The analysis undertaken, firstly aims to identify the extent to which equities, their indexes and their derivatives priced in accordance with their fair value. Secondly, presuming that the traded values of the instruments do not in all instances equate to the fair value, the research aims to develop an effective means to identify and manage profitable opportunities arising from the mispricing. General concepts relating to profitability, trade identification, risk and continuous improvement of the processes are addressed. This includes recommendations on the management of the risks through a structured reporting process. The research looks at arbitrage trading in the South African market from the perspective of an empirical review into the market's participation in equity and equity derivative arbitrage. In addition to this empirical analysis, a time series analysis into various arbitrage strategies is conducted with the view to determining their relative profitability. The first component of the empirical research focuses on the arbitrage trading strategies adopted by a sample of 80 institutions. Where the institutions trade arbitrage strategies, the research undertook to establish what methods are used to identify, trade and manage the index arbitrage, single stock futures arbitrage, risk arbitrage, statistical arbitrage and volatility arbitrage trading opportunities that present themselves within the South African Market. Information gathered did not only focus on the actual trading strategies but also determined the relative cost structures, profitability and risk management processes that are employed to support these trading initiatives. The time series analysis focused on index futures, single stock futures, risk, dual listed and statistical arbitrage methods, and reflects the results before and after transaction costs. These arbitrage strategies were applied to the ALSI Top 40 index or its associated shares and generally spanned a period of about four years. Finally the research presents an arbitrage business model that is aimed at providing a blue print for arbitrage trading which covers: new arbitrage strategy, implementation, market risk, execution, profit, traders, cost Finally, the research provides a multiple regression method for application in identifying further arbitrage trading opportunities within the South African environment. / School of Business Leadaership / DBL

The agricultural sector plays an important role in the South African economy through job creation and earning foreign exchange. The role of agricultural co-operatives increased substantially over the last few decades. The research focuses firstly on the identification of derivative instruments in the market and their applicability to mitigate financial risks co-operatives experience. Secondly, research is conducted about the extent to which co-operatives use these derivatives to hedge financial risks. The research shows that most co-operatives are exposed to financial risks through different activities. It is, however, evident that although the derivative instruments are available, not all co-operatives make use of these instruments. Recommendations for further research include the development of a risk management framework and determining the different economic factors that have an influence on the use of derivatives by South African agricultural co-operatives. / Business Management / M.Comm.

Die studie vergelyk die prestasie van 'n koop-en-hou-strategie met die van 'n tydsberekeningstrategie binne die raamwerk van die arbitrasie-prysbepalingsteorie (APT) op die nywerheidsindeks van die Johannesburgse Aandelebeurs (JA). Die periode van die studie is oor twee tydperke, naamlik Januarie 1970 tot September 1987 en Januarie 1989 tot Junie 1997. Die langtermyntendens van die nywerheidsindeks en APT-faktore is bepaal deur die beste nie-reglynige model vir elke tydreeks te vind. Reglynige meervoudige stapsgewyse regressie-ontleding is gebruik om die bewegings van die nywerheidsindeks rondom die langtermyntendens te voorspel. Die sloeringsreekse van die langtermyntendensresidutelling van die APT-faktore en die sloeringsreekse van die eerste-ordeverskiltelling van die langtermyntendensresidutelling is as moontlike voorspellers gebruik. Gegrond hierop is beslissingslyne ontwik:kel wat gebruik is vir die implementering van 'n tydsberekeningstrategie. Die resultate van die studie is die volgende: • Waar die sloeringsreekse van die langtermyntendensresidutelling van die APTfaktore as moontlike voorspellers gebruik is, is die risiko-aangepaste opbrengskoers van 'n tydsberekeningstrategie 6, 41 persent en 0, 71 persent b6 die van 'n koop-en-hou-strategie vir tydperk een en twee onderskeidelik. • Waar die sloeringsreekse van die eerste-ordeverskiltelling van die langtermyntendensresidutelling van die APT-faktore as moontlike voorspellers gebruik is, is die risiko-aangepaste opbrengskoers van 'n tydsberekeningstrategie 10,40 persent en 1,04 persent b6 die van 'n koop-enhou- strategie vir tydperk een en twee onderskeidelik. Die belangrikste gevolgtrekking van die studie is dat die APT en 'n tydsberekeningstrategie teoreties en prakties versoenbaar is op die JA. Aanbevelings vir toekomstige navorsing is die volgende: ( 1) sistematiese risikofaktore, anders as makro-ekonomiese faktore, behoort identifiseer te word wat die voorspellingswaarde van die faktore in die tweede tydperk van die studie kan verhoog; (2) elke stap van die model wat ontwikkel is, behoort op elke indeks van die JA toegepas te word om die risiko-aangepaste opbrengskoers van 'n tydsberekeningstrategie toegepas op elkeen van die indekse met die van 'n koop-en-hou-strategie te vergelyk; en (3) die invloed van transaksiekoste en dividende op die potensiele voordele van tydsberekening moet bepaal word. / The study compares the performance of a buy-and-hold strategy with that of a markettiming strategy in the framework of the arbitrage pricing theory (APT) applied to the industrial index of the Johannesburg Stock Exchange (JSE). The study period is divided into two parts, namely January 1970 to September 1987 and January 1989 to June 1997. The long-term trend of the industrial index and every APT factor is determined by finding the best nonlinear model for each time series. Linear multiple stepwise regression analysis, with the lagged time series of the long-term trend error terms of the APT factors, is used to forecast the movement of the industrial index around its long-term trend. Decision lines were developed to implement a market-timing strategy. The results of the study are as follows: • Where the lagged time series of the long-term trend error terms of the APT factors were used as possible predictors, the risk-adjusted return of a markettiming strategy was 6, 41 percent and 0, 71 percent higher than that of a buyand- hold strategy for periods one and two respectively. • Where the lagged time series of the first-order difference of the long-term trend error term of the APT factors were used as possible predictors, the riskadjusted return of the market-timing strategy was 10,40 percent and 1,04 percent higher than that of a buy-and-hold strategy for periods one and two respectively. The main conclusion of the study is that the APT and a market-timing strategy are theoretically and practically reconcilable on the JSE. The main recommendations of the study are the following: (1) systematic risk factors, other than macroeconomic factors, should be identified in order to increase the forecasting value of these factors in the second period of the study; (2) each step of the model developed in this study should be repeated on every index of the JSE; and (3) the influence of transaction costs and dividends on the potential benefits of a market-timing strategy should be determined. / Business Management / DCom (Sakebestuur)
