Bakgrund: Tidigare forskning har visat att insynspersoner tenderar att överavkasta på investeringar i eget bolag. Det råder dock delade meningar kring varför insynspersoner tenderar att överavkasta. Vid genomgång av tidigare studier påträffades ingen kvalitativ studie, varav vi ansåg det vara av intresse att studera fenomenet genom intervjuer med insynspersoner. Syfte: Uppsatsen syftar till att studera och kartlägga motiven bakom insynspersoners köp- och säljtransaktioner i eget bolag. Med hjälp av tidigare forskning samt en ny infallsvinkel i form av teorier inom behavioural finance analyseras varför insynspersoner tenderar att uppnå överavkastning på investeringar i eget bolag. Genomförande: Studien har genomförts med utgångspunkt i åtta intervjuer med insynspersoner. Resultat från tidigare studier på området låg till grund för vilken information vi med intervjuerna ville uppnå djupare förståelse kring. Den insamlade empirin har analyserats utifrån empirisk forskning och teorier inom behavioural finance. Slutsats: I studien presenteras en ny hypotes vilken förklarar insynspersoners överavkastning som en följd av befintlig lagstiftning. Vi menar att lagstiftningen förhindrar ofördelaktiga handlingar, vilket i sin tur leder till att insynspersoner i större utsträckning än övriga investerare tenderar att undvika psykologiska fallgropar. / Background: Previous researches have shown that insiders tend to achieve excess returns on investments in own companies. However there are still disagreements regarding possible explanations for this phenomenon. In our review of previous research we did not discover any qualitative studies in the area and therefore we found it interesting to study the phenomenon by interviews with insiders. Aim: The purpose of this paper is to study and identify the motives behind insider buy and sell transactions in own companies. By using previous research and also create a new approach through apply theories within behavioural finance we aim to analyze why insiders tend to achieve excess returns on investments in own companies. Completion: This study was conducted based on eight interviews with insiders. Results from previous research formed the basis of what information we wanted to achieve a deeper understanding of through our interviews. The empirical data has been analyzed based on empirical research in the area and theories within behavioural finance. Conclusion: In this paper a new hypothesis is formed which try to explain insiders excess return as an indirect result from the regulations of insider transactions. Thanks to the regulations, impulsive actions are prevented and insiders thereby tend to avoid psychological pitfalls to a greater extent than other investors.

Insider trading is one of the practices that (directly or indirectly) lead to a host of problems for example inaccurate stock market prices, high inflation, reduced public investor confidence, misrepresentation and non disclosure of material facts relating to securities and financial instruments. Again it reduces efficiency in the affected companies and eventually leads to economic underperformance. The researcher observed that the South African insider trading regulatory framework has some gaps and flaws which need to be adequately addressed to ensure efficient and stable financial markets. Therefore, the aim of this research is to provide a clear roadmap for an effective, efficient, adequate and internationally competitive insider trading regulatory framework in South Africa. In order to achieve the above stated aim, the historical development of the regulation insider trading is critically analyzed. The effectiveness and adequacy of the Insider Trading Act, 135 of 1998 is also discussed. Furthermore, the prohibition of insider trading under Securities Services Act, 36 of 2004 is explored and analyzed to investigate its adequacy. The role of the Financial Services Board, the Courts and the Directorate for Market Abuse is also scrutinized extensively. Moreover, a comparative analysis is undertaken of the regulation of insider trading in other jurisdictions of United States of America, Canada and Australia. This is done to investigate any lessons that can be learnt or adopted from these jurisdictions. The researcher strongly contends that having the best insider trading laws on paper alone will not cure the insider trading problem. What is required are adequate laws that are enforced effectively in South African courts. Therefore an adequate insider trading regulatory framework must be put in place to improve the efficiency of South African financial markets, to maintain a stable economy, combat misrepresentation and non disclosure of material facts in transactions relating to securities. The researcher has attempted to state the law as at 31 August 2007.

Insider threat continues to pose a risk to organizations, and in some cases, the country at large. Data breach events continue to show the insider threat risk has not subsided. This qualitative case study sought to explore the data security management strategies used by database and system administrators to prevent data breaches by malicious insiders. The study population consisted of database administrators and system administrators from a government contracting agency in the northeastern region of the United States. The general systems theory, developed by Von Bertalanffy, was used as the conceptual framework for the research study. The data collection process involved interviewing database and system administrators (n = 8), organizational documents and processes (n = 6), and direct observation of a training meeting (n = 3). By using methodological triangulation and by member checking with interviews and direct observation, efforts were taken to enhance the validity of the findings of this study. Through thematic analysis, 4 major themes emerged from the study: enforcement of organizational security policy through training, use of multifaceted identity and access management techniques, use of security frameworks, and use of strong technical control operations mechanisms. The findings of this study may benefit database and system administrators by enhancing their data security management strategies to prevent data breaches by malicious insiders. Enhanced data security management strategies may contribute to social change by protecting organizational and customer data from malicious insiders that could potentially lead to espionage, identity theft, trade secrets exposure, and cyber extortion.

