Book Description
Recent work by Richard Roll has challenged the worth of portfolio performance measures based on the capital asset pricing model. This paper demonstrates that Roll's conclusions are due to his inappropriate use of a 'truly' ex-ante efficient index. Using a choice and information theoretic framework, an appropriate index is shown to be efficient relative to to the probabilities assessed by the 'market.' Residual analyses and portfolio performance tests, using such an index, yield meaningful results for a wide class of information structures. Roll's primary criticisms, however, relate to tests of the model itself. We argue that these criticisms are vastly overstated.

Book Description
The problem addressed in this dissertation research was the inability of the single-factor capital asset pricing model (CAPM) to identify relevant risk factors that investors consider in forming their return expectations for investing in individual stocks. Identifying the appropriate risk factors is important for investment decision making and is pertinent to the formation of stocks' prices in the stock market. Therefore, the purpose of this study was to examine theoretical and empirical validity of the CAPM and to develop and test a multifactor model to address and resolve the empirical shortcomings of the single-factor CAPM. To verify the empirical validity of the standard CAPM and of the multifactor model, five hypotheses were developed and tested against historical monthly data for U.S. public companies. Testing the CAPM hypothesis revealed that the explanatory power of the overall stock market rate of return in explaining individual stock's expected rates of return is very weak, suggesting the existence of other risk factors. Testing of the other hypotheses verified that the implied volatility of the overall market as a systematic risk factor and the companies' size and financial leverage as nonsystematic risk factors are important in determining stock's expected returns and investors should consider these factors in their investment decisions. The findings of this research have important implications for social change. The outcome of this study can change the way individual and institutional investors as well as corporations make investment decisions and thus change the equilibrium prices in the stock market. These changes in turn could lead to significant changes in the resource allocation in the economy, in the economy's production capacity and production composition, and in the employment structure of the society.

Book Description
Our research indicated that there is a linear relationship between risk and return and higher risk is associated with higher average return. These results are consistent with the implications of both Sharpe-Lintner version and Black version of the CAPM. Furthermore, our results did not reject the hypotheses that E(Y0)=Rf and E(Y1)=Rm-Rf. therefore, the empirical results of this study supported all the implications of the Sharpe-Lintner CAPM.

Book Description
The main purpose of the project is to relate the risk of assets to their expecte d returns (mainly assets that are traded on a handful of developed markets, incl uding US, Japanese, French, and German exchanges). In order to do so, we refer t o the Capital Asset Pricing Model (CAPM) which consists of relating the risk of an asset to its expected return by comparing it to the overall stock market. Thi s model is based on the existence of a linear relationship between the expected return of a given asset, and the market rate of return. Consequently, any return that is not explained by this linear relationship (abnormal return) will lead u s to reject the theoretical linear relationship stated and formulated in the CAP M. The first chapter will introduce the topic. The second chapter consists of prese nting the CAPM, its critiques and extensions. In the third chapter, a literature review will be conducted. Then, in the fourth chapter I will undertake time ser ies/cross-sectional analyses of the aforementioned equity markets in order to te st the CAPM model itself. The same stocks will be tested using the international version of the model. Finally, in the fifth chapter I will conclude with the im plications of my findings for asset pricing and investment.

Book Description
An introduction to the theory and methods of empirical asset pricing, integrating classical foundations with recent developments. This book offers a comprehensive advanced introduction to asset pricing, the study of models for the prices and returns of various securities. The focus is empirical, emphasizing how the models relate to the data. The book offers a uniquely integrated treatment, combining classical foundations with more recent developments in the literature and relating some of the material to applications in investment management. It covers the theory of empirical asset pricing, the main empirical methods, and a range of applied topics. The book introduces the theory of empirical asset pricing through three main paradigms: mean variance analysis, stochastic discount factors, and beta pricing models. It describes empirical methods, beginning with the generalized method of moments (GMM) and viewing other methods as special cases of GMM; offers a comprehensive review of fund performance evaluation; and presents selected applied topics, including a substantial chapter on predictability in asset markets that covers predicting the level of returns, volatility and higher moments, and predicting cross-sectional differences in returns. Other chapters cover production-based asset pricing, long-run risk models, the Campbell-Shiller approximation, the debate on covariance versus characteristics, and the relation of volatility to the cross-section of stock returns. An extensive reference section captures the current state of the field. The book is intended for use by graduate students in finance and economics; it can also serve as a reference for professionals.

Book Description
Bachelor Thesis from the year 2020 in the subject Business economics - Banking, Stock Exchanges, Insurance, Accounting, grade: 1,3, Munich University of Applied Sciences, language: English, abstract: The goal of this study is thus to determine the best available asset pricing model in Germany and whether the use of pre-existing datasets, with the factors already calculated, brings results as accurate as a custom dataset. This is relevant in Germany as the CAPM is still the most commonly used way to compute the cost of equity with 34% of companies using it. Another 16% of companies are using asset pricing models with additional risk factors. To determine the answer to this, this study will look into the aforementioned three most commonly used models: the CAPM, the Fama and French three-factor model and the Carhart four-factor model. After explaining the background and functioning of the CAPM, this study will show the flaws within the model and how these flaws led to extensions of the CAPM. Each model will then be statistically analyzed with three distinct sets of data. Two of these are publicly available, while the last has been calculated for this study. Lastly, to understand how the difference in data used can influence the results from asset pricing models, the runtime and underlying factor of datasets will be modified, re-analyzed and compared to the initial results.
