SAO PAULO: Shares of Brazilian oil producer OGX Petroleo e Gas Participacoes SA fell as much as 35.3 percent on Thursday, the day after the company controlled by former billionaire Eike Batista filed for bankruptcy protection.
Brazil exchange operator BM&F Bovespa said late on Wednesday that it would remove OGX from its benchmark Ibovespa stock index after Thursday's session but that the shares would continue to trade.
