Warren Buffett, the legendary investor known as the “Oracle of Omaha,” recently announced his retirement as CEO of Berkshire Hathaway effective at the end of 2025. After six decades of leadership that transformed Berkshire into one of the world’s largest companies, Buffett will step down but continue as chairman. With an estimated net worth of $159.8 million, his investment choices continue to draw worldwide attention.
Buffett’s investment philosophy centers on a long-term approach and holding winning stocks even when they grow to occupy large portions of his portfolio. This strategy is clearly visible in Berkshire’s current holdings, where just four stocks account for 57% of the company’s massive $277 billion portfolio.
Apple (AAPL) stands as Berkshire’s largest holding, with the company’s stake valued at $59.5 billion. Buffett has called the tech giant Berkshire’s “best business” since first investing in 2016. At a recent shareholder meeting, Buffett even joked that Apple CEO Tim Cook, who attended in person, has made Berkshire more money than Buffett himself ever did.
The tech company’s iOS ecosystem now connects over 2.35 billion active devices worldwide. This provides Apple with an ideal distribution channel for its subscription services and App Store fees. Though growth may have slowed for the $3 trillion company, its strong profitability and aggressive stock buyback program help maintain a solid floor for its stock price.
Banking on America’s Financial Giants
Banking stocks represent a cornerstone of Buffett’s investment strategy. He has famously stated, “If you follow sound banking methods, which means not doing some things that other people do, a bank could be a perfectly decent investment.”
American Express (AXP) ranks as Berkshire’s second-largest holding, with a stake valued between $32-43 billion (sources differ on the exact figure). Buffett’s relationship with AmEx dates back to the 1970s, with Berkshire’s formal investment beginning in 1991. The company’s focus on high-earning consumers and businesses has helped it maintain relevance across generations.
AmEx management has reported success in attracting Gen Z and millennial consumers, positioning the company well for future growth. With the United States carrying over $1.2 trillion in total credit card debt, American Express remains firmly entrenched in the financial landscape.
Bank of America (BAC) represents another major financial stake in Berkshire’s portfolio. Buffett reportedly conceived the idea to invest in America’s second-largest bank while taking a bath. In 2011, Berkshire struck a deal for preferred shares and stock warrants, eventually converting to common shares in 2017.
However, Berkshire has recently reduced its Bank of America position by 34%, selling over 300 million shares in 2025. Despite this reduction, the stake remains substantial at approximately $28-29 billion. With over $3.3 trillion in total assets, Bank of America provides broad exposure to various economic sectors, from commercial real estate to financial markets and mortgages.
Beyond Banking: The Coca-Cola Connection
Coca-Cola (KO) stands as perhaps the most iconic Buffett investment. Berkshire first purchased shares in 1988, and the beverage giant has grown to become the company’s fourth-largest holding at $28.2 billion. Buffett is frequently photographed enjoying Coke products, highlighting his personal connection to the brand.
As a Dividend King with 62 consecutive annual dividend increases, Coca-Cola delivers over $800 million in annual dividends to Berkshire alone. Despite its mature status, the company continues to find growth opportunities in a global market of 8 billion potential consumers. Coca-Cola’s ability to launch new products and acquire emerging competitors positions it for continued success.
Citigroup (C) represents a smaller but evolving position in Berkshire’s portfolio. Last year, Buffett owned 55 million Citigroup shares valued at approximately $3 billion. In 2025, Berkshire has substantially reduced this position to just under 15 million shares. This change reflects Buffett’s willingness to adjust positions when his outlook on a company shifts.
The composition of Berkshire’s portfolio provides valuable insights for individual investors. Buffett’s preference for companies with dominant market positions, strong consumer relationships, and long-term growth potential has proven successful over decades. As he transitions from CEO to chairman, his investment legacy continues to shape the financial world.
Buffett capped his investment career with a balanced portfolio that combines established giants like Coca-Cola with tech leader Apple. He maintains his heavy emphasis on financial institutions that connect directly with American consumers.
