El presente trabajo de investigación analiza el estado del arte de los ajustes y adaptaciones que se han impuesto al modelo Capital Asset Pricing Model (CAPM) para habilitar su aplicabilidad en mercados emergentes, con el fin de valorar correctamente los activos financieros y estimar la rentabilidad esperada en función del riesgo, es justo mencionar que, desde la publicación del modelo han surgido constantes críticas que lo califican de ineficaz en mercados emergentes, basándose particularmente en que, el modelo representa el riesgo a través de una sola variable que es medida por el riesgo sistemático y que fue originalmente diseñada para mercados desarrollados; en tal sentido, se han presentado propuestas de diversos especialistas que con sus teorías recomiendan ajustar el beta o ponderarlo, otras propuestas sugieren incluir variables como el diferencial de crédito, riesgo país y lambda, con lo que sostienen que es significativamente importante la necesidad de tener que adecuar el modelo a mercados emergentes caracterizados particularmente por ser riesgosos y tener alta volatilidad debido a los constantes cambios en sus variables económicos y financieros. / The following research analyzes the state of the art of the adjustments and adaptations imposed on the Capital Asset Pricing Model (CAPM) in order to enable its applicability on emerging markets, with the aim to value properly financial assets as well as estimate the expected profitability depending on the risk, It is fair to mention that, since the publication of the model, there has been severe criticism on its effectiveness for emerging markets, based on the fact that, the model displays the risk through a single variable that is measured by the systematic risk and that was originally designed for developed markets; in this sense, several proposals have been introduced by specialists suggesting wiht his theories to either adjust the Beta or weighted it, and other proposals suggest including variables such as credit spread, country risk and lambda, with which they maintain that it would be of the utmost importance to adapt the model to emerging markets, particularly characterized for being risky and have feature high volatility due to the constant fluctuations both in their economic and financial variables. / Trabajo de Suficiencia Profesional

Yes / This paper examines the role of institutional investor sentiment in determination of the beta-return relation. Empirical evidence documents a positive (negative) beta-return relation over bearish (bullish) periods, implying that institutional investors can also be sentiment traders.

This thesis investigates pricing-performance of two recently developed multifactor asset-pricing models with the implementation of dual-betas dependent upon prevailing market-conditions. The models included in the study are the Fama and French five-factor model and the Q-factor model by Hou, Xue and Zhang. We test the models on cross-sectional Swedish stock-market data between 2003 and 2015 from the Large-, Mid- and Small Cap-lists and their respective precursors. The models are tested in their ability to explain portfolios sorted on firm beta-values, on a twelve-year period as well as a six-year period characterized by changing market directions and high market volatility.  In our study, we support the presence of changing risk-return relationship in up and down market states by estimating separate market betas with the risk-free rate as threshold. However, we do not find the isolated and volatile period to give rise to a larger difference in the up and down market betas. We consistently find the models to have a decreasing explanatory power on the portfolios of firms with lower beta values. We also find the largest difference in the up and down market betas occurring in the low beta portfolios, suggesting that this is causing measurement problems in the models. While making the models conditional, the measurement problem with the static beta seems to be reduced for the portfolios where the difference between up and down betas differ most. In the applied context, we conclude the conditional dual beta adds explanatory power in the models when the market beta differs in up and down market states.  The insights of this thesis support the method of making the market-beta conditional as suggested by Pettengill, Sundaram & Mathur (Pettengill, et al., 1995), in new multifactor models.

This essay will compare the capital asset pricing model (CAPM), Fama and French threefactor model and Carhart´s four-factor model, to see which of these models that can explain portfolio excess returns best on the Swedish stock market. This thesis will tempt to validate the three and four-factor models because of the limited amount of research done on the Swedish stock market. The results indicate that the three-factor model improves explanatory power for portfolio returns in comparison to the CAPM, and the four-factor model gives a small improvement in the explanatory power compared to the three-factor model. The results also indicate that all models have a low explanatory power when the market is volatile.

1.3. Research Questions. With this in mind, the research questions of this work are: 1. Is the Capital Asset Pricing Model still applicable despite the heavy impact of the financial crisis on the financial systems? 2. What happens to this model when the risk free rate approaches zero? 3. Is there a relationship between the riskiness of an asset and the risk-free interestrate when the latter is approaching the zero level?
