This book was released on 2008 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we model country-specific equity market return and association between country-specific equity market volatility and that of the world market in the downside and conventional asset pricing frameworks. For this a Factor- ARCH type process is adopted where world market risk (beta) is estimated in the mean equation and exposure of country-specific market volatility to world market volatility (volatility beta) is estimated in the variance equation. Generally, the beta is estimated higher for developed markets than for emerging markets and the reverse is observed in volatility beta. Even though the two types of betas are positive and significant, a cross-sectional analysis reveals that volatility beta is not priced. We observe these results when the analysis is carried out from an international investor perspective. When we repeat the analysis in sub-periods delineated via breakpoints in the world market return series and with alternative specifications of the variance equation our findings remain largely unchanged.

Available in PDF, EPUB and Kindle. Book excerpt: Previous studies have often found inconclusive evidence when explaining the beta risk-return relationship in the unconditional framework. This thesis analyses the unconditional and the conditional risk-return relationship on the Indonesian Stock Exchange (formerly Jakarta Stock Exchange) over the period 1996-2006. Both the conventional pricing framework and the downside pricing framework are employed to see which of the two may describe the behaviour of the Indonesian stock market better. As predicted, we found that the unconditional model fails to explain the risk-return cross-sectional relationship. In the conditional model based on market condition (up/down), this thesis finds a consistent and highly significant relationship between the CAPM beta and cross-sectional portfolios returns. In periods where excess market returns are negative, an inverse relationship between beta and portfolios returns exists. In periods where excess market returns are positive we find support for a positive risk-return relationship. Further, this thesis investigates whether the risk-return relation varies depending on the level of market volatility. Two market regimes based on the level of conditional volatility of market returns are specified - "low" and "high". The low and high volatility regimes are delineated with 3rd quartile, 90th percentile and median as the threshold parameters. In the low volatility regime the beta risk premium and downside beta risk premium are significantly different from zero. However, their signs are opposite to what is expected. In the models under the conventional framework skewness appears to be priced only in the up market and in the high volatility regime. However, when the market movement (up/down) and market volatility are incorporated as conditioning variables we found that the beta risk premium produces a significantly strong relationship with returns which is significantly positive in the up market and negative in the down market.
Book Synopsis Volatility Analysis and Asset Pricing of Stock Portfolios by : Klaus Grobys
Download or read book Volatility Analysis and Asset Pricing of Stock Portfolios written by Klaus Grobys and published by BoD – Books on Demand. This book was released on 2009 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since a vast number of investment funds are available at the market, it may be difficult for investors to figure out which fund might serve their needs the best. Especially in times where the uncertainty in the market increases, it might be even more important to figure out how investment funds response to such volatility shocks. Volatility as a risk measure may not be constant over time, but tight connected to the market risk in contrast. Hence, the exploration of the investment fund's volatility response to shocks in the stock market may give a deeper understanding of what the actual risk of an investor might be.

Available in PDF, EPUB and Kindle. Book excerpt: These implications are consistent with our empirical results. In the last part, we study the relationship between individual stock's volatility term structure and the stock's future return. We use a measure of stock's implied volatility term structure slope, defined as the difference between 3-month and 1-month implied volatility from at-the-money options, to demonstrate that option prices contain important information for the underlying equities. We show that option volatility term structure slopes are significant in explaining future equity returns in the cross-section. And we further find evidence that the implied volatility term structure is a measure of event risk: firms with the most negative volatility term structure are those for which the market anticipates news that may affect stock price within one month. Relevant events include, but are not limited to, earnings announcements.

This book was released on 1999-05 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a method to test the volatility predictions of the textbook asset-pricing exchange rate model, which imposes minimal structure on the data and does not commit to a choice of exchange rate “fundamentals.” Our method builds on existing tests of excess volatility in asset prices, combining them with a procedure that extracts unobservable fundamentals from survey-based exchange rate expectations. We apply our method to data for the three major exchange rates since 1984 and find broad evidence of excess exchange rate volatility with respect to the predictions of the canonical asset-pricing model in an efficient market.

