Abnormal Returns of Soccer Teams: Reassessing the Informational Value of Betting Odds
Published online on September 25, 2013
Abstract
We analyze the links between soccer match results, betting odds, and stock returns of all listed European soccer teams. Using an event-study approach, we measure positive (negative) abnormal returns following wins (ties and losses). Additionally, we analyze the role, which we find to be nonsignificant, of betting odds in shaping market reactions to unexpected results. We propose an alternative econometric approach, using seemingly unrelated regressions models, to take into account the problem of overlapping events. Abnormal returns following unexpected results are then found to be statistically significant and to magnify the positive (negative) effects of wins (losses).
