Book Synopsis The Time-Series Behavior and Pricing of Idiosyncratic Volatility by : Paul Brockman
Download or read book The Time-Series Behavior and Pricing of Idiosyncratic Volatility written by Paul Brockman and published by . This book was released on 2008 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent research on idiosyncratic volatility has documented three main empirical findings. First, Campbell, Lettau, Malkiel, and Xu (2001) show that idiosyncratic volatility exhibits an upward trend between 1962 and 1997. Second, Goyal and Santa-Clara (2003) find that aggregate measures of idiosyncratic volatility predict one-month-ahead excess market returns from 1962 to 1999. Third, Ang, Hodrick, Xing, and Zhang (2006) report a negative and significant relation between idiosyncratic volatility and cross-sectional stock returns from 1963 to 2000. We re-examine these three findings using a 37-year holdout sample of daily returns from 1926 to 1962. We find robust empirical evidence of (1) a statistically significant downward trend in idiosyncratic volatility, (2) an insignificant relation between average idiosyncratic volatility and one-month-ahead excess market returns, and (3) a highly significant inverse relation between idiosyncratic volatility and cross-sectional stock returns. These results shed new light on the time-series behavior and pricing of idiosyncratic volatility.

Book excerpt: This study examines the importance of idiosyncratic volatility in asset pricing for Australian stock returns from January 2002 to December 2010. Inspired by work from the early 1990s which found that portfolios constructed to mimic common risk factors explained significant variations in US stock returns, we construct an idiosyncratic volatility mimicking factor to explore the explanatory power of this factor in the Australian stock market. Our results indicate that (a) the idiosyncratic volatility mimicking factor is priced and positively related to the stock returns for the sample period, (b) the explanatory power of the idiosyncratic volatility mimicking factor remains robust in both time-series and cross-sectional analysis, and (c) big size stocks are systematically riskier than small size stocks.
Book Synopsis Idiosyncratic Volatility and the Pricing of Poorly-Diversified Portfolios by : Joëlle Miffre
Download or read book Idiosyncratic Volatility and the Pricing of Poorly-Diversified Portfolios written by Joëlle Miffre and published by . This book was released on 2015 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This article examines the role of idiosyncratic volatility in explaining the cross-sectional variation of size- and value-sorted portfolio returns. We show that the premium for bearing idiosyncratic volatility varies inversely with the number of stocks included in the portfolios. This conclusion is robust within various multifactor models based on size, value, past performance, liquidity and total volatility and also holds within an ICAPM specification of the risk-return relationship. Our findings thus indicate that investors demand an additional return for bearing the idiosyncratic volatility of poorly-diversified portfolios.

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 Is Idiosyncratic Volatility Risk Priced? Evidence from the Physical and Risk-Neutral Distributions by : Ali Boloor
Download or read book Is Idiosyncratic Volatility Risk Priced? Evidence from the Physical and Risk-Neutral Distributions written by Ali Boloor and published by . This book was released on 2014 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use simultaneous data from equity, index and option markets in order to estimate a single-factor market model in which idiosyncratic volatility is allowed to be priced. We model the index dynamics' physical distribution as a mean-reverting stochastic volatility process as in Heston (1993), and the equity returns as single-factor models with stochastic idiosyncratic volatility terms. We derive theoretically the underlying assets' risk-neutral distributions, and we estimate the parameters of both P and Q distributions using a joint likelihood function. We document the existence of a common factor structure in option implied idiosyncratic variances. We show that the average idiosyncratic variance, which proxies for the common factor, is priced in the cross section of equity returns, and that it reduces the pricing error when added to the Fama-French model. We find that the idiosyncratic volatilities differ under the P and Q measures, and we estimate the price of this idiosyncratic volatility risk, which turns out to be significantly different from zero for all the stocks in our sample. We construct portfolios that only load on the idiosyncratic variance, and we propose a measure of idiosyncratic variance risk premium. Further, we show that these premiums are not explained by the usual equity risk factors. Finally, we explore the implications of our results for the estimation of the conditional equity betas.
