Download or read book A Dynamic Asset Pricing Model with Time-Varying Idiosyncratic Risk written by Paskalis Glabadanidis and published by . This book was released on 2004 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper utilizes a state-of-the-art multivariate GARCH model to account for time-variation in idiosyncratic risk in improving the performance of the single-factor CAPM, the three factor Fama-French model and the four-factor Carhart model. I show how to incorporate time-variation in the second moments of the residuals in a very general way. When applied to the Fama and French (1993) size/book-to-market portfolio returns, I document a 50% reduction in the average absolute pricing error of this dynamic Fama-French model over the static one. In addition, I find that market betas of growth stocks increase during recessions while market betas of value stocks decrease during recessions and that HML betas of value stocks increase during recessions while HML betas of growth stocks decrease during recessions. Finally, for the Fama and French industry portfolios I find that the single-factor model outperforms the three and four factor models substantially both in their unconditional and conditional forms.
Book Synopsis A Dynamic Test of Conditional Asset Pricing Models by : Daniele Bianchi
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.

Book Synopsis Multi-moment Asset Allocation and Pricing Models by : Emmanuel Jurczenko
Download or read book Multi-moment Asset Allocation and Pricing Models written by Emmanuel Jurczenko and published by Wiley. This book was released on 2006-10-02 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: While mainstream financial theories and applications assume that asset returns are normally distributed and individual preferences are quadratic, the overwhelming empirical evidence shows otherwise. Indeed, most of the asset returns exhibit “fat-tails” distributions and investors exhibit asymmetric preferences. These empirical findings lead to the development of a new area of research dedicated to the introduction of higher order moments in portfolio theory and asset pricing models. Multi-moment asset pricing is a revolutionary new way of modeling time series in finance which allows various degrees of long-term memory to be generated. It allows risk and prices of risk to vary through time enabling the accurate valuation of long-lived assets. This book presents the state-of-the art in multi-moment asset allocation and pricing models and provides many new developments in a single volume, collecting in a unified framework theoretical results and applications previously scattered throughout the financial literature. The topics covered in this comprehensive volume include: four-moment individual risk preferences, mathematics of the multi-moment efficient frontier, coherent asymmetric risks measures, hedge funds asset allocation under higher moments, time-varying specifications of (co)moments and multi-moment asset pricing models with homogeneous and heterogeneous agents. Written by leading academics, Multi-moment Asset Allocation and Pricing Models offers a unique opportunity to explore the latest findings in this new field of research.

Book Synopsis A New Model of Capital Asset Prices by : James W. Kolari
Download or read book A New Model of Capital Asset Prices written by James W. Kolari and published by Springer Nature. This book was released on 2021-03-01 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes a new capital asset pricing model dubbed the ZCAPM that outperforms other popular models in empirical tests using US stock returns. The ZCAPM is derived from Fischer Black’s well-known zero-beta CAPM, itself a more general form of the famous capital asset pricing model (CAPM) by 1990 Nobel Laureate William Sharpe and others. It is widely accepted that the CAPM has failed in its theoretical relation between market beta risk and average stock returns, as numerous studies have shown that it does not work in the real world with empirical stock return data. The upshot of the CAPM’s failure is that many new factors have been proposed by researchers. However, the number of factors proposed by authors has steadily increased into the hundreds over the past three decades. This new ZCAPM is a path-breaking asset pricing model that is shown to outperform popular models currently in practice in finance across different test assets and time periods. Since asset pricing is central to the field of finance, it can be broadly employed across many areas, including investment analysis, cost of equity analyses, valuation, corporate decision making, pension portfolio management, etc. The ZCAPM represents a revolution in finance that proves the CAPM as conceived by Sharpe and others is alive and well in a new form, and will certainly be of interest to academics, researchers, students, and professionals of finance, investing, and economics.

