Available in PDF, EPUB and Kindle. Book excerpt: We show that the pricing of idiosyncratic volatility (IV) is due to unaccounted systematic risk, which affects a large number of asset pricing anomalies. A single common IV component explains one third of variation in IV. Mispricing arises when sorting stocks by the part of IV predicted by exposure to the common IV component, but not when sorting by residual IV. We propose the return difference between stocks with high and low predicted IV, PIV, as a proxy for the missing risk factor. PIV is significantly related to the common components of the returns of several important anomaly-based trading strategies. Controlling for PIV helps explain the earnings surprise, net stock issues, profitability, as well as illiquidity anomalies, and completely explains the financial distress anomaly. Overall our results suggest that the IV puzzle reflects systematic risk related to the average stock volatility and credit risk.

Book Synopsis The Art of Smooth Pasting by : A. Dixit
Download or read book The Art of Smooth Pasting written by A. Dixit and published by Routledge. This book was released on 2013-11-12 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to widen the understanding of stochastic dynamic choice and equilibrium models. It offers a simplified and heuristic exposition of the theory of Brownian motion and its control or regulation, rendering such methods more accessible to economists who do not require a detailed, mathematical treatment of the subject. The main mathematical ideas are presented in a context which with which economists will be familiar. Using a binomial approach to Brownian motion, the mathematics is reduced to simple algebra, progressing to some equally simple limits. The starting point of the calculus of Brownian motion - 'Ito's Lemma' - emerges by analogy with the economics of risk-aversion. Conditions for the optimal regulation of Brownian motion, including the important, but often mysterious, 'smooth pasting' condition, are derived in a similar way. Each theoretical derivation is illustrated by developing a significant economic application, drawn mainly from recent research in macroeconomics and international economics.
Book Synopsis Idiosyncratic Volatility, Fundamentals, and Institutional Herding by : Eric C. Chang
Download or read book Idiosyncratic Volatility, Fundamentals, and Institutional Herding written by Eric C. Chang and published by . This book was released on 2005 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We offer evidence at both portfolio level and firm level that variations in idiosyncratic volatility are related to both behavioral and fundamental factors. Using Japanese data from 1975 to 2003, we show that both institutional herding and firm earnings are positively related to idiosyncratic volatility. We reject the hypothesis that institutional investors herd toward stocks with high idiosyncratic volatility and systematic risk. Our results suggest that a behavior story may explain the negative premium earned by high volatility stocks found by Ang et al. (2004). In addition to cross sectional results, we present preliminary results on the co-movement of dispersions of change in institutional ownership and return-on-asset with the market aggregate idiosyncratic volatility in the Japanese market. Our results, when related to evidence from the US market, suggest that investor behavior and stock fundamentals may both help explain the time-series pattern of market aggregate idiosyncratic volatility.

Available in PDF, EPUB and Kindle. Book excerpt: “Bali, Engle, and Murray have produced a highly accessible introduction to the techniques and evidence of modern empirical asset pricing. This book should be read and absorbed by every serious student of the field, academic and professional.” Eugene Fama, Robert R. McCormick Distinguished Service Professor of Finance, University of Chicago and 2013 Nobel Laureate in Economic Sciences “The empirical analysis of the cross-section of stock returns is a monumental achievement of half a century of finance research. Both the established facts and the methods used to discover them have subtle complexities that can mislead casual observers and novice researchers. Bali, Engle, and Murray’s clear and careful guide to these issues provides a firm foundation for future discoveries.” John Campbell, Morton L. and Carole S. Olshan Professor of Economics, Harvard University “Bali, Engle, and Murray provide clear and accessible descriptions of many of the most important empirical techniques and results in asset pricing.” Kenneth R. French, Roth Family Distinguished Professor of Finance, Tuck School of Business, Dartmouth College “This exciting new book presents a thorough review of what we know about the cross-section of stock returns. Given its comprehensive nature, systematic approach, and easy-to-understand language, the book is a valuable resource for any introductory PhD class in empirical asset pricing.” Lubos Pastor, Charles P. McQuaid Professor of Finance, University of Chicago Empirical Asset Pricing: The Cross Section of Stock Returns is a comprehensive overview of the most important findings of empirical asset pricing research. The book begins with thorough expositions of the most prevalent econometric techniques with in-depth discussions of the implementation and interpretation of results illustrated through detailed examples. The second half of the book applies these techniques to demonstrate the most salient patterns observed in stock returns. The phenomena documented form the basis for a range of investment strategies as well as the foundations of contemporary empirical asset pricing research. Empirical Asset Pricing: The Cross Section of Stock Returns also includes: Discussions on the driving forces behind the patterns observed in the stock market An extensive set of results that serve as a reference for practitioners and academics alike Numerous references to both contemporary and foundational research articles Empirical Asset Pricing: The Cross Section of Stock Returns is an ideal textbook for graduate-level courses in asset pricing and portfolio management. The book is also an indispensable reference for researchers and practitioners in finance and economics. Turan G.

