Full textAverage stock returns on industry portfolios are related to industry total market equity and industry market equity concentration. Small industries outperform large industries marginally, while high-concentration industries outperform low-concentration industries significantly. The industry concentration premium persists after controlling for firm size and book-to-market equity ratio. A three-factor model using risk factors associated to industry size and industry concentration compares well to the Fama-French three-factor model, capturing return variation of portfolios formed on industry size, concentration, book-to-market equity, debt-to-equity, dividend-to-price, and earnings-to-price. My results are consistent with traditional economic theory and industry strategic analysis.

This dissertation is aimed at evaluating the risk-return relationship of stocks by incrementing the Fama and French five-factor model (F. FAMA and R. FRENCH, 2015) with two new variables. This was done by creating a six-factor model aimed at capturing the size, value, profitability, investment and governance patterns in average stock returns. An additional seven-factor model was also created by adding a herding factor. Governance and herding were chosen as additional factors because of a hypothesis that they would be relevant in less efficient markets such as Brazil. The evaluation of the two model´s performance versus the traditional five-factor model was performed next, as well as the assessment of relevance of the newly added factors. Testing the six-factor model, it had a similar performance to the five-factor model, and the governance factor proved to be relevant in the Brazilian market. Adding the herding factor weakened the results, although the factor still proved to be relevant in some cases.
O objetivo desta dissertação é avaliar a relação risco-retorno de ações incrementando o modelo de cinco fatores de Fama e French (F. FAMA and R. FRENCH, 2015) com duas novas variáveis. Isso foi feito criando um modelo de seis fatores que busca capturar os padrões de tamanho, valor, lucratividade, investimento e governança nos retornos médios de ações. Um modelo adicional de sete fatores também foi criado adicionando um fator para o efeito manada. A governança e o efeito manada foram escolhidos como fatores adicionais por conta da hipótese de que eles seriam relevantes em mercados menos eficientes como o Brasil. A avaliação da performance dos dois modelos contra o modelo tradicional de cinco fatores foi então realizada, bem como a avaliação da relevância dos novos fatores. Testando o modelo de seis fatores, descobrimos que ele tem uma performance semelhante ao de cinco fatores, e o fator de governança mostrou ser relevante no mercado Brasileiro. Adicionando o fator para o efeito manada enfraqueceu os resultados, embora o fator ainda mostrou-se relevante em alguns casos.

Full textMeasures that are currently underway in the country, forwarded by agents of the electricity sector, reinforce the expectation of developing a solid photovoltaic market in a few years. The photovoltaic systems flexibility, allows plant\'s construction of different capacities, these may be concentrated, covering vast areas of land, as divided into small units, integrated into urban architecture. However, researches have shown that in countries with a large capacity of photovoltaic systems installed, the partial shading of photovoltaic modules is responsible for average losses of 10%. Aiming to add knowledge to the energy sector and contribute to the development of the domestic photovoltaic market, this text aims to present the results of a research, in which was established a model used to build a plug-in that turns Google SketchUp into a free tool, with the ability to estimate the shading factor and irradiation in selected surfaces in a three-dimensional model of a building. Thus, was realized a literature research, responsible for identifying and selecting models used in the various steps, involved in estimating the shading factor and irradiation. After some changes have been implemented, these models converged to a single model that was applied to the development of a plug-in called Solar3DBR. The performance of the Solar3DBR was evaluated through comparisons with the softwares PVsyst and Ecotect, and in actual measurements performed in an experiment. In this experiment irradiance in a partially shaded PV cell and hourly irradiation on inclined plane were monitored. Measurement results allowed to determine the shading factor of the cell, and were compared to simulation results of a three-dimensional model of the system through Solar3DBR. The result of these confrontations demonstrated that the results obtained from the Solar3DBR are similar to the ones presented by PVsyst, Ecotect and actual measurements.

