The purpose of this study is to investigate the daily return behavior of underlying common stocks in the period surrounding the option expiration date. A second purpose is to determine the variables that may be causing the differential capital market effect across firms. The hypothesis of a negative return effect in the expiration week followed by a positive effect in the subsequent week is tested first. It is shown that this pattern should be expected due to the enhanced opportunity for and profitability of position unwinding, arbitrage and manipulation activity as the expiration date approached. The study period covers 32 expiration periods from 1978 through 1981 and involves a sample of 138 underlying stocks. The study employs the market model for generating abnormal returns on a daily basis. The results support the hypothesis and in particular show that the most significant negative return behavior occurs on Thursday and Friday of the expiration week. The second phase of the study correlates, via a cross-sectional multiple regression model, the suggested expiration induced events of position unwinding, arbitrage and manipulation activities with the return behavior of the underlying stocks. It is hypothesized that those common stocks which exhibit the greatest negative returns in the expiration week are those stocks and related call options that are most heavily involved in position unwinding, arbitrage and manipulation activities. Trading volume in both the underlying stock and the options is suggested as a surrogate for these three activities. Therefore, volume is negatively related to underlying stock returns. Two additional explanatory variables of the expiration week returns are included in the regression model. A negative relationship is hypothesized if options are dually listed and a positive relationship if puts are traded. The results of the tests generally support these hypothesized functional relationships. The study concludes that, although significant abnormal returns and explanatory variables are found, the magnitudes are probably not large enough to profitably exploit after paying transaction and search costs. As puts trading appears to offset the market inefficiencies caused by call option trading, the concern of regulators that options trading unduly affects stock prices seems unwarranted.

Thesis (MBA)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: The objective of this study was to determine whether a number of hedging strategies, based on option and future contracts, can be implemented to hedge a share portfolio in a successful and cost-effective way during periods of market uncertainty. The study consists of two main sections, a review of the literature and an empirical survey. The review of the literature deals with the specifications of option and future contracts that trade on SAFEXand the use of option contracts to develop different hedging strategies. In the empirical survey the different hedging strategies were applied on a share portfolio of Rim over periods of three, six, nine and twelve months. The study yielded the following conclusions: o Call and put options can be combined in various ways to create different hedging strategies such as bear spread, straddle, strip, strangle and zero cost col/ar strateg ies. o By managing the option positions of the zero cost col/arstrategy actively, the portfolio can be hedged fully and cost effectively over any period. o The portfolio can be hedged fully and cost effectively over any period through the active management of future positions. The outcome of any hedging strategy ultimately depends on the assumptions and decisions made by the portfolio manager. / AFRIKAANSE OPSOMMING: Die doel van die studie was om te bepaal of 'n aantal verskansingstrategieë, wat op opsie- en termynkontrakte gebaseer is, suksesvol en kostedoeltreffend toegepas kan word om 'n aandeleportefeulje teen verwagte markdalings te beskerm. Die studie is in twee hoofafdelings verdeel, naamlik 'n teoretiese en empiriese ondersoek. Die teoretiese ondersoek handel oor die spesifikasies van opsie- en termynkontrakte wat op SAFEX verhandel en die gebruik van koop- en verkoopopsies om verskillende opsiestrategieë daar te stel. In die empiriese ondersoek is die verskillende verskansingstrategieë op 'n aandeleportefeulje van R1m oor 'n aantal tydperke van drie, ses, nege en twaalf maande getoets. Die volgende gevolgtrekkings kan uit die studie gemaak word: o Koop- en verkoopopsies kan in verskeie kombinasies gebruik word om verskillende verskansingstrategieë daar te stel. Voorbeelde van sulke strategieë is die bear spread-, straddle-, strip-, strangle- en zero cost collarstrategieë. o Deur die aktiewe bestuur van opsieposisies by die zero cost collar-strategie kan 'n portefeulje te alle tye ten volle verskans word. Die strategie is ook kostedoeltreffend . o Deur die aktiewe bestuur van termynkontrakte kan 'n aandeleportefeulje ook te alle tye ten volle en kostedoeltreffend verskans word. Die uiteindelike resultaat by die gebruik van termynkontrakte om 'n portefeulje te verskans, is soos by opsiekontrakte egter afhanklik van die aannames en besluite wat deur die portefeuljebestuurder geneem word.

In this study, value of demand information and the importance of option contracts are investigated for a supply chain consisting of a buyer and two suppliers in a single period setting. One supplier is cheap but prone to disruptions whereas the other one is perfectly reliable but expensive. At the beginning of the period, buyer orders from the unreliable supplier and reserves from the reliable supplier through a contract that gives buyer an option to use reserved units after getting disruption information of first supplier. We introduce three models which differ in terms of the level of information available when the ordering decisions are made. In the full information model, the options are exercised after getting disruption and demand information / in the partial information model, the options are exercised after getting disruption information before demand information. In the no information model, there is no options contract and units are ordered from the reliable supplier when buyer has no information about demand and disruption. Through the analysis of these models, we explore the value of advance demand and disruption information in the presence of an options contract.

This dissertation contains two topics in operations research. The first topic is to design a distribution network to facilitate the repeated movement of shipments from many origins to many destinations. A method is developed to estimate transportation costs as a function of the number of terminals and moreover to determine the best number of terminals. The second topic is to study dynamics of a buyer's behavior when the buyer can buy goods through both option contracts and a spot market and the buyer attempts to learn the probability distribution of the spot price. The buyer estimates the spot price distribution as though it is exogenous. However, the spot price distribution is not exogenous but is endogenous because it is affected by the buyer's decision regarding option purchases.
