Available in PDF, EPUB and Kindle. Book excerpt: Recent empirical evidence has shown that the relationship between idiosyncratic volatility and a stock's expected return depends on the pricing of the stock: it is negative among overvalued stocks and positive among undervalued ones. We provide both theoretical and numerical evidence that this risk-return relationship might be driven purely by mathematical properties of return distributions. Using a simulation-based approach, we document that even in completely random samples, the correlation between idiosyncratic risk and mean returns depends on the ex-post estimation of abnormal returns.

Book excerpt: The finding that stocks with high idiosyncratic volatility tend to have low future returns has been dubbed an empirical anomaly in the finance literature. We seek to understand this puzzle by separating the upside volatility associated with positive idiosyncratic returns from the downside risk associated with negative idiosyncratic returns. We find that downside risk is not inversely related to future stock returns, thus easing the concern that the empirical anomaly is a mispricing of risk. Rather, our results suggest that it is upside volatility that drives the inverse idiosyncratic volatility and return relation. We further examine whether the relation of future returns with downside and upside volatility accords with investor underreaction to bad news and overreaction to good news. Finally, we show that momentum strategies may be enhanced by taking into account stocks' upside volatility.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, I explore the impact of idiosyncratic risk on asset returns. The first essay examines how idiosyncratic risk affects the cross-section of stock returns. I use an exponential GARCH model to forecast expected idiosyncratic volatility and employ a combination of the size effect, value premium, return momentum and short-term reversal to measure relative mispricing. I find that stock returns monotonically increase in idiosyncratic risk for relatively undervalued stocks and monotonically decrease in idiosyncratic risk for relatively overvalued stocks. This phenomenon is robust to various subsamples and industries, and cannot be explained by risk factors or firm characteristics. Further, transaction costs, short-sale constraints and information uncertainty cannot account for the role of idiosyncratic risk. Overall, these findings are consistent with the limits of arbitrage arguments and demonstrate the importance of idiosyncratic risk as an arbitrage cost. The second essay studies the cross-sectional determinants of delta-hedged stock option returns with an emphasis on the pricing of volatility risk. We find that the average delta-hedged option returns are significantly negative for most stocks, and they decrease monotonically with both total and idiosyncratic volatility of the underlying stock. Our results are robust and cannot be explained by the Fama-French factors, market volatility risk, jump risk, or the effect of past stock return and volatility-related option mispricing. Our results strongly support a negative market price of volatility risk specification that is proportional to the volatility level. Reflecting this volatility risk premium, writing covered calls on high volatility stocks on average earns about 2% more per month than selling covered calls on low volatility stocks. This spread is higher when it is more difficult to arbitrage between stock and option.

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.

Download or read book The Information Content of Idiosyncratic Volatility written by George J. Jiang and published by . This book was released on 2012 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper uses adverse selection in corporate information disclosure to explain a recently documented asset pricing anomaly. Ang, Hodrick, Xing, and Zhang (2006a) show that stocks with high idiosyncratic return volatilities tend to have low future returns. In this paper, we find that idiosyncratic volatility is also inversely related to future earning shocks. More importantly, we show that the return predictive power of idiosyncratic volatility is induced by its information content on future earnings. We provide empirical results to support our explanation that firms with poor prospect of future earnings tend to disclose less information, resulting in a higher degree of heterogeneity in investors beliefs, which in turn leads to higher stock return volatility and trading volume. Further analysis suggests that investors tend to underreact to earnings information in idiosyncratic volatility, and the mispricing of idiosyncratic volatility is inversely related to both investor sophistication and stock liquidity.

This book was released on 2018-02-21 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2017 in the subject Business economics - Investment and Finance, grade: 1,7, University of Mannheim, language: English, abstract: The foundation of this contribution will be the verification of the empirical results presented by Liu et al. (2017). We will start by summarizing their findings and explanations in Chapter 2 (Theoretical Background) and build the theoretical foundation upon which the empirical interpretation will rest. We actually view the compilation of the theoretical explanations in an intuitive line of reasoning as our first valuable contribution for our readers, as an understanding of the topic is not as easily to grasp after a first consultation of the papers. In Chapter 3 (Empirical Results) we address the actual calculations and most important summary statistics that will either speak in support or against our interpretations. In 3.1 (Data and Methodology), we present our dataset important technical notes and in Chapter 3.2 (The Beta Anomaly) we summarize and try to replicate the empirical findings of Liu et al. (2017), which will serve as the bedrock of interpretations we will arrive at in following pages. In Chapter 3.3 (Betting-against-Correlation) and its sub-sections on leverage, size and sentiment, we turn our attention to a paper by Asness et al. (2017) which contributed and responded to the findings of Liu et al. (2017), but with often diametrically contradicting views. The reference date of 2017 suggests that both papers belong to a highly new set of research and we believe that by covering those two and adding our own findings we can add significant clarity to actually understand what is going in the space of the beta anomaly. In Chapter 3.4 (BAB vs. BAI), we finalise the empirical analysis by contrasting opposing views on strategies that are designed to exploit the low-beta anomaly and realign the findings that we came across. We will summarize the newly gained insights for our readers in our last Chapter 4.

Available in PDF, EPUB and Kindle. Book excerpt: Liquidity and Asset Prices reviews the literature that studies the relationship between liquidity and asset prices. The authors review the theoretical literature that predicts how liquidity affects a security's required return and discuss the empirical connection between the two. Liquidity and Asset Prices surveys the theory of liquidity-based asset pricing followed by the empirical evidence. The theory section proceeds from basic models with exogenous holding periods to those that incorporate additional elements of risk and endogenous holding periods. The empirical section reviews the evidence on the liquidity premium for stocks, bonds, and other financial assets.

