The point of this thesis is to compare classic asset pricing models using historic UK data. It looks at three of the most commonly used asset pricing models in Finance and tests the suitability of each for the UK market. The models considered are the Capital Asset Pricing Model (1964, 65 and 66) (CAPM), the Fama-French 3-Factor Model (1993) (FF3F) and the Carhart 4-Factor Model (1997) (C4F). The models are analysed using a 34 year sample period (1980-2014). The sample data follows the structure explained in Gregory et al (2013) and is compiled of stocks from the London Stock Exchange (LSE). The stocks are grouped into portfolios arranged by market capitalisation, book-to-market ratio, past 2-12 month stock return and past 12 month standard deviation of stock return. Statistical analysis is performed and the suitability of the models is tested using the methods of Black, Jensen \& Scholes (1972), Fama \& MacBeth (1973) and Gibbons, Ross \& Shanken (1989). The results compare descriptive and test statistics across the range of risk factors and test portfolios for the each testing method on all three models. They show that although the UK market has some noticeable factor anomalies, none of the models clearly explains the 1980-2014 stock returns. However, of the three models, C4F shows the highest explanatory power in predicting stock returns.

Over the years there has been significant research around the misspecification of the Capital Asset Pricing Model (CAPM), which challenges the linear relationship between beta and market returns. One of the biggest challenges relates to the “small-firm effect,” which states there are two classifications of stocks (large and small) and that the companies with small-market capitalizations have higher returns. However, the definition of a small-cap is vague and there has been little focus in academia on the stocks in the middle-market capitalization deciles. Despite this, institutional and retail investors created the “mid-cap” category in the early 1990s and, since then, the risk-adjusted returns have been exceptional, relative to small- and large-cap stocks. This study examined mid-cap stocks from an academic perspective and delves into the “mid-cap myth” by evaluating the category over the past 85 years to answer the question around whether mid-caps are superior to other asset class. The results revealed that the highly touted and advertised mid-cap stock performance premium during the 1980-2013 time period was statistically insignificant. Moreover, mid-caps did have superior risk-adjusted returns over the extended time period studied (1928 to 2014); however, these superior returns relative to small-caps were not driven by the uniqueness of the mid-sized companies, but by the underperformance of small-cap stocks, specifically small-cap growth stocks. When studying the behavior or migration of mid-size companies, they do not appear to exhibit unusual behavior relative to companies with smaller market capitalizations, especially in the area of mergers and acquisitions. Thus, the question becomes why small-cap companies underperform relative to their risk level. The answer lies in the inclusion of the NASDAQ stocks to the CRSP database after 1972. This change not only doubled the number of stocks deemed small-caps, but also added a significant number of unprofitable fast-growing companies to the small-cap growth category, specifically in the technology and healthcare industries. The study benefits practitioners by providing insight into the omnipresent claim of mid-cap outperformance from 1980-2014, while also benefiting academia by providing more insight into small-caps’ underperformance during this period and how investigating small-cap growth companies further could add insight into the viability or magnitude of the size and value premium going forward.

By describing investors' decision-making processes and actions, this thesis provides a background to the share prices that millions of people follow closely everyday. It focuses on the reasons for institutional investors' investment actions on the stock market, and in particular the role of financial information about the quoted companies. Interviews and document studies linked to a large number of actual investment actions in eight large Swedish institutional investor organisations constitute the empirical basis of the thesis. Important empirical results concern how action based on fundamental opinions about investment objects is restricted or reinforced by investor contexts and market premises, the role of valuation models and quantitative analysis in comparison with qualitative judgements, and how uncertainty is dealt with during investment decision-making processes. Non-public information played an essential role in forming the fundamental opinions about companies/equities. In addition, this information could help trigger equity investment actions. Several factors, some of them organisational, contributed to time lags between the first impulse and the completed investment transaction.The results also suggest that the institutional investors in this study did not take action independently of other investors. Furthermore, they did not develop their fundamental opinions about investment objects independently of other market participants - to varying extents they adjusted to other market participants' expectations, equity valuation methods and ways of using accounting figures. / Diss.

