Berkshire Hathaway’s Class B shares closed at $512.37 on Tuesday, while Class A shares closed at $768,010, both hitting their highest levels since November 28 of last year.This followed a report by UBS (UBS) analyst Brian Meredith, who raised his price target for Berkshire’s Class B shares from $570 to $585 and for Class A shares from $854,596 to $877,848, while maintaining a “Buy” rating—a move that may have partly driven the stock’s rise.
