Book excerpt: In recent years there has been a lot of debate about volatility, the risk-on/risk-off market with a focus on macro and factor risks. Our research uses the methodology of Campbell et al. (2001) to break down the total volatility in US equities into the three components of Market, Industry and Firm (idiosyncratic risk), and analyzes the trends in their share over 2005-2014. The value addition from active stock selection is greater when idiosyncratic risk becomes a bigger component of total volatility. Our main conclusion is that there is a strong payoff to stock selection even in the post-financial crisis era where markets often think of risk only in terms of risk-on/risk-off. The share of idiosyncratic risk indicating benefits of stock selection decreased a lot during the crisis. It is now at the highest level since the start of the financial crisis, though still much lower than in the pre-crisis years. Total volatility increased ~4X during the crisis and is now lower than pre-crisis. The share of idiosyncratic volatility dipped sharply during the crisis, but remains the largest component (> 60%) of total volatility for an equity investor. The share of market volatility increased ~4X during the crisis to become the largest component. Currently much lower, it is still 2X prior-recession average and higher than the long-term average. Sector volatility has shown a consistent decrease over 2005-2014, and is now the smallest share of total volatility. Average pair-wise stock correlation in the S&P 500 increased ~3X from pre-crisis years through 2010, and is now 2X pre-recession average. The power of the market model in explaining stock returns, increased sharply from 22% pre-crisis to more than 50% in 2010, and has since decreased and remained consistent at ~30%. We also found a strong negative correlation between all components of volatility and contemporaneous GDP growth, with the information decay being fastest for idiosyncratic volatility. Idiosyncratic risk as a share of total stock volatility, though lower than pre-crisis levels, is the highest since the financial crisis. It remains the largest share of total U.S. equity volatility providing a strong justification for stock selection and active management.

Download or read book Financial and Macroeconomic Connectedness written by Francis X. Diebold and published by Oxford University Press. This book was released on 2015-02-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Connections among different assets, asset classes, portfolios, and the stocks of individual institutions are critical in examining financial markets. Interest in financial markets implies interest in underlying macroeconomic fundamentals. In Financial and Macroeconomic Connectedness, Frank Diebold and Kamil Yilmaz propose a simple framework for defining, measuring, and monitoring connectedness, which is central to finance and macroeconomics. These measures of connectedness are theoretically rigorous yet empirically relevant. The approach to connectedness proposed by the authors is intimately related to the familiar econometric notion of variance decomposition. The full set of variance decompositions from vector auto-regressions produces the core of the 'connectedness table.' The connectedness table makes clear how one can begin with the most disaggregated pair-wise directional connectedness measures and aggregate them in various ways to obtain total connectedness measures. The authors also show that variance decompositions define weighted, directed networks, so that these proposed connectedness measures are intimately related to key measures of connectedness used in the network literature. After describing their methods in the first part of the book, the authors proceed to characterize daily return and volatility connectedness across major asset (stock, bond, foreign exchange and commodity) markets as well as the financial institutions within the U.S. and across countries since late 1990s. These specific measures of volatility connectedness show that stock markets played a critical role in spreading the volatility shocks from the U.S. to other countries. Furthermore, while the return connectedness across stock markets increased gradually over time the volatility connectedness measures were subject to significant jumps during major crisis events. This book examines not only financial connectedness, but also real fundamental connectedness. In particular, the authors show that global business cycle connectedness is economically significant and time-varying, that the U.S. has disproportionately high connectedness to others, and that pairwise country connectedness is inversely related to bilateral trade surpluses.
Download or read book Dispersion and Volatility in Stock Returns written by John Y. Campbell and published by . This book was released on 1998 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies three different measures of monthly stock market volatility: the time-series volatility of daily market returns within the month; the cross-sectional volatility or 'dispersion' of daily returns on industry portfolios, relative to the market, within the month; and the dispersion of daily returns on individual firms, relative to their industries, within the month. Over the period 1962-97 there has been a noticeable increase in firm-level volatility relative to market volatility. All the volatility measures move together in a countercyclical fashion. While market volatility tends to lead the other volatility series, industry-level volatility is a particularly important leading indicator for the business cycle.

Download or read book Market Risk Analysis Value at Risk Models written by Carol Alexander and published by John Wiley & Sons. This book was released on 2009-02-09 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by leading market risk academic, Professor Carol Alexander, Value-at-Risk Models forms part four of the Market Risk Analysis four volume set. Building on the three previous volumes this book provides by far the most comprehensive, rigorous and detailed treatment of market VaR models. It rests on the basic knowledge of financial mathematics and statistics gained from Volume I, of factor models, principal component analysis, statistical models of volatility and correlation and copulas from Volume II and, from Volume III, knowledge of pricing and hedging financial instruments and of mapping portfolios of similar instruments to risk factors. A unifying characteristic of the series is the pedagogical approach to practical examples that are relevant to market risk analysis in practice. All together, the Market Risk Analysis four volume set illustrates virtually every concept or formula with a practical, numerical example or a longer, empirical case study. Across all four volumes there are approximately 300 numerical and empirical examples, 400 graphs and figures and 30 case studies many of which are contained in interactive Excel spreadsheets available from the the accompanying CD-ROM . Empirical examples and case studies specific to this volume include: Parametric linear value at risk (VaR)models: normal, Student t and normal mixture and their expected tail loss (ETL); New formulae for VaR based on autocorrelated returns; Historical simulation VaR models: how to scale historical VaR and volatility adjusted historical VaR; Monte Carlo simulation VaR models based on multivariate normal and Student t distributions, and based on copulas; Examples and case studies of numerous applications to interest rate sensitive, equity, commodity and international portfolios; Decomposition of systematic VaR of large portfolios into standard alone and marginal VaR components; Backtesting and the assessment of risk model risk; Hypothetical factor push and historical stress tests, and stress testing based on VaR and ETL.
Download or read book Are Volatility Spillovers Between Currency and Equity Market Driven by Economic States Evidence from the US Economy written by Klaus Grobys and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the volatility spillovers between the foreign exchange rate markets of three of the USA's major trading partners and the US stock market, utilizing the forecast-error variance decomposition framework of a VAR model proposed by Diebold and Yilmaz (2009). The empirical results, based on a data set covering the period 1986-2014 suggest that the level of total volatility spillover effects is high only when they precede periods of economic turbulence. If the economy is quiet, volatility spillover effects are virtually non-existent.

Download or read book Government Size and Output Volatility written by Xavier Debrun and published by . This book was released on 2008 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prior to the launch of the euro, academics and policymakers were concerned that the loss of the monetary policy instrument would deprive participating countries of a vital tool to respond to country-specific economic shocks. This concern was rooted in the generally accepted proposition that market-based adjustment channels - i.e. labour mobility and capital flows - tended to be weaker among euro area countries than among regions of existing monetary unions such as the United States. Automatic stabilizers had long been regarded as playing a key role in macroeconomic stabilization. In particular, they were generally considered as having contributed significantly to the decrease of output volatility witnessed in Europe and in the United States after World War II, when the size of governments increased substantially on both sides of the Atlantic. Hence it was hoped that improved national fiscal policy could partly make up for the loss of monetary policy in stabilizing national macroeconomic conditions. The aim of the paper is to discuss this issue in the light of recent experience.