Full textThis dissertation is to explore the risk factors and factor models on Chinese A-share stock market based on the context of Fama-French (FF) factor model. First of all, chapter 1 re-examines the applicability of Fama-French Three-Factor (FF3F) Model and the latest Fama-French Five-Factor (FF5F) Model considering several special features of Chinese stock market. FF3F Model can explain a majority of time-series variation of the Chinese A-share stock returns. The market beta and SMB are important determinants in explaining the cross-sectional variation in the average stock returns over the sample period; however, we find no value premium. Comparing the performance of both FF3F Model and FF5F Model on Chinese A-share stock market, in the presence of profitability and investment factors, FF5F Model seems not capture more variations of expected stock returns than the three-factor model except the six value-weighted portfolios formed on size and operating profitability.Chapter 2 examines whether FF factors SMB and HML proxy for the innovations of selected state variables (aggregate dividend yield, one-month T-bill rate, term spread and default spread) that describe future investment opportunities on Chinese A-share stock market during the research period. Both time-series and cross-sectional regressions are performed on five comparative models using Fama-MacBeth two-stage approach. FF factors don’t lose their explanatory power with or without the presence of the innovations of selected four state variables in both the time-series and cross-sectional examinations. We find that the information contained in innovation of aggregate dividend yields seems totally captured by the combination of market beta and size factor. FF factors might have played a limited role in capturing alternative investment opportunities proxied by innovations of the selected four state variables.Chapter 3 investigates whether FF factors proxy for distress risk factor and whether different methods of constructing factors result in the different outcomes. The empirical results suggest that there is no significant evidence that FF factors are proxying for distress risk on Chinese A-share stock market. Comparing the time-series regression results by using two different methods, the distress risk factor constructed based on DLI seems to perform slightly better than that constructed based on O-score in capturing time-series average returns. However, the distress risk factor is not an important determinant of cross-sectional average returns, and FF factors cannot proxy as distress risk factor in the cross-section on Chinese A-share stock market

Este estudo tem o objetivo de analisar se a inclusão do fator Payout no modelo de três fatores de Fama e French (1993) é relevante para explicação do retorno das empresas cotadas na BM&FBOVESPA entre o período de 2004 e 2014. O Payout avalia o nível de pagamento de dividendos. O prêmio pelo fator Payout é obtido pela diferença dos retornos entre as empresas que pagaram Payout Incremental – percentual de dividendos maior do que versa a legislação – e o retorno daquelas empresas que não pagaram dividendos. O método utilizado nesse trabalho baseia-se no modelo de Fama e French (1993), onde o fator Payout foi adicionado aos fatores prêmio pelo risco de mercado (RM-RF), prêmio pelo fator tamanho (SMB) e prêmio pelo fator book-to-market (HML) criando um novo modelo de 4 fatores. O poder explicativo desse modelo foi testado em face do retorno de 12 carteiras criadas a partir da ortogonalização dos desses fatores. Os resultados indicam que o fator Payout é significativo no modelo e que este fator geralmente possui uma relação negativa com o retorno das carteiras. O modelo consegue explicar melhor o retorno de sete dentre as doze carteiras estudadas, dessas destacam-se as carteiras de pequenas, de alto valor e que pagaram dividendos incrementais, pequenas, de baixo valor e que pagaram dividendos incrementais, pequenas, de baixo valor e que não pagaram dividendos, com um poder explicativo de mais de 70%. Para as carteiras grande, de alto valor e que não pagaram dividendos, grande, de baixo valor e que não pagaram dividendos, pequenas, de baixo valor e que pagaram dividendos mínimo, pequenas, de alto valor e que não pagaram dividendos, o modelo explica o retorno em mais de 50% com as variáveis apresentadas. A variável Payout não foi significativa apenas para a carteira pequena, de baixo valor e que pagaram dividendos. Portanto, a inclusão do fator Payout ao modelo de Fama e French (1993) possui relevância para os estudos de avaliação de portfólios. Este estudo contribui para as discussões e aprimoramento dos modelos de precificação de ativos no mercado brasileiro.
This study aims to analyze whether the inclusion of the Payout factor on the three factors of Fama and French (1993) is relevant to an explanation of the return of the companies listed on the BM&FBOVESPA between 2004 and 2014. The Payout evaluates the level of payment of dividends. The premium of the Payout’s factor is obtained by the difference of returns among the companies that paid the dividend percentage – Incremental Payout higher than what legislation suggests – and the return of the companies that did not pay dividends. The method used in this paper is based on Fame and French (1993) model’s, which the Payout factor was added to by the market risk premium (RM-RF), an award by the factor (SMB) size and prize for the book-to-market factor (HML) creating a new model of 4 factors. The explanatory power of this model was tested in the face of the return of 12 portfolios created by orthogonalizing these factors. The results indicate that the Payout factor is significant in the model and that this factor generally has a negative relationship with the return of portfolios. The model can explain better the return of seven from twelve portfolios studied. From these portfolios stands out portfolios with little value, high value and that paid dividends, small, low-value and that paid dividends, small, low-value and that did not pay dividends, with an explanatory power of over 70%. For great portfolios, high value and that did not pay dividends, large, low-value and that did not pay dividends, small, low-value and that paid minimum dividends, small, high value and that did not pay dividends, the model explains the return in more than 50% with the variables presented. The variable Payout was not significant for small, low portfolio value and that paid dividends. Therefore, the inclusion of the Payout factor model of Fame and French (1993) has relevance to portfolio assessment studies. This study contributes to the discussion and improvement of asset pricing models in the Brazilian market.

