Berkshire Hathaway's New Portfolio: 61% in 5 Stocks

A year after Warren Buffett's retirement as CEO, his successor Greg Abel has put his own stamp on Berkshire Hathaway's massive investment portfolio. The changes revealed in recent regulatory filings are dramatic. Abel sold off a third of the holdings Buffett oversaw in his final quarter, eliminating 16 positions entirely.

This sweeping overhaul has resulted in a remarkably concentrated portfolio. A staggering 61% of Berkshire's $330 billion in invested assets is now parked in just five companies. This marks a significant shift towards a more focused, high-conviction investment strategy under new leadership.

The top holding remains Apple, which constitutes nearly 22% of the portfolio despite Buffett having sold down 75% of the stake before retiring. Abel has labeled Apple a 'multidecade compounder' in his first shareholder letter, signaling its continued importance.

Following Apple are longtime Buffett favorites American Express and Coca-Cola, both designated as 'indefinite' holdings that Abel has vowed not to touch. Bank of America rounds out the financial exposure, though both Buffett and Abel have been trimming this position. The most aggressive new bet is on Alphabet, where Berkshire more than tripled its stake, making it the fifth-largest holding.

For investors, this portfolio concentration signals a clear investment philosophy from the new CEO. Abel is doubling down on businesses with what he and Buffett call 'sustainable moats'—unassailable competitive advantages. This move away from diversification towards a handful of elite companies is a bold statement of confidence.

The strategy also highlights a focus on shareholder returns. Several of these core holdings, like Apple, are renowned for massive buyback programs. Others, like Amex and Coke, provide Berkshire with jaw-dropping 'yield on cost' from dividends—as high as 65% for Coke—thanks to decades-old, low-cost positions. This income is a bedrock of Berkshire's value.

Furthermore, Abel's additions show an eye towards future growth engines. The massive increase in the Alphabet stake and the emphasis on Apple's AI integration suggest Abel is positioning the portfolio to benefit from technological shifts, while still anchoring it with timeless consumer and financial brands.

Finally, this concentration creates a clearer read-through for the market. The performance of Berkshire Hathaway's stock is now more directly tied to the fortunes of this handful of mega-cap companies. It simplifies the investment thesis but also increases the importance of each holding's execution.
