Warren Buffett built one of the most iconic investment portfolios in history at Berkshire Hathaway over more than six decades. As of the Q4 2025 13F filing (reported February 17, 2026), Berkshire’s U.S. equity portfolio stood at approximately $274 billion, with the top 10 holdings accounting for 88.26% of the total.
Greg Abel officially became CEO on January 1, 2026, with Buffett remaining as Chairman. Abel’s first shareholder letter (dated February 28, 2026) underscores continuity: “Berkshire’s foundation is second to none… We move forward with great intent and purpose.” The portfolio Greg Abel inherits is concentrated, disciplined, and focused on durable businesses with economic moats.
This in-depth analysis examines how the portfolio was constructed, the ten largest positions, Abel’s role in the next chapter, market factors that could influence it, and why Wall Street continues to watch Berkshire’s every move.
Inside the Investment Portfolio Built Over Decades
How Berkshire Hathaway Assembled Its Most Valuable Holdings
Berkshire Hathaway began as a struggling textile mill when Buffett took control in 1965. He pivoted the company into a vehicle for intelligent capital allocation, using insurance float as low-cost leverage to buy high-quality businesses and stocks.
Key milestones include the 1988 purchase of Coca-Cola (still a cornerstone today), the 1990s buildup in financials like American Express and Wells Fargo (later trimmed), and the landmark 2016 Apple investment that became the largest holding. Buffett, Todd Combs, and Ted Weschler added positions methodically, always at prices offering a margin of safety.
The philosophy remains unchanged under Abel: buy wonderful companies at fair prices and hold them forever when possible. The letter explicitly reaffirms this approach, noting concentrated equity investments in “U.S. companies we understand well.”
Long-Term Strategy Behind the Company’s Largest Positions
Berkshire’s strategy emphasizes economic moats, predictable cash flows, strong management, and reasonable valuations. Insurance operations generate float (now $176 billion), which funds investments without the pressure of external capital.
Buffett and now Abel prioritize businesses that compound intrinsic value over decades. The portfolio’s low turnover (2.38% in Q4 2025) reflects this patience.
Japanese trading houses (Mitsubishi, ITOCHU, Mitsui, Marubeni, Sumitomo) add geographic diversification, valued at $35.4 billion with low-cost yen borrowing.
Why Certain Companies Became Cornerstones of the Portfolio
Cornerstone holdings share timeless traits: consumer staples (Coca-Cola), financial services with network effects (American Express), technology leaders (Apple), and energy majors (Chevron). These companies generate high returns on capital and return cash to shareholders via dividends and buybacks—perfect for Berkshire’s tax-efficient, long-term ownership model.
Buffett has repeatedly called certain positions “indefinite” holdings. Abel’s letter echoes this by highlighting Apple, American Express, Coca-Cola, and Moody’s as examples of durable stakes yielding $1.67 billion in dividends in 2025 alone.
A Closer Look at the Ten Largest Berkshire Hathaway Investments
Technology, Financial, and Consumer Giants in the Portfolio
As of December 31, 2025, the top holdings reflect a balanced mix across sectors:
- Apple Inc. (AAPL) — 22.6% (~$62 billion)
- American Express (AXP) — 20.46% (~$56.1 billion)
- Bank of America (BAC) — 10.38% (~$28.5 billion)
- Coca-Cola (KO) — 10.2% (~$28 billion)
- Chevron (CVX) — 7.24% (~$19.8 billion) 6–10. Moody’s (MCO), Occidental Petroleum (OXY), Chubb (CB), Kraft Heinz (KHC), and smaller positions (e.g., Alphabet GOOGL) round out the top 10 to reach 88.26% concentration.
Berkshire trimmed Apple (–4.3%, –10.3 million shares) and Bank of America (–8.9%) in Q4 while adding modestly to Chevron and Chubb—classic capital reallocation at work.
How These Holdings Have Performed in Recent Years
Apple delivered extraordinary returns since 2016 but faced valuation pressure in 2025, prompting trims. American Express and Coca-Cola provided steady dividend growth and resilience during market volatility. Chevron benefited from energy prices and strategic additions. Bank of America’s position, built via warrants, has been partially harvested as the bank trades at attractive valuations.