In the last two decades, duration analysis has been largely applied to fixed - income securities . However, since rising and falling interest rates have been determined to be a major cause of stock price movements, equity duration has received a great deal of attention. The duration of an equity is a measure of its interest rate risk. Duration is the sensitivity of the price of an equity with respect to the interest rate. Convexity is the sensitivity of duration with respect to the interest rate. The analysis revealed that the fractional price change and market risk of equities can be explained by duration and convexity.

And more specifically, in the Brazilian Market. This problem emerged because of recent crisis, which increased the need for regulators to impose more allocation in banking operations. For this reason, the BIS committee, recently introduce a new measure of risk, the Incremental Risk Charge. This measure of risk, is basically a one year value-at-risk, with a 99.9% confidence level. The IRC intends to measure the effects of credit rating migrations and default, which may occur with instruments in the trading book. In this dissertation, the IRC was adapted for the equities case, by not considering the effect of credit rating migrations. For that reason, the more adequate choice of model to evaluate credit risk was the Moody’s KMV, which is based in the Merton model. This model was used to calculate the PD for the issuers used as case tests. After, calculating the issuer’s PD, I simulated the returns with a Monte Carlo after using a PCA. This approach permitted to obtain the correlated returns for simulating the portfolio loss. In our case, since we are dealing with stocks, the LGD was held constant and its value based in the BIS documentation. The obtained results for the adapted IRC were compared with a 252-day VaR, with a 99% confidence level. This permitted to conclude the relevance of the IRC measure, which was in the same scale of a 252-day VaR. Additionally, the adapted IRC was capable to anticipate default events. All result were based in portfolios composed by Ibovespa index stocks. / Esse é um dos primeiros trabalhos a endereçar o problema de avaliar o efeito do default para fins de alocação de capital no trading book em ações listadas. E, mais especificamente, para o mercado brasileiro. Esse problema surgiu em crises mais recentes e que acabaram fazendo com que os reguladores impusessem uma alocação de capital adicional para essas operações. Por essa razão o comitê de Basiléia introduziu uma nova métrica de risco, conhecida como Incremental Risk Charge. Essa medida de risco é basicamente um VaR de um ano com um intervalo de confiança de 99.9%. O IRC visa medir o efeito do default e das migrações de rating, para instrumentos do trading book. Nessa dissertação, o IRC está focado em ações e como consequência, não leva em consideração o efeito da mudança de rating. Além disso, o modelo utilizado para avaliar o risco de crédito para os emissores de ação foi o Moody’s KMV, que é baseado no modelo de Merton. O modelo foi utilizado para calcular a PD dos casos usados como exemplo nessa dissertação. Após calcular a PD, simulei os retornos por Monte Carlo após utilizar um PCA. Essa abordagem permitiu obter os retornos correlacionados para fazer a simulação de perdas do portfolio. Nesse caso, como estamos lidando com ações, o LGD foi mantido constante e o valor utilizado foi baseado nas especificações de basiléia. Os resultados obtidos para o IRC adaptado foram comparados com um VaR de 252 dias e com um intervalo de confiança de 99.9%. Isso permitiu concluir que o IRC é uma métrica de risco relevante e da mesma escala de uma VaR de 252 dias. Adicionalmente, o IRC adaptado foi capaz de antecipar os eventos de default. Todos os resultados foram baseados em portfolios compostos por ações do índice Bovespa.

