Priceline: 11 Years

Led by Jeffery Boyd, who has been in the chief executive role at Priceline.com since 2002, the online travel agency recently forecast second-quarter profit that trailed analysts' estimates. With its international sales threatened by Europe's economic slump, shares fell on the news. Still, the stock is up 34.9 percent this year, a positive note to Boyd's first decade running the company.
