Berkshire's Moody's downgrades Buffett


In what surely must be the PR move of the decade, Moody's Corp. (MCO) has downgraded Berkshire Hathaway (BRK.A) from AAA to AA2.

Why is this a great PR move? Well, Berkshire owns 20 percent of Moody's. And what could be a better demonstration of Moody's independence and objectivity than its decision to downgrade the financial strength of its biggest shareholder?
