Why Does Buffett Own American Express?

Warren Buffett, through his company Berkshire Hathaway (BRK-B), has held a 19.4% stake in American Express (AXP) since 1991. His total purchase cost was about $8.5 billion, giving him an extremely low cost basis compared to the current stock price above $260.

Is the Stock Too Expensive Now?

After strong gains in recent years, AXP trades at a P/E ratio above 20x, higher than its historical average. Some analysts believe the market has already priced in future growth, reducing the margin of safety for new investors.

Buffett's Investment Logic

Buffett is known for long-term investments in companies with strong brands and durable competitive advantages. American Express has a loyal base of affluent customers and a profitable business model from transaction fees and interest. But the question is: does the current price fully reflect these advantages?

Bottom Line for Investors

American Express remains an excellent company, but new investors may find a better entry point on any pullback. No buy or sell recommendation is given, only a call to carefully consider the current valuation.