Book excerpt: We investigate the relationship between consumption and the term structure using U.K. interest rate data. We demonstrate that the term structure contains information about future economic activity as implied by the benchmark time separable power utility consumption based capital asset pricing model (C-CAPM) since the yield spread has forecasting power for future consumption growth. Further, we analyze the ability of this benchmark and two alternative models which adopt utility functions characterized by non-separability, namely, the extension to the habit formation model of Campbell and Cochrane (1999) proposed by Wachter (2006) and the housing C-CAPM proposed by Piazzesi et al. (2007). Our findings are supportive of the habit formation specification of Wachter (2006), other models fail to yield economically plausible parameter values.

Book excerpt: My dissertation is developed to address unresolved issues in the asset pricing literature, focusing on both risk premium levels and dynamics. Chapter 1 addresses short-horizon risk premium dynamics. In the data, stock market volatility weakly or even negatively predicts short-run equity and variance risk premia, challenging positive risk-return trade-offs at the heart of leading asset pricing models. I show that a puzzling negative volatility-risk premia relationship concentrates in scattered high-uncertainty states, which occur about 20\% of the time. While at other times, the relationship is strongly positive. I develop a micro-founded learning model in which due to learning frictions investors underreact to structural breaks in high-volatility periods and overreact to transitory variance shocks in normal times. The model can successfully explain the novel time-varying volatility-risk premia relationship at short and long horizons. The model can further account for many other data features, such as a robust positive correlation between equity and variance risk premium, the leverage effect, and negative observations of equity and variance risk premia at the onsets of recessions. Chapter 2, coauthored with Professor Bjorn Eraker, focuse on equilibrium derivatives pricing. It is motivated by the observation that leading asset pricing models typically can not explain the levels or dynamics of VIX options prices. We develop a tractable equilibrium pricing model to explain observed characteristics in equity returns, VIX futures, S\&P 500 options, and VIX options data based on affine jump-diffusive state dynamics and representative agents endowed with Duffie-Epstein recursive preferences. A specific model aimed at capturing VIX options prices and other asset market data is shown to successfully replicate the salient features of consumption, dividends, and asset market data, including the first two moments of VIX futures returns, the average implied volatilities in SPX and VIX options, and first and higher-order moments of VIX options returns. In the data, we document a time variation in the shape of VIX option implied volatility and a time-varying hedging relationship between VIX and SPX options which our model both captures. Our model also matches many other asset pricing moments such as equity premia, variance risk premia, risk-free interest rates, and short-horizon return predictability. To derive our specific model, we first develop a general framework for pricing assets under recursive Duffie-Epstein preferences with IES set to one under the assumption that state variables follow affine jump diffusions, as in \citet{DPS00}. Relative to the literature, our framework has a clear marginal contribution that it is an endowment-based equilibrium model with (i) clearly stated affine state variable dynamics and (ii) precisely characterized equilibrium value function, risk-free rate, prices of risks, and risk-neutral state dynamics. We prove our state-price density is a precise $IES\to1$ limit of that approximately solved in \citet{ErakShal08}. The recursive preference assumption implies that higher-order conditional moments of the economic fundamental, such as its growth volatility and volatility-of-volatility, are explicitly priced in equilibrium. Since VIX derivatives depend on these factors, this in turn implies that the former carry non-zero risk premia.
Book Synopsis Asset Pricing with Idiosyncratic Risk and Overlapping Generations by : Kjetil Storesletten
Download or read book Asset Pricing with Idiosyncratic Risk and Overlapping Generations written by Kjetil Storesletten and published by . This book was released on 2011 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of existing studies have concluded that risk sharing allocations supported by competitive, incomplete markets equilibria are quantitatively close to first-best. Equilibrium asset prices in these models have been difficult to distinguish from those associated with a complete markets model, the counterfactual features of which have been widely documented. This paper asks if life cycle considerations, in conjunction with persistent idiosyncratic shocks which become more volatile during aggregate downturns, can reconcile the quantitative properties of the competitive asset pricing framework with those of observed asset returns. We begin by arguing that data from the Panel Study on Income Dynamics support the plausibility of such a shock process. Our estimates suggest a high degree of persistence as well as a substantial increase in idiosyncratic conditional volatility coincident with periods of low growth in U.S. GNP. When these factors are incorporated in a stationary overlapping generations framework, the implications for the returns on risky assets are substantial. Plausible parameterizations of our economy are able to generate Sharpe ratios which match those observed in U.S. data. Our economy cannot, however, account for the level of variability of stock returns, owing in large part to the specification of its production technology.

