This book was released on 2006 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equity returns are more dependent in bear markets than in bull markets. This phenomenon known as asymmetric dependence is well documented in many previous studies including Erb et al (1994), Longin and Solnik (2001), Ang and Bekaert (2002), Ang and Chen (2002), Das and Uppal (2003), Patton (2004) and references therein. By reformulating the extreme exceedance correlation result of Longin and Solnik (2001) in an equivalent fashion as tail dependence, we show analytically that a multivariate GARCH model or a regime switching (RS) model based on normal innovations cannot reproduce this asymmetric dependence. We propose an alternative model which allows tail dependence for lower returns and keeps tail independence for upper returns. This model is applied to international equity and bond markets from two pairs of countries, the two leading markets in North-America (US and Canada) and two major markets of the Euro zone (France and Germany) to investigate their dependence structure. It includes one normal regime in which dependence is symmetric and a second regime characterized by asymmetric dependence. Empirical results show that the dependence between equities and bonds is low even in the same country, while the dependence between international assets of the same type is large in both regimes. The cross-country dependence is specially large in the asymmetric regime. This phenomenon possibly is due to the nonlinearity in dependence of international returns characterized by the presence of extreme dependence that is absent in the tail of a multivariate normal distribution. Exchange rate volatility seems to be a factor contributing to asymmetric dependence. With the introduction of a fixed exchange rate the dependence between France and Germany becomes less asymmetric and more normal than before. High exchange rate volatility is associated with a high level of asymmetry. Monte Carlo Tests confirm the presence of asymmetric dependence in both pairs of countries.

This book was released on 2008 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equity returns are more dependent in bear markets than in bull markets. Previous studies have argued that a multivariate GARCH model or a regime switching (RS) model based on normal innovations could reproduce this asymmetric extreme dependence. We show analytically that it cannot be the case. We propose an alternative model that allows for tail dependence in lower returns and keeps tail independence for upper returns. This model is applied to international equity and bond markets to investigate their dependence structure. It includes one normal regime in which dependence is symmetric and a second regime characterized by a symmetric dependence. Empirical results show that the dependence between equities and bonds is low even in the same country, while the dependence between international assets of the same type is large in both regimes. The cross-country dependence is especially large in the asymmetric regime. Exchange rate volatility seems to be a factor contributing to asymmetric dependence. With the introduction of a fixed exchange rate the dependence between France and Germany becomes less asymmetric and more normal than before. High exchange rate volatility is associated with a high level of asymmetry. Empirical phenomena such as home bias investment and flight to safety are amplified by asymmetric dependence through coskewness. For a US investor who holds US and Canadian bonds and equities, the share invested in Canada increases with the asymmetric dependence since the Canadian market in our sample is less risky. However, when the adjustment for perceived risk is made to take into account the asymmetric information the result changes and asymmetric dependence increases the home investment. A similar behavior is observed for the bond and equity trade-off. In the asymmetric dependence regime, the very risk-averse agent increases the fraction of its wealth in bonds.

Available in PDF, EPUB and Kindle. Book excerpt: Avoid downturn vulnerability by managing correlation dependency Asymmetric Dependence in Finance examines the risks and benefits of asset correlation, and provides effective strategies for more profitable portfolio management. Beginning with a thorough explanation of the extent and nature of asymmetric dependence in the financial markets, this book delves into the practical measures fund managers and investors can implement to boost fund performance. From managing asymmetric dependence using Copulas, to mitigating asymmetric dependence risk in real estate, credit and CTA markets, the discussion presents a coherent survey of the state-of-the-art tools available for measuring and managing this difficult but critical issue. Many funds suffered significant losses during recent downturns, despite having a seemingly well-diversified portfolio. Empirical evidence shows that the relation between assets is much richer than previously thought, and correlation between returns is dependent on the state of the market; this book explains this asymmetric dependence and provides authoritative guidance on mitigating the risks. Examine an options-based approach to limiting your portfolio's downside risk Manage asymmetric dependence in larger portfolios and alternate asset classes Get up to speed on alternative portfolio performance management methods Improve fund performance by applying appropriate models and quantitative techniques Correlations between assets increase markedly during market downturns, leading to diversification failure at the very moment it is needed most. The 2008 Global Financial Crisis and the 2006 hedge-fund crisis provide vivid examples, and many investors still bear the scars of heavy losses from their well-managed, well-diversified portfolios. Asymmetric Dependence in Finance shows you what went wrong, and how it can be corrected and managed before the next big threat using the latest methods and models from leading research in quantitative finance.

