Either Australia or New Zealand could be on course for a stock market rally next week depending on who wins tomorrow's Rugby World Cup final.
The financial information provider Standard & Poor's Capital IQ says research shows the last three winners of the cup have all had material increases in their respective markets index in the week following the final.
London Business School finance professor Alex Edmans said his research showed that if a national team was eliminated from an international tournament it made investors fed up and pessimistic.
He said a defeat for a national rugby team triggered a fall of 0.15 percent the following day.
However, it was not an exact science, he said. Britain's main stock index rose 3 percent after England lost to Australia earlier this month.
