PETROBRAS is trading at BRL 52.50, down 10.53% on October 26, as investors unwind positions built around a Flávio Bolsonaro victory after Lula da Silva won Brazil’s runoff election. - Reuters reported investors expected bets on a change of government to unwind; coverage also linked the selloff to expectations of fiscal tightening under Bolsonaro. - The move reflects Brazil-wide political and fiscal repricing, not a clearly identified Petrobras-specific announcement; U.S. market gains do not explain the decline.