Book Synopsis The Common Factor in Idiosyncratic Volatility by : Bernard Herskovic
Download or read book The Common Factor in Idiosyncratic Volatility written by Bernard Herskovic and published by . This book was released on 2014 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: We show that firms' idiosyncratic volatility obeys a strong factor structure and that shocks to the common factor in idiosyncratic volatility (CIV) are priced. Stocks in the lowest CIV-beta quintile earn average returns 6.4% per year higher than those in the highest quintile. We provide evidence that the CIV factor is correlated with income risk faced by households. These three facts are consistent with a canonical incomplete markets heterogeneous-agent model. In the model, CIV is a priced state variable because an increase in idiosyncratic firm volatility raises the typical investor's marginal utility when markets are incomplete. The calibrated model matches the high degree of comovement in idiosyncratic volatilities, the CIV-beta return spread, and several other asset price moments.
Book Synopsis Patterns and Pricing of Idiosyncratic Volatility in French Stock Market by : Zhentao Liu
Download or read book Patterns and Pricing of Idiosyncratic Volatility in French Stock Market written by Zhentao Liu and published by . This book was released on 2017 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The current research is to investigate the time series behavior of idiosyncratic volatility (IVOL) and its role in asset pricing in France in a twenty-year testing period. Design/methodology/approach: We test for the presence of trends in aggregate idiosyncratic and market volatility using Bunzel and Vogelsang's (2005) t-dan test. We follow Bekaert et al. (2012) to test for regime shifts of both aggregate idiosyncratic and market volatilities. And then, we employ portfolio level analysis and cross-sectional univariate Fama-MacBeth regressions to examine the relationship between IVOL and cross-sectional stock returns in French stock market.Findings: First, we find that both idiosyncratic and market volatility do not exhibit long-term trends. Instead, their patterns are consistent with regime switching behavior. Second, though we initially find a strong significant negative IVOL effect in the French stock market which is robust in bi-variate Fama-MacBeth regressions, the negative IVOL effect is becoming marginal significant when we control for SIZE, BM, momentum, and short-term reversal simultaneously. Our new evidence suggests that there is a marginal IVOL effect in the French stock market adding to the increasing number of studies questioning the ubiquity of the negative IVOL puzzle.Originality/value: First, we present the first empirical evidence on examining the trends of both aggregate idiosyncratic and market volatilities, and the pricing role of IVOL in French stock market. We draw an attention for both academia and practitioners on an individual developed stock market. Second, we add new evidence to the mounting results questioning the ubiquity of the IVOL effect. This highlights the importance of country verification of so called anomalies in the US, even in developed markets. Finally, we confirm earlier evidence both aggregate idiosyncratic and market volatilities in the French stock market exhibits regime switching behavior rather than showing a long-term time trends.
Book Synopsis Idiosyncratic Volatility and Liquidity Costs by : David A. Lesmond
Download or read book Idiosyncratic Volatility and Liquidity Costs written by David A. Lesmond and published by . This book was released on 2009 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine the cross-sectional relation between idiosyncratic volatility (IV) and stock returns and find the results of AngHodrickXingZhang (2006) are critically dependent on the occurrence of zero returns that reflects an inflated measurement of IV. Specifically controlling for liquidity costs engendered in both the percentage of zero returns and the more direct bid-ask spread removes the ability of IV to predict future returns, contrary to SpiegelWang (2005) and Ang et al. (2006). Examining external shocks to liquidity due to reductions in the stated quotes after 1997 and 2001, shows a reduction in the occurrence of zero returns that is accompanied by a significant reduction in the pricing ability of IV. Restricting our analysis to those firms that experience less than 5 % zero returns during the period 1983 to 1996, when the overall pricing ability of IV is at a peak, shows no ability of IV to predict returns. The percentage of zero returns and its affect on IV measurement appears to be a missing component in the ongoing analysis of the pricing of IV.