Book Synopsis Time-Varying Asset Pricing Models in the Context of Segmented Markets by : Chris Bilson
Download or read book Time-Varying Asset Pricing Models in the Context of Segmented Markets written by Chris Bilson and published by . This book was released on 2002 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores and tests two multi-factor asset pricing models in an international context. One model focuses only on local risk factors and therefore assumes that the market is completely segmented. The other model focuses only on global risk factors and assumes that the market is fully integrated. The models incorporate time-variation in both the risk exposures and risk premia. The models are applied in cross-section to a range of developed and emerging markets so that varying levels of integration are examined. Expected returns are formed using time-varying estimates of risk premia that allow for out-of-sample testing. Using a range of performance metrics, the findings show that returns in developed markets are better approximated by a global pricing model, whereas returns in emerging markets are better represented by a local pricing model. These results are found to be generally robust to a range of research design issues.
Book Synopsis Time-Varying Conditional Covariances in Tests of Asset Pricing Models by : Campbell R. Harvey
Download or read book Time-Varying Conditional Covariances in Tests of Asset Pricing Models written by Campbell R. Harvey and published by . This book was released on 2005 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposes tests of asset pricing models that allow for time variation in conditional covariances. The evidence indicates that the conditional covariances do change through time. Estimates of the expected excess return on the market divided by the variance of the market (reward-to-risk ratio) are presented for the Sharpe-Lintner CAPM, as well as a number of tests of the model specification. The patterns of the pricing errors through time suggest the model's inability to capture the dynamic behavior of asset returns. This is the working paper version of my 1989 Journal of Financial Economics article.
Book Synopsis Tests of Asset Pricing with Time-Varying Factor Loads by : Antonio F. Galvao
Download or read book Tests of Asset Pricing with Time-Varying Factor Loads written by Antonio F. Galvao and published by . This book was released on 2017 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposes an empirical asset pricing test based on the homogeneity of the factor risk premia across risky assets. Factor loadings are considered to be dynamic and estimated from data at higher frequencies. The factor risk premia are obtained as estimates from time series regressions applied to each risky asset. We propose Swamy-type tests robust to the presence of generated regressors to assess the homogeneity of the factor risk premia. An application to US industry portfolios confirms multifactor asset pricing specifications for data up to September 2008, however, the models are rejected if the post-September 2008 period is included in the analysis.
Book Synopsis International Asset Pricing and Time-Varying Risk Premia by : Devraj Basu
Download or read book International Asset Pricing and Time-Varying Risk Premia written by Devraj Basu and published by . This book was released on 2019 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper introduces an international asset pricing model with time-varying risk premia. It augments the two factor model which has the return on the world index and trade weighted exchange rates as factors, with skewness and kurtosis factors. This leads to a stochastic discount factor that is non-linear and has time-varying factor loadings that are functions of global variables. We test this model on market indices, size and momentum sorted portfolios that are formed from stocks listed in G8 countries, as well as country-neutral size, book-to-market and momentum portfolios. Overall, the model is capable of pricing almost all sets of base assets unconditionally using only global predictive variables. It also explains much of the cross sectional variation of the country, size and momentum portfolios, and also achieves much of the substantial size and momentum premiums. The role of time-varying risk premiums that are functions of global variables is crucial to the performance of the model, particularly in the case of the exchange rate factor.
Download or read book Asset Pricing written by Bing Cheng and published by World Scientific. This book was released on 2008 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern asset pricing models play a central role in finance and economic theory and applications. This book introduces a structural theory to evaluate these asset pricing models and throws light on the existence of Equity Premium Puzzle. Based on the structural theory, some algebraic (valuation-preserving) operations are developed in asset spaces and pricing kernel spaces. This has a very important implication leading to practical guidance in portfolio management and asset allocation in the global financial industry. The book also covers topics, such as the role of over-confidence in asset pricing modeling, relationship of the portfolio insurance with option and consumption-based asset pricing models, etc.
