Book excerpt: My dissertation focuses on economic studying of volatility issues. Three essays are contained in my dissertation. Essay 1 extends a microstructure model to explain the change of volatility and thus links traders' belief to the volatility change. Our model shows that when market is more uncertain about the value of the stock, the higher the (return) volatility. Essay 2 turns to explore more economic factors that could cause volatility regime switch. We find that US stock return processes, including drift, diffusion, and jump, differ along with US political cycle. Our results imply that the presidency in different parties has distinct policy making processes and thus influence the way information flows into the market, altering the return processes. In the final essay, we document and explain a volatility Bid-Ask spread pattern that increases as time to maturity decreases. Our research develops a model that explains the volatility spread pattern. We show that, as time passes, the required hedging uncertainty premium charged by the liquidity providers decays more slowly while the premium contained in the quoted options price decays at an increasingly higher rate which is determined by the option pricing model. Therefore, liquidity providers need to increase asking and decrease bidding volatility to maintain the profit necessary to compensate slowly decaying hedging uncertainty premium. Our results strongly suggest that studies on volatility spread should detrend the data to make the estimation models correct as well as the series stationary. Without adjusting the trend and autocorrelation problems, statistical results are inaccurate and misleading. More importantly, based on our theoretical model, we also find that: (a) the implied volatility spread does not increase in proportion to the increase of implied volatility, and (b) the increase of volatility uncertainty is not a sufficient condition for an increase in the percentage spread. Finally, to augment the validity of our claims, we provide rigorous econometric tests which support our propositions.

Book excerpt: This dissertation consists of three essays on stock market volatility. In the first essay, we show that investors will have the information in the idiosyncratic volatility spread when using two different models to estimate idiosyncratic volatility. In a theoretical framework, we show that idiosyncratic volatility spread is related to the change in beta and the new betas from the extra factors between two different factor models. Empirically, we find that idiosyncratic volatility spread predicts the cross section of stock returns. The negative spread-return relation is independent from the relation between idiosyncratic volatility and stock returns. The result is driven by the change in beta component and the new beta component of the spread. The spread-relation is also robust when investors estimate the spread using a conditional model or EGARCH method. In the second essay, the variance of stock returns is decomposed based on a conditional Fama-French three-factor model instead of its unconditional counterpart. Using time-varying alpha and betas in this model, it is evident that four additional risk terms must be considered. They include the variance of alpha, the variance of the interaction between the time-varying component of beta and factors, and two covariance terms. These additional risk terms are components that are included in the idiosyncratic risk estimate using an unconditional model. By investigating the relation between the risk terms and stock returns, we find that only the variance of the time-varying alpha is negatively associated with stock returns. Further tests show that stock returns are not affected by the variance of time-varying beta. These results are consistent with the findings in the literature identifying return predictability from time-varying alpha rather than betas. In the third essay, we employ a two-step estimation method to separate the upside and downside idiosyncratic volatility and examine its relation with future stock returns. We find that idiosyncratic volatility is negatively related to stock returns when the market is up and when it is down. The upside idiosyncratic volatility is not related to stock returns. Our results also suggest that the relation between downside idiosyncratic volatility and future stock returns is negative and significant. It is the downside idiosyncratic volatility that drives the inverse relation between total idiosyncratic volatility and stock returns. The results are consistent with the literature that investor overreact to bad news and underreact to good news.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation includes three essays on volatility and information content of futures markets. This work gives new insight into the structural changes in volatility, the information content of global interest rate futures, and the time-series behavior of the volatility term structure. The first essay examines structural volatility shifts U.S. crude oil and corn futures markets. In trying to capture the interrelations present in the two markets, we take seriously the importance of properly modelling smooth structural shifts. We incorporate trigonometric functions into a multivariate GARCH model of crude and corn futures prices to obtain the empirical volatility response functions and the time-varying correlation coefficient. Although both short-term and long-term futures exhibit shifts in the mean and volatility, volatility shifts do not manifest themselves in the same manner for different maturities. In the second essay, we investigate the term structure of interest rate futures in the US, Eurozone, United Kingdom, and Switzerland and empirically document five unique results. First, implied USD futures rates contain significantly different information compared to USD spot rates. Second, the four interest rate futures contracts contain similar information that is driven by one common component. Third, implied futures rates contain more information regarding future rate changes than return premiums. Fourth, information shifts are associated with macroeconomic conditions and central bank policies. Finally, significant information shifts occurred during the 2013-2015 time frame, which were greater than those of the great recessionary period of 2008-2009. The third essay focuses on the Samuelson hypothesis, a proposition that futures volatility declines with maturity. We study the strength of the Samuelson effect over time in ten most actively traded U.S. commodity futures. Capturing the dynamics of the futures volatility term structure with three factors, we show that in most markets the slope factor is strongly negative in certain periods and only weakly or not at all negative in other periods. Consistent with the linkage between carry arbitrage and the Samuelson hypothesis, we find that high inventory levels correspond to a flatter volatility term structure. We also find that a flatter volatility term structure corresponds to lower absolute futures term premiums.

Download or read book Three Essays on Idiosyncratic Volatility written by Anas Aboulamer and published by . This book was released on 2015 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of three essays. The first essay (chapter two) examines the relationship between idiosyncratic volatility and future returns in the Canadian market. The negative relationship between realized idiosyncratic volatility (RIvol) and future returns uncovered by Ang et al. (2006) for the US market has been attributed to return reversals. For the Canadian market where return reversals have considerably less importance, we find that RIvol is positively related to future returns, even after controlling for risk loadings, illiquidity and reversals. Unlike the findings of Bali et al. (2011) for the US market, we find for the Canadian market that the relationship between extreme positive returns and future returns is positive and that idiosyncratic volatility is consistently positively related to future returns. The second essay (chapter three) discusses the relationship between closed end fund discounts and the level of uncertainty about its holdings. Our trade-off model states that the intrinsic premium of a closed-end fund (CEF) is equal to the CEF’s price minus both its NAVPS (net asset value per share) and the net present value (NPV) of its future benefits from liquidity, managerial abilities and leverage minus its managerial costs. Any additional premium will persist to the extent that arbitrage between these two price series is both costly and risky. We find that arbitrage incompleteness due to the uncertainties about this NPV and the CEF’s holdings, as captured by idiosyncratic risk and other proxies, explains over two-thirds of the variation in CEF premiums or their changes. As expected, we find that the CEF premium is negatively related to gross leverage, management fees, cash and bond holdings, and positively related to liquidity enhancement, CEF performance and net leverage. These results are consistent with our finding that changes in CEF prices and NAVPS are more integrated than segmented using the Kappa test of Kapadia and Pu (2012). The third essay (chapter four) investigates the information content of idiosyncratic volatility around the public release of M&A rumors. We examine the releases of hand-collected initial rumors about potential M&A for 2250 firms. Unlike previous research, we find that a strategy of investing in firms with rumors of lower (greater) credibility yields negative (positive) changes in idiosyncratic volatilities around the rumor dates and subsequent returns. We argue that this asymmetric effect on idiosyncratic volatilities is linked to asymmetric changes in the heterogeneity of the probabilities of actual M&A when conditioned on rumor credibility. Changes in idiosyncratic volatilities are positively related to the market implicit probabilities of M&A as measured by the ratio of the market values at the M&A announcement and rumor dates.
