American Express Trades 21% Below Peak With P/E at 18.6 — Buffett's Core Holding Now a Value Proposition

The Quick Take

• American Express (AXP) is trading 21% below its all-time high at a P/E of 18.6 — below the market average
• Buffett's Berkshire Hathaway holds AXP as one of its largest equity positions, providing institutional confidence signal
• The 18.6 P/E creates a potentially expanding multiple if AmEx sustains premium spend and fee revenue resilience

American Express stock has drifted 21% below its all-time high, creating a valuation entry point for investors who believe in the quality of its closed-loop payment network. At a P/E of 18.6, AXP trades at a notable discount to both its own historical premium and to fintech peers that have re-rated on AI integration narratives. Analysts have flagged the discount as potentially compelling given AmEx's demonstrated ability to maintain elevated spending volume even during consumer slowdown periods.

Warren Buffett's Berkshire Hathaway has maintained American Express as one of its highest-conviction equity positions for decades, a signal that institutional confidence in the business model remains intact. AmEx's differentiation from Visa and Mastercard lies in its direct relationship with card members and merchants — the closed-loop network generates proprietary data and fee income that pure payment rails cannot replicate. Card member spending has held above pre-pandemic levels across the affluent demographic that AmEx primarily serves.

The bull case for AXP rests on P/E multiple expansion from 18.6 toward 22-25x as growth visibility improves. If AmEx sustains 10-12% EPS growth, the stock could double in five years from compound growth and multiple expansion. The bear case centres on credit quality deterioration if the affluent consumer segment faces unexpected income shock or on competitive pressure from JPMorgan Sapphire and Citi premium travel offerings. Delinquency rates and spend volume in the current rate environment are the key variables to track.