Book Synopsis Dynamic Asset Pricing Theory by : Darrell Duffie
Download or read book Dynamic Asset Pricing Theory written by Darrell Duffie and published by Princeton University Press. This book was released on 2010-01-27 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a thoroughly updated edition of Dynamic Asset Pricing Theory, the standard text for doctoral students and researchers on the theory of asset pricing and portfolio selection in multiperiod settings under uncertainty. The asset pricing results are based on the three increasingly restrictive assumptions: absence of arbitrage, single-agent optimality, and equilibrium. These results are unified with two key concepts, state prices and martingales. Technicalities are given relatively little emphasis, so as to draw connections between these concepts and to make plain the similarities between discrete and continuous-time models. Readers will be particularly intrigued by this latest edition's most significant new feature: a chapter on corporate securities that offers alternative approaches to the valuation of corporate debt. Also, while much of the continuous-time portion of the theory is based on Brownian motion, this third edition introduces jumps--for example, those associated with Poisson arrivals--in order to accommodate surprise events such as bond defaults. Applications include term-structure models, derivative valuation, and hedging methods. Numerical methods covered include Monte Carlo simulation and finite-difference solutions for partial differential equations. Each chapter provides extensive problem exercises and notes to the literature. A system of appendixes reviews the necessary mathematical concepts. And references have been updated throughout. With this new edition, Dynamic Asset Pricing Theory remains at the head of the field.
Book Synopsis Dynamic Strategies, Asset Pricing Models, and the Out-of-Sample Performance of the Tangency Portfolio by : Cesare Robotti
Download or read book Dynamic Strategies, Asset Pricing Models, and the Out-of-Sample Performance of the Tangency Portfolio written by Cesare Robotti and published by . This book was released on 2014 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, I study the behavior of an investor with unit risk aversion who maximizes a utility function defined over the mean and the variance of a portfolio's return. Conditioning information is accessible without cost and an unconditionally riskless asset is available in the market.The proposed approach makes it possible to compare the performance of a benchmark tangency portfolio formed from the set of unrestricted estimates of portfolio weights) to the performance of a restricted tangency portfolio which uses single-index and multi-index asset pricing models to constrain the first moments of asset returns.The main findings of the paper are summarized as follows: i) The estimates of the constant and time-varying tangency portfolio weights are extremely volatile and imprecise. Using an asset pricing model to constrain mean asset returns eliminates extreme short positions in the underlying securities and improves the precision of the estimates of the weights. ii) Partially restricting mean asset returns according to single-index and multi-index asset pricing models improves the out-of-sample performance of the tangency portfolio. iii) Active investmentstrategies (i.e., strategies that incorporate the role played by conditioning information in investment decisions) strongly dominate passive investment strategies in-sample but do not provide any convincing pattern of improved out-of-sample performance.
Download or read book Asset Pricing written by John H. Cochrane and published by Princeton University Press. This book was released on 2009-04-11 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the prestigious Paul A. Samuelson Award for scholarly writing on lifelong financial security, John Cochrane's Asset Pricing now appears in a revised edition that unifies and brings the science of asset pricing up to date for advanced students and professionals. Cochrane traces the pricing of all assets back to a single idea--price equals expected discounted payoff--that captures the macro-economic risks underlying each security's value. By using a single, stochastic discount factor rather than a separate set of tricks for each asset class, Cochrane builds a unified account of modern asset pricing. He presents applications to stocks, bonds, and options. Each model--consumption based, CAPM, multifactor, term structure, and option pricing--is derived as a different specification of the discounted factor. The discount factor framework also leads to a state-space geometry for mean-variance frontiers and asset pricing models. It puts payoffs in different states of nature on the axes rather than mean and variance of return, leading to a new and conveniently linear geometrical representation of asset pricing ideas. Cochrane approaches empirical work with the Generalized Method of Moments, which studies sample average prices and discounted payoffs to determine whether price does equal expected discounted payoff. He translates between the discount factor, GMM, and state-space language and the beta, mean-variance, and regression language common in empirical work and earlier theory. The book also includes a review of recent empirical work on return predictability, value and other puzzles in the cross section, and equity premium puzzles and their resolution. Written to be a summary for academics and professionals as well as a textbook, this book condenses and advances recent scholarship in financial economics.
