Seminar paper from the year 2014 in the subject Business economics - Investment and Finance, grade: 1,0, University of Cologne (Institut fur Finanzierungslehre), course: Seminar Investment Myths, language: English, abstract: The main objective of this paper is the evaluation of the investment value of expert strategies in stock investment with regard to higher profits than the overall market.
