Tao of Charlie Munger: A Compilation of Quotes from Berkshire Hathaway's Vice Chairman on Life, Business, and the Pursuit of Wealth With Commentary by David Clark

The old Benjamin Graham method of buying undervalued stocks required an investor to set a valuation on a company and then, when the company reaches that valuation, sell it. This approach fails because it requires us to sell not only mediocre companies as they approach their valuation but also great businesses that have a durable competitive advantage, thus killing all opportunity to profit from the expansion of the underlying value of a business that occurs over time. Charlie and Warren’s theory is that a company with a durable competitive advantage has business economics that will expand the underlying value of the business over time, and the more time passes, the more the company’s value will expand. Thus, once the purchase is made, it is wisest to sit on the investment as long as possible, because the longer we own the company, the more it grows in value, and the more it grows in value, the richer we become.
