1 Top Warren Buffett Stock Trading 21% Below Its All-Time High That Can Double a $1,000 Investment in 5 Years

American Express trades at 18.6x earnings, 23% below its multiple at the start of 2026 and 21% below its December 2025 record high. Management targets mid-teens long-term EPS growth; assuming its P/E expands to 20x over five years, the article estimates the shares could double by late 2031. Berkshire Hathaway remains a major holder, owning 22.5% of American Express shares valued at $46.3B.

Analysis

AXP’s rerating case is less about a mechanical return to a prior multiple and more about whether its affluent-cardmember franchise can sustain spend, loan growth, and credit normalization simultaneously. At an 18-19x earnings multiple, the stock is already priced as a premium payments/consumer-finance hybrid; incremental upside requires evidence that billed-business growth remains above the industry while provisions stay contained. A weaker consumer backdrop would expose the embedded operating leverage: rewards and marketing are comparatively sticky investments, while discount revenue and net interest income can decelerate quickly.

The more actionable relative-value implication is AXP versus V and MA. AXP has greater exposure to credit, travel-and-entertainment spending, funding costs, and its own rewards economics; V/MA retain transaction-volume exposure with materially less balance-sheet and reserve risk. Over the next 1-3 months, monthly consumer-spending indicators, receivables growth, delinquency trends, and management’s marketing/rewards guidance matter more than generalized Berkshire association. BRK.A’s large stake is strategically supportive but does not create a near-term valuation floor; portfolio concentration could instead amplify attention if Berkshire ever signals trimming.

Consensus may be underestimating the cost of maintaining premium customer acquisition as competitors intensify rewards offerings. Conversely, if AXP demonstrates that younger affluent cohorts are net-accretive after rewards and acquisition costs, the market could assign a more durable growth multiple over 6-18 months. The key falsifier is a combination of billed-business deceleration, reserve build above management’s normalized outlook, or guidance that EPS growth falls below low-teens without offsetting capital return.

Key Decisions for Investors

• No outright AXP chase on this low-information, promotional article; establish a watch level around the next earnings release and act only if billed-business growth, credit metrics, and EPS guidance independently support durable mid-teens growth.
• For a defensive payments expression over the next 3-6 months, favor long V or MA versus short AXP in equal-dollar size if consumer credit delinquencies or AXP reserve guidance deteriorate. The trade captures AXP’s incremental credit/funding/rewards-cost exposure; cover if AXP’s spend growth accelerates while provisions remain stable.
• For investors already long AXP, retain exposure only with a defined earnings trigger: reduce on a guide-down to sub-low-teens EPS growth or a material increase in rewards/marketing intensity without corresponding cardmember acquisition and spend growth.
• Monitor BRK.A disclosures and public comments for any change in AXP ownership. A meaningful reduction would be a near-term technical overhang for AXP even if fundamentals are unchanged, creating a potential entry opportunity only after the selling pressure is quantified.
