Book Description
In this paper, we provide a model-free test for asymmetric correlations which suggest stocks tend to have greater correlations with the market when the market goes down than when it goes up. We also provide such tests for asymmetric betas and covariances. In addition, we evaluate the economic significance of asymmetric correlations by answering the question that what is the utility gain for an investor who switches from a belief of symmetric stock returns into a belief of asymmetric returns. Applying our methodology to three portfolios grouped by size, Fama and French's size and book-to-market, and industry, we find that asymmetries show up in sample estimates for all the portfolios, but they are statistically ignificant primarily for small size portfolios. Nevertheless, asymmetries are of substantial economic importance for an investor who switches her symmetry belief into an asymmetric one, irrespective of the portfolios.

Book Description
In Asymmetric Returns, financial expert Alexander Ineichen elevates the critical discussion about alpha versus beta and absolute returns versus relative returns. He argues that controlling downside volatility is a key element in asset management if sustainable positive compounding of capital and financial survival are major objectives. Achieving sustainable positive absolute returns are the result of taking and managing risk wisely, that is, an active risk management process where risk is defined in absolute terms and changes in the market place are accounted for. The result of an active risk management process-when successful-is an asymmetric return profile, that is, more and higher returns on the upside and fewer and lower returns on the downside. Ineichen claims that achieving Asymmetric Returns is the future of active asset management. Alexander M. Ineichen, CFA, CAIA, is Managing Director and Senior Investment Officer for the Alternative Investment Solutions team, a key provider within Alternative and Quantitative Investments, itself a business within UBS Global Asset Management. He is also on the Board of Directors of the Chartered Alternative Investment Analyst Association (CAIAA). Ineichen is the author of the two UBS research publications In Search of Alpha—Investing in Hedge Funds (October 2000) and The Search for Alpha Continues—Do Fund of Hedge Funds Add Value? (September 2001). As of 2006 these two reports were the most often printed research papers in the documented history of UBS. He is also author of the widely popular Absolute Returns—The Risk and Opportunities of Hedge Fund Investing, also published by John Wiley & Sons.

Book Description
A comprehensive, up-to-date textbook on nonparametric methods for students and researchers Until now, students and researchers in nonparametric and semiparametric statistics and econometrics have had to turn to the latest journal articles to keep pace with these emerging methods of economic analysis. Nonparametric Econometrics fills a major gap by gathering together the most up-to-date theory and techniques and presenting them in a remarkably straightforward and accessible format. The empirical tests, data, and exercises included in this textbook help make it the ideal introduction for graduate students and an indispensable resource for researchers. Nonparametric and semiparametric methods have attracted a great deal of attention from statisticians in recent decades. While the majority of existing books on the subject operate from the presumption that the underlying data is strictly continuous in nature, more often than not social scientists deal with categorical data—nominal and ordinal—in applied settings. The conventional nonparametric approach to dealing with the presence of discrete variables is acknowledged to be unsatisfactory. This book is tailored to the needs of applied econometricians and social scientists. Qi Li and Jeffrey Racine emphasize nonparametric techniques suited to the rich array of data types—continuous, nominal, and ordinal—within one coherent framework. They also emphasize the properties of nonparametric estimators in the presence of potentially irrelevant variables. Nonparametric Econometrics covers all the material necessary to understand and apply nonparametric methods for real-world problems.

Book Description
There is much evidence in the literature that the volatilities of equity returns show evidence of asymmetric responses to good and bad news. At the same time, there is evidence that the unconditional distribution of stock returns is asymmetric as well. This paper examines the effects of asymmetries of various forms on the accuracy of value at risk models. We compare the value at risk estimates derived from models which assume both a symmetric unconditional distribution of returns and a symmetric response of volatility to good and bad news, with models which explicitly allow for each class of asymmetries. We find that, between the two types of asymmetry considered, the asymmetry in the unconditional distribution is the more important feature. Use of the semi-variance, which allows for this feature, is shown to provide more stable and more reliable value at risk estimates than simple and more complex models that do not.

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
This paper examines the hypothesis that both stock returns and volatility are asymmetrical functions of past information derived from domestic and US stock market news. By employing a double-threshold regression GARCH model to investigate four major index return series, we find significant evidence to sustain the asymmetrical hypothesis of stock returns. Specifically, evidence strongly supports the hypothesis that stock index returns are positively correlated with a composite of stock return news, which is obtained by a weighted average of the lagged domestic and US stock index returns. Moreover, we find that negative news will cause a larger decline in a national stock return than will an equal magnitude of good news. This also holds true for the conditional variance. The variance appears to be more volatile and persistent when bad news hits the market than when good news does. Consistent with existing literature, asymmetries in stock returns are not independent of asymmetries in volatility since a larger adjustment in stock prices to bad news is likely to cause domestic investors to change the debt-equity ratio, leading to higher volatility in stock market.

Book Description
We apply a new approach to a new panel data set on bilateral gross cross-border equity flows between 14 countries, 1989-96. The model integrates elements of the finance literature on portfolio composition and the international macroeconomics and asset trade literature. Gross asset flows depend on market size in both source and destination country as well as trading costs, in which both information and the transaction technology play a role. Distance proxies some information costs, and other variables explicitly represent information transmission, an information asymmetry between domestic and foreign investors, and the efficiency of transactions. The remarkably good results have strong implications for theories of asset trade. We find that the geography of information is the main determinant of the pattern of international transactions, while there is little support in our data for diversification and return-chasing motives for transactions."--Authors.

Book Description
Time-varying factor loadings exhibit pronounced asymmetry in the cross section of stock returns. To capture this asymmetry, we develop regime-switching versions of the CAPM and the Fama French three-factor model, allowing both factor loadings and predictable risk premiums to switch across regimes. We estimate the models jointly on the decile book-to-market portfolios, together with the market portfolio to investigate the role of asymmetric risk in the book-to-market premium. We find that betas of value stocks increase significantly during bear market episodes. However, we still reject that the book-to-market premium is equal to zero for both the regime-switching conditional CAPM and the Fama-French model, even in the presence of regimes.
