It is widely believed among South African agricultural market participants that the United States' corn price, as represented by the Chicago Board of Trade-listed corn contract, is causal to the price of white and yellow maize traded on the South African Futures Exchange. Although a strong correlation exists between these markets, the corn contract is far from causal to the South African maize price, as indicated by Auret and Schmitt (2008). Similarly, South African market participants believe that volatility generated in the United States corn market spills over to the South African market. Given the perceived volatility spill-over from the corn market to the maize market, market participants might inadvertently include a higher volatility component in an option price in the South African maize market than is necessary. This study sought to quantify the amount of volatility spill-over to the South African white and yellow maize market from the United States corn contract. This task was accomplished by applying an Exponential Generalised Auto Regressive Conditional Heteroscedasticity model, within an aggregate shock framework, to the data. The findings indicated that the volatility spill-over from the United States corn market to the South African maize market is not statistically significant. This result suggests that volatility in the South African market is locally driven; hence, it should not be necessary for a South African listed option contract to carry an international volatility component in its price. It was also found that the returns data of the South African maize market is asymmetrically skewed, indicating that bad news will have a greater effect on the price of maize compared with good news. / Thesis (MCom (Risk Management))--North-West University, Potchefstroom Campus, 2013.

In the African continent the mobile phones are already contributing theirshare in the development of the continent. Specially in Ethiopia, in onedirection, the users of mobile phones are increasing each year and mostimportantly the small scale farmers who contribute 85% of the country’spopulation are using these devices to trade their surplus products in anefficient manner and better deal thus earn good profit. In anotherdirection, Ethiopia has set up its own Commodity Exchange in 2008 sothat farmers and traders could buy and sell commodities in an efficientand transparent manner. Taking into consideration both of thesedevelopments carried out to encourage smooth trade and modernmarking strategies, this project has a target to come up with mobileapplications for the Android mobile platform and iPhone users in the firstphase of implementation. Accordingly, the app developed will help to getreal time Ethiopia commodity Exchange (ECX) market prices, commodityrelated headlines, weather forecasts and other relevant news. It willcontribute to standardize the way ECX is performing to link up differentparties specially farmers who make up majority of the country’spopulation and support the economy of the country in a great deal withthe traders. Although the mobile app developed does not have an aim tobring in significant change into the existing system at the currentpenetration of Smartphone in the country, it helps to disseminateinformation in standardized manner as in big commodity exchanges andbesides, we believe in the future it will be the convenient and widely usedmeans to reach the traders with necessary information.

Corn production is scattered geographically over various continents, but most of it is grown in the United States. As such, the world price of corn futures contracts is largely dominated by North American corn prices as traded on the Chicago Board of Trade. In recent years, this market has been characterised by an increase in price volatility and magnitude of price movement as a result of decreasing stock levels. The development and implementation of an effective and successful derivative price risk management strategy based on the Chicago Board of Trade corn futures contract will therefore be of inestimable value to market stakeholders worldwide. The research focused on the efficient market hypothesis and the possibility of contesting this phenomenon through an application of a derivative price risk management methodology. The methodology is based on a combination of an analysis of market trends and technical oscillators with the objective of generating returns superior to that of a market benchmark. The study found that market participants are currently unable to exploit price movement in a manner which results in returns that contest the notion of efficient markets. The methodology proposed, however, does allow the user to consistently achieve returns superior to that of a predetermined market benchmark. The benchmark price for the purposes of this study was the average price offered by the market over the contract lifetime, and such, the efficient market hypothesis was successfully contested. / Business Management / D.
