Josh Brown: Berkshire Hathaway could be on the verge of undergoing the mother of all re-ratings

Josh Brown, Ritholtz Wealth Management CEO, joins 'Closing Bell' to talk about Berkshire Hathaway. The biggest Snowflake takeaway is Berkshire Hathaway, says Brown. I think it's on the verge of undergoing the mother of all re-ratings. They bought Amazon last year, and now they're buying pre-IPO venture-backed companies. Everyone expects them to keep making clumsy 20th-century investments. No one is valuing this company as thought they could seriously play in the 21st century.
