Alphabet: Abel’s first quarter after taking over triples its stake
Berkshire first bought Alphabet shares in the third quarter of 2025; under Abel’s leadership, in the first quarter of 2026 the stake nearly tripled, making Alphabet Berkshire’s fifth-largest concentrated holding. Alphabet’s AI Overview and AI Mode features are deeply integrated with Google Search, driving search activity to accelerate growth for four straight quarters.
Coca-Cola and Apple: fundamentals of long-term holdings
Coca-Cola: Between 1988 and 1994, Buffett spent $1.3 billion to buy 400 million shares and has never sold a single share; the current value of the stake is $32.7 billion. Apple: From 2016 to 2023, Buffett invested about $38 billion; in early 2024, the stake’s market value exceeded $170 billion (nearly half of the entire portfolio). He then sold about three-quarters to reduce concentration risk; Apple still remains Berkshire’s largest single holding at 20.7%. When Buffett was interviewed by CNBC, he said he is glad Apple is still Berkshire’s largest holding.
Frequently asked questions
Why did Berkshire significantly sell Apple shares, yet still keep it as the largest holding?
From 2016 to 2023, Buffett invested about $38 billion to buy Apple; in early 2024, the market value exceeded $170 billion, roughly half of the portfolio. To reduce concentration risk and cash in part of the gains, Buffett sold about three-quarters of the stake from 2024 to 2025, but Apple still maintains its position as Berkshire’s largest single holding at 20.7%.
How does Greg Abel’s investment strategy differ from Buffett’s?
Abel is described as a faithful supporter of Buffett’s long-term value investing strategy, focusing on companies with steady growth, reliable earnings, and shareholder-friendly actions. In the first quarter of 2026, Abel tripled Berkshire’s Alphabet stake, showing that he continues Buffett’s approach of adding more to companies with clearly identifiable fundamentals.
What is Berkshire’s basis for its bet on Google Search advertising prospects?
Google Search hit a record $60.4 billion in revenue in the first quarter of 2026, up 19% year over year, with accelerating growth for the fourth consecutive quarter. Alphabet’s AI Overview and AI Mode functions show that AI integration is driving overall search activity growth rather than weakening the business.
