The results show that F_SCORE generated a69,7 % annual return between 2001-2010 at the Swedish market, which was better than the furtherdeveloped model A_SCORE. Overall, the evidence suggests that the market does not incorporatehistorical information into prices in a timely manner.Methodology: The foundation for this thesis is based on a quantitative approach and empiricalmaterial is gathered from Thomson Reuters Datastream for the Swedish market..
