The stock market doesn't always follow conventional wisdom. Last Thursday, Nintendo reported its sales figures for the last nine months of 2007, revealing that it had doubled its revenues and profits over the same period the year before. While there was an initial spike in the publisher's share price after the news, that gain has since been lost and then some, with the stock dropping nearly 10 percent of its value during Monday's trading. Nintendo shares closed the day at ¥46,800 ($438), down from its previous close of ¥51,800 ($485). The company's stock is down 36 percent from its 52-week high of ¥73,200 ($685), which it hit in October.
