Thesis (M.M. (Finance & Investment))--University of the Witwatersrand, Faculty of Commerce, Law and Management, Graduate School of Business Administration, 2014. / The use of a Covered Call strategy has long been favoured by investors the world over for its potential to enhance yield in a long-only equity portfolio. There already exists a wealth of research examining the risk and return features and theories of this strategy. This paper aims to contribute to this debate by conducting research that is specific to the South African equity market and considered from the perspective of a retail investor, particularly by tracking the negative friction induced by transaction costs. It also seeks to answer the question of which Covered Call strategies provide the best risk-adjusted returns by pricing various expiry range and moneyness combinations over differing market trend phases during a 13-year period of trade on the JSE.

Thesis (MScEng (Industrial Engineering))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: Applying the Industrial Engineering systems approach, this dissertation utilised the theories and propositions of previous studies to argue (model) the cause of financial herd behaviour and the subsequent momentum effect. From this, a hypothesis was postulated to test: whether momentum is a common attribute amongst top performing shares, whether technical analysis indicators can better identify the phenomenon, and whether the return from these shares would justify momentum as a viable investment strategy. A unique experiment derived from previous academic studies was adapted to explore the degree of the momentum phenomenon. This was done by ranking shares according to both technical analysis as well as pure price performance momentum criteria. Returns were translated as a rank in relation to the market as a whole, thereby minimising any effects that different market periods could have on a momentum return relationship. The degree of the relationship was evaluated by applying the alternative Spearman Rank Order Correlation Co-efficient in conjunction with a permutation test to determine the statistical significance of any trends. The viability of the phenomenon as an investment strategy was gauged by comparing annualised average returns against both the market capitalisation weighted JSE All Share Index as well as against an un-weighted representation of the market. The results revealed a seemingly unambiguous co-dependence between momentum and return with statistically significant trends being ever present. Applying the maximum taxes and trading costs revealed that the highest ranked momentum shares did indeed outperform both market benchmarks from the period of January 1990 to August 2009, suggesting the validity of the philosophy as an investment strategy. The outcome of the study in part rejected the null hypothesis, as technical indicators were unable to identify future top performing shares better, with price performance momentum measures delivering the superior returns. Future studies may include optimising the various technical indicators towards the JSE rather than using generic settings. Other interesting topics could include combining momentum with other investment strategies to investigate synergy and further pinpointing the source of the phenomenon. Over the past number of years, tighter controls and monitoring of investments has resulted in the documentation of the individual number of shareholders who are buying and selling shares. Utilising this data over the next number of years, an experiment could attempt to relate the number of individual investors trading in a particular share to herd behaviour and the subsequent momentum effect. / AFRIKAANSE OPSOMMING: Die verhandeling, binne die bedryfsingenieursstelsels benadering, gebruik teorieë en voorstelle van vorige studies om die gevolge van finansiële gedrag en die gevolglike momentum effek te bespreek. Uit die analise is ‘n voorstel saamgestel om die volgende te toets:Is momentum ‘n algemene verskynsel by aandele wat goed presteer, en kan tegniese analitiese indikatore die verskynsel beter verklaar, en dui die opbrengs van die aandele daarop dat momentum ‘n bruikbare beleggingsstrategie is. ‘n Unieke eksperiment uit vorige studies is aangepas om die aard van die momentum verskynsel te ondersoek. Dit was gedoen deur aandele volgens beide tegniese analise asook suiwer prestasie momentum kriteria te klassifiseer. Opbrengste is met die hele mark in konteks geplaas om sodoende enige impak van verskillende mark tye op die momentum opbrengs verhouding te elimineer. Die verband is opgestel deur die alternatiewe “Spearman Rank Order Correlation koëffisiënt” saam met permutasie toetse te gebruik om die statistiese belangrikheid van enige neigings uit te wys. Die geldigheid van die verskynsel as ‘n beleggingsstrategie is gemeet deur jaarlikse gemiddelde opbrengste teen beide die markkapitalisasie geweeg teen die JSE Alle Aandele Indeks sowel as ‘n ongeweegde verteenwoordiging van die mark te bepaal. Die resultate dui op ‘n interafhanklikheid tussen momentum en opbrengste met statistiese neigings altyd teenwoordig. Deur die maksimum belasting en verhandelingskoste toe te pas wys dit dat die hoogste momentum uitgewyste aandele die markriglyne uitpresteer het van Januarie 1990 tot Augustus 2009 wat die geldigheid van die benadering as ‘n beleggingsstrategie bevestig. Die studie verwerp die nul hipotese gedeeltelik in die sin dat dit nie toekomstige top presterende aandele kan uitwys nie, maar aan die ander kant gee prysprestasie momentum meting wel buitegewone opbrengs. Toekomstige studies mag die optimisering van verskeie tegniese indikatore van die JSE insluit, ‘n kombinasie van momentum met ander beleggingsstrategieë gebruik, en verder die bron van die verskynsel vas pen. Oor die afgelope aantal jare het beter beheer en die monitoring van beleggings die dokumentasie van individuele aandeelhouers moontlik gemaak. Hieride data sou kon gebruik word as ‘n toets om die korrelasie tussendie aantal aandeelhouers wat ‘n spesifieke aandeel verhandel en tropgedrag te bepaal en om dit te gebruik om die momentum effek beter te verklaar.

