BRASILIA, Feb 25 (Reuters) - Brazil’s President Jair Bolsonaro said on Thursday there was an “exaggeration” in the market reaction to his announcement that he was replacing the chief executive of state-controlled oil company Petrobras . He said in a social media talk to supporters: “A lot of people made money. The smart guys made money.” Petrobras shares plunged and the company lost 100 billion reais ($18 billion) in market value in two days after he announced the move on Friday in a social media post.
