The first group, consisting of 16 professionals and experts in Investor Relations and the second group, comprised of 11 investment analysts and portfolio managers, were personally interviewed using structured interview, survey-type. The third group of individual investors answered a questionnaire via Internet, totaling 457 valid responses. The findings show that in the perceptions of the three groups, IR adds value to the company. They also pointed out several activities and structures presents in Investor Relations that are considered more relevant in the sense of adding value to the company. Reflecting these activities and structures, it was possible to divide them into five groups: Communication, Activities, Meetings with the Market, Strategy and Metrics of Direct Measurement. The Communication was of higher importance, noting that IR and the company must be transparent, providing the information in a quick, clear, reasoned way, and the IR website and electronic media were identified as the main means. Activities undertaken by IR, shows relevance the contact with foreign investors; the explanation of profit distribution policy; relevant future events, as new investments; the diversification of the shareholder bases; comparative analysis of the sector in which the company operates; and actions to promote the liquidity of shares. Regarding Meetings With the Market, public meetings, individual (with sell side, buy side and institutional) and road shows, were revealed as relevant. About the Strategy in IR, it became clear that it must be drawn on the Executive Board, and the area should be subordinated to the CEO. Finally, Metrics of Direct Measurement point to three main items, namely the amount of "houses" covering the company's stock, the average market valuation compared to the valuation prepared by the company itself, and decrease in volatility of stock price compared with peer companies in the industry. The article seeks to contribute to, in future searches, build more objective and justified proxies for the quality of IR, in an attempt to quantify the value that the IR area adds to the public companies. / A presente dissertação objetivou coletar a percepção de três públicos em específico acerca do entendimento dos mesmos quanto à geração de valor por meio da atividade de Relações com Investidores em companhias abertas brasileiras. O primeiro grupo, formado por 16 profissionais e especialistas em Relações com Investidores, e o segundo grupo, formado por 11 analistas de investimento e gestores de carteiras, foram entrevistados pessoalmente por intermédio de entrevistas estruturadas do tipo survey. O terceiro grupo, dos investidores individuais, respondeu a questionário via internet, totalizando 457 respostas válidas. Os achados mostram que na percepção dos três grupos, RI agrega valor à companhia. Os mesmos ainda apontaram diversas atividades e estruturas presentes em Relações com Investidores que se demonstram mais relevantes no sentido de agregar valor à companhia, bem como aquelas que se demonstram menos relevantes. Espelhando essas atividades ou estruturas, foi possível dividi-las em cinco grupos: Comunicação, Atividades, Reuniões com o Mercado, Estratégia e Métricas Diretas de Mensuração. A Comunicação foi a de maior relevância, apontando que RI e a companhia devam ser transparentes, apresentando as informações de modo rápido, claro e fundamentado, sendo o website de RI e as mídias eletrônicas apontadas como os principais meios. Nas Atividades realizadas por RI tomam relevância o contato e atendimento aos investidores estrangeiros; a política de distribuição de resultados; eventos futuros relevantes, como novos investimentos; a diversificação da base acionária; as análises comparativas do setor em que a companhia atua e; as atividades que favoreçam a liquidez das ações da empresa. Nas Reuniões com o Mercado, as reuniões públicas, individuais (com sell side, buy side e institucionais) e road shows, se evidenciaram como relevantes. Quanto à Estratégia em RI, evidenciou-se que a mesma deve ser traçada na Diretoria Executiva, e a área subordinada ao Presidente Executivo. Por fim, as Métricas Diretas de Mensuração apontam três itens como principais, quais sejam a quantidade de casas cobrindo a ação da empresa, o valuation médio de mercado comparado ao valuation elaborado pela própria companhia e a diminuição na volatilidade no preço da ação comparado com as companhias pares do setor. O estudo busca contribuir para que em futuras pesquisas seja possível a construção de proxies objetivas e mais justificadas para a qualidade do RI, na tentativa de quantificar o valor que a atividade de Relações com Investidores agrega à companhia aberta.