M.Com. (Business Management) / South African companies now realise that they have a responsibility to ensure that the natural resources as well as the people living within the communities in which they operate must be preserved and nurtured to ensure that future generations enjoy their benefits as much as the current generation does today. Companies are under ever-increasing pressure from both internal and external stakeholders to consider the environmental and social impacts of their operations and to mitigate these impacts. To this end, sustainable development (SD) has gained significant importance and the reporting of sustainability performance is the means by which companies communicate their efforts to their stakeholders. This study analyses the relationship between sustainability performance and financial performance to ascertain whether the ‘business case’ for sustainability exists in South African listed companies. There has been a substantial amount of research on the topic of SD and its implications for companies; the focus for this study however is on whether sustainability initiatives are important indicators of financial performance. Research conducted by Montabon, Sroufe and Narashiman (2007:998), assessed the relationship between corporate reporting, environmental management practices and company performance, however the unit of analysis was North American, British and Australian companies. This study will replicate the study of Montabon et al, with a focus on South African Johannesburg Stock Exchange (JSE) listed companies. In addition, comparisons will be drawn between developed world companies and companies within an emerging market. Pertinent literature on the topic has been reviewed and the results will be compared to the work of Artriach, Lee, Nelson, and Walker, J. (2010); Reed (2001) as well as Porter and van der Linde (1995). The results of the study reveal that an overall positive relationship exists between sustainability performance and financial performance thus, the research supports the notion that efforts to preserve and nurture environmental and human resources lead to improved financial performance.

In this thesis I investigate the impact of outside directors experience on company value. I do so by looking at a clear event, company delistings in the time period 2003 to 2011 in South Africa, a country with arguably imperfect institutions. Based on qualitative and quantitative research I am able to establish that director experience is indeed associated with company value. The qualitative analysis is based on semi-structured interviews with over 30 highly experienced, independent non-executive directors who have/had seats on over 150 South African listed company boards. Their responses confirm resource theory dependency and provide information on the nature of experience, its relevance during delisting and under other circumstances, as well as insight into the type of experience lacking on boards in corporate South Africa. The results of this research can be of practical use to nomination committees and has implications for future South African governance code reforms and/or guidelines.