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 Conditional Asset Pricing - Predicting Time Varying Beta-Factors with Group Method of Data Handling Methods by : Sebastian Schneider
Download or read book Conditional Asset Pricing - Predicting Time Varying Beta-Factors with Group Method of Data Handling Methods written by Sebastian Schneider and published by . This book was released on 2005 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Allowing for time-varying risk premia yields sophisticated asset pricing models, but the search for adequate model specifications is more challenging. We introduce, to our knowledge, previously in conditional asset pricing not used Group Method of Data Handling (GMDH) that rests on sorting out requiring statsitical models for complex problems of unknown structure but does not require a model to predict conditional variation in betas. We find that lagged instruments used to proxy for expected returns in conditional asset pricing provide a challenge not only for the unconditional CAPM but also the Fama-French-model. Thereby non-linear GMDH-algorithms challenge traditional models of conditional asset pricing as we find a highly non-linear influence of lagged instruments on both conditional alphas and betas. Therefore, predetermining a structure for functional relationships between conditional alphas as well as betas and lagged instruments may lead to a significant misspecification of asset pricing models.
Book Synopsis Is Consumption Growth Only a Sideshow in Asset Pricing? by : Thomas A. Maurer
Download or read book Is Consumption Growth Only a Sideshow in Asset Pricing? written by Thomas A. Maurer and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I show that risk sources such as unexpected demographic changes or shocks to the agent's subjective time preferences may have stronger implications and be of greater importance for asset pricing than risk in the (aggregate) consumption growth process. In the first chapter, I discuss stochastic changes to time preferences. Shocks to the agent's subjective time discounting of future utility cause stochastic changes in asset prices and the agent's value function. Independent of the consumption growth process, shocks to time discounting imply a covariation between asset returns and the marginal utility process, and the equity premium is non-zero. My model can generate both a reasonably low level and volatility in the risk-free real interest rate and a high stock price volatility and equity premium. If time discounting follows a process with mean- reversion, then the interest rate process is mean-reverting and stock returns are (at long horizons) negatively auto-correlated. In the second chapter, I analyze the asset pricing implications of birth and death rate shocks in an overlapping generations model. The interest rate and the equity premium are time varying and under certain conditions the interest rate is lower and the equity premium is higher during periods characterized by a high birth rate and low mortality than in times of a low birth rate and high mortality. Demographic changes may explain substantial parts of the time variation in the real interest rate and the equity premium. Demographic uncertainty implies a large unconditional variation in asset returns and leads to stochastic changes in the conditional volatility of stock returns. In the last chapter, I illustrate how shocks to the death rate may affect expected asset returns in the cross-section. An agent demands more of an asset with higher (lower) payoff in states of the world when he expects to live longer (shorter) and marginal utility is high (low) than an asset with the opposite payoff schedule. In equilibrium, the first asset pays a lower expected return than the latter. Empirical evidence supports the model. Out-of-sample evidence suggests that a strategy, which loads on uncertainty in the death rate, pays a positive unexplained return according to traditional market models.

Download or read book A Dynamic Test of Conditional Asset Pricing Models written by Daniele Bianchi and published by . This book was released on 2019 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: I use Bayesian tools to develop a dynamic testing methodology for conditional factor pricing models, in which time-varying betas, idiosyncratic risks, and factors risk premia are jointly estimated in a single step. Based on this framework, I test over fifty years of post-war monthly data some of the most common factor pricing models on size, book-to-market, and momentum deciles portfolios, both in the time series and in the cross section. The empirical results show that, a conditional specification of the recent five-factor model of Fama and French (2015) outperforms a set of theory-based competing linear pricing models along several dimensions.
