Book Description
"Clearly elucidates extreme financial risks associated with rare events such as financial crashes. The highlight of the book is the delineation of various copulas in conjunction with financial dependences among different assets of a portfolio. In particular, the insightful discussion on quadrant and orthant dependences casts new light on the connection between marginal models and financial dependence...brings a vivid portrayal of the subject." -- MATHEMATICAL REVIEWS

Book Description
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.

Book Description
Each financial crisis calls for — by its novelty and the mechanisms it shares with preceding crises — appropriate means to analyze financial risks. In Extreme Financial Risks and Asset Allocation, the authors present in an accessible and timely manner the concepts, methods, and techniques that are essential for an understanding of these risks in an environment where asset prices are subject to sudden, rough, and unpredictable changes. These phenomena, mathematically known as “jumps”, play an important role in practice. Their quantitative treatment is generally tricky and is sparsely tackled in similar books. One of the main appeals of this book lies in its approachable and concise presentation of the ad hoc mathematical tools without sacrificing the necessary rigor and precision.This book contains theories and methods which are usually found in highly technical mathematics books or in scattered, often very recent, research articles. It is a remarkable pedagogical work that makes these difficult results accessible to a large readership. Researchers, Masters and PhD students, and financial engineers alike will find this book highly useful.

Book Description
The paper investigates the portfolio allocation effects of increased asset co-movements during extreme market downturns. We develop a model for the state variables underlying the stock price process that allows for increased and asymmetric dependence between extreme return realizations. We isolate the portfolio hedging demands that arise due to extreme co-movements and find a substantial shift of the portfolio holdings toward the risk-free asset. Ignoring the dependence between extreme events gives rise to sizeable economic losses. It penalizes investors for holding levered positions, and reduces the gains from diversification. These findings are robust along different specifications of the utility function, varying levels of risk aversion, and alternative modeling assumptions of extreme co-movements and conditional correlation.

Book Description
The increasing presence of investors and financial intermediaries in commodity markets, together with the huge increase in the volatility of commodity prices, have renewed the interest in commodities and commodity derivatives. In the last decade, a better understanding of the behavior of commodity prices and their idiosyncratic statistical features has emerged as a relevant financial and policy topic. This book tries to provide new insights, first, to analyze the multivariate distribution of commodity returns and its impact on portfolio selection and tail risk measures; and, second, to price commodity derivatives under the presence of non-Gaussian shocks in a continuous time framework.

Book Description
Since the formalization of asset allocation in 1952 with the publication of Portfolio Selection by Harry Markowitz, there have been great strides made to enhance the application of this groundbreaking theory. However, progress has been uneven. It has been punctuated with instances of misleading research, which has contributed to the stubborn persistence of certain fallacies about asset allocation. A Practitioner's Guide to Asset Allocation fills a void in the literature by offering a hands-on resource that describes the many important innovations that address key challenges to asset allocation and dispels common fallacies about asset allocation. The authors cover the fundamentals of asset allocation, including a discussion of the attributes that qualify a group of securities as an asset class and a detailed description of the conventional application of mean-variance analysis to asset allocation.. The authors review a number of common fallacies about asset allocation and dispel these misconceptions with logic or hard evidence. The fallacies debunked include such notions as: asset allocation determines more than 90% of investment performance; time diversifies risk; optimization is hypersensitive to estimation error; factors provide greater diversification than assets and are more effective at reducing noise; and that equally weighted portfolios perform more reliably out of sample than optimized portfolios. A Practitioner's Guide to Asset Allocation also explores the innovations that address key challenges to asset allocation and presents an alternative optimization procedure to address the idea that some investors have complex preferences and returns may not be elliptically distributed. Among the challenges highlighted, the authors explain how to overcome inefficiencies that result from constraints by expanding the optimization objective function to incorporate absolute and relative goals simultaneously. The text also explores the challenge of currency risk, describes how to use shadow assets and liabilities to unify liquidity with expected return and risk, and shows how to evaluate alternative asset mixes by assessing exposure to loss throughout the investment horizon based on regime-dependent risk. This practical text contains an illustrative example of asset allocation which is used to demonstrate the impact of the innovations described throughout the book. In addition, the book includes supplemental material that summarizes the key takeaways and includes information on relevant statistical and theoretical concepts, as well as a comprehensive glossary of terms.

Book Description
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.
