11:37 MF MF Global: Color on stock action (5.20 -12.13) -Update-
MF has plunged 70% today, on no apparent news. In late Feb the stock got cut in half after the co disclosed an unauthorized trading loss related to an employee that took a wheat futures position in his personal trading account that went the wrong way... We're hearing a couple of rumors circulating about today's weakness, including the following 1) chatter about the co's exposure to repos, and 2) concerns about a lawsuit regarding co's risk management... We're still checking around, and have left a message with the company.
