According to Yahoo Finance, Berkshire Hathaway CEO Greg Abel's investment portfolio shows that over 50% of his equity investments are concentrated in three stocks: Apple (approximately 22% of his equity holdings), American Express (over 17%), and Google (nearly 13%). The article notes that although Abel has taken the helm from Buffett, these major holdings still bear the imprint of Buffett's investment philosophy. Google is highlighted as one of the new top three holdings where Buffett explicitly stated his involvement in the decision-making process.
