However, victories do not show a corresponding rise.
Øyvind Norli, an associate professor at BI Norwegian School of Management, Diego Garcia from the Tuck School of Business at Dartmouth and Alex Edmans from MIT have conducted comprehensive research into the connection between results of international football games and returns on national share indexes.
Sports results affect people’s moods, including those who deal in shares. How does the stock market react to sharp changes in investors’ moods? This was the question asked by the three research workers, who conducted a thorough investigation into whether share rates are affected by the moods of buyers and sellers in a particular market.
Norli & Co studied international football results for the period 1973 to 2004, looking at qualifiers, group matches and the final rounds of the FIFA World Cup and Cup games played in Europe, Asia and South America. The data covers matches played in a total of 39 footballing countries, i.e. those which have historically made a mark for themselves in the World Cup.
The results were published in the article “Sports Sentiment and Stock Returns” in the well known professional periodical Journal of Finance.
Losing in the final round of the World Cup causes an average loss of 0.38% in the main share index of the country in question. Here the researchers took account of movement patterns in the international shares market generally and only measured the abnormal rate change after the game. “We found that there was a dramatic fall in the share market after an important football match was lost,” declares Norli.
A stock exchange fall of 0.38% may not sound very much, but compared with positive average daily returns of about 0.06%, the football-related fall in the share market is substantial both statistically and financially. Norli and his colleagues also documented similar loss effects in other important international sports, such as cricket, rugby, ice hockey and basketball.
Norli explains, “The fall in the share market can be regarded as the result of a change in how investors see the future. Losing an important international football match creates a general feeling of pessimism among the inhabitants of a country, and naturally a pessimistic investor will revise his view of what companies quoted on the stock exchange are worth.”
But even if investors are in a much better mood if the national team wins an important World Cup game, this does not result in a rate rise.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
