Why American Express Is Still a Top Buffett Stock After All These Years

American Express remains one of Berkshire Hathaway’s top three holdings, alongside Apple and Coca-Cola, as Berkshire kept AXP while exiting Visa and Mastercard in Q1. The article argues Amex’s closed-loop network, premium branding, and high-spend customer base support a strong moat, with 2024 average transaction value at $150 versus about $94 for Mastercard and $91 for Visa. It also cites a 2.3% net charge-off rate and ongoing dividends/buybacks as evidence of resilient fundamentals, though the piece is primarily a stock-pitch rather than new market-moving news.

Analysis

The market is still underestimating how much of AXP’s durability is really a mix shift story, not just a payments story. If premium spend continues to outgrow mass-market card spend, Amex’s revenue pool benefits twice: higher merchant economics and a more stable loan book, which matters because the business can fund buybacks through a downturn without needing to re-rate for credit stress. That creates a “quality premium” setup where fundamentals can improve even if the stock is already treated as a defensive financial.

The more interesting second-order effect is on Visa and Mastercard. Berkshire’s exit is not a proof point against their networks so much as a signal that, at current pricing, the incremental upside may be more muted than the market assumes if the best spenders increasingly concentrate on a closed-loop ecosystem. If premium consumers keep consolidating discretionary travel and entertainment into higher-fee products, the capturable economics tilt toward issuers with scale plus underwriting, not pure toll collectors.

The main risk is that the premium customer cohort is less cyclical, but not non-cyclical. A sharp slowdown in business travel, premium retail, or a labor-market air pocket would pressure transaction growth first and credit quality later, meaning the stock can de-rate on volume before losses show up. That makes the next 1-2 quarters more about spend growth and share gains than charge-offs; if spend decelerates, the current optimism becomes fragile fast.

Consensus may also be overstating Berkshire’s endorsement as a fresh catalyst. The bigger read-through is that buybacks and dividends can keep compounding per-share economics, but the multiple only deserves to expand if management can prove that high-spend customer acquisition remains efficient after years of premium-brand saturation. On balance, the setup looks constructive, but not for the reason most headlines imply: the real edge is capital efficiency plus underwriting resilience, not brand alone.

Key Decisions for Investors

• Long AXP vs. short MA in a 3-6 month pair trade: AXP has better embedded credit economics and a clearer path to per-share compounding if premium spend holds; stop if MA reaccelerates transaction growth by >2 pts for two consecutive quarters.
• Buy AXP on 5-8% pullbacks with a 12-month horizon: use weakness to build a core long, targeting continued buyback-supported EPS growth and lower drawdown risk than other financials.
• Sell/underweight V and MA into strength over the next 1-2 quarters: if the market is paying peak multiple for pure networks, the risk/reward is poorer than issuer-owned economics; hedge with a basket short rather than single-name if possible.
• If AXP implied vol spikes on any consumer slowdown scare, consider selling cash-secured puts 10-15% below spot for 3-6 month expiry: monetizes the market’s tendency to overreact to transient spend data while keeping downside defined.
• Monitor premium travel and restaurant spending as the key catalyst set; if those indicators roll over for two months, cut AXP exposure proactively because the stock will likely discount slower growth before losses appear.
