These three paragraphs from Buffett’s 1991 shareholder letter really say it all. He makes it sound so easy… to that he’d probably say “investing is simple, not easy”.
“We continually search for large businesses with understandable, enduring and mouth-watering economics that are run by able and shareholder-oriented managements. This focus doesn’t guarantee results: We both have to buy at a sensible price and get business performance from our companies that validates our assessment. But this investment approach – searching for the superstars – offers us our only chance for real success. Charlie and I are simply not smart enough, considering the large sums we work with, to get great results by adroitly buying and selling portions of far-from-great businesses. Nor do we think many others can achieve long-term investment success by flitting from flower to flower. Indeed, we believe that according the name “investors” to institutions that trade actively is like calling someone who repeatedly engages in one-night stands a romantic.
If my universe of business possibilities was limited, say, to private companies in Omaha, I would, first, try to assess the long-term economic characteristics of each business; second, assess the quality of the people in charge of running it; and, third, try to buy into a few of the best operations at a sensible price. I certainly would not wish to own an equal part of every business in town. Why, then, should Berkshire take a different tack when dealing with the larger universe of public companies? And since finding great businesses and outstanding managers is so difficult, why should we discard proven products? (I was tempted to say “the real thing.”) Our motto is: “If at first you do succeed, quit trying.”
John Maynard Keynes, whose brilliance as a practicing investor matched his brilliance in thought, wrote a letter to a business associate, F. C. Scott, on August 15, 1934 that says it all: “As time goes on, I get more and more convinced that the right method in investment is to put fairly large sums into enterprises which one thinks one knows something about and in the management of which one thoroughly believes. It is a mistake to think that one limits one’s risk by spreading too much between enterprises about which one knows little and has no reason for special confidence. . . . One’s knowledge and experience are definitely limited and there are seldom more than two or three enterprises at any given time in which I personally feel myself entitled to put full confidence.”
