American Express

American Express appears in EP80 与查理·芒格的跨时空对话：当眼睛失明时，我们看见什么？ through the 1963 salad-oil scandal and the market panic that followed. The episode uses the case to show how Charlie Munger and Warren Buffett separated a severe one-time loss from the company’s core asset: a payment and travel-check trust network still accepted by merchants and customers.

Source Position

• The episode says the scandal, compensation burden, lawsuits, and stock-price drop made investors treat American Express as deeply damaged.
• Buffett and Munger are portrayed as checking real-world behavior in restaurants, hotels, travel agencies, and merchant settings rather than relying only on Wall Street reports.
• The case becomes a lesson in crisis investing: if trust, usage, and network acceptance remain intact, market fear may overstate permanent impairment.

Connections

• Charlie Munger and Warren Buffett — investors whose field observation anchors the episode’s case.
• Berkshire Hathaway — broader investment context connected to Buffett and Munger.
• Consumer Brand Moat — American Express adds a financial-services version based on trust and network behavior.
