This article presents a case study touching on the subject of the relationships occurring between events, which are not of economic nature, and the rates of return of the listed companies. The subject of the research concerns the relationship between sport and the stock exchange. The case study used sporting results and bookmakers’ expectations (betting odds) for the matches played by Borussia Dortmund, whose shares are quoted on the Frankfurt Stock Exchange. It was assumed that this relationship stems from the emotions of football fans who may be stock market investors. This assumption is justifi ed by the highest TV ratings of BVB matches both "live" and in front of the TV screens as well as the high attractiveness of securities issued by the BVB GmbH & Co. KGaA. The data used in the study came from the web service transfermarkt.de and Xetra market for the period of 2011–2014. Research methods employed for this study were the econometric models, including models of (G)ARCH type, and statistical tests of signifi cance.
