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.

This book was released on 2009 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock prices are very volatile. Their fundamental value as measured by the ex-post realized net present value of dividends fluctuates far less than the stock price itself. A hot debate about the efficiency of stock markets has arisen from this observation. Many researchers attribute at least some of this "excess volatility" we observe in stock prices to inefficient actions of economic agents. This dissertation is about the macroeconomic consequences of excess volatility in stock prices. It demonstrates that this volatility can lead to large reductions in welfare for households and discusses ways for governmental intervention to alleviate adverse effects. The dissertation furthermore shows that large stock market volatility can arise from tiny, in fact arbitrarily small, errors in agents' actions or in their belief formation.

Available in PDF, EPUB and Kindle. Book excerpt: Essay 3 investigates the relation between proxies for investor sentiment and stock market crises and recoveries on international indices. Using an Early-Warning-System (EWS) model, the essay examines whether investor sentiment is a useful predictor for the occurrence of stock market crises and early signs of recovery. Three alternative proxies are used to measure investor sentiment, including previously cited measures of stock market riskiness, investors' risk aversion and investors' optimism about stock markets. The results show that investor sentiment is overall a significant predictor of the occurrence of crises within a one year period, and that the addition of sentiment into early warning signal models of stock market crises can improve the predictive performance of the model (increases in investor sentiment increase the probability of occurrence of a crisis, which is in line with previous contributions finding a negative lead-lag relation between sentiment and stock returns). The extension of the model to early signs of recoveries also shows that sentiment is a reliable predictor. The measure of stock market riskiness (Baker and Wurgler, 2006) is found to be a better predictor than the Volatility Index (VIX) and the Put-to-Call Ratio (PCR). The cross-country comparison results confirms the literature findings that the link between sentiment and stock market returns varies across indices and cultures, as the predictive power of the variable appears strongest in the French and U.S. indices.

Book excerpt: This dissertation is composed of three essays. The first essay investigates the information content of the limit order book (LOB) on the Shanghai Stock Exchange (SHSE), a purely order-driven market, for predicting future stock price volatility. We find that the LOB supply schedule consistently and significantly predicts the future price volatility. But this predictive power of LOB declines during the extreme market wide movements. We also find that buy orders are more informative over future price volatility than sell orders but sell (buy) orders becomes more informative during the extreme market wide down (up) movement days. Finally, we document that predictive power of LOB is short lived and markets are efficient over the longer time horizon. The second essay examines the effect of high frequency trading on market quality, systemic risk and trading strategies. In 2010 the Tokyo Stock Exchange, the largest exchange headquartered outside the US, introduced a new trading platform, Arrowhead, which reduced latency by 99.97% and increased co-located high-frequency trading from zero to 36% of volume. Arrowhead improved market liquidity and reduced volatility, but it also amplified systematic risks factors like quotes to trade ratio, order-flow autocorrelation and cross correlation, and tail risks. Arrowhead also affected trading strategies by increasing trade price predictability and the use of fleeting orders. Cost of immediacy serves as a channel through which reduced latency affects market quality, systematic risks, and trading outcome. The third essay analyzes the links between corporate finance policies and investment clienteles by comparing the cross-sectional variation in the dividend payout policies of companies across 32 countries. Beyond the impact of firm-specific accounting and financial variables, this study investigates how the country level variations: shareholder demand due to demographic variations and consumption needs, agency problems manifested in the extent of minority shareholder protection and business disclosures, and market quality in terms of transparency and liquidity; affect dividend payout policies. We find that firms have generous dividend payout policies when diverse shareholder demands are strong, extents of business disclosures and legal protections are weak, and the market qualities are poor. The empirical evidence supports the presence of strong dividend clienteles in a global setting. .