De nombreux travaux marketing décryptent l’effet des marques sur le consommateur, mais rares sont ceux qui étudient leur rôle à l’interne des organisations. Cette recherche-insider s’appuie de façon originale sur les travaux en théorie des organisations, et précisément sur ceux du courant des « Brands at Work » qui aborde la marque comme une nouvelle forme de contrôle au sein des organisations, pouvant affecter l’identité des employés. Cette recherche qualitative (59 entretiens longs) étudie empiriquement le rôle de la marque dans les processus de régulation identitaire (RI) des managers, à la fois producteurs et récepteurs de son discours, dans le cas spécifique de l’industrie du luxe. Nos résultats montrent l’existence d’un langage-type managérial inspiré du discours marketing, visant à masquer des pratiques de management et de production, le luxe pouvant être théorisé comme une « storytelling industry ». Nous caractérisons comment le management utilise la marque comme outil de RI ; la marque pouvant soutenir les pratiques de RI - cas que nous labellisons « la marque fait management » - ou cristalliser les tensions, brouiller les pratiques; « défaire management ». / While brands are traditional topics for the marketing research, they do not retain much attention from organization studies. This thesis originally draws upon the recent « Brand at Work » trend that considers brands as an internal organizational resource affecting identity, a tool for organizational control. Drawing on an insider-research in the luxury industry and on rich empirical material (59 interviews), we show the existence of an archetypal managerial discourse, deeply infused by the marketing discourse, brand being both used as a management tool, and a way to disguise the reality of practices; turning the luxury into a “storytelling industry”. Looking at managers, both producers and receivers of the brand message, we reveal the role of the brand in their identity regulation (IR) processes. We found that the brand can either support their IR practices, managers willingly buying into the brand, or crystallize tensions, corrode IR and act as a dis-connecting mechanism between identity (re)formation and regulation processes. We show the centrality of brand in managers’ identity regulation processes.

Cyber insider threat is one of the most difficult risks to mitigate in organizations. However, innovative validated visualizations for cyber analysts to better decipher and react to detected anomalies has not been reported in literature or in industry. Attacks caused by malicious insiders can cause millions of dollars in losses to an organization. Though there have been advances in Intrusion Detection Systems (IDSs) over the last three decades, traditional IDSs do not specialize in anomaly identification caused by insiders. There is also a profuse amount of data being presented to cyber analysts when deciphering big data and reacting to data breach incidents using complex information systems. Information visualization is pertinent to the identification and mitigation of malicious cyber insider threats. The main goal of this study was to develop and validate, using Subject Matter Experts (SME), an executive insider threat dashboard visualization prototype. Using the developed prototype, an experimental study was conducted, which aimed to assess the perceived effectiveness in enhancing the analysts’ interface when complex data correlations are presented to mitigate malicious insiders cyber threats. Dashboard-based visualization techniques could be used to give full visibility of network progress and problems in real-time, especially within complex and stressful environments. For instance, in an Emergency Room (ER), there are four main vital signs used for urgent patient triage. Cybersecurity vital signs can give cyber analysts clear focal points during high severity issues. Pilots must expeditiously reference the Heads Up Display (HUD), which presents only key indicators to make critical decisions during unwarranted deviations or an immediate threat. Current dashboard-based visualization techniques have yet to be fully validated within the field of cybersecurity. This study developed a visualization prototype based on SME input utilizing the Delphi method. SMEs validated the perceived effectiveness of several different types of the developed visualization dashboard. Quantitative analysis of SME’s perceived effectiveness via self-reported value and satisfaction data as well as qualitative analysis of feedback provided during the experiments using the prototype developed were performed. This study identified critical cyber visualization variables and identified visualization techniques. The identifications were then used to develop QUICK.v™ a prototype to be used when mitigating potentially malicious cyber insider threats. The perceived effectiveness of QUICK.v™ was then validated. Insights from this study can aid organizations in enhancing cybersecurity dashboard visualizations by depicting only critical cybersecurity vital signs.

