study where the Kalman filter methodology is used to examine time-varying convergence of international stock exchange market returns relative to MSCI World Index. The results of research show that all analyzed developed equity markets are moving toward greater integration in terms of increasing correlation. Moreover, all analyzed markets are interdependent and affected by globalization processes, showing strong and lasting relationships between each other. However, bilateral convergence of international equity markets is not an equal process, where different cluster of markets are engaged in different manners. Some of equity markets have less influence on other market' returns in global context, suggesting that bilateral convergence is not a homogeneous process. Furthermore, the findings suggest including industry portfolio diversification approach instead of geographical diversification in asset-allocation models.

Download or read book Data Science for Financial Econometrics written by Nguyen Ngoc Thach and published by Springer Nature. This book was released on 2020-11-13 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an overview of state-of-the-art econometric techniques, with a special emphasis on financial econometrics. There is a major need for such techniques, since the traditional way of designing mathematical models – based on researchers’ insights – can no longer keep pace with the ever-increasing data flow. To catch up, many application areas have begun relying on data science, i.e., on techniques for extracting models from data, such as data mining, machine learning, and innovative statistics. In terms of capitalizing on data science, many application areas are way ahead of economics. To close this gap, the book provides examples of how data science techniques can be used in economics. Corresponding techniques range from almost traditional statistics to promising novel ideas such as quantum econometrics. Given its scope, the book will appeal to students and researchers interested in state-of-the-art developments, and to practitioners interested in using data science techniques.
