A recent academic study led by Alex Edmans, together with Diego García, Øyvind Norli and Richard Quest, uncovers a surprising link between the outcomes of international football matches and the performance of stock markets.
The Emotional Edge
The researchers found that a national team’s defeat, particularly in knockout stages such as the World Cup, is followed by a measurable dip in the domestic equity market on the next trading day. The impact is most pronounced among smaller‑cap stocks, where investor sentiment can swing more easily.
Beyond the numbers, the paper emphasizes that these market moves are driven not by fundamentals but by the collective psychology of investors, who react more sharply to losses than to gains.
Edmans argues that the growing influence of retail investors and the rise of sentiment‑driven trading make this phenomenon increasingly relevant in today’s markets.
He cautions against knee‑jerk reactions, suggesting that savvy investors can capitalize on overreactions by buying undervalued stocks during market dips, rather than succumbing to panic.
