Warren Buffett on Intelligent Investing
All the passages below are taken from the book, “The Essays of Warren Buffett, Lessons for Corporate America, Third Edition.” It was selected by Lawrence A Cunningham. and published in 2013.
Inactivity strikes us as intelligent behavior. Neither we nor most business managers would dream of feverishly trading highly profitable subsidiaries because a small move in the Federal Reserve's discount rate was predicted or because some Wall Street pundit had reversed his views on the market. Why, then, should we behave differently with our minority positions in wonderful businesses? The art of investing in public companies successfully is little different from the art of successfully acquiring subsidiaries. In each case you simply want to acquire, at a sensible price, a business with excellent economics and able, honest management. Thereafter, you need only monitor whether these qualities are being preserved.
When carried out capably, an investment strategy of that type will often result in its practitioner owning a few securities that will come to represent a very large portion of his portfolio. This investor would get a similar result if he followed a policy of purchasing an interest in, say, 20% of the future earnings of a number of outstanding college basketball stars. A handful of these would go on to achieve NBA stardom, and the investor's take from them would soon dominate his royalty stream. To suggest that this investor should sell off portions of his most successful investments simply because they have come to dominate his portfolio is akin to suggesting that the Bulls trade Michael Jordan because he has become so important to the team.
In studying the investments we have made in both subsidiary companies and common stocks, you will see that we favor businesses and industries unlikely to experience major change. The reason for that is simple: Making either type of purchase, we are searching for operations that we believe are virtually certain to possess enormous competitive strength ten or twenty years from now. A fast-changing industry environment may offer the chance for huge wins, but it precludes the certainty we seek.
I should emphasize that, as citizens, Charlie and I welcome change: Fresh ideas, new products, innovative processes and the like cause our country's standard of living to rise, and that's clearly good. As investors, however, our reaction to a fermenting industry is much like our attitude toward space exploration: We applaud the endeavor but prefer to skip the ride.
Obviously all businesses change to some extent. Today, See's is different in many ways from what it was in 1972 when we bought it: It offers a different assortment of candy, employs different machinery and sells through different distribution channels. But the reasons why people today buy boxed chocolates, and why they buy them from us rather than from someone else, are virtually unchanged from what they were in the 1920s when the See family was building the business. Moreover, these motivations are not likely to change over the next 20 years, or even 50.
We look for similar predictability in marketable securities. Take Coca-Cola: The zeal and imagination with which Coke products are sold has burgeoned under Roberto Goizueta, who has done an absolutely incredible job in creating value for his shareholders. Aided by Don Keough and Doug Ivester, Roberto has rethought and improved every aspect of the company. But the fundamentals of the business---the qualities that underlie Coke's competitive dominance and stunning economics---have remained constant through the years.
I was recently studying the 1896 report of Coke (and you think that you are behind in your reading!). At that time Coke, though it was already the leading soft drink, had been around for only a decade. But its blueprint for the next 100 years was already drawn. Reporting sales of $148,000 that year, Asa Candler, the company's president, said: "We have not lagged in our efforts to go into all the world teaching that Coca-Cola is the article, par excellence, for the health and good feeling of all people." Though "health" may have been a reach, I love the fact that Coke still relies on Candler's basic theme today---a century later. Candler went on to say, just as Roberto could now, "No article of like character has ever so firmly entrenched itself in public favor." Sales of syrup that year, incidentally, were 116,492 gallons versus about 3.2 billion in 1996.
I can't resist one more Candler quote: "Beginning this year about March 1st ... we employed ten traveling salesmen by means of which, with systematic correspondence from the office, we covered almost the territory of the Union." That's my kind of sales force.
Companies such as Coca-Cola and Gillette might well be labeled "The Inevitables." Forecasters may differ a bit in their predictions of exactly how much soft drink or shaving-equipment business these companies will be doing in ten or twenty years. Nor is our talk of inevitability meant to play down the vital work that these companies must continue to carry out, in such areas as manufacturing, distribution, packaging and product innovation. In the end, however, no sensible observer---not even these companies' most vigorous competitors, assuming they are assessing the matter honestly---questions that Coke and Gillette will dominate their fields worldwide for an investment lifetime. Indeed, their dominance will probably strengthen. Both companies have significantly expanded their already huge shares of market during the past ten years, and all signs point to their repeating that performance in the next decade.
Obviously many companies in high-tech businesses or embryonic industries will grow much faster in percentage terms than will The Inevitables. But I would rather be certain of a good result than hopeful of a great one.
Of course, Charlie and I can identify only a few Inevitables, even after a lifetime of looking for them. Leadership alone provides no certainties: Witness the shocks some years back at General Motors, IBM and Sears, all of which had enjoyed long periods of seeming invincibility. Though some industries or lines of business exhibit characteristics that endow leaders with virtually insurmountable advantages, and that tend to establish Survival of the Fattest as almost a natural law, most do not. Thus, for every Inevitable, there are dozens of Impostors, companies now riding high but vulnerable to competitive attacks. Considering what it takes to be an Inevitable, Charlie and I recognize that we will never be able to come up with a Nifty Fifty or even a Twinkling Twenty. To the Inevitables in our portfolio, therefore, we add a few "Highly Probables."
