OGX Shares Tumble

摘要

Shares of Brazilian oil company OGX dropped as much as 17% on Monday following an independent report that raised doubts about its crude reserves, a blow to a company whose string of offshore discoveries has made it a magnet for investors. The tumble in shares of the Rio de Janeiro-based company, controlled by Brazil’s richest man Eike Batista, led to a $6.7 billion loss in market value.
