Buffett's Core Portfolio: Apple, Coke, and Alphabet Dominate Berkshire Holdings

Warren Buffett's investment strategy at Berkshire Hathaway revolves around acquiring high-return businesses with structural competitive moats, then holding them for decades. Even after stepping down as CEO in 2025, his approach remains unchanged under new leader Greg Abel. Three stocks that embody this principle are Apple Inc (AAPL), Coca-Cola, and Alphabet.

Apple's closed ecosystem transforms hardware purchases into permanent software relationships, imposing steep friction on users attempting to switch to rival platforms. This user retention has created a reliable annuity from over one billion active devices, with high-margin recurring revenue streams that scale independently of annual device replacement cycles.

Coca-Cola's asset-light model insulates it from heavy capital expenditure, as the company sells concentrated syrups to independent bottling partners who absorb production and distribution costs. This franchise architecture yields exceptional operating margins while maintaining a global shelf-space advantage that new competitors cannot replicate.

Alphabet entered Berkshire's portfolio in 2025, driven by its self-reinforcing data feedback loop in digital search. The company directs billions of daily search queries into Alphabet's core ad engine through distribution deals and native ownership of Android and Chrome, enabling premium cost-per-click pricing from global advertisers.