Liquidity is a measure of the ease with which an asset can be converted into cash. In a perfectly liquid market, conversion is instantaneous and does not incur costs. Amihud and Mendelson (1986:224) proposed that illiquidity increases the expected return on an investment (liquidity premium) and simultaneously lengthens the holding period. These two effects are known respectively as the “spread-return relationship” and the “clientele effect” and have theoretical as well as practical implications. From a theoretical perspective it may help to explain the gap between the capital asset pricing model (which assumes that markets are perfectly liquid) and the associated empirical evidence; which thus far has been rather poor. From a practical perspective, liquidity will influence stakeholders’ decisions and market competitiveness (Amihud&Mendelson, 1991:61-64). The relevant stakeholders are governments, stock exchange regulators, corporations, investors and financial intermediaries. Emerging economies such as the South African economy typically have less liquid markets than the developed world. While this may be attractive for investors looking for higher returns, Amihud and Mendelson (1991:61) are of the opinion that liquid markets are more generally favoured by investors. Constantinides (1986:842-858), also proposes a model for liquidity, but found the liquidity premium to be of lesser importance than that proposed by Amihud and Mendelson (1986:223-231) but also supports the suggestion that investors will favour liquid markets. Although it is by no means a perfect proxy, a security’s bid-ask spread has been found to be an attractive and effective measure of liquidity. It has been found to correlate with beta as well as market capitalisation and several other variables commonly used in capital markets research. Because of this correlation the effect of the bid-ask spread cannot be studied in isolation when regression techniques are employed (Ramanathan, 1998:166). This is particularly problematic because empirical evidence for beta, which is arguably the most important independent variable in financial cross sectional relationships, is weak. Beta has to be estimated and so it is not clear if real markets do not support CAPM theory or if beta cannot be estimated with the required accuracy. All of the common independent variables used in empirical capital markets research are correlated to beta, and for this reason it cannot be established if these variables have a real effect or if they are simply serving as a proxy for the difference between the real and the estimated beta. Various strategies have been proposed to increase the accuracy of beta estimation and these are discussed in detail in this research. Successes with these strategies have been mixed. A second problem encountered in the empirical research base relating to the CAPM is that in the theory the cross-sectional relationship is between expected market return (which cannot be observed due to the vast number of real investments beyond those listed on exchanges) and beta, whereas empirical research makes use of actual return on a market proxy and beta. In order for the actual return to approach the expected return, empirical studies have to be conducted over extended periods. Accurate data for such periods are generally lacking and severe macro-economic changes such as wars, may also affect rational economic behaviour. It has to be kept in mind that the entire CAPM theory flows from the simple assumption that investors aim to achieve the highest return per unit of risk, and so a rejection of beta is a rejection of rational investor behaviour. Liquidity however, addresses one of the assumptions of CAPM, namely that markets are perfectly liquid; which obviously is not met in real markets and so CAPM models expanded for liquidity should be a reasonably fundamental starting point for all empirical capital markets research. The current empirical evidence for the spread-return relationship is inconclusive. While some researchers have found a significant relationship, others have questioned the ability of the methodology to differentiate a true relationship from the ‘proxy for errors in the estimated beta’ problem. Deductions (as explained in section 4.3) that have been made from the research of Marshall and Young (2003:176-186) in particular, provide strong evidence that at least some of the relationship is due to the ‘errors in estimated beta’ problem. Little empirical work has been done on the clientele effect. Atkins and Dyl (1997:318-321) found a significant relationship between holding period and bid-ask spread, although their approach was somewhat unorthodox in the sense that portfolio formation was not done and the effect of beta was not tested. This study tests empirically both the spread-return relationship and the clientele effect on the Johannesburg Stock Exchange over the period stretching from January 2002 to June 2007. The methodology of Fama and Macbeth (1973:614-617) as well as the aggregated beta of Dimson (1979:203-204) were mainly used, with some modifications as suggested by other researchers. With regard to the spread-return relationship, the findings of this study do not support theoretical expectations. This may be due to the short time period that was used as well as the difficulty in estimating beta. To the contrary, very significant evidence for the clientele effect was found, with little to no influence from market capitalisation and beta, which is as expected. Further investigation into the spread-return relationship is required. If a liquidity premium is not present, foreign investors will favour liquid developed markets above the JSE. This implies that efforts of exchange regulators and the government to decrease illiquidity will lead to foreign portfolio investment inflow into the South African economy. / Dissertation (MBA)--University of Pretoria, 2008. / Graduate School of Management / unrestricted

The corporate governance set-up in South Africa has undergone fundamental changes during the past decade, with the country today being responsive to most corporate governance issues. South Africa should be complimented for its King Code on Corporate Governance, the Companies Act and Johannesburg Securities Exchange Listing Requirements which have significantly strengthened the country’s corporate governance framework. These legal instruments have been influential in limiting directors’ powers and regulating the way directors are remunerated as a way of achieving good corporate governance. The research discusses the South African corporate governance framework with particular focus on the legal and regulatory framework that seeks to regulate directors’ powers and remuneration. An evaluation of the extent to which the legal and regulatory framework restrains directors’ powers and curbs excessive remuneration is undertaken. Recommendations are then provided on how the existing framework can be improved to adequately and effectively regulate directors’ powers and remuneration so as to achieve good corporate governance. / Mercantile Law / LL.M.

