Warren Buffett, the maestro of Berkshire Hathaway, is not your ordinary investor. He dances to the rhythm of his own tune. He's the maverick who shrugged off a credit downgrade of U.S. debt and boldly declared that Berkshire Hathaway bought $10 billion in U.S. Treasuries. This move embodies his contrarian spirit, his readiness to pounce on opportunities when others tread cautiously.
