Illustration: Brazilian equities slide after election upset, finance minister says selloff about positioning

Brazil's main stock index fell further on Wednesday amid fiscal fears after the surprise election defeat of Flávio Bolsonaro, who then fled to the United States, with the finance minister attributing the selloff to investors unwinding pre-runoff bets rather than a reaction to fundamentals.

Some analysts described the reaction as "overdone," suggesting it could make Brazilian equities more attractive to investors.

The election upset also highlighted shortcomings of prediction markets, which a Bloomberg columnist argued "helped fuel a political narrative that briefly created around $130 billion in stock market wealth, which subsequently vanished." The columnist warned that if it happens again around US elections, "the havoc would reach a whole new level."