Bakgrund Coronapandemin har haft en global påverkan på den finansiella marknaden, inte minst på Stockholmsbörsen, som rasade 11,1 procent under en dag. När det råder en osäkerhet på marknaden ökar informationsasymmetrin mellan marknadsaktörer. Tidigare studier har visat att insiders kunde uppnå överavkastning utifrån insiderinformation under kriser. Insiderhandel kan vanligen tolkas som något olagligt och trots regleringar existerar det fortfarande på marknaden. Antalet misstänkta insiderbrott ökade från 199 till 368 under tidsperioden 2015-2017. Syfte Syftet med denna studie är att analysera om det uppstår överavkastning på Stockholmsbörsen när en vd förvärvar aktier i det egna bolaget genom att studera ett urval av bolag under coronapandemin. Vidare kommer studien även att analysera huruvida det förekommer skillnader i överavkastningen beroende på transaktionsstorlek och storleken på företaget. Metod Studien tillämpar en kvantitativ forskning genom en eventstudie. Vidare tillämpas en deduktiv ansats med sekundärdata från Finansinspektionen och Nasdaq. För att beräkna eventuell överavkastning har den justerade marknadsmodellen använts. Statistiska tester har genomförts i SPSS för att tolka och analysera studiens resultat samt huruvida transaktionsstorlek och företagsstorlek påverkar eventuell överavkastning.Slutsats Utifrån studiens resultat återfinns inga signifikanta resultat under tidsperioden 2019-2021 som visar att det uppstått överavkastning i samband med att företagets vd köpt aktier i bolaget. Studien stödjer inte heller att det återfinns ett samband mellan insiderns avkastning och transaktionsstorlek eller företagsstorlek. Resultatet indikerar på att Stockholmsbörsen kan antas vara effektiv under den studerade perioden / Background: The corona pandemic has had a global impact on the financial market, not least on the Stockholm Stock Exchange, which fell 11.1 percent in one day. When there is uncertainty in the market, the information asymmetry increases. Previous studies have proven that insiders could achieve excess returns based on insider information during crises. Insider trading can usually be interpreted as something illegal and despite regulations, it still exists. The amount of suspected insider crimes increased from 199 to 368 during the period 2015-2017.Purpose: The purpose of this study is to analyze whether there is an excess return on the Stockholm Stock Exchange when a CEO acquires shares in his own company by studying a selection of companies during the corona pandemic. Furthermore, the study will also analyze whether there are differences in the excess return depending on the transaction size and the size of the company.Methodology: The study applies a quantitative research strategy through an event study. A deductive approach is applied with secondary data from Finansinspektionen and Nasdaq OMX Nordic. To calculate excess return, the adjusted market model has been used. Statistical tests have been performed in SPSS to analyze and interpret the results of the study and whether transaction size and company size affect any excess return. Conclusions. Based on the results of the study, there are no significant results during the period 2019-2021 which show that there has been an excess return in connection with the company's CEO buying shares in the company. The study also does not support that there is a connection between the insider's return and transaction size or company size. The result takes us further to the fact that the Stockholm Stock Exchange can be assumed to be efficient during the period studied

Insider trading on the JSE can be linked, directly or indirectly, to the reputation of the South African financial market. The regulation thereof is essential and a non-negotiable requirement for the successful attraction and retention of investment flows. Inadequacies associated with the regulatory framework regulating insider trading, the onus of proof in a criminal trial and the lack of civil remedies associated with insider trading as a form of market abuse, motivates a critical analysis into the regulatory framework on insider trading in South Africa. The aim of this study is therefore to identify international best practice principles to fill the gap in South Africa’s regulatory framework. This gap relates to the practical application and execution of legislative and other instruments in order to combat insider trading as a form of market abuse. A further aim focuses on the simultaneous development of the legislation relating to financial markets in conjunction with developments in the economy. A final aim is to determine whether and how South Africa can improve its current legislative dispensation on insider trading. In order to arrive at the aim of the study the historical development on the regulation of insider trading is discussed. A critical analysis of the relevant insider trading sections in the Securities Services Act 36 of 2004 is compared with the corresponding sections of the Financial Markets Act 19 of 2012. A discussion on the roles, duties and authority of the Financial Services Board, the Directorate of Market Abuse and the Enforcement Committee will assist in analysing these organisations' contribution in regulating insider trading in South Africa. A look into the application of other regulatory instruments including the JSE’s Code of Conduct is required. In order to determine whether and how South Africa can improve its current legislative dispensation on insider trading, a comparative study is conducted with Hong Kong. It is submitted that the South African regulatory framework on insider trading has to be revised in order to align with international best practice principles and to promote transparency of the JSE, promote investor confidence and ensure justice for all. / LLM (Import and Export Law), North-West University, Potchefstroom Campus, 2015

It is unfair to the investing public and detrimental to the interests of the security markets for a person to trade on the basis of inside information. In this short dissertation, the laws regulating insider trading in South Africa prior to the current legislative provisions are briefly discussed. It is found that the old provisions were inadequate in deterring and punishing insider trading activities. The current legislative provisions are analysed in detail. It becomes clear that whilst the current provisions are a substantial improvement on their predecessor, certain aspects need to be reconsidered. These include the widening of their scope to include trading in all kinds of derivatives; the reformulation of the statutory civil action and the empowerment of the securities regulation panel to bring a civil action against insider traders. / Private Law / LL.M.