Thesis advisor: Harold Petersen / Using insights from Hyman Minsky’s Financial Instability Hypothesis (FIH), we develop a theoretical framework for how speculative bubbles may materialize in securities markets. Our model and empirical analysis show that agents place undue emphasis on recent experience of risk and returns when developing future expectations. We use the aggregate investor allocation to equities (aggregate total market capitalization of equities divided by the price of all real liabilities outstanding), Tobin’s Q (the aggregate market price of equities divided by the replacement cost of nonfinancial firms’ assets), Shiller Total Return Cyclically Adjusted Price to Earnings Ratio (TR CAPE), and Shiller Cyclically Adjusted Price to Earnings Ratio (CAPE) as proxy variables for bubbles. We find statistically significant, negative relationships between all four of these proxy variables and two dependent variables, Subsequent Ten-Year Annualized Cumulative Equity Market Returns (Nominal and Real), and also Subsequent 10-year Average Losses, thereby providing evidence against the Efficient Market Hypothesis and suggesting the possibility of speculative bubbles. / Thesis (BS) — Boston College, 2019. / Submitted to: Boston College.

A tese a ser defendida é a de que a autorregulação institucionalmente estruturada e legitimada pela regulação é um eficiente arranjo para tratar as falhas e riscos inerentes ao mercado de bolsa. O trabalho se inicia com a descrição da atual estrutura da autorregulação do mercado de bolsa, destacando seu novo formato institucional decorrente do processo de desmutualização e abertura de capital das entidades administradoras do mercado de bolsa e concluindo pela necessidade de adoção de novas perspectivas sobre o tema que transcendam o aparente antagonismo entre concepções liberais e intervencionistas. A partir dessa premissa, o trabalho apresenta uma visão panorâmica da evolução histórica da autorregulação do mercado de bolsa e considerações sobre os conceitos de autorregulação em outras áreas do conhecimento, a fim de identificar suas variações e seus elementos mais marcantes que constituirão a base a partir da qual serão apresentadas as novas perspectivas de análise do tema. As perspectivas propostas enfocam a natureza jurídica da autorregulação do mercado de bolsa como atividade paraestatal destinada a concretizar o modelo teórico neoclássico de justa formação dos preços segundo a livre atuação das forças de oferta e demanda e, também, melhorar os padrões de conduta praticados no mercado. Para tanto, o trabalho propõe que as decisões tomadas no âmbito da autorregulação se pautem por critérios materiais baseados nas premissas teóricas da concorrência perfeita e na exigência de cumprimento dos deveres derivados da boa-fé objetiva (informação, lealdade e proteção). Por fim, é apresentada uma especulação teórica, preliminar e não definitiva, denominada teoria palco-platéia, que visa situar o desenvolvimento da estrutura de autorregulação do mercado de bolsa como parte de uma questão essencial de interação entre indivíduo e sociedade representada nas diversas situações comunicativas envolvidas nos processos decisórios individuais e coletivos que modelam os padrões de conduta e as instituições públicas e privadas. / The thesis to be defended is that the institutionally structured self-regulation and legitimized by the regulation, is an efficient array to treat flaws and risks inherent of the exchange market. The paper begins with a description of the current self-regulation structure of the exchange market, highlighting its new institutional format, due to the demutualization process and IPO of the entities that manage the exchange market, and concluding with the need of the adoption of new perspectives regarding the subject-matter that transcend the apparent antagonism between liberal and interventionist conception. From this premise, the paper presents an overview of the history of self-regulation of the exchange market and considerations on the concepts of self-regulation in other areas of knowledge, for the purpose of identifying its variations and its most striking elements that will form the basis from which the new perspectives of analysis of the matter will be presented. The proposed views focus on the legal nature of the exchange markets self-regulation as a parastatal activity that seeks to achieve the neoclassic theoretical model of fair pricing, according to the free action of forces of supply and demand, and also improve the conduct standards in the market. Therefore, the paper proposes that decisions made within the self-regulation should be guided by material criteria based on theoretical postulations of perfect competition and in the requirement of the obligations derived from the objective good faith (information, loyalty and protection). Lastly, a preliminary and not final, theoretical speculation is presented, denominated stage-audience theory, which aims to situate the development of the self-regulation structure of the exchange market, as part of an essential matter of interaction between individual and society represented in various communication situations involved in individual and collective decision-making, which shape the standards of conduct, and public and private institutions.