Full textIn this study we will examine if overreactions occurred on the Stockholm Stock Exchange during period 2002-2016. Winner- and loser portfolios were formed based on past monthly returns to see if investors overreact and by doing that cause reversal effects later on. Our study discovers short-term reversals, but in the long run investors benefit by following the overall trend on the stock market. Expanding our study to the Fama-French three-factor model we suggest that reversals in stock prices does not enable investors to gain statistically significant positive alphas on the Stockholm Stock Exchange. On the contrary, returns are driven by the factors of firm size and -value rather than behavioral biases of investors.

Full textThe purpose of this thesis was to examine if the stated motive for a seasoned equity offering (SEO) affects company valuation, post-SEO. This was accomplished by calculating abnormal returns for a sample containing 203 SEOs over a 14 year period between 2005 and 2018. All companies being listed on Nasdaq OMX Stockholm during the time of their respective equity offering. By providing three different measurements for abnormal return (CAR, BHAR, and FF3M) as well as performing multiple regression analysis, the study finds significant evidence for general underperformance following the SEO. This is true for when the motive is stated as recapitalization or general corporate-related purposes. When the motive is stated as investment, the study finds significant evidence for post-SEO overperformance.

Full textInvestors and companies can choose between multiple pricing models to predict the price of shares. With the known one factor model CAPM, researchers have developed a model that consider more than just the market factor. This resulted in the creation of the Fama & French three factor model (FF3), which also includes the size factor SMB and the value factor HML. The purpose of the study is to evaluate two pricing models, CAPM and FF3, to assess their performance when evaluating expected returns. Previous research often deal with international markets and model performance of portfolios. We study selected individual Swedish shares for January 2011 to December 2015 by replicating previous research by Bartholdy & Peare (2005). Selected companies are analysed by regressions for the models to be able to evaluate these separately, and to see if FF3 has a higher degree of explanation than CAPM for individual Swedish shares. The result of the study shows that both CAPM and FF3 are applicable for selected individual Swedish shares. There is a difference in the adjusted degree of explanation between the models but it is marginal. In conclusion, the study contributes with the knowledge that CAPM and FF3 can be applied to individual Swedish shares, but there is no major difference in the choice of these two models.

Full textProtection mechanisms to shareholders and creditors were created promising that companies that invest in corporate governance would be appreciated. This would be possible because investors would be less exposed to the expropriation of their own capital by means of corporate governance mechanisms that ensure their rights and, accordingly, this would facilitate the sale of their shares and securities, the access to the capital market and a decrease in the cost of capital, appreciating thus the company. In this context, this paper has the purpose of analyzing the relationship between corporate governance and the cost of capital in Brazilian publicly-traded companies. This study determines whether the companies that adopt corporate governance practices, measured by Bovespa\'s (São Paulo Stock Exchange) corporate governance different levels, have a lower cost of capital when compared to companies that do not adopt these practices. To calculate the cost of capital, the CAPM and the Three-factor model were used to verify whether the relationship with corporate governance practices depends or not on the method adopted. The multiple linear regression was used to analyze statistics and the dependent variable was the cost of capital and the independent variables were the degree of financial leverage, the degree of operating leverage, the industries, the company\'s degree of intangibility and the time the company is listed on Bovespa. A positive relationship between the cost of capital, measured by the CAPM, and companies that adopt any of the corporate governance different levels was found, namely, the cost of capital is higher for companies that adhered to these practices. In the other analyses, the corporate governance was not significant. In this context, the hypothesis determining that a lower cost of capital is related to corporate governance is not confirmed. Therefore, the companies could be appreciated by increasing the expected cash flow and not by decreasing the cost of capital. We may also consider that corporate governance practices would be adopted by companies subject to a higher risk and that intend to reduce it by adopting protection measures to the minority shareholder, or that the company\'s beta that represents the CAPM would show a higher performance in relation to the market and, in this case, this would not highlight the risk, but a better performance of the company\'s shares when compared to the market.

