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.
