Socially responsible investing has presented itself as a growing, multifaceted, advanced and sophisticated investment philosophy. Socially responsible investment (SRI) involves incorporating social, ethical and responsible investment objectives with financial investment objectives during the investment decision-making process. Social, ethical and responsible investment objectives are set in line with environmental, social and corporate governance (ESG) criteria which are established within the SRI strategy followed. SRI strategies include screening (negative, positive and best-of-sector), shareholder activism and cause-based investing. Although international SRI markets such as that of the United States of America and the United Kingdom are sophisticated and established markets, the South African SRI market is still relatively new and is yet to reach its full potential. Thus, as a growing market, little research regarding the long term risk-adjusted performance of SRI funds in South Africa has been conducted. The long term risk-adjusted performance of the sample of SRI funds was measured through the use of five risk-adjusted performance measures, namely the Treynor ratio, Sharpe ratio, Jensen’s alpha, Sortino ratio and Omega ratio, and through the use of three performance measurement models which included the capital asset pricing model (CAPM), Fama-French three-factor model and Carhart four-factor model. The risk-adjusted performance of the sample of SRI funds was measured with the intent to establish if these funds out- or underperformed against three benchmark categories, namely the Financial Times Stock Exchange/Johannesburg Stock Exchange (FTSE/JSE) SRI Index, a matched sample of conventional investment (non-SRI) funds and the FTSE/JSE All Share Index. The probable effect of the 2007/08 global financial crisis was also measured to analyse whether such a hazardous market event affected the performance of the SRI funds. According to the results and findings, the risk-adjusted performance of the SRI funds has improved over the research period. However, the SRI funds neither outperformed nor underperformed against the three benchmark categories over the research period. The performance measurement models’ analysis indicated that the SRI funds were less sensitive to market fluctuations, more exposed to small capitalisation portfolios, more growth-oriented, and exhibited significant momentum after the period of the 2007/08 global financial crisis. Furthermore, the analysis indicated that the SRI funds significantly underperformed against the non-SRI funds during the Performance of socially responsible investment funds in South Africa research period. Mixed results were obtained with regards to the probable effect of the 2007/08 global financial crisis on the performance of the SRI funds.

隨著經濟發展，國民所得水準提高，國民儲蓄成為資本形成的重要來源，而資本市場之功能便在於匯集民間儲蓄，將其導入國內的各項實質建中，是故一個有效率的、健全的資本市場，不僅能讓資金之供需雙方互蒙其利，更可使整體經濟社會的實質財富與所得，隨著資金供給雙方的交互行為而得以持續成長。 　　在台灣目前資本市場發行及流通之信用工具中，不論是初級市場發行額，抑或是次級市場交易額，股票市場一直佔有最重要的地位，所以股票市場也就成為企業籌措長期資金最為倚重的信用工具。 　　正因為股票市場具有如此之重要性，因此本文先從理論與台灣近幾年來的相關實證，針對台灣股票市場效率性做一番釐清，再從所得出之結論進一步借用Galeotti & Schiantarelli (1994)的研究，將股價區分成基本面與非基本面，以及各自適當的代理變數，推導出投資與這些代理變數之間的關係。 　　最後就民國76年5月至83年11月期間，以台灣所有上市公司為研究對象做實證分析。 　　本研究之主要發現如下： 　　1. 台灣股價波動偏離基本價值具有市場異常現象，不符合效率市場假說。 　　2. 由股票市場價值區分出之基本面與非基本面因素，對投資均會產生影響，其中又以落後兩期之解釋變數最為顯著。此結果介於Bosworth (1975)與Merton & Fischer (1984)兩篇研究之間，非基本面亦會影響投資 決策，但非基本面之效果小於基本面效果。

