Berkshire Hathaway continued to increase its stake in U.S. homebuilder Lennar this week, bringing its total holdings to 11.2% with a value of $2.1 billion. However, the pace of its purchases appears to have slowed. According to a filing with the U.S. Securities and Exchange Commission (SEC) late Wednesday, Berkshire purchased $53.6 million worth of Lennar Class A shares and $329,000 worth of Class B shares between Monday and Wednesday.
