Some Groupon Investors Head to the Exits

Early investors losing faith in the new Internet boom.

Some of the early backers of Groupon Inc., including Silicon Valley veteran Marc Andreessen, are heading for the exits, joining investors who have lost faith in companies that had been expected to drive a new Internet boom.

At least four Groupon investors who held stock in the daily-deals company before it went public have sold or significantly pared back their holdings in recent months. Since its initial public offering in November, Groupon has shed more than three-quarters of its stock-market value, or about $10 billion.
