Mr. Market
Investing with a margin of safety
The Mr. Market framework is a mental model for investing in the stock market. It is based on the idea that the market is like a moody business partner, Mr. Market, who offers to buy or sell a portion of the business every day. The investor should take advantage of Mr. Market's irrational behavior by buying when he is depressed and selling when he is euphoric.

In the late 1980s, Coca-Cola's stock price was depressed due to concerns about the company's growth prospects. Warren Buffett took advantage of Mr. Market's irrational behavior, buying a significant stake in the company at a low price. As the market recovered, Coca-Cola's stock price soared, generating substantial returns for Berkshire Hathaway.