An der Schnittstelle von Quartiers- und Wohnungsmarktforschung wurde im Rahmen dieser Arbeit der Beitrag von Wohnungseigentümern zu einer resilienten Quartiersentwicklung in Berlin untersucht. Die Verknüpfung des Quartiers als Untersuchungsraum mit dem Konzept der Resilienz stellt aus raumwissenschaftlicher Perspektive eine weitgehende Neuerung im akademischen Diskurs dar. Aufgrund der massiven Transformation des deutschen Mietwohnungsmarktes hinsichtlich dessen Eigentümerstruktur seit Ende der 1990er, standen die beiden zentralen Akteure dieses Prozesses - kommunale Wohnungsunternehmen sowie private Finanzinvestoren - im Fokus der Analyse. Der Beitrag der Wohnungseigentümer zu resilienter Quartiersentwicklung wurde sowohl in Hinblick auf deren Bestandsbewirtschaftung als auch hinsichtlich des Engagements in einem weiteren Quartierskontext untersucht und bewertet. Die Ergebnisse der Untersuchung belegen, dass Wohnungseigentümern insgesamt eine sehr bedeutende Rolle für die Resilienz von Quartieren zukommt, da sie diese auf vielfältige Weise beeinflussen - sowohl über ihre Bestandsbewirtschaftung als auch darüber hinaus. Das Engagement im weiteren Quartiersumfeld sowie der daraus resultierende Beitrag zur Quartiersresilienz sind dabei sehr divers, wobei Engagement von den Wohnungseigentümern in verschiedenen Quartieren sehr selektiv erbracht wird. Während in (Groß)Wohnsiedlungen das Engagement recht aktiv war, konnten in Altbauquartieren kaum Aktivitäten der Eigentümer identifiziert werden. Dabei war die Erbringung des Quartiersengagements sowie der Beitrag zur Resilienz von einer Reihe verschiedener Faktoren abhängig (quartiers- und unternehmensspezifische sowie institutionelle). Der Beitrag zur Resilienz von Quartieren konnte für die kommunalen Wohnungsunternehmen im Vergleich zu den privaten Finanzinvestoren insgesamt als positiver charakterisiert werden, wobei eine Pauschalisierung nicht erfolgen kann. So konnte zum einen auch für private Investoren vereinzelt ein durchaus positiver Beitrag zur Quartiersresilienz herausgearbeitet werden, zum anderen wurde auch in einer Reihe von Quartieren ein Ausbleiben des Engagements der kommunalen Wohnungsunternehmen beobachtet. / At the interface of neighborhood and housing market research, the presented study examines the contribution of housing owners to a resilient neighborhood development in Berlin. The link between the neighborhood as an area of research and the concept of resilience is a scientific advancement from a spatial science perspective. Due to the massive transformation of the German rental housing market in terms of its ownership structure since the end of the 1990s, the two central actors of this process, municipal housing companies as well as private financial investors, have been in the center of the analysis. The housing owners’ contribution to resilient neighborhood development was analyzed and assessed both with regard to their stock management and particularly their commitment in the neighborhood. The results of the study reveal that housing owners are of major importance for neighborhood resilience as they influence it in various ways, by their stock management and beyond. The commitment in a broader neighborhood setting as well as the resulting contribution to neighborhood resilience are very diverse. However, housing owners render their activities in various neighborhoods very selectively. While in (large) housing estates the commitment was fairly active, hardly any activities could be identified in old building stock neighborhoods. The performance of neighborhood commitment and the contribution to resilience was dependent on a number of factors (neighborhood and company-specific as well as institutional). The contribution to neighborhood resilience can be characterized as more positively for the municipal housing companies compared to the private investors. A generalization, however, should not be deduced since a positive contribution to neighborhood resilience could be identified for private investors occasionally. Furthermore, an absence of commitment could also be observed for the municipal housing companies in several neighborhoods.

本研究探討外國機構投資人交易行為及其對股票市場的衝擊，參考 Chan and Lokonishok(1995)的交易期間(trading package)觀念，分析外國機構投資人的持股內容及易行為，以了解其選股決策，並驗證其交易行為是否存在正向回應現象；及研究外國機構投資人的交易行為所產生的市場衝擊，以了解外資進出對國內股票市場穩定性的影響，並進一步研究交易完成後的股價回復現象及短期績效表現。 本研究的樣本期間為包括民國 84 年至民國 86 年底，樣本資料包含每日股價資料、每日外國機構投資人的持股明細、以及所有上市個股的財務資料。經實驗後發現，可能是基於風險控管和模擬臺灣股價指數的考量，外國機構投資人傾向買賣大型績優個股；在相同交易行為上，通常有持續十日的現象，且每一次交易的張數並不大。此外，明顯存在著正向回應情形、顯著的市場衝擊和短暫的股價回復現象，如同國外相同的研究結果，本研究亦發現外國機構投資人在買和賣不同的交易行為上，存在著不對稱的影響。 / The study is to Investigate the trading behavior of foreign institutional investors and its market impact on stock prices. The purposes of the study are as follows: First, to analyze the holding characteristics and trading behavior of foreign institutional investors in order to understand their stocks selection decisions and test if positive feedback behavior exists. Second, to analyze the market impacts on Taiwan stock market stability. Finally, after finishing each trading behavior, to observe the trend of stock prices in order to test if price reversion exists and how their short-term performance are. Form empirical studies, foreign institutional investors tend to hold stocks of large-size firms probably because of controlling investment risk and simulation Taiwan stock index. Besides, analyzing their trading activities, positive feedback bahavior, market impacts and price reversion really exist and are significant. According to our study, we found that buying and selling activities have asymmetric impact on stock prices. The conclusion is the same as foreign studies.