Book excerpt: This dissertation consists of three essays that address recent topics in financial markets that concern for scholars, policymakers, and investors. The first essay examines the benefits of international diversification for US investors, while accounting for market development, corporate governance, market cap effects, and structural change across countries over period August 1996 -July 2013. Improved risk adjusted returns are obtained from a diversified portfolio consisting of a mix of developed and emerging countries. Additionally, we find that diversification benefits are not significant for most of the small-cap foreign assets when an investor already holds position in corresponding countries large-cap assets. Diversification benefits based on the governance effectiveness of a country's companies are not ubiquitous. We find that economically significant improvements in risk-return performance can be attained by adding large caps of developed countries with high and low overall Governance Metrics International (GMI) ratings and large and small caps of emerging countries with low overall GMI ratings to the investment universe containing the assets of common law developed countries. However, diversification benefits are economically significant only for large and small caps of low GMI emerging countries when short selling is not allowed. The second essay looks at the market impact of recent regulatory changes in Canada that provide for trading halts on individual stocks that experience large upside or downside movements. The focus is on all stocks traded on the Toronto Stock Exchange since the inception of the single stock circuit breaker rule (SSCB) in February 2012, to replace the short-sale uptick rule. The results support pricing efficiency: material information that caused the circuit breaker is incorporated in stock prices on the day of the halt (neither overreaction nor underreaction), with no decline in market liquidity. Using trade-by-trade data constructed on 5-minute trading intervals, we refine the daily results, and show that shocks in realized volatility are focused in the ten-minute trading interval surrounding the halts. While circuit breakers provide a limited "safety net" for investors when their stocks are subject to severe volatility, they do not provide for a quick turnaround for stocks experiencing severe price decline events. The last essay re-examines the historical vs implied volatility spread anomaly, reported by Goyal and Saretto (2009) using a second-order stochastic dominance (SSD) criterion. The approach incorporates transaction frictions, and is robust to model specification problems, return distributions, as well as preferences. It is found that option trading frictions such as cash collateral requirements and option trading costs significantly reduce but do not eliminate returns to a long-short straddle trading strategy pre-2006 period. However, the anomaly disappears after 2006, consistent with market efficiency. The SSD test results confirm the findings.

Book excerpt: "This thesis consists of three essays in empirical asset pricing. In the first essay, I study momentum crashes in emerging equity markets. In particular, I investigate that the momentum crashes are related to volatility, unconditional of the market state. I use emerging stock markets as a laboratory because of their high volatility in both bear and bull markets. My main finding is that momentum crashes are not limited to bear markets, and in fact, one third are experienced in bull markets. These crashes do not fit into the optionality model of Daniel and Moskowitz (2016). Instead, I provide evidence that momentum crashes are linked to the market volatility. In volatile states, the optionality payoff of momentum increases and momentum skewness decreases. Furthermore, I show that the poor performance of momentum in EMs is due to the high volatility in these markets. In the second essay, I investigate whether excessive shortselling is the primary cause for momentum crashes. My hypothesis is that the excessive shortselling of the loser stocks pushes their price below their fundamental values. When the market rebounds, the reversal in the price of the losers leads to momentum crash. I collect the data on shortselling policies across countries, and test whether momentum crashes less in markets with shortselling ban, controlling for the market state and volatility. My results show that the crashes are less severe in markets with shortselling ban, suggesting that shortselling partially explains momentum crashes.In the third essay, I study the mutual fund industry in 77 countries and examine how the fund styles are developed on the aggregate level. I apply textual analysis to the fund names in order to classify funds. I find that the 20 most frequently used words appear in over 50% of all fund names and I define 10 categories (“styles”) based on those (and related) words. These 10 categories are sufficient to classify over 85% of all funds. I find that the menu of funds are remarkably universal. My main result shows how the menu of funds offered to investors in those 77 countries converges over time to a common (“global”) menu of funds. I trace this surprisingly simple and uniform process of global menu convergence to the actions of individual fund families who follow similar growth paths. My results shed new light on the aggregate process of financial innovation and the industrial organization of the asset management industry that appears to produce the same “wholesale” menu around the world"--

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.

Available in PDF, EPUB and Kindle. Book excerpt: The central objective of my dissertation is to study the behavior of firm-specific volatility in countries around the world. Consistent with existing literature, I use firm-specific volatility to measure two important concepts: the information content of stocks and firm-specific risk. In Chapter One I hypothesize that the institutional environment in a country has direct consequences on firm-specific risk. A stronger institutional environment results in higher product market competition, higher firm turnover, and higher rates of technological innovation. Consistent with my predictions, I find that creative destruction explains a significant proportion of the cross-sectional differences in firm specific volatility in 40 countries. In Chapter Two I look at the cyclical fluctuations of comovement in the US and 27 other countries during the period 1980-2005. I find that, in general, comovement tends to be countercyclical. Additionally, I find wide cross-sectional variation in the strength of association between comovement and the business cycle. This strength of association positively correlates to a measure of variability in information production. In turn, I find that the information environment can reduce variability in information production and reduce cyclical fluctuations in stock return correlations. Finally, in Chapter I find that idiosyncratic risk has explanatory power on the cross-section of expected returns in international markets. I find strong support to the theory in all countries under study. In eight of the fifteen countries surveyed the relation is significantly positive while in the remaining seven countries the relation is zero. In no instance do I find the relation to be negative. In addition, the results from my analysis are economically significant. I find that after controlling for stock characteristics (beta, size, and momentum) the response in excess returns to a 1% increase in monthly-expected idiosyncratic risk ranges across countries between zero and one half of a percent.
