We will then detail how the current macro environment will likely affect the main business areas of Berkshire before determining our fair value estimate and 12-month price target. At the outset, we should state that we are focusing on Berkshire Hathaway B shares, which are more accessible. Warren Buffet does not generally believe in share splits with the result that the original A shares of Berkshire Hathaway trade at $421,000 approximately. Yes, that is right, nearly half a million dollars to buy one share in BRK.A. Thankfully lower-priced B class shares were introduced in 1996 in response to demand from small investors for a slice of Buffet's pie.