本文主要研究外資、投信及自營商這三大法人是否有「處分效果」及「過度自信」行為上的偏誤，並想要進一步探討投資人是否可以透過觀察三大法人在不同景氣狀態下的異常行為建立投資組合以獲得顯著的超額報酬，故利用Weber and Camerer（1998）所提的處分係數（The disposition coefficient）來表示處分效果及黃坤興（2006）提出的修正過度自信係數（The overconfidence coefficient）代表過度自信現象，並採用二情境轉換模型，以馬可夫鏈描述情境轉換行為，觀察三大法人在2005年至2013年台灣股票市場上的行為。 研究結果發現在不同的景氣狀態下三大法人會有不同的異常行為產生，在景氣繁榮期外資有處分效果而無過度自信，投信則無異常行為，而自營商沒有處分效果而有過度自信傾向；在景氣低迷時期外資有處分效果而無過度自信現象，投信沒有處分效果而有過度自信，自營商則是同時有處分效果與過度自信，而投資人可以在三大法人有異常行為時，利用放空高係數資產及買入低係數資產獲取正報酬。

Dans une perspective pratique et axée sur le droit transactionnel, l'auteur dresse un portrait global du régime juridique s'appliquant aux actionnaires minoritaires de sociétés par actions publiques canadiennes. Pour ce faire, il aborde, dans un premier temps, les divers mécanismes transactionnels utilisés par les sociétés désirant procéder à une opération de changement de contrôle. Dans un deuxième temps, il enchaîne en expliquant les enjeux entourant la protection des actionnaires minoritaires pour, par la suite, décrire les obligations afférentes au Règlement Q-27. Finalement, il propose une analyse du traitement des porteurs minoritaires à la lumière, d'une part, de la gouvernance d'entreprise et, d'autre part, de l'activisme des investisseurs institutionnels. / In a practical perspective based on transactionallaw, the author shows a global portrait of the legal regime applicable ta minority shareholders of Canadian publicly listed corporations.

中國加入WTO之後，大陸經濟體制轉型。從早期的計劃經濟到現在的市場經濟。投資政策也趨向「引進來，走出去」，此外，有鑑於大陸具有廉價的勞工和市場潛力，外資紛紛從所謂綠地投資或藉由合格境外投資者等間接投資方式轉為合併或收購為主的直接投資為取向。然而，面對上市公司因為涉及中國大陸特有的「股權分置」現象，使外資於併購上有一定困難度。再者，中國大陸特有的「民族情感」因素，使行政機關常常藉由「國家安全」等不確定法律概念而否准外資併購。 本文主要針對外資併購上市公司經常適用之法令作整合及研究，並論及外資併購上常運用之契約條款進行分析。此外，針對外資併購常遇到之問題提出淺見並針對外資併購中債權人及中小股東之保護提出論述，以供外資於併購中如何在外資獲利及中小股東權益保障獲得平衡點。 / Since China has become the members of WTO, the economic structure has transformed. From the early plan structure becomes to market structure. The policy of investments is tend to be “attract in and walk out”, besides, because of the cheaper workers and marketing potential of China, the foreign investor’s investment policy is going to be from the indirect investment of green island investment or QFII to the direct investment of Merger & Acquisition. However, in face of the especially system phenomenon of “delaminate of stock rights”, makes the merger& acquisition by foreign investors difficultly. Moreover, because of the especially factor of “the nationality of friendship”, makes the administrative organizations often refuse the permition of foreign investors by “national security”. In this essay, be focus on the research the merger& acquisition by foreign investors in common use of the authority laws and decrees, and analyzing the common use of the contracts articles. Besides, to be aimed at the problems of the merger& acquisition by foreign investors and the protection of shareholders and creditors, I try to supply some suggestions in order to make the balance of the merger& acquisition by foreign investors and the protection of shareholders and creditors.

