Warren Buffett's Successor, Greg Abel, Has 63% of Berkshire's $360 Billion Portfolio Concentrated in 5 Superstar Stocks

Greg Abel, who took over as Berkshire Hathaway's CEO on December 31, maintains Warren Buffett's investment philosophy of concentrating assets in best ideas. As of August 28, 63% ($226 billion) of Berkshire's $360 billion portfolio is concentrated in five stocks. Tech stocks now comprise over 30% of the portfolio, driven by significant positions in Apple and Alphabet. Abel has tripled Berkshire's Alphabet position and added $17 billion in Q2. Meanwhile, Berkshire has been reducing its Bank of America stake for eight consecutive quarters due to valuation concerns.