Book Synopsis The Bid-Ask Bounce Effect and the Pricing of Cross-Sectional Idiosyncratic Volatility by : Bin Liu
Download or read book The Bid-Ask Bounce Effect and the Pricing of Cross-Sectional Idiosyncratic Volatility written by Bin Liu and published by . This book was released on 2015 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Han and Lesmond (2011) find that stock liquidity, namely bid-ask bounce, affects the pricing of idiosyncratic volatility. Following Ang et al. (2009) and Han and Lesmond (2011), we investigate the pricing of idiosyncratic volatility and liquidity-adjusted idiosyncratic volatility over the period January 2004 to December 2013 using a comprehensive Australian dataset. Our results indicate that (1) both lagged idiosyncratic volatility and lagged liquidity-adjusted idiosyncratic volatility are strongly and positively related to stock returns over the sample period; (2) consistent with Han and Lesmond (2011), the pricing of idiosyncratic volatility is largely captured by stock liquidity; (3) our liquidity adjusted idiosyncratic volatility estimates work well in explaining the variations of the stocks of small firms but do not explain much variations in stocks of large firms when size and BE/ME are controlled; (4) high idiosyncratic volatility stocks tend to be of small, volatile and illiquid.
Book Synopsis Idiosyncratic Volatility, Conditional Liquidity and Stock Returns by : Juliana Malagon
Download or read book Idiosyncratic Volatility, Conditional Liquidity and Stock Returns written by Juliana Malagon and published by . This book was released on 2016 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is strong evidence showing that stocks with higher levels of idiosyncratic risk provide relatively lower returns than stocks with lower levels of it. This paper points out that this negative idiosyncratic risk - expected returns relation is not pervasive over time, and provides a plausible explanation for its time-varying nature. Our results suggest that following recessions, the conditional pricing of liquidity creates a correction in prices of the high idiosyncratic volatility stocks that persists up to 10 months. As a result, the negative relation between idiosyncratic risk and expected returns is not observed following recessions.
Book Synopsis Idiosyncratic Volatility by : Tom Aabo
Download or read book Idiosyncratic Volatility written by Tom Aabo and published by . This book was released on 2016 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate the market efficiency implications of firm-specific return variation measured by absolute idiosyncratic volatility. We find that the absolute idiosyncratic volatility (the variance of the residual from an asset-pricing model) displays a positive and robust relationship to mispricing (based on both accounting information and alternatively abnormal stock returns). Thus, we find that larger values of absolute idiosyncratic volatility reflect an increasing role of noise traders. Previous literature has produced similar - or opposing - results. We deepen our understanding of the reasons for the lack of consensus in the previous literature by investigating the interaction between market volatility, idiosyncratic volatility, and R-squared. Thus, we show that 1) market volatility by itself is associated with mispricing, 2) absolute idiosyncratic volatility is associated with mispricing even when controlling for market volatility, 3) the strength of the association between absolute idiosyncratic volatility and mispricing depends on the level of market volatility, and 4) absolute and relative measures of idiosyncratic volatility have opposing associations with mispricing.
