Apple set a series of market cap milestones last year, passing $200 billion in early March, leapfrogging Wal-Mart just a few days later, and passing Microsoft in late May to become the second largest U.S. company by market capitalization behind Exxon Mobil. Apple continues to trail Exxon Mobil, which also had a strong performance in the latter half of 2010 and currently sits at a market cap of about $368 billion.
