Groupon Shares Hit New Low in Latest Plunge Another day, another sell-off at Groupon, it appears. Shares in the company touched new lows on Wednesday, diving 6.5 percent. Groupon's stock closed down 54 cents, at $7.77, after trading as low as $7.72. That is well below its initial public offering price of $20 a share. Wednesday's closing price values Groupon at a little over $5 billion, less than a third of the $16.5 billion market capitalization it had at the end of its first day of trading in November, when the stock closed at $26.11. The company has had a tough time in the public markets since going public. Shares in Groupon have tumbled 70 percent since the daily deals pioneer's initial public offering. It isn't quite clear what lay behind the latest sell-off, since Groupon hasn't been a fixture in the news of late. Its chairman, Eric Lefkofsky, wrote in a blog post last week that he was reducing his day-to-day responsibilities at the company to focus on his own investment firm. But investors have long been wary of the company, skeptical that its business model will prove profitable in the long run and that its current management team is capable of leading a major public corporation. A number of issues, including disclosed weaknesses in its internal financial controls and a restatement of its earnings, haven't helped. Investors may have to wait until August to see if there's any more bad news to come out.