One could argue that the most discussed topic in finance is whether or not it is possible to “beat the market”. Even though many people claim to do this, there is little evidence to support the idea that one can consistently beat the market over a long period of time. There are indeed several examples of investors who have managed to outperform the market consistently for a long time, but the efforts of these individuals or institutions could by many be considered to be pure luck. One of the many strategies that have been evaluated by several researchers and is said to generate a risk adjusted return greater than that of the market, is one based on the P/E-effect. This strategy is based on the financial ratio P/E – price divided by earnings – and used by constructing portfolios consisting of stocks with low P/E ratios. Several studies have confirmed the existence of the P/E-effect on various stock markets around the world and over different time periods. On the Swedish market, however, few studies have generated the same results. Most of these studies can be considered to be insufficient with regards to sample sizes and methods, spawning a need for more extensive studies. We have examined the P/E strategy on the Swedish Stock Exchange (SSE) between 2004 and 2012. The sample included 358 companies (excluding financial companies) with available necessary data. The stocks were divided into five portfolios based on their yearly P/E ratios (low to high), upon which the monthly returns of the individual stocks were calculated using a logarithmic formula. The returns were also risk adjusted using the Capital Asset Pricing Model (CAPM), followed by a regression analysis to see if possible abnormal returns could be considered to be statistically significant for the examined time period. The results of our study indicate that the P/E effect is not present on the Swedish Stock Exchange during the examined time period, and we therefore conclude that it was not possible to utilize a strategy based on the P/E effect between 2004 and 2012 in order to achieve an abnormal return. The results can be used to argue that the Swedish stock market is more efficient than for example the U.S. stock market where the P/E effect has been found to exist.

Previous research has confirmed the existence of a value premium in a wide array of markets and using this value stock anomaly has yielded superior performance. This thesis investigates if one could take advantage of the existence of a value premium to deploy a dynamic investment strategy on the Swedish stock market (OMXS30) with focus on minimizing risk to achieve higher risk adjusted performance than the stock market index. The investment strategy implemented use Market-to-Book-Value to screen for both entry and exit signals and Modern Portfolio Theory, using the minimum-variance portfolio with short-selling constraints, to allocate assets within the portfolio. The investment strategy is evaluated using the Modigliani-Modigliani Risk Adjusted Performance measure. Conclusions from the thesis are that the strategy does outperform the Swedish stock market index, both in terms of nominal return and risk-adjusted performance. The suboptimal behaviour of investors where they overreact  to signals and unconsciously rely on heuristics is used to explain why this is possible. Market-to-Book-Value, using the first quartile as entry signal and third quartile as exit signal, is considered to be a successful key ratio to screen for value stocks.

Idag äger många svenskar andelar i olika fonder. Detta beror delvis på att det allmänna pensionssystemet i Sverige idag består av en premiepensionsdel, där individen kan göra ett individuellt val hur dennes pensionspengar ska investeras. Gemensamt för investerare är att de vill erhålla en god avkastning. Ett vanligt sätt att bedöma förväntad avkastning i en finansiell tillgång kallas Capital Asset Pricing Model, eller CAPM. Detta är en mycket behandlad, debatterad och även kritiserad modell. Förutom CAPM utgår studien från en nyare teori som heter Black Swan theory. År 2007 presenterade Taleb sin teori om Black Swan. Han menar att en Black Swan är en händelse som avviker från det normala, har långtgående effekter och som efteråt får naturliga förklaringar. Ett potentiellt Swan-fenomen är finanskrisen. Om nu finanskrisen kan räknas som ett Swan-fenomen innebär det att den finansiella verkligheten har förändrats. Om nu den finansiella världen har påverkats så finns det anledning att tro att även modeller och deras överensstämmelse med verkligheten har påverkats. Det är detta vi i denna studie ämnar att undersöka och mynnar därför ut i frågeställningen: Var CAPM en fungerande modell gällande Sverigefonder åren 2005-2014? Studiens syfte lyder enligt följande: Att undersöka hur väl CAPM:s prediktion av förväntad avkastning i Sverigefonder stämmer överens med den faktiska avkastningen. Vi vill också genom undersökningen se ifall denna överensstämmelse har förändrats under vår undersökningsperiod och ifall detta i sådana fall kan kopplas till ett potentiellt Swan-fenomen som finanskrisen. Med teoretisk utgångspunkt i modern portföljvalsteori, CAPM och Black Swan theory undersöks sambandet mellan betavärde och avkastning i Sverigefonder. Vi utgår från en positivistisk kunskapssyn och genom en deduktiv ansats genomförs en regressionsanalys för att svara på vår frågeställning. Det empiriska materialet består av månadsavkastning från de valda fonderna, riskfri ränta och marknadsindexets avkastning. I vår studie hade vi endast ett år med signifikant positivt samband mellan beta och avkastning (som försvann i och med heteroskedasticitet i datamaterialet). Vi hade däremot ett år med negativt signifikans (2014) samtidigt som en positiv marknad, vilket inte överensstämmer med tidigare empiriska undersökningar. Vissa år ser det ut som att det finns samband genom att grafiskt titta på våra figurer i resultatdelen, men det är även år där det motsatta förhållandet finns. Med resultaten och analysen i åtanke kan vi inte förkasta nollhypotesen 2005-2013 (det finns inget samband mellan beta och avkastning).