本篇研究試圖探討半導體產業供應鏈上游的IC設計業者召開法人說明會後，基於我國半導體產業供應鏈緊密連結之特性，同屬半導體供應鏈的其他中、下游製造和封測廠之機構投資人的交易行為是否將受到IC設計業者宣告之法人說明會資訊影響，亦即證明法人說明會資訊在半導體供應鏈中是否具有垂直資訊移轉效果。實證結果發現在法人說明會召開訊息首次見報日時，供應鏈上游公司之法人說明會訊息確實會影響其中、下游公司之機構投資人的持股變化，於宣告好(壞)消息時買進(賣出)，顯示機構投資人藉由其專業團隊和私有資訊能早一般大眾提前調整其交易策略，而此資訊移轉效果也會隨著公司在供應鏈上之距離而逐漸稀釋。此外，結果亦顯示外資由於地緣限制，相較於投信和自營商更會倚賴法人說明會宣告之資訊調整其持股策略，於宣告好(壞)消息時買進(賣出)。 / This research examine the conference call which hold by the IC design companies will transfer useful information to the institutional investors of IC manufacturing and packaging companies in the supply chain downstream. I am interested in if there is a vertical information transfer in the semi-conduct industry. The empirical results show that the conference call information is significantly influence the holding percentage of the institutional investors of the downstream supply chain companies after the information of conference call first reported in the newspapers. The institutional investors will increase the holding percentage after the good news released and vice versa. It is showed that the institutional investors can gather more information before the conference call and adjust their invest strategy in advance. Furthermore, this vertical information transfer effect will dilute by degrees as distance increases. Lastly, the result also shows that the foreign institutional investors more rely on the information released from the conference call to adjust their invest strategy than native institutional investors.

I tidigare studier har det framkommit att amerikanska företag manipulerar sina finansiella räkenskaper inför en nyemission med hjälp av Earnings Management genom oförklarliga periodiseringar. Detta görs i syfte att reflektera en bättre bild av företagets finansiella ställning gentemot hur det i verkligheten ser ut. Företeelsen tillämpas med avsikt att erhålla ett större finansiellt riskkapital då företaget utfärdar nyemission. Denna studie undersöker om svenska företag agerar likt amerikanska företag vid en nyemission och därför är syftet i studien att undersöka om svenska företag tillämpar Earnings Management genom oförklarliga periodiseringar vid perioden då de utfärdar nyemission. Svenska företag har varit av intresse i följande studie då svenska företag verkar under ett annorlunda redovisnings- och skattesystem än amerikanska företag gör, varpå vi vill testa om teorin Earnings Management genom oförklarliga periodiseringar är tillämpbar på även svenska företag, trots de skillnader som föreligger mellan ländernas lagsystem. Studien har genomförts med hjälp av en kvantitativ metod som vi presenterat med hjälp av en deskriptiv statistisk analys. De resultat som framkommit i studien är att även svenska, såväl som amerikanska, företag tillämpar Earnings Management genom oförklarliga periodiseringar vid de kvartal då ska utfärda nyemission, trots de olikheter i redovisnings- och skattesystem som råder länderna emellan. Förutom detta visar studien på att svenska företag även tillämpar en extrem form av Earnings Management samt att olika branscher tillämpar Earnings Management genom oförklarliga periodiseringar i olika grad då de ska utfärda nyemission. De resultat som framkommer i följande studie visar att det är av stor betydelse att investerare har en medvetenhet om att Earnings Management genom oförklarliga periodiseringar förekommer när svenska företag ska utfärda nyemission. Detta är av vikt då tidigare studier har påvisat att många investerare som förvärvat aktier i företagen som tillämpat Earnings Management genom oförklarliga periodiseringar har känt en besvikelse samt upplevt att de blivit missledda av företagens publicerade finansiella rapporter efter nyemissionen. Besvikelsen grundar sig i att det rapporterade resultatet vanligtvis kraftigt sjunker kvartalen efter nyemission då företagen tillämpat Earnings management genom oförklarliga periodiseringar. / In previous studies, it has been found that US companies manipulate their financial statements before issuing Seasoned Equity Offerings (SEO) using Accrual-based Earnings Management. This is done by the company in order to reflect a better financial position compared to their true underlying financial performance. Accrual-based Earnings Management is applied with the intention of obtaining larger financial capital when issuing SEOs. This study examines whether Swedish companies, consistent with US companies, apply the phenomenon in a similar way while issuing SEOs and the purpose of our study is therefore to investigate whether Swedish companies apply Accrual-based Earnings Management in the period they issue SEOs. Swedish companies have been of interest in the following study, as Swedish companies operate under a different accounting and tax law compared to that of American companies. As a result, we want to test the theory of Accrual-based Earnings Management to see if it is applicable to Swedish companies, despite the differences in tax law that exists between the countries. The study has been conducted using a quantitative methodology which has been presented through a descriptive statistical analysis. Our results imply that Swedish- as well as American companies, apply Accrual-based Earnings Management in the period they issue SEOs. This is found despite differences in accounting and tax law between the two countries. In addition to this, the study also shows that Swedish companies apply an extreme form of Accrual-based Earnings Management, and that it exist industrial differences in the level of Accrual-based Earnings Management that is applied when issuing SEOs. The results found in the following study show that it is of the utmost importance that investors have an awareness regarding Accrual-based Earnings Management and that it occurs when Swedish companies issue a SEO. This is important as previous studies have shown that many investors who acquired shares in the companies who applied Accrual-based Earnings Management when issuing SEOs, have felt disappointed and have found that they have been misled by the companies published financial reports following the SEO. The disappointment is based on the fact that as companies apply Accrual-based Earnings Management, the companies reported earnings usually fall in the period after issuing a SEO.

