The Relationship

In the present paper, the relationship between corporate governance mechanisms of a firm and stock returns triggered by insider trading announcements is examined. Event study methodology has been used to evaluate the influence of 636 insider trading announcements performed by executives of 14 listed firms in the Athens Stock Exchange, that operate in the technology sector, during the period 2007-2013. The relationship between cumulative abnormal stock returns (CARs), caused by the announcements, and corporate governance characteristics, was then examined for different time windows, both for sales and purchases of stocks by insiders. Our findings suggest that insider trading, especially in purchases, performed by CEOs and members of the Boards of Directors, has a significant effect on stock returns in the long run. More specifically concentrated ownership structures and control were found to have a negative/positive effect in abnormal stock returns of the firms only in long-term periods of time following the announcement of purchases/sales.

The Relationship

This study examines the impact of intellectual capital and corporate governance mechanism on banks’ performance both directly and also moderated effect. We used banks that were listed in the Indonesia Stock Exchange. The bank’s performance was measured by risk-based bank rating while intellectual capital was measured by the coefficient of VAICTM (Pulic, 1998). The corporate governance mechanism was measured based on the size of boards of directors, the composition of independent director, CEO remuneration, managerial ownership, the effectiveness of audit committee and ownership concentration. The result of the study shows that banks’ performance was positively influenced by intellectual capital. However, corporate governance mechanism did not influence the banks’ performance, while the moderation effect of corporate governance mechanism on the relationship between intellectual capital and banks’ performance was not confirmed.

The Relationship

In this paper, our purpose is to examine the relationship between the role of Internal Audit (IA), Corporate Governance (CG) and the Audit Committee (AC) in the recent financial crisis in Greece and to investigate the contribution of IA to CG structures as well as its possible, the IA’s role during the financial crisis in Greece. Moreover, little research has been conducted based on the relationship between corporate governance and internal audit during the financial crisis in case of Greece. For this reason, we conducted a survey, using questionnaires, which were sent to the listed companies of the Athens Stock Market. Out of a total of 192 listed companies on the Athens Stock Exchange, the relevant questionnaires were sent to 100 companies. Those companies were selected firstly based on their total turnover and secondly due to the availability of information from company websites such as employees’ numbers and Internal Audit Department Structures. Our conclusion was that Internal Audit adds value to the organization and it can also help the senior management towards the accomplishment of the organizational goals.

Regulatory Reforms

This study provides evidence on the value relevance of corporate governance mechanisms in a developing stock exchange. It empirically investigates the effect of corporate governance mechanisms prescribed by the corporate governance law (L.3016/2002) on abnormal stock returns for firms listed in the Athens Stock Exchange (ASE). The first corporate governance law in Greece aims to improve the existing corporate governance framework. However, stock prices seem no to be affected by the regulatory reforms in the corporate governance mechanisms. Three reasons are given: (1) the fundamental economic value of a firm is not affected by the introduction of corporate governance mechanisms; (2) the fundamental economic value of a firm is affected by the introduction of corporate governance mechanisms but due to the fact that the Greek stock market is not efficient share prices do not reflect firm’s fundamental economic value; and (3) investors may not be convinced that corporate governance mechanisms significantly affect the performance of a company.The findings of this study can facilitate legislators in improving the existing legislation concerning corporate governance and in developing a new one.

Disclosure Rules

Purpose The purpose of this study is to examine the effectiveness of financial market rules in protecting minorities. Design/methodology/approach The study compares two alternative disclosure rules on insider trading, namely, the market abuse directive (Directive 2004/72/EC), inspired from the United State (US) insider trading regulation enacted by the Sarbanes–Oxley act and the transparency directive enacted by the European (Directive 2004/109/EC) dealing with the crossing of the shareholding threshold. To investigate which one is more effective in signaling reserved information, and thus in reducing information asymmetry, the authors run an event study on the French context, where both regulations are adopted. The data were hand collected from the French stock exchange securities commissions during the two years following the implementation of the two regulations in 2004. The final sample consists of 363 insiders trading and 35 crossing shareholding thresholds for 10 top French firms during the period 2006-2007. Findings The results show that the French market reacts significantly to insider trading, but poorly to the crossing shareholding thresholds. Abnormal returns are greater after insider purchases than after crossing up thresholds. These findings support the superiority of the insider disclosure regulation, as it has better information content and provides better protection to minorities. Research limitations/implications The study contributes to the corporate governance literature by comparing two disclosure-trading policies. The authors conclude that regulation of disclosure of insider trading along the lines of US disclosure rules is more informative to the market and thus more relevant and important than disclosure of cross-threshold trades. Practical implications The study contributes to the corporate governance literature by comparing two disclosure-trading policies. The authors conclude that regulation of disclosure of insider trading along the lines of US disclosure rules is more informative to the market and thus more relevant and important than disclosure of cross-threshold trades. This finding can be helpful for the securities lawmakers and regulators in the process of insider trading law enforcement. Originality/value Previous researchers approached the question of insider trading focusing on the identity of insiders. In the research, the authors address the question from another perspective, namely, the crossing of thresholds. Another methodological contribution of the study is the use of a market model that incorporates GARCH (generalized autoregressive conditional heteroskedastic) effect and time-varying systematic risk parameter (β), which is recommended to tackle the classical event study problem of detecting the exact timing of the event.

The Empirical Analysis

The study tested the response of stock prices around the dividend declaration dates in Pakistan stock exchange. It estimated the data of 1110 dividends announced by 91 firms of the highest ten active sectors of Pakistan Stock Exchange. To empirically investigate the relationship between stock returns and dividend announcement, the panel regression was employed by creating dummy variables for 61 days around the dividend declaration dates. Cumulative average abnormal returns and average abnormal returns were also stimated around the events with the help of event study methodology. Outcomes of the empirical analysis revealed strong evidence of market abuse in the term of insider trading and supported the argument of the information content hypothesis and semistrong form of efficient market. Moreover, the study also found a robust impact of the probable ex-dividend date. The study recommended that it is a responsibility of stock exchange regulatory authorities, whistleblowers, registered companies, and the investors collectively to detect and punish this white-collar financial crime.
