Shorting Soccer Club Stocks Before Important Matches

Summary

The document describes a short-selling strategy in publicly traded soccer clubs. It proposes selling a club’s stock at the close of the business day before an important match, holding the position for one day, and equally weighting positions when multiple clubs play. The proposed explanation is that fans and other investors are too optimistic about their teams before matches, while bookmaker odds may better reflect the range of likely outcomes. When a team draws or loses, that optimism can reverse and the stock may earn a negative abnormal return.

The cited study examines European soccer club returns around important matches and uses betting-exchange contracts as a proxy for expected outcomes. Its abstract attributes part of the post-match return pattern to biased investor expectations. The document gives no performance figures, sample dates, transaction-cost estimates, or detailed risk analysis for this trading rule. It also notes that a betting-market hedge is only a theoretical extension, so the suggested short strategy should not be treated as a fully assessed arbitrage.
