The occurrence of insider trading in target shares of JSE listed companies prior to takeover announcementsVan der Plas, Francois 27 March 2010 (has links)
Research into whether insider trading exists in the shares traded on the Johannesburg Stock Exchange (“JSE”). The purpose of the research is to examine the share price in target companies and to determine whether or not it increases significantly during the days immediately preceding a takeover, delisting or share buy-back announcement. Out of a total of 5,039 merger and acquisition transactions, during the six- year period from 2000 to 2005, only 30 transactions met the criteria of information availability and non-occurrence of confounding events. The Average Cumulative Abnormal Returns (CAAR) of target companies during a 21-day event window period were examined. The examination of the CAAR was based on the historical bootstrapping technique and the CAAR was plotted on the frequency distribution to test for significance. The CAAR of the sample tested to be statistically significant in the days prior to the first public announcement. Evidence of a share price build-up in the days prior to the first public announcement was found. Controlling for confounding events, this price build-up could be indicative of insider trading. This research study seems to be the first study focused on insider trading and pre-announcement price run-ups on the Johannesburg Stock Exchange. / Dissertation (MBA)--University of Pretoria, 2010. / Gordon Institute of Business Science (GIBS) / unrestricted

Insider trading as a signal used in investment decisions on the AltX : the influence of insider ownership and controlBaty, Michael 23 April 2010 (has links)
Much work has been conducted on the signalling effect that a directors’ trade has on outsiders. This is based on the premise that insiders, or directors, shareholders and managers of companies have access to information about their companies that outsiders do not (Bhana, 2007; Fidrmuc, Goergen and Renneboog, 2006; Hodgson and van Praag, 2006), raising questions about the efficiency of markets (Fidrmuc, Goergen and Renneboog, 2004). Other research concludes that the greater the shareholding percentage or percentage control held by an insider, the greater would be their access to company information, and that this would lead directly to an increase in the strength of the signal to the market. Hillier and Marshall (2002) find that the abnormal returns occur most strongly where directors have increased their shareholding. Fidrmuc, Goergen and Renneboog in various studies found that the opposite is true, particularly for purchases, citing a perceived danger of increased entrenchment as the reason for this anomaly. This study will use the AltX of the JSE and attempt to show that there is a positive return on shareholder investment following an insider purchase and a negative return on investment following an insider sale as outsiders react to these signals and the information contained in these trades. This study will also attempt to prove that the percentage control of a director who purchases their own shares has an inverse relationship to the abnormal returns. This study uses the event study methodology and analyses the abnormal returns in the event windows extending back to twenty days prior to the events and for the following twenty days after the event. Abnormal returns are modelled using the control portfolio model of Mordant and Muller (2003) which is based on the Fama and French Three-Factor model. These abnormal returns are then tested for significance using T-tests and the bootstrapping technique. Relationships between shareholding interest and returns is established using linear correlation. No statistical significance could be found on the returns compared to the market following either a purchase or sale insider trade. However, it was found that the reaction to purchases was significantly higher than the reaction to sales, and results indicate that the reaction to sales on the AltX of the JSE leads to abnormal losses in the short term. This study finds that there is no indistinguishable relationship between shareholding and returns that are different to zero. While it is clear that other bourses internationally demonstrate clear evidence of the existence of signals contained in insider trades, and other South African studies find corroborative evidence on the JSE main board, there is no evidence that insider trades on the AltX contain any signalling value in them for outsiders, particularly pertaining to purchases. Although not economically significant, sales do suggest that there is information contained in the trade, but is this reaction in the market due to the information contained in the trade, or simply due to a culture of trading on market sentiment? / Dissertation (MBA)--University of Pretoria, 2010. / Gordon Institute of Business Science (GIBS) / unrestricted

Abnormal volumes traded as an indication of insider trading in JSE listed companiesThaver, Kuben 12 May 2010 (has links)
Insider trading is one of the most unscrupulous financial crimes, as it results in people placed in positions of trust effectively stealing from those that they were supposed to protect. This research examined the volumes traded in shares listed on the JSE All Share index, to determine if it could be used as an indicator of insider trading, and whether it increases significantly in the days immediately preceding SENS announcements. The top five abnormal returns per share were generated using control portfolios. These were analysed manually to identify the most appropriate SENS announcement. From the 735 abnormal returns, 142 announcements qualified for the volume analysis, after the removal of confounding events. These announcements were classified into seven categories: BEE and governance; financial structure; investment/disinvestment; key personnel; mergers and acquisitions; trading update; and other. The average daily cumulative abnormal volume turnover (ACAVT) was examined using a 21-day event window period preannouncement. The preceding 63 days were used to calculate the benchmark. Three techniques were used to calculate ACAVTs – equations, t-tests and bootstrapping - which proved successful in determining ACAVT. The tests showed that overall the ACAVT was statistically insignificant. Two categories exhibited significant ACAVT – BEE and governance, and key personnel. / Dissertation (MBA)--University of Pretoria, 2010. / Gordon Institute of Business Science (GIBS) / unrestricted

Quantitative analysis of quota trading behaviour at the end of the quota yearSterelyukhin, Alex 05 1900 (has links)
The Canadian supply management system offers some lessons for the design of a domestic permit trading system. One of the objectives of the domestic trading system is minimizing costs and maximizing the system's efficiency for participants and system administrators. This paper suggests that a permit trading system designed with a longer permit period and without a grace period can be more efficient than a system designed with a shorter permit period and a grace period for compliance. This study is based on Canadian Supply Management System experience and examines the Canadian dairy industry, where two different schemes (monthly and annual) have been used. Under the annual scheme, a strong compliance mechanism stimulates participants to exchange quotas during the dairy year (permit period) and does not require burdensome, non-compliance procedures after the permit period ends. The monthly scheme is characterized by a short permit period and a grace period for compliance. This study examines how these two schemes affect participants' behavior on the quota exchange. The empirical results show evidence of the influence of different schemes on farmers' behaviours regarding the quota exchange. As a conclusion, the paper recommends the use of a permit trading mechanism with a longer permit period and without a grace period for the design of a carbon trading system. The results support Barichello (2002), who developed the Canadian domestic permit trading scheme on the basis of receiving an offset from agricultural soil carbon sinks. / Land and Food Systems, Faculty of / Graduate