Muitos casos recentes chamam a atenção para este assunto, porém, um em especial, o esquema de corrupção envolvendo práticas ilegais, como pagamentos de propina dentro da Petrobras e outras empresas brasileiras, descoberto após a deflagração da “Operação Lava-Jato”, conduzida pela Polícia Federal e pelo Ministério Público. Após a descoberta desse esquema, muitos envolvidos foram presos, alguns já investigados e condenados pela justiça brasileira. Porém, além dos desdobramentos na esfera criminal de pessoa-física, as práticas de corrupção tiveram outros desdobramentos jurídicos e financeiros no âmbito empresarial, principalmente relacionados a ações judiciais propostas por acionistas da empresa que alegam ter sofrido perdas em seus investimentos. Nesse sentido, dadas as questões financeiras e legais enfrentadas pela Petrobras e demais empresas brasileiras, propomos, através desta pesquisa, determinar como a detecção da fraude impacta no valor das empresas. Para atingir o objetivo final desta pesquisa, usei a metodologia de estudo do evento, proposta por MacKinlay (1997). A amostra deste estudo incluiu as cinco empresas brasileiras listadas na “New York Securities Exchange” (NYSE), que estavam sujeitas a ações de classe nos EUA, até o final de 2016. Os resultados gerais dos testes suportam a hipótese de que a fraude, uma vez divulgada ao mercado, gera reações negativas nos preços das ações, em linha com a literatura existente sobre a influência da fraude no valor das empresas e com a Teoria da Eficiência de Mercado. Nesse sentido, este estudo é capaz de contribuir de maneira significativa para aprofundar a discussão acadêmica relacionada à fraude no Brasil e incentivar as empresas brasileiras de capital aberto a se preocuparem cada vez mais com suas práticas de conformidade e combate à corrupção e se prevenirem em relação aos seus possíveis riscos, desdobramentos e impactos jurídico-financeiros. Além disso, esta pesquisa serve de insumo, não apenas para a gestão de patrimônio dos investidores dos EUA, mas também como um incentivo para aumentar o poder de barganha dos investidores pessoa-física no Brasil / It is of great importance, either for academia or society as a whole, the issue of fraud, a recurring problem that affects companies and governments around the world. Many recent cases draw attention to this issue, but one in particular: the corruption scheme involving illegal practices such as bribery payments inside Petrobras and other Brazilian firms, discovered after the outbreak of the so-called "Operação Lava-Jato" and “Operação Zelotes”, conducted by the Brazilian Federal Police and Federal Public Prosecutor. After the scheme became public, over a hundred people were arrested and many already investigated and condemned by the Brazilian justice, including some of the firm’s former and current employees. In addition to the developments on individual employee´s criminal sphere, once detected, the abovementioned corrupt practices have caused other legal and financial impacts to the firms, mainly related to lawsuits filled by shareholders who claim to have suffered losses on their investments. In this sense, given the financial and legal issues faced by Petrobras and the other Brazilian firms, we propose through this research to determine how disclosed fraud could have an impact on the value of firms. In order to achieve its final goals, this research uses the event study methodology, proposed by MacKinlay (1997). Firm sample includes the five Brazilian firms listed in the New York Securities Exchange (NYSE), which were subject to securities class action lawsuits in the US, as of the end of 2016. Overall test results support the hypothesis that fraud, once disclosed to the market, provides negative stock price reactions, in line with the existing literature on the influence of fraud on firms’ valuation and the Market Efficiency Theory. In this sense, this study is able to provide significant contribution to deepen the academic discussion related to fraud in Brazil and encourage Brazilian firms to increase their concerns about anticorruption and compliance practices and prevent themselves in relation to eventual legal and financial impacts of fraud. In addition, this research contributes, not only to U.S investors wealth management, but also as an incentive to increase the bargain power of individual investors in Brazil
