Explore the Salad Oil Scandal on Stock Market Classics. Learn how Warren Buffett analyzed American Express during a massive financial fraud to find a legendary trade.

The stock market does not know or care what you paid for a stock. Your purchase price is an irrelevant historical fact; what matters is the company's intrinsic value based on its future earnings and assets.
Stock market basics for beginners, focusing on stories of famous trades to illustrate core principles and market dynamics.







The Salad Oil Scandal was a massive financial fraud discovered in 1963 involving tanks that were supposed to be filled with millions of pounds of salad oil. In reality, the tanks were filled with seawater with only a thin layer of oil on top to deceive inspectors. Because American Express had verified the oil's existence, the company faced a crisis when the fraud was revealed, causing its stock price to drop from $59 to $29.
While most investors panicked and sold their shares, Warren Buffett took a counterintuitive approach. He observed that despite the warehouse fraud in New Jersey, customers in restaurants and hotels continued to use their American Express cards. By focusing on the enduring strength of the brand and consumer behavior rather than the scandal itself, Buffett identified a unique investment opportunity while the rest of the market was in retreat.
This episode of Stock Market Classics highlights the importance of looking past market panic to evaluate the core value of a business. Warren Buffett's decision to invest in American Express during the Salad Oil Scandal demonstrates that even during a significant financial fraud, a company with a strong, functional brand can remain a viable investment. It teaches investors to distinguish between temporary reputational damage and the actual utility of a company's primary services.
