The Billionaire Blues - Rich Guys Not So Rich Anymore

The stock market plunge has taken a bite out of everyone's investments, but take a look at what it has cost these guys.

Take bazillionaire Warren Buffett, whose equity holdings in his company, Berkshire Hathaway, have dropped 22 percent costing him $13.6 billion. (Okay, he's still got a lot in the piggy bank.)

He's lost the most, but that's probably not a big consolation to Oracle founder Larry Ellison whose shares have dropped 24 percent losing him $6.2 billion. Or Microsoft's Steve Ballmer, who is out $5.1 billion. Or Jeff Bezos of Amazon.com whose wallet got $3.6 billion lighter.

Unlike us, of course, these guys still have billions in the bank; in case you were worried.
