58% of Warren Buffett's $287 Billion Portfolio at Berkshire Hathaway Is Invested in Just 4 Unstoppable Stocks

Berkshire Hathaway's recent 13F filing revealed Warren Buffett's continued portfolio concentration, with roughly 58% of the $287 billion portfolio invested in just four stocks: Apple, American Express, Coca-Cola, and Bank of America. While Apple remains the largest holding, Berkshire significantly reduced its stake during the quarter, while maintaining large positions in American Express and Coca-Cola, which provide substantial yields on cost of 38.6% and 62.8% respectively, and slightly reducing its Bank of America holdings.

Analysis

Berkshire Hathaway's recent Form 13F filing, disclosed on May 15, underscores Warren Buffett's long-standing strategy of portfolio concentration, with approximately 58% of the $287 billion in invested assets allocated to just four companies. This filing comes amid significant news, including Buffett's plan to step down as CEO by year-end, with Greg Abel set to succeed him, and the company's Q1 operating results unveiled at the May 3 annual meeting. Apple (AAPL) remains the largest holding at $63.4 billion (22.1% of invested assets), though the position was substantially reduced to 300,000,000 shares as of March 31, 2025, down from 915,560,382 shares at the end of September 2023; Buffett's affinity for Apple stems from strong brand loyalty and its growing services segment. American Express (AXP) is the second-largest holding at $45.4 billion (15.8%), a position held since 1991, valued for its ability to capitalize on economic expansions and attract affluent customers, delivering a 38.6% yield on cost to Berkshire. Coca-Cola (KO), a holding since 1988, accounts for $28.8 billion (10%), praised for its recession-resistant nature, global reach, brand power, and an impressive 62.8% yield on cost based on Berkshire's original investment, with dividends recently increased for the 63rd consecutive year. Bank of America (BAC) is the fourth-largest position at $28.2 billion (9.8%); Berkshire sold 48,660,056 shares of BAC during the first quarter, and the article notes that over 401 million shares have been sold since July 17, 2024, from a larger initial stake, though Buffett appreciates its cyclical nature and interest rate sensitivity. The overall sentiment from the provided signals is moderately positive (0.3 sentiment score) with a moderate market impact score (0.4), reflecting both the continued strength of core holdings and notable reductions in others.

Key Decisions for Investors

• Investors should closely monitor Berkshire Hathaway's portfolio adjustments and capital allocation strategies under Greg Abel's upcoming leadership, given Warren Buffett's planned departure by year-end.
• The significant reduction in Apple's stake, despite it remaining the largest holding, warrants careful consideration of Berkshire's evolving view on the tech giant's valuation or future growth prospects, especially noting the reported share count as of March 31, 2025.
• The continued large holdings and exceptional yields on cost from American Express (38.6%) and Coca-Cola (62.8%) highlight Berkshire's conviction in these long-term compounders, suggesting they remain core to its value generation strategy.
• The trimming of the Bank of America position, with 48.6 million shares sold in Q1 and further significant sales noted since July 17, 2024, may signal a revised outlook on the banking sector or a strategic rebalancing by Berkshire; investors should assess this in light of broader economic and interest rate trends.
• Consider the implications of Berkshire's highly concentrated portfolio, where nearly 58% of assets are in four stocks, which, while a hallmark of Buffett's strategy, presents concentration risk that individual investors should be aware of.
