Make any mistakes at work yesterday? Not like this guy... According to today's New York Times business section: ...Admitting to what could be Japan's biggest trading error ever, the brokerage unit of Mizuho Finanacial Group Inc. said after the close of trading on Thursday that a worker had entered what was intended as an order to sell one share of J-Com, an employment services company based in Osaka, at 610,000 yen. Instead, the order went out to sell 610,000 shares - valued at $3.1 billion at J-Com's initial offering price - for one yen each...The error has so far caused a loss of some 27 billion yen ($324 million).
