Seminar paper from the year 2011 in the subject Business economics - Investment and Finance, grade: 1,0, University of Hull, course: Current Issues Financial Management, language: English, abstract: The study examines and critical reviews the literature for the different implications based onthe three levels of the Efficient Market Hypothesis for investors and company managers. Ifthe weak form of the EMH holds, the technical analyse is useless, but ninety percent oftraders in London are using it. If the semi-strong-form holds the fundamental analysis, studyof published accounts, search for undervalued companies are useless and investors should befocus on diversification and avoiding of transaction costs. Furthermore the semi-strong formwould imply for managers, that accounting disclosure to deceived shareholders is useless, thecompany market value is the best indicator for the company value and management decisions,the company does not need specialists for the timing of issues and there are no opportunitiesfor a cheap acquisition of another company. At least if the strong-form of the EMH holds, itwould imply that even with insider information it would not be possible to get above averagereturns. The literature shows, that the studies of EMH have made an important contribution toour understanding of the security market. It also shows that in some cases scientific results donot strong influence the behaviour of manager and investors in the "real world".