Thesis (MBA (Business Management))--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: Corporate governance in South Africa was institutionalised by the publication of the King Report on Corporate Governance in 1994. The King Reports were set up to ensure transparency and accountability within companies. The second King Report on corporate governance for South Africa was released in 2002 and compliance with certain aspects of the report made compulsory as a listing requirement for companies trading on the Johannesburg Stock Exchange in 2003. These requirements adopt an approach of comply or explain, and companies have to report on whether they comply with the recommendations of the second King report, or have to explain the reason for such non-compliance. In 2004 the Johannesburg Stock Exchange launched the SRI Index with the aim to facilitate investment in such companies that have adopted the triple bottom line approach to reporting. The Global Reporting Initiative (GRI) develops and disseminates globally applicable sustainability reporting guidelines which provide a framework for reporting on an organisation’s economic, environmental, and social performance. The first draft guidelines of the GRI were released in 1999 and updated in 2002. The third generation (3G) of the reporting guidelines were released in October 2006. The focus of this research project was to conduct a survey on all companies that are listed on the Johannesburg Stock Exchange All Share Index as well as the companies listed on the JSE SRI Index, with the aim of giving some insight into the development of corporate governance and sustainability reporting applied by South African companies. The findings of the 2006 study were compared to the findings of a similar study on compliance on integrated sustainability reporting done in 2004, and trends were identified, analysed and discussed. Specific focus was placed on the reporting on issues of climate change, biodiversity and compliance with applicable sector charters. The 2006 survey established that overall reporting on sustainability and governance issues has improved, that companies are publishing additional detail on the implementation of BEE and transformation policies and that corporate governance and ethical compliance have been entrenched in the companies’ corporate culture. Environmental management is the matter that was least reported on. / AFRIKAANSE OPSOMMING: Korporatiewe bestuur in Suid Afrika was geinstitusionaliseer deur die publikasie van die King Verslag oor Korporatiewe Bestuur in 1994. Die King Verslag was ontwikkel om deursigtigheid en aanspreeklikheid in maatskappye te verseker. Die tweede Verslag oor Korporatiewe Bestuur in Suid Afrika was vrygestel in 2002 met sekere aspekte van die verslag wat verpligtend is as ’n maatskappy wil noteer op die Johannesburgse Effektebeurs. Die verslag vereis van maatskappye om ’n standpunt in te neem van voldoening of verduideliking. Die maatskappy moet ’n verslag inlewer om redes te verskaf hoekom hulle voldoen aan die regulasies, of verduidelik hoekom hulle nie aan die regulasies van die tweede King Verslag voldoen het nie. In 2004 het die Johannesburgse Effektebeurs die SRI Indeks bekend gestel met die doel van fasilitasie vir beleggings in maatskappye wat die ’triple bottom line’ standpunt aanwend. Die ’Global Reporting Initiative’ ontwikkel en versprei globale riglyne vir ’triple bottom line’ verslagdoening – dit verskaf 'n raamwerk vir verslagdoening van ’n organisasie se ekonomiese, omgewings en sosiale optrede. Die eerste stel riglyne is vrygestel in 1999 en aangepas in 2002. Die derde generasie van die riglyne is vrygestel in Oktober 2006. Die fokus van die navorsing was alle maatskappye wat op die JSE All Share Indeks geregistreer is asook die maatskappye wat deel vorm van die JSE SRI Indeks, met die doel om insig te gee in die ontwikkeling van korporatiewe maatreëls en verslagdoening wat toegepas word deur Suid Afrikaanse maatskappye. Die resultate van die 2006 studie is vergelyk met resultate van ’n soortgelyke studie in 2004. Spesifieke fokus was geplaas op verslagdoening oor sake met betrekking tot klimaatsverandering, biodiversiteit en voldoening met toepaslike sektor verslae. Die 2006 ondersoek het bevind dat algehele verslagdoening verbeter het; dat maatskappye verdere inligting beskikbaar stel oor die implementasie van swart ekonomiese bemagtiging, transformasie beleid en korporatiewe bestuur; en dat etiese voldoening ge-integreer was in die maatskapy se korporatiewe kultuur.