The thesis deals with modern portfolio theory. The theoretical part of the thesis describes the historical development of portfolio optimization and presents the basic theoretical background of the Markowitz model, the Tobin model and the Capital asset pricing model. In the practical part of the thesis, the models are applied to real data from two Czech securities markets, PSE and RM-S. An optimal portfolios composition is proposed by the three models mentioned above and then the outputs of the models are compared to the real datas from the next period. Finally, the benefits and drawbacks of the used models are evaluated.

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.

No. of bitstreams: 1 Dissertação EPGE_Victor Sousa.pdf: 2888885 bytes, checksum: 334b8886f93dd9c06eae5bf11b9ea19d (MD5) Previous issue date: 2015-05-15 / In this work we analyze the systematic risk implied in the Brazilian electricity distribution sector and compare it with the evolution of regulatory return rate (WACC Regulatory), in order to identify the presence of an additional risk premium with characteristics of regulatory risk. The energy distribution sector and its energy tariffs (price-caps) are regulated by the Brazilian Electricity Regulatory Agency (ANEEL). The agency performs tariff revisions, every four/five years, in order to reestablish the financial-economic balance of concessionaires and to provide any adjustments to the regulatory model. The main step consists in measure the minimum regulatory return to reward the invested capital. Currently the sector goes through the 4th cycle of rate review (form 2015 to 2019) and, unlike the first two processes; ANEEL does not include the regulatory risk component in the composition of the Regulatory WACC (from CAPM methodology). Despite advances in the creation and consolidation of the regulatory model, the sector has faced serious problems in the regulatory/political front and huge financial losses in all electricity segments, resulting in a significant increase in systematic risk. The main sector’s events and their side-effects were analyzed in this work. In order to identify factors that explain the presence of additional risk in electric utilities, this work analyzes the evolution of some electricity distributors’ betas and applied a multi-factor panel data model. The main conclusion is that regulatory instability and institutional uncertainties affects the sector`systematic risk (betas) and show evidences to support the presence of a non-diversifiable regulatory risk. On the other hand, a stable and properly regulatory framework reduces the variance of returns, reduces the betas and the required rate of return for investments in a sector that is capital intensive and long-term investment. / Este trabalho objetiva analisar o risco sistemático presente no setor de distribuição de energia elétrica, avaliar a evolução da taxa de retorno regulatória (WACC Regulatório) e identificar a presença de um prêmio de risco adicional com características de risco regulatório. O setor de distribuição de energia elétrica por seguir a lógica de monopólio natural é regulado pelo Estado. Nesse sentido, de forma periódica (geralmente a cada 4 anos), a agência reguladora realiza um processo de revisão tarifária com objetivo de reestabelecer o equilíbrio econômico-financeiro das concessionárias, além de promover eventuais ajustes no modelo regulatório. Em uma das etapas do processo é definida a taxa de remuneração regulatória com objetivo de remunerar o capital investido frente aos riscos assumidos pela companhia. Atualmente o setor passa pelo 4ª Ciclo de Revisão Tarifária '4CRTP', compreendendo o período de 2015 a 2019 e, ao contrário dos dois primeiros processos, a ANEEL não inclui o componente de risco regulatório na formação do custo de capital próprio. Entretanto, o Sistema Elétrico Brasileiro, apesar dos avanços com a criação e consolidação do modelo institucional, tem enfrentado graves problemas e elevadas perdas financeiras em todos os segmentos. Com falhas de implementação, os esforços governamentais geraram problemas ainda mais severos, culminado com aumento significativo do risco sistemático. Os principais acontecimentos e seus efeitos foram analisados neste trabalho. De forma a identificar fatores que explicam a presença adicional de risco nas empresas de energia elétrica, foi analisada a evolução das medidas de risco sistemáticos (betas) de algumas empresas do setor elétrico e aplicado um modelo econométrico de regressão de multi-fatores em dados em painel. A principal conclusão é que a instabilidade regulatória e insegurança institucional afeta o risco sistemático das empresas (betas) e torna evidente a presença de um risco regulatório não diversificável. Por outro lado, uma regulação feita de forma adequada reduz a variância dos retornos, reduz os betas e a taxa de retorno requerida para investimentos em um setor que é intensivo em capital e de longo prazo.