Book Synopsis A Model-Independent Measure of Aggregate Idiosyncratic Risk by : Turan G. Bali
Download or read book A Model-Independent Measure of Aggregate Idiosyncratic Risk written by Turan G. Bali and published by . This book was released on 2012 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper introduces a model-independent measure of aggregate idiosyncratic risk based on the mean-variance portfolio theory and the concept of gain from portfolio diversification. With the new approach, there is no need to estimate the covariance terms or the industry-level or firm-level beta coefficients when constructing the average idiosyncratic risk at the industry- or firm-level. Since there is no gain from diversification when the correlations among individual stocks equal one, the variance of the portfolio with perfectly correlated securities contains systematic risk and idiosyncratic risk of the securities in the portfolio. We also think that the stock market index can be viewed as a fully diversified portfolio, which does not contain any idiosyncratic risk. Since the market portfolio contains a large number of stocks, enough diversification gains are achieved and the idiosyncratic risk contributes nothing to the total risk of the market portfolio. That is, the risk of this well-diversified portfolio is due solely to the systematic risk of the securities in the portfolio. The new measure of average idiosyncratic volatility is defined as the difference between the variance of the non-diversified portfolio and the variance of the fully diversified portfolio. We present two versions of the new methodology; one decomposing total risk into firm and market variance, and the other decomposing total risk into firm, industry, and market variance. The statistical results and graphical analyses provide strong evidence that there are significant level and trend differences between the average idiosyncratic volatility measures of Campbell, Lettau, Malkiel, and Xu (2001, CLMX) and the new methodology. Although both approaches indicate a noticeable increase in the firm-level idiosyncratic risk, the volatility measure of CLMX is greater and has a stronger upward trend than the new idiosyncratic volatility measure. The analytical and empirical results show that the significant upward trend in the differences of the two idiosyncratic volatility measures is related to the increase in the cross-sectional dispersion of the volatility of individual stocks.
Book Synopsis Stochastic Idiosyncratic Cash Flow Risk and Real Options by : Harjoat Singh Bhamra
Download or read book Stochastic Idiosyncratic Cash Flow Risk and Real Options written by Harjoat Singh Bhamra and published by . This book was released on 2016 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stocks with high idiosyncratic volatility perform poorly relative to low idiosyncratic volatility stocks. We offer a novel explanation of this anomaly based on real options, which is consistent with earlier findings on idiosyncratic volatility (the positive contemporaneous relation between firm-level stock returns and idiosyncratic volatility). Our approach is based on introducing stochastic idiosyncratic cash flow risk into an equity valuation model of firms with growth options. Within our model, a firm's systematic risk depends on the delta of its growth option. The growth option's delta is lower when idiosyncratic volatility rises, driving down the firm's systematic risk and hence its expected return - firms with higher idiosyncratic volatility therefore have lower expected returns. Our model additionally offers the following novel empirical predictions: (i) returns correlate positively with idiosyncratic volatility during intervals between large changes in idiosyncratic volatility (the switch effect), and (ii) the anomalies and the switch effect are stronger for firms with more real options and which undergo larger changes in idiosyncratic volatility. Empirical results support the predictions of our model.
Book Synopsis Idiosyncratic Cash Flows and Systematic Risk by : Ilona Babenko
Download or read book Idiosyncratic Cash Flows and Systematic Risk written by Ilona Babenko and published by . This book was released on 2015 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: We show that unpriced cash flow shocks contain information about future priced risk. A positive idiosyncratic shock decreases the sensitivity of firm value to priced risk factors and simultaneously increases firm size and idiosyncratic risk. A simple model can therefore explain book-to-market and size anomalies, as well as the negative relation between idiosyncratic volatility and stock returns. Using the model, we identify firms for which anomalies must be stronger and confirm this relation empirically. More generally, our results imply that any economic variable correlated with the history of idiosyncratic shocks can help to explain expected stock returns.
Book Synopsis Stochastic Volatility in Financial Markets by : Antonio Mele
Download or read book Stochastic Volatility in Financial Markets written by Antonio Mele and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stochastic Volatility in Financial Markets presents advanced topics in financial econometrics and theoretical finance, and is divided into three main parts. The first part aims at documenting an empirical regularity of financial price changes: the occurrence of sudden and persistent changes of financial markets volatility. This phenomenon, technically termed `stochastic volatility', or `conditional heteroskedasticity', has been well known for at least 20 years; in this part, further, useful theoretical properties of conditionally heteroskedastic models are uncovered. The second part goes beyond the statistical aspects of stochastic volatility models: it constructs and uses new fully articulated, theoretically-sounded financial asset pricing models that allow for the presence of conditional heteroskedasticity. The third part shows how the inclusion of the statistical aspects of stochastic volatility in a rigorous economic scheme can be faced from an empirical standpoint.

Book Synopsis Idiosyncratic Risk and Reit Returns by : Joseph T. L. Ooi
Download or read book Idiosyncratic Risk and Reit Returns written by Joseph T. L. Ooi and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The volatility of a stock returns can be decomposed into market and firm-specific volatility, with the former commonly known as systematic risk and the later as idiosyncratic risk. This study examines the relevance of idiosyncratic risk in explaining the monthly cross-sectional returns of REIT stocks. Contrary to the CAPM theory, a significant positive relationship is found between idiosyncratic volatility and the cross-sectional returns. This suggests that firm-specific risk matters in REIT pricing. The regression results further show that once idiosycratic risk is controlled for in the asset-pricing model, the size and book-to-market equity ratio factors ceased to be significant. The explanatory power of the momentum effect remains robust in the presence of idiosyncratic risk.

Book Synopsis Information in the Idiosyncratic Volatility of Small Firms by : David P. Brown
Download or read book Information in the Idiosyncratic Volatility of Small Firms written by David P. Brown and published by . This book was released on 2004 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-systematic volatilities of small firms are special as predictors of stock returns. They are positively related with future returns on all age and size portfolios. They dominate systematic volatility, big-firm volatility and other volatilities. And there is strong evidence that idiosyncratic risk is priced in small-firm returns. Small-firm volatility as a predictor of big-firm returns is in part a proxy for systematic volatility and consumption-wealth ratio. We rule out several hypotheses, including a liquidity premium, as potential explanations of our results, but not the idea that small-firm idiosyncratic volatility is correlated with the risk of the total investor portfolio, which includes non-equity assets.
