Berkshire Hathaway Letters to Shareholders: 1965-2024

by Warren Buffett

Following Ben’s teachings, Charlie and I let our marketable equities tell us by their operating results—not by their daily, or even yearly, price quotations—whether our investments are successful. The market may ignore business success for a while, but eventually will confirm it. As Ben said: “In the short run, the market is a voting machine but in the long run it is a weighing machine.” The speed at which a business’s success is recognized, furthermore, is not that important as long as the company’s intrinsic value is increasing at a satisfactory rate. In fact, delayed recognition can be an advantage: It may give us the chance to buy more of a good thing at a bargain price. Sometimes, of course, the market may judge a business to be more valuable than the underlying facts would indicate it is. In such a case, we will sell our holdings. Sometimes, also, we will sell a security that is fairly valued or even undervalued because we require funds for a still more undervalued investment or one we believe we understand better. We need to emphasize, however, that we do not sell holdings just because they have appreciated or because we have held them for a long time. (Of Wall Street maxims the most foolish may be “You can’t go broke taking a profit.”) We are quite content to hold any security indefinitely, so long as the prospective return on equity capital of the underlying business is satisfactory, management is competent and honest, and the market does not overvalue the business.