Book Synopsis Essays on Idiosyncratic Volatility and Asset Pricing by : Fatma Sonmez Saryal
Download or read book Essays on Idiosyncratic Volatility and Asset Pricing written by Fatma Sonmez Saryal and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, I study three aspects of idiosyncratic volatility. First, I examine the relation between idiosyncratic volatility and future stock returns. Next, I examine the share price effect and its interaction with the idiosyncratic volatility on stock returns. Finally, I examine the time series pattern of monthly aggregate monthly idiosyncratic volatility. In the first chapter, I examine the relation between idiosyncratic volatility and future stock returns. In their paper, Ang, Hodrick, Xing, and Zhang [AHXZ (2006)] show that idiosyncratic volatility is inversely related to future stock returns: low idiosyncratic volatility stocks earn higher returns than do high idiosyncratic volatility stocks. The main contribution of this paper is to provide evidence that it is the month to month changes in idiosyncratic volatility that produce AHXZ's results. More specifically, a portfolio of stocks that move from Quintile 1 (low idiosyncratic volatility) to Quintile 5 (high idiosyncratic volatility) earns an average risk-adjusted return of 5.64% per month in the month of the change. Whereas, a portfolio of stocks that move from the highest to the lowest idiosyncratic volatility quintiles earns -0.94% per month in the month of the change. Eliminating all firm-month observations with idiosyncratic volatility quintile changes, I find the opposite results to AHXZ: it is persistently low idiosyncratic volatility stocks that earn lower returns than do persistently high idiosyncratic volatility stocks. I find that many of the extreme changes in idiosyncratic volatility are related to business events. In general, the pattern usually observed is that an announcement or an event increases uncertainty about a stock and hence, its idiosyncratic volatility increases. After the event, uncertainty is resolved and the stock returns to a lower idiosyncratic volatility quintile. In the second chapter, I examine how the level of the share price interacts with idiosyncratic volatility to affect future stock returns. Ignoring transaction costs, a trading strategy that is long high-priced and short low-priced stocks earns positive abnormal returns with respect to the Fama-French (1992) three factor model. However, the observed positive abnormal returns are less significant if momentum is taken into account via the Carhart (1997) four factor model. Also the relation between idiosyncratic volatility and future stock returns differs for price sorted portfolios: it is negative for low and mid-priced stocks but positive for high-priced ones. These results are robust for low and-mid-priced stocks even after momentum is included. However, the positive relation for high-priced stocks disappears due to relatively large loadings on momentum for high idiosyncratic volatility stocks. I also show that skewness and momentum are significant determinants of idiosyncratic volatility for low-priced stocks and high-priced stocks respectively. One implication is that the importance of idiosyncratic volatility for future stock returns may in part be due its role as a disguised risk factor: either for momentum for high-priced stocks and skewness for low and mid-priced stocks. In the third chapter, I investigate the time series pattern of aggregate monthly idiosyncratic volatility. It has been shown that new riskier listings in the US stock markets are a reason for the increase in idiosyncratic volatility during the period 1963-2004. First, I show that this is more pronounced for Nasdaq new listings. Second, I show that for Nasdaq, prior to 1994 low-priced new listings became riskier, whereas during the internet bubble period it is the higher-priced listings that became riskier. Third, I show that institutional holdings have increased over time and have had a different impact on each new listing group: a negative for pre-1994 listings and a positive impact for post-1994 listings. Hence, I conclude that the observed time-series pattern of idiosyncratic volatility is a result of the changing nature of Nasdaq's investor clientele.
Book Synopsis Idiosyncratic Volatility and Stock Returns by : Kuntara Pukthuanthong
Download or read book Idiosyncratic Volatility and Stock Returns written by Kuntara Pukthuanthong and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Empirical evidences regarding the association of idiosyncratic volatility and stock returns are inconsistent with the capital asset pricing model (CAPM) which implies that idiosyncratic risk should not be priced because it would be fully eliminated through diversification. Using estimated-EGARCH conditional idiosyncratic volatility of individual stocks across 36 countries from 1973 to 2007, we find that idiosyncratic risk is priced on a significantly positive risk premium for stock returns. The evidence is statistically and economically significant. It overwhelmingly supports the prediction of existing theories that idiosyncratic risk is positively related to expected returns.
Book Synopsis Liquidity Biases and the Pricing of Cross-Sectional Idiosyncratic Volatility Around the World by : Yufeng Han
Download or read book Liquidity Biases and the Pricing of Cross-Sectional Idiosyncratic Volatility Around the World written by Yufeng Han and published by . This book was released on 2014 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines data from 45 world markets and shows that the previously documented relation between mean returns and idiosyncratic volatility arises because of biases in volatility estimates that we can attribute to the bid-ask bounce in trade prices. We show that no significant relation exists between mean returns and idiosyncratic volatility estimated from quote-midpoint returns. Further, there is no significant relation between mean returns and the portion of transaction-price based idiosyncratic volatility that is orthogonal to bid-ask spreads. The pricing of idiosyncratic volatility is due to the negative pricing of the bid-ask spread.