Download or read book Idiosyncratic Risk Costly Arbitrage and the Cross Section of Stock Returns written by Jie Cao and published by . This book was released on 2016 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: We test a new cross-sectional relation between expected stock return and idiosyncratic risk implied by the theory of costly arbitrage. If arbitrageurs find it more difficult to correct the mispricing of stocks with high idiosyncratic risk, there should be a positive (negative) relation between expected return and idiosyncratic risk for undervalued (overvalued) stocks. We combine several well-known anomalies to measure stock mispricing and proxy stock idiosyncratic risk using an exponential GARCH model for stock returns. We confirm that average stock returns monotonically increase (decrease) with idiosyncratic risk for undervalued (overvalued) stocks. Overall, our results support the importance of idiosyncratic risk as an arbitrage cost.

Download or read book Cross Section of Option Returns and Idiosyncratic Stock Volatility written by Jie Cao and published by . This book was released on 2016 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper documents a robust new finding that delta-hedged equity option return decreases monotonically with an increase in the idiosyncratic volatility of the underlying stock. This result can not be explained by standard risk factors. It is distinct from existing anomalies in the stock market or volatility-related option mispricing. It is consistent with market imperfections and constrained financial intermediaries. Dealers charge a higher premium for options on high idiosyncratic volatility stocks due to their higher arbitrage costs. Controlling for limits to arbitrage proxies reduces the strength of the negative relation between delta-hedged option return and idiosyncratic volatility by about 40%.

Download or read book The Systematic Risk of Idiosyncratic Volatility written by Jefferson Duarte and published by . This book was released on 2014 with total page 45 pages. 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.

Download or read book Arbitrage Risk and Investor Sentiment as Causes of Persistent Mispricing written by Massimo Guidolin and published by . This book was released on 2018 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate the relationship between risk-adjusted returns, arbitrage risk and arbitrage asymmetry, and investor sentiment in the European stock market. Under the assumption that idiosyncratic volatility (IVOL) causes arbitrage risk, we analyze the effects of IVOL on the-abnormal returns of the Euro Stoxx 50 large cap constituents. After classifying the stocks in two mispricing categories, we uncover evidence of arbitrage risk especially in the overpriced group: the highest IVOL overpriced portfolio is the most overpriced, which implies persistent subsequent risk-adjusted returns that slowly revert to zero. When the estimation is performed afresh separating the high- from the low-sentiment periods and controlling for macroeconomic conditions, we find evidence of a negative relation between investor sentiment and IVOL effects, which is yet more pronounced for the highest arbitrage-risk stocks, which is consistent with pure, psychological biases strongly affecting the impact of arbitrage risk on the speed of correction of mispricing.

Download or read book Arbitrage Asymmetry and the Idiosyncratic Volatility Puzzle written by Robert F. Stambaugh and published by . This book was released on 2020 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many investors purchase stock but are reluctant or unable to sell short. Combining this arbitrage asymmetry with the arbitrage risk represented by idiosyncratic volatility (IVOL) explains the negative relation between IVOL and average return. The IVOL-return relation is negative among overpriced stocks but positive among underpriced stocks, with mispricing determined by combining 11 return anomalies. Consistent with arbitrage asymmetry, the negative relation among overpriced stocks is stronger, especially for stocks less easily shorted, so the overall IVOL-return relation is negative. Further supporting our explanation, high investor sentiment weakens the positive relation among underpriced stocks and, especially, strengthens the negative relation among overpriced stocks.

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.

Download or read book Idiosyncratic Risk Long Term Reversal and Momentum written by R. David McLean and published by . This book was released on 2009 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: I test whether the persistence of the momentum and reversal effects is the result of idiosyncratic risk limiting arbitrage. Idiosyncratic deters arbitrage, regardless of the arbitrageur's level of diversification. Reversal is prevalent only in high idiosyncratic risk stocks, suggesting that idiosyncratic risk limits arbitrage in reversal mispricing. This finding is robust to controls for transaction costs, informed trading, and systematic relations between idiosyncratic risk and subsequent returns. Momentum is not related to idiosyncratic risk. Momentum generates a smaller aggregate return than reversal, so the findings along with those in related studies suggest that transaction costs are sufficient to prevent arbitrageurs from eliminating momentum mispricing.

Download or read book Idiosyncratic Volatility and the Cross Section of Expected Returns written by Turan G. Bali and published by . This book was released on 2012 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the cross-sectional relation between idiosyncratic volatility and expected stock returns. The results indicate that (i) data frequency used to estimate idiosyncratic volatility, (ii) weighting scheme used to compute average portfolio returns, (iii) breakpoints utilized to sort stocks into quintile portfolios, and (iv) using a screen for size, price and liquidity play a critical role in determining the existence and significance of a relation between idiosyncratic risk and the cross-section of expected returns. Portfolio-level analyses based on two different measures of idiosyncratic volatility (estimated using daily and monthly data), three weighting schemes (value-weighted, equal-weighted, inverse-volatility-weighted), three breakpoints (CRSP, NYSE, equal-market-share), and two different samples (NYSE/AMEX/NASDAQ and NYSE) indicate that there is no robust, significant relation between idiosyncratic volatility and expected returns.
