Just weeks ago, on August 14, Class A shares of American conglomerate Berkshire Hathaway (BRK-A) surpassed $200,000. Yes, you read that right, $200,000: making Berkshire Hathaway the single most expensive stock traded on U.S. markets. The current price of these Class A shares alone is impressive; however, when you consider that in 1967 the company traded at $33 per share, this milestone is downright insane.