Yalcin, Ozge. "The Performance Evaluation And Persistence Of A Type Mutual Funds In Turkey." Thesis, METU, 2012. http://etd.lib.metu.edu.tr/upload/12614099/index.pdf.
Full texts Three Factor Model are applied. Persistency analysis is done by tracking the relative fund performances on a monthly basis. The results of this study indicate that for the sample period, Turkish A Type mutual funds neither overperform nor underperform the overall market. Nearly all Jensen&rsquo
s alphas are found to be zero, statistically significant. This is also an implication that the mutual funds are earning their expected returns in an efficient mutual fund market in Turkey. The Fama-French&rsquo
s three factor model shows slightly better performance, on the other hand. The size and book to market equity factors are not found significant in general, however they are found jointly significant in all regressions. Persistency is analyzed by tracking the mutual fund erformances on monthly basis. When some mutual funds showed negative or positive performance persistency during the period individually, but the overall picture demonstrates a balanced distribution of performance groups. The number Loser-Loser performances is slightly more than the other three groups, resulting in a tendency for short term negative persistency for the sample analyzed between the period of January 2003 to June 2011.

Full textHållbarhet har blivit en stor samhällstrend och intresset för hållbara investeringar har ökat bland investerare. Syftet med denna studie är att undersöka hur hållbarhet påverkar Sverigefonders avkastning och risk. Eftersom forskning kring hållbarhetens påverkan på fonder fokuserar mestadels på investeringar utanför Sverige har denna studie avgränsat sig till Sverigefonder för att fylla luckan i forskningen. Studien analyserar 67 Sverigefonder under 2015-2019 med hjälp av olika modeller såsom CAPM, Fama-French trefaktormodell och Sharpekvot. Vidare mäts fondernas hållbarhet med hjälp av Morningstar hållbarhetsbetyg. Resultat visar inga tecken på linjär regression mellan hållbarhet och resultat från olika modeller samt studiens resultat är inte statistiskt signifikanta. Därmed är studiens slutsats att det inte är hållbarhet som påverkar på risk och avkastning bland Sverigefonderna utan det kan vara andra faktorer som inte tagits hänsyn till i denna studie. Däremot visar tidigare forskning att hållbara fonder presterar bättre och är mer stabila under kristider. Denna studie har inte undersökt Sverigefonderna under kristider men detta kan vara ett intressant ämne för framtida forskning.

To collect and analyze the longitudinal data is a very important approach to understand the phenomenon of development in the real world. Ideally, researchers who are interested in using a longitudinal framework would prefer collecting data at more than two points in time because it can provide a deeper understanding of the developmental processes. However, in real scenarios, data may only be collected at two-time points. With only two-wave data, the second-order latent growth model (SOLGM) could not be used. The current dissertation compared the performance of two-wave models (longitudinal common factor model and latent change score model) with the three-wave SOLGM in order to better understand how the estimation quality of two-wave models could be comparable to the tree-wave model. The results show that on average, the estimation from two-wave models is identical to the ones from the three-wave model. So in real data analysis with only one sample, the point estimate by two-wave models should be very closed to that of the three-wave model. But this estimation may not be as accurate as it is obtained by the three-wave model when the latent variable has large variability in the first or last time point. This latent variable is more likely to exist as a statelike construct in the real world. Therefore, the current study could provide a reference framework for substantial researchers who could only have access to two-wave data but are still interested in estimating the growth effect that supposed to obtain by three-wave SOLGM.

