US Stocks Historically Tumble 2.6% During World Cup Tournaments; 2026 Edition Begins This Week

According to MarketWatch columnist Mark Hulbert citing historical data, US stocks have historically averaged a 2.6% decline during World Cup tournaments (1950–2007), with the knockout stage triggering steeper losses. In 2022, the S&P 500 dropped 5.4% during the knockout phase, while the Vanguard Global Stock ETF (VT-US) fell 4.6%.

Academic research identified an asymmetric psychological phenomenon: when a country's national team is eliminated, that nation's stock market experiences significant selling pressure the following day, yet winning nations' markets do not see corresponding rallies. Since every knockout match produces one defeated nation, this collective pessimism drags down global equities during the tournament. The 2026 World Cup begins this week, with the knockout stage commencing June 28 and the final scheduled for July 19.