Thesis (MBA (Business Management))--Stellenbosch University, 2008. / ENGLISH ABSTRACT: This research report investigated whether evidence of volatility clustering exists on the FTSE/JSE Top 40 Index. The presence of volatility clustering has practical implications relating to market decisions as well as the accurate measurement and reliable forecasting of volatility. This research report was conducted as an in-depth analysis of volatility, measured over five different return interval sizes covering the sample in non-overlapping periods. Each of the return interval sizes' volatility were analysed to reveal the distributional characteristics and if it violated the normality assumption. The volatility was also analysed to identify in which way, if any, subsequent periods are correlated. For each of the interval sizes one-step-ahead volatility forecasting was conducted using Linear Regression, Exponential Smoothing, GARCH(1,1) and EGARCH(1,1) models. The results were analysed using appropriate criteria to determine which of the forecasting models were more powerful. The forecasting models range from very simple to very complex, the rationale for this was to determine if more complex models outperform simpler models. The analysis showed that there was sufficient evidence to conclude that there was volatility clustering on the FTSE/JSE Top 40 Index. It further showed that more complex models such as the GARCH(1,1) and EGARCH(1,1) only marginally outperformed less complex models, and does not offer any real benefit over simpler models such as Linear Regression. This can be ascribed to the mean reversion effect of volatility and gives further insight into the volatility structure over the sample period. / AFRIKAANSE OPSOMMING: Die navorsingsverslag ondersoek die FTSE/JSE Top 40 Indeks om te bepaal of daar genoegsame bewyse is dat volatiliteitsbondeling teenwoordig is. Die teenwoordigheid van volatiliteitsbondeling het praktiese implikasies vir besluite in finansiele markte en akkurate en betroubare volatiliteitsvooruitskattings. Die verslag doen 'n diepgaande ontleding van volatiliteit, gemeet oor vyf verskillende opbrengs interval groottes wat die die steekproef dek in nie-oorvleuelende periodes. Elk van die opbrengs interval groottes se volatiliteitsverdelings word ontleed om te bepaal of dit verskil van die normaalverdeling. Die volatiliteit van die intervalle word ook ondersoek om te bepaal tot watter mate, indien enige, opeenvolgende waarnemings gekorreleer is. Vir elk van die interval groottes word 'n een-stap-vooruit vooruitskatting gedoen van volatiliteit. Dit word gedoen deur middel van Lineêre Regressie, Eksponensiële Gladstryking, GARCH(1,1) en die EGARCH(1,1) modelle. Die resultate word ontleed deur middel van erkende kriteria om te bepaal watter model die beste vooruitskattings lewer. Die modelle strek van baie eenvoudig tot baie kompleks, die rasionaal is om te bepaal of meer komplekse modelle beter resultate lewer as eenvoudiger modelle. Die ontleding toon dat daar genoegsame bewyse is om tot die gevolgtrekking te kom dat daar volatiliteitsbondeling is op die FTSE/JSE Top 40 Indeks. Dit toon verder dat meer komplekse vooruitskattingsmodelle soos die GARCH(1,1) en die EGARCH(1,1) slegs marginaal beter presteer het as die eenvoudiger vooruitskattingsmodelle en nie enige werklike voordeel soos Lineêre Regressie bied nie. Dit kan toegeskryf word aan die neiging van volatiliteit am terug te keer tot die gemiddelde, wat verdere insig lewer oor volatiliteit gedurende die steekproef.

Thesis (MBA)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: This study examines the extent to which the industrial companies listed in the Johannesburg Securities Exchange complied with the disclosure provisions of the Accounting Standards AC101 when publishing their financial statements for the years 2000 to 2002. This study further evaluates the accuracy of the reporting of the salaries and wages as presented in their Value Added Statements. Published financial statements for the years 2000 to 2002 of more than 160 companies were analysed and evaluated. The study also identifies companies that did not disclose staff costs and directors' emoluments in their financial statements as well as those companies that reported the labour portion of their wealth distribution accurately in their Value Added Statements. / AFRIKAANSE OPSOMMING: Die studie dek die mate waarin genoteerde industriële maatskappye op die Johannesburgse Effektebeurs voldoen het aan die openbaarmakingsvereistes van die Rekeningkundige Standaarde RE101 ten opsigte van hul finansiële state soos van 2000 tot 2002 gepubliseer. Die studie let verder ook op die akkuraatheid van die verslaggewing van salarisse en lone in die Toegevoegdewaardestate. Gepubliseerde finansiële state vir die jare 2000 tot 2002 van meer as 160 maatskappye is ontleed en geëvalueer. Die studie identifiseer ook daardie maatskappye wat nie salariskoste en direkteursvergoeding in hul finansiële state geopenbaar het nie, sowel as diegene wat hul salarisse korrek in die Toegevoegdewaardestate openbaar het.
