Coca-Cola and American Express: The Long-Game Logic Behind Two of Buffett's Biggest Bets

Why Buffett's Two Favorite Stocks Still Command Attention in 2026

Warren Buffett once said that if you aren't willing to own a stock for 10 years, you shouldn't own it for 10 minutes. That philosophy has guided Berkshire Hathaway's investment decisions for decades, and two of its most enduring positions — Coca-Cola (NYSE: KO) and American Express (NYSE: AXP) — continue to illustrate exactly what patient, conviction-driven investing looks like in practice.

Coca-Cola: A Business Model Built for Decades

Few companies in the world carry the kind of competitive moat that Coca-Cola has spent over a century constructing. Its beverages reach consumers in more than 200 countries daily, giving the business a level of geographic diversification that insulates it from regional economic turbulence in ways that most companies simply cannot replicate.

What makes Coca-Cola's structure particularly notable is its asset-light approach. Rather than owning the capital-intensive manufacturing and distribution infrastructure itself, the company functions primarily as a concentrate producer — selling syrups and bases to an independent network of local bottling partners. This model allows Coca-Cola to expand globally while keeping capital expenditure relatively low, preserving margins and maintaining tight control over brand strategy and pricing.

That pricing power has proven durable through multiple inflationary cycles. When input costs rise — whether it's sugar, aluminum, or packaging materials — the company has historically demonstrated an ability to pass those costs along to consumers without triggering meaningful volume declines. Everyday beverages at accessible price points tend to remain sticky even when household budgets tighten.

Berkshire Hathaway has held its Coca-Cola position since 1988, accumulating 400 million shares over time. The holding now generates hundreds of millions of dollars in annual dividend income for Berkshire, a testament to the compounding effect of reinvesting a growing dividend over decades. Coca-Cola carries a 64-year streak of consecutive dividend increases, qualifying it as a Dividend King, with a current yield hovering around 2.6%.

American Express: The Closed-Loop Advantage

American Express occupies a structurally different corner of the financial world than traditional banks or payment networks. Its closed-loop ecosystem means the company simultaneously acts as the card issuer and the payment processor — collecting fees from merchants at the point of sale while also earning interest income, annual fees, and late fees directly from cardholders.

This dual revenue stream gives Amex a data advantage that competitors operating on open networks struggle to match. The proprietary transaction data flowing through its system allows the company to target marketing with high precision, keeping customer acquisition costs competitive and retention rates strong.

Amex's deliberate focus on affluent, high-spending customers has proven to be a meaningful differentiator. This demographic tends to maintain spending levels during economic slowdowns and presents lower default risk compared to the broader credit card market — two qualities that help stabilize the business when financial conditions deteriorate.

The financial results reflect this strength. In its most recent full-year report, American Express posted a record $72 billion in revenue, a 10% increase from 2024, alongside a 15% jump in adjusted earnings per share to $15.38. Analysts also note a built-in inflation hedge embedded in the business model: because Amex collects percentage-based fees on transactions, rising nominal prices for goods and services automatically translate into higher fee revenue.

The company has continued returning capital to shareholders, most recently raising its dividend by 16%. The stock currently yields approximately 1%.

The Bigger Picture: What Long-Term Holding Actually Looks Like

Berkshire's positions in both companies offer a real-world case study in what compounding over decades can produce. The Coca-Cola stake, now more than 37 years old, generates passive income that dwarfs the original cost basis. The American Express position, similarly long-held, has grown into one of Berkshire's largest equity holdings by market value.

For investors analyzing these businesses today, the relevant question isn't about short-term price movements — it's about whether the underlying structural advantages that made these companies attractive decades ago remain intact. Data suggests both businesses continue to evolve their competitive positioning while preserving the core characteristics that Buffett has long described as essential: durable moats, pricing power, and management aligned with long-term value creation.

What to Watch Going Forward

For Coca-Cola, key metrics to monitor include volume trends across emerging markets, the company's ability to manage input cost inflation, and continued dividend growth. For American Express, investor attention will likely focus on card spending trends, credit loss rates among its cardholder base, and whether the premium consumer segment remains resilient amid shifting economic conditions.

Both companies report quarterly results that offer regular windows into the health of their respective competitive positions — providing ongoing data points for investors tracking these long-term stories.
