The application of the internet technology on securities markets has been increasing over recent years, so is the influence it has caused on the way the stock market is operated. There is no doubt that internet technology is changing the access between investors and issuing firms, as well as the access between investors and exchanges. How would this affect the stock market microstructure? Little study has been done thus far in this regard, and, as far as we know, none has looked into the issue of IPOs on internet and its related impact on IPO returns. In addition to the impact on the primary market, internet tradings also have immense impact on the underlying performance of the secondary market. The purposes of this study are mainly twofold:(1) To explore the related issues in IPOs or DPOs on internet, e.g., the disclosure requirements, the restriction of investors, and the effect it has on IPO discounts,(2) To empirically test how the internet trading affects the daily and intraday performance (i.e., liquidity, volatility and efficiency) of the market.This is the first study attempting to examine the pricing issue of IPOs on the internet. We hope to compare the returns of initial public offerings on the internet with those of the traditional IPOs and analyze the differences, if any. In addition to provide useful analyses to the security authority on DPOs or IPOs on internet, the result of this study should contribute to our understanding of the market microstructure.

However, state-owned enterprises have a peculiarity because they are controlled by the government and, consequently, used for political purposes. The objective of the research is to analyze whether, at the time of the announcement of the appointment of presidents of state-owned companies that perform a relevant function in the activity level of the companies (Petrobrás and Banco do Brasil), there is a statistically significant reaction in the return of the common shares. To measure the result, he used the statistical methodology of event study. After analyzing the appointments individually, it was found inconclusive to say that there is a statistically significant reaction of the financial market to the announcement of the appointments studied in the first term of the governments of the Presidents of the Republic (Fernando Henrique Cardoso, Luis Inácio Lula da Silva and Dilma Rousseff, succeeded by Michel Temer) / De acordo com a literatura existente, a divulgação de fatos relevantes ao mercado representa um importante instrumento na avaliação dos investidores para formação do preço dos papéis negociados em bolsa. Porém, as empresas estatais possuem uma peculiaridade por serem controladas pelo governo e, consequentemente, serem utilizadas para fins políticos. O objetivo da pesquisa é analisar se, no momento do anúncio da nomeação de presidentes de empresas estatais que exercem função relevante no nível de atividade das empresas (Petrobrás e Banco do Brasil), ocorre reação estatisticamente significativa no retorno das ações ordinárias. Para medir o resultado, utilizou-se a metodologia estatística de estudo de eventos. Após analisar as nomeações individualmente, verificou-se que é inconclusivo dizer que há reação estatisticamente significativa do mercado financeiro ao anúncio das nomeações estudadas no primeiro mandato dos governos dos Presidentes da República (Fernando Henrique Cardoso, Luís Inácio Lula da Silva e Dilma Rousseff, sucedida por Michel Temer)

This thesis examines how the American economy is affected by the market sentiment that arises from the news about actions and decisions of the American President Donald Trump. The news articles are obtained from Reuters for the period between the 1st of May and the 30th of November 2018, based on which a sentiment variable is created using natural language processing methods. Firstly, the impact of Trump sentiment on the returns on the S&P 500 Index is examined. The results show a positive and statistically significant impact of sentiment from the previous day on today's S&P 500 Index return. A statisti­ cally significant effect of the sentiment from a week ago is also found, however, this effect is negative. This result indicates that there is an initial overreaction to the new information, followed by subsequent market correction to the mean. Such result is consistent with the findings of the field of behavioural finance, which incorporates the idea that investor psychology is involved in investment decision making. Secondly, the impact of the news sentiment on the performance of individual sectors of the American economy, as measured by the returns on S&P 500 sector indices, is analysed. A statistically significant effect of sentiment on sector index return is found in the case of Consumer...

<p>Problem:   What are the most useful techniques to indicate the stocks that will outperform the market 12 month post the recession period?  Purpose:  The purpose is to find out which method(s): P/B, EV/EBIT, level of debt and so on, will offer investors the highest returns on the investments post the recession period based on the example of the IT crisis of 2000/2001.  Method:  Quantitative study, covering the Swedish OMX Index from 2001 until December 2002.  Conclusions:  Three variables should be reconsidered when making an investment decision post the recession period. These variables were earlier 12 months returns, dividend yield and P/E ratios. However, it is crucial to understand that these three tools should not be viewed all together.</p><p> </p>

Cette thèse étudie le lien entre les caractéristiques des conseils d’administration des banques acquéreuseset la performance boursière à court terme de celles-ci, analysée grâce à la méthodologie d’étude d’événement.L’objectif étant de vérifier si la structure des conseils contribue à l’atténuation des conflits d’intérêts àl’occasion des opérations de fusions-acquisitions (F&A) et crée, par conséquent, de la valeur. Deux effets ontété mis en avant. Le premier suppose une influence directe de chacune des caractéristiques du conseil sur lesrendements anormaux de l’acquéreur ; tandis que le second, introduit l’effet médiateur de la prime de contrôlepayée, en considérant que la structure du conseil influence le pouvoir de négociation de ses membres et leurengagement dans l’intérêt des actionnaires. Pour ces deux effets, nous contrôlons certains déterminants de laperformance relatifs à la transaction et aux banques impliquées.Nos résultats indiquent que les marchés financiers ont des attentes vis-à-vis des conseils lors de cesopérations, car nous avons relevé une incidence favorable sur les rendements anormaux de la présence depersonnalités extérieures en proportion significative au conseil de l’acquéreur et de l’absence de dualité dedirection dans celui-ci. Par ailleurs, en contrôlant le choix de la méthode de paiement, nous avons égalementrelevé que l’utilisation du cash est fortement associé à des rendements positifs pour l’acquéreur. / This thesis analyzes the relationship between Board characteristics of acquiring Banks and short termStock Market reactions, measured with the Event Study Methodology. We examine if Board structure helps tolower conflict of interests during Mergers and Acquisitions, and creates Shareholder value. Two effects areanalysed. The first one supposes a direct influence of Board characteristics on the acquirer’s abnormal returns.The second one introduces a mediating effect of the premium, considering that Board structure affects itsmembers’ commitment. For both effects, we control some performance determinants relative to transactionand involved banks.Our results indicate that Financial Markets expect that Boards play an important role in acquisitions. Wefind a favourable impact of outside dominated Boards and the absence of duality on the acquirer's abnormalreturns. In addition, by controlling the method of payment, we obtain a significant and positive correlationbetween use of cash and acquirer's returns.