Overall, Berkshire’s concentrated approach has compounded capital at superior rates for decades, though scale now limits outsized gains—Abel openly acknowledges this mathematical reality in his letter.
Why Investors Closely Track Berkshire’s Quarterly Filings
The 13F filings offer a 45-day-delayed but transparent window into the thinking of one of history’s greatest capital allocators. Moves often influence other institutional investors and can move individual stock prices. With Abel at the helm, every filing will be scrutinized for signs of continuity versus subtle evolution.
Greg Abel’s Role in the Next Chapter of Berkshire Hathaway
Leadership Transition Taking Shape Inside the Company
Greg Abel, who joined Berkshire via the 1999 acquisition of MidAmerican Energy (now Berkshire Hathaway Energy), rose through operational excellence. He has served as Vice Chairman overseeing non-insurance operations since 2018 and was named successor in 2021. Buffett stepped down as CEO effective December 31, 2025; Abel assumed the role January 1, 2026.
Buffett remains active as Chairman, working five days a week and available for major decisions.
Management Style and Investment Philosophy Under Discussion
Abel’s letter is a masterclass in humility and continuity. He quotes Charlie Munger: “Greg will keep the culture.” He sent a company-wide memo reaffirming unchanged values and attached it to the shareholder letter.
Investment oversight remains disciplined. Ted Weschler manages roughly 6% of the portfolio; Abel and the team focus on high-conviction, understandable businesses.
Decisions That Could Influence the Composition of the Portfolio
Abel has already signaled patience. No wholesale changes are expected. The eight “indefinite” holdings Buffett highlighted previously—Apple, American Express, Coca-Cola, and others—remain core. Cash exceeds $370 billion, providing dry powder for acquisitions or buybacks when stocks trade below intrinsic value.
Share repurchases and opportunistic add-ons (e.g., recent Chevron and Chubb increases) will likely continue. Major sales would only occur if fundamentals deteriorate permanently.
Market Factors That Could Affect Berkshire’s Investment Positions
Shifting Economic Conditions and Industry Trends
Interest rates, inflation, and geopolitical risks remain key variables. Higher rates pressure growth stocks like Apple while benefiting financials. Energy prices directly impact Chevron and Occidental. Consumer spending trends affect Coca-Cola and Kraft Heinz.
Abel’s letter highlights insurance as the “heart” of Berkshire—float growth and underwriting discipline will remain paramount regardless of cycles.
Stock Valuations and Capital Allocation Considerations
Berkshire trimmed Apple partly because its price-to-earnings multiple stretched beyond historical averages. Abel and the team continue evaluating opportunities on a per-share intrinsic value basis. With $370+ billion in cash and Treasuries, Berkshire can act decisively when fear creates bargains.
Investor Attention Focused on Possible Portfolio Adjustments
Analysts and copycat funds watch for any deviation from Buffett’s playbook. Early signals under Abel—modest trims, continued buybacks, and emphasis on operational excellence—suggest evolution rather than revolution.
How Berkshire Hathaway’s Portfolio Continues to Influence Wall Street
Institutional Investors Following Buffett’s Investment Approach
Thousands of investors and funds benchmark against Berkshire’s 13F. Value-oriented managers study the moat analysis behind Apple, the long-term ownership of Coca-Cola, and the financial-sector weighting.
Portfolio Moves Often Setting the Tone for Market Conversations
When Berkshire trims Apple or adds to energy, media headlines follow. The concentrated nature (88%+ in top 10) amplifies visibility. Abel’s first letter already sparked discussions about the “post-Buffett era” while reassuring markets of continuity.
Why Berkshire Hathaway Remains One of the Most Watched Investors
No other public company combines insurance float, operating businesses, and a massive equity portfolio under one disciplined philosophy. Berkshire’s fortress balance sheet, zero dividend policy (while value-creating opportunities exist), and long-term horizon set it apart.
As Greg Abel wrote: “Our opportunity is improvement in per-share value over the long term… with a constant focus on managing downside risk for our owners.”
The portfolio he inherits is not just a collection of stocks—it is the embodiment of six decades of rational capital allocation. Under Abel’s stewardship, Berkshire Hathaway’s influence on Wall Street and the broader investment community will endure for generations.