Download or read book Dynamic Copulas for Finance written by Valentin Braun and published by BoD – Books on Demand. This book was released on 2011 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions of financial securities are crucial to determine possible portfolio losses. Although this fact is well understood, two questions remain: What causes changes in the dependence structure of financial assets? How can fluctuating dependencies be measured? The most common approach to identify the amplitude of financial assets' interactions are linear correlation coefficients. However, they fail to comprise shifts in the dependence structure. Alternatively, Copulas are a more flexible dependence measurement. This book focuses on the development of Dynamic Copula frameworks by implementing stochastic parameters into Archimedian and Elliptical Copula functions. In contrast to static correlation measures, the Dynamic Copulas are able to replicate unstable financial market interactions. Various Dynamic Copulas are applied to global stock, bond, commodity and exchange rate data to calculate the correlation time paths, which explain financial market reactions to economic shocks. Furthermore, the interactions of dependencies, volatility and returns are analyzed, to determine the efficiency of portfolio diversification in regards to wealth protection. Portfolio risks are estimated through Dynamic Copulas to demonstrate their abilities to replicate financial market interactions accurately. Additionally, this analysis reveals the impact of changing dependence intensities on the magnitude of possible portfolio losses. Finally, the Dynamic Copulas are utilized to allocate higher moment optimal portfolios. This examination emphasizes the effect of inaccurate correlation estimates on the portfolio choice.

Available in PDF, EPUB and Kindle. Book excerpt: Emerging Markets and the Global Economy investigates analytical techniques suited to emerging market economies, which are typically prone to policy shocks. Despite the large body of emerging market finance literature, their underlying dynamics and interactions with other economies remain challenging and mysterious because standard financial models measure them imprecisely. Describing the linkages between emerging and developed markets, this collection systematically explores several crucial issues in asset valuation and risk management. Contributors present new theoretical constructions and empirical methods for handling cross-country volatility and sudden regime shifts. Usually attractive for investors because of the superior growth they can deliver, emerging markets can have a low correlation with developed markets. This collection advances your knowledge about their inherent characteristics. Foreword by Ali M. Kutan Concentrates on post-crisis roles of emerging markets in the global economy Reports on key theoretical and technical developments in emerging financial markets Forecasts future developments in linkages among developed and emerging economies

Download or read book International Capital Flows written by Martin Feldstein and published by University of Chicago Press. This book was released on 2007-12-01 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent changes in technology, along with the opening up of many regions previously closed to investment, have led to explosive growth in the international movement of capital. Flows from foreign direct investment and debt and equity financing can bring countries substantial gains by augmenting local savings and by improving technology and incentives. Investing companies acquire market access, lower cost inputs, and opportunities for profitable introductions of production methods in the countries where they invest. But, as was underscored recently by the economic and financial crises in several Asian countries, capital flows can also bring risks. Although there is no simple explanation of the currency crisis in Asia, it is clear that fixed exchange rates and chronic deficits increased the likelihood of a breakdown. Similarly, during the 1970s, the United States and other industrial countries loaned OPEC surpluses to borrowers in Latin America. But when the U.S. Federal Reserve raised interest rates to control soaring inflation, the result was a widespread debt moratorium in Latin America as many countries throughout the region struggled to pay the high interest on their foreign loans. International Capital Flows contains recent work by eminent scholars and practitioners on the experience of capital flows to Latin America, Asia, and eastern Europe. These papers discuss the role of banks, equity markets, and foreign direct investment in international capital flows, and the risks that investors and others face with these transactions. By focusing on capital flows' productivity and determinants, and the policy issues they raise, this collection is a valuable resource for economists, policymakers, and financial market participants.