Electronic-based devices and loads have been essential parts of modern society founded on rapid advancements of information technologies. Along with the progress, power supplying and charging of electronic products become routinized in daily lives, but still remain critical requisites for reliable operations. In many power-electronics-based supplying systems, ac-dc power-factor correction (PFC) circuits are generally located at front-end to feed back-end loads from universal ac-line sources. Since PFC stages have a key role in regulating ac-side current quality and dc-side voltage control, the importance of PFC performances cannot be emphasized enough from entire system point of view. Thus, advanced control schemes for PFC converters have been developed in quantity to achieve efficient operations and competent power qualities such as high power factor, low harmonic distortions and low electromagnetic interferences (EMI) noises. In this dissertation, a sort of PFC topologies named three-level boost (TLB) converter is chosen for target topology. Based on inherent three-level waveform capability of the topology, multiple zero-current switching (ZCS) control schemes are proposed. Compared to many conventional two-level PFC topologies, TLB PFC can provide additional degree-of-freedom to current modulation. The increased control flexibility can realize improvements of various waveform qualities including peak current stress, switching frequency range, harmonics and EMI amplitude. From the experimental results in this dissertation, improvements of waveform qualities in TLB PFC with the proposed schemes are verified with comparison to two-level current control schemes; in terms of efficiency, the results show that TLB PFC with the proposed schemes can have similar converter efficiency with conventional two-level boost converter in spite of increased component counts in the topology. Further, the proposed three-level control schemes can be utilized in adjustable forms to accomplish different control objectives depending on system characteristics and applications. In each chapter of this dissertation, a novel control scheme is proposed and explained with details of operation principle, key equations and digital implementation method. All the effectiveness of proposals and analyses are validated by a proper set of experimental results with a TLB PFC prototype.

Full textThis work presents the study and implementation of an ac-dc Ćuk converter based on the three state switching cells applied in charger stations for electric vehicles. This converter has, as main characteristics, reduction of conducting power losses in the semiconductors, a single stage topology and current source behavior for both input and output terminals. As drawbacks, the topology presents: the voltage across the semiconductors is equal to the sum of the input and the output voltages, and a difference between the current values through the semiconductors caused by an inappropriate layout of the power prototypes or by a lack of symmetry between the control signals. The analysis of the converter is made through the qualitative and quantitative studies, beyond the analysis of the semiconductor losses which are presented as well. The current and voltage of the battery are controlled by the average current mode technique, which consist in a fast current control loop if compared with the terminals battery voltage control loop. The topology is design for 1 kW output power, 220 V in input voltage and 162 V in the output terminals (12 batteries in series connection). Experimental results for resistive load, as well batteries, are shown in order to verify the functionalities of the topology and its characteristics.
Este trabalho apresenta o estudo e desenvolvimento de um conversor ca-cc Ćuk baseado na cÃlula de comutaÃÃo trÃs estados para aplicaÃÃo em carregadores de baterias para veÃculos elÃtricos. As principais caracterÃsticas deste conversor sÃo: a reduÃÃo das perdas por conduÃÃo nos interruptores controlados, um Ãnico estÃgio de processamento de potÃncia e caracterÃstica de fonte de corrente na entrada e na saÃda. Como inconvenientes a topologia apresenta: a tensÃo sobre os semicondutores igual à soma das tensÃes de entrada e saÃda e o desequilÃbrio de corrente atravÃs dos componentes quando hà assimetria no layout da placa de potÃncia ou nos sinais de comando dos interruptores. Um estudo teÃrico à realizado atravÃs das anÃlises qualitativa e quantitativa, alÃm das anÃlises do processo de comutaÃÃo e das perdas nos componentes do conversor. Para controlar o fluxo de potÃncia da rede elÃtrica para as baterias à utilizada a estratÃgia de controle modo corrente mÃdia, sendo que, a mesma apresenta uma malha de corrente rÃpida que monitora a corrente de entrada e uma malha de tensÃo lenta que supervisiona a tensÃo sobre os terminais da bateria. Neste trabalho à realizado o projeto do carregador de baterias para aplicaÃÃo em veÃculos elÃtricos com 1 kW de potÃncia, tensÃo de entrada eficaz de 220 V e tensÃo de saÃda de 162 V, correspondente a 12 baterias conectadas em sÃrie. Um protÃtipo com as especificaÃÃes indicadas foi construÃdo e testado experimentalmente em laboratÃrio e os resultados de simulaÃÃo e experimentais obtidos sÃo utilizados para validar a anÃlise teÃrica e o projeto realizado. Foram realizados testes com carga puramente resistiva e em seguida com um banco de baterias, que comprovaram o funcionamento da topologia.
