"The message seems to be: enjoy the gains while they last," Oppenheimer said.
With the World Cup due to start on June 12 with the first match between Brazil and Croatia, Goldman isn't the only financial institution with a view on the tournament. Unicredit also tips Brazil to beat Argentina in the final, with Germany and Uruguay as the losing semifinalists.

Goldman's predictions were based on a mathematical model that analyzed 14,000 competitive international matches since 1960. Unicredit projected a team's success taking into account variables such as home advantage, the number of years being a FIFA member and the points received at the last World Cup.
Comparing its model with the sporting odds on teams, Unicredit says there's little money to be made on favourites Brazil and Argentina. It recommends going "aggressively long" on Uruguay and Ghana as both are "significantly underpriced."
Goldman also published the results of a client survey showing a dream team selection for the World Cup. Argentina's Lionel Messi, Portugal's Cristiano Ronaldo and Brazil's Neymar would play as forwards, Goldman said. Messi beat Ronaldo as the most popular player by a narrow margin in the survey.
