Berkshire Hathaway’s stock symbol is BRK.A, and its Class A shares are known for one of the highest prices on a stock exchange.
Berkshire Hathaway’s Class A shares have never undergone a conventional split, so their per-share price has risen dramatically as the business and its investments expanded. The company introduced Class B shares in 1996, giving smaller investors a lower-priced alternative with different voting rights.
The Class A ticker is BRK.A on the New York Stock Exchange, while the Class B ticker is BRK.B. The two classes represent the same company but do not have identical economic and voting rights.
The high share price is not itself the reason Berkshire is valuable: market capitalization depends on share price multiplied by the number of shares. Buffett has also argued that an unsplit share price encourages long-term ownership and discourages excessive trading.