You can, of course, pay too much for even the best of businesses. The overpayment risk surfaces periodically and, in our opinion, may now be quite high for the purchasers of virtually all stocks, The Inevitables included. Investors making purchases in an overheated market need to recognize that it may often take an extended period for the value of even an outstanding company to catch up with the price they paid.
A far more serious problem occurs when the management of a great company gets sidetracked and neglects its wonderful base business while purchasing other businesses that are so-so or worse. When that happens, the suffering of investors is often prolonged. Unfortunately, that is precisely what transpired years ago at both Coke and Gillette. (Would you believe that a few decades back they were growing shrimp at Coke and exploring for oil at Gillette?) Loss of focus is what most worries Charlie and me when we contemplate investing in businesses that in general look outstanding. All too often, we've seen value stagnate in the presence of hubris or of boredom that caused the attention of managers to wander. That's not going to happen again at Coke and Gillette, however---not given their current and prospective managements.

Let me add a few thoughts about your own investments. Most investors, both institutional and individual, will find that the best way to own common stocks is through an index fund that charges minimal fees. Those following this path are sure to beat the net investment professionals.
Should you choose, however, to construct your own portfolio, there are a few thoughts worth remembering. Intelligent investing is not complex, though that is far from saying that it is easy. What an investor needs is the ability to correctly evaluate selected businesses. Note that word "selected": You don't have to be an expert on every company, or even many. You only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital.
To invest successfully, you need not understand beta, efficient markets, modern portfolio theory, option pricing, or emerging markets. You may, in fact, be better off knowing nothing of these. That, of course, is not the prevailing view at most business schools, whose finance curriculum tends to be dominated by such subjects. In our view, though, investment students need only two well-taught courses---How to Value a Business, and How to Think About Market Prices.
Your goal as an investor should simply be to purchase, at a rational price, a part interest in an easily-understandable business whose earnings are virtually certain to be materially higher five, ten and twenty years from now. Over time, you will find only a few companies that meet these standards---so when you see one that qualifies, you should buy a meaningful amount of stock. You must also resist the temptation to stray from your guidelines: If you aren't willing to own a stock for ten years, don't even think about owning it for ten minutes. Put together a portfolio of companies whose aggregate earnings march upward over the years, and so also will the portfolio's market value.
Though it's seldom recognized, this is the exact approach that has produced gains for Berkshire shareholders: Our look-through earnings have grown at a good clip over the years, and our stock price has risen correspondingly. Had those gains in earnings not materialized, there would have been little increase in Berkshire's value. 
Over the past 35 years, American business has delivered terrific results. It should therefore have been easy for investors to earn juicy returns: All they had to do was piggyback Corporate America in a diversified, low-expense way. An index fund that they never touched would have done the job. Instead many investors have had experiences ranging from mediocre to disastrous.
There have been three primary causes: first, high costs, usually because investors traded excessively or spent far too much on investment management; second, portfolio decisions based on tips and fads rather than on thoughtful, quantified evaluation of businesses; and third, a start-and-stop approach to the market marked by untimely entries (after an advance has been long underway) and exits (after periods of stagnation or decline). Investors should remember that excitement and expenses are their enemies. And if they insist on trying to time their participation in equities, they should try to be fearful when others are greedy and greedy only when others are fearful. 
[S]everal of the companies in which we have large investments had disappointing business results last year. Nevertheless, we believe these companies have important competitive advantages that will endure over time. This attribute, which makes for good long-term investment results, is one Charlie and I occasionally believe we can identify. More often, however, we can't---not at least with a high degree of conviction. This explains, by the way, why we don't own stocks of tech companies, even though we share the general view that our society will be transformed by their products and services. Our problem---which we can't solve by studying up---is that we have no insights into which participants in the tech field possess a truly durable competitive advantage.
Our lack of tech insights, we should add, does not distress us. After all, there are a great many business areas in which Charlie and I have no special capital-allocation expertise. For instance, we bring nothing to the table when it comes to evaluating patents, manufacturing processes or geological prospects. So we simply don't get into judgments in those fields.
If we have a strength, it is in recognizing when we are operating well within our circle of competence and when we are approaching the perimeter. Predicting the long-term economics of companies that operate in fast-changing industries is simply far beyond our perimeter. If others claim predictive skill in those industries---and seem to have their claims validated by the behavior of the stock market---we neither envy nor emulate them. Instead, we just stick with what we understand. If we stray, we will have done so inadvertently, not because we got restless and substituted hope for rationality. Fortunately, it's almost certain there will be opportunities from time to time for Berkshire to do well within the circle we've staked out.
Right now, the prices of the fine businesses we already own are just not that attractive. In other words, we feel much better about the businesses than their stocks. That's why we haven't added to our present holdings. Nevertheless, we haven't yet scaled back our portfolio in a major way: If the choice is between a questionable business at a comfortable price or a comfortable business at a questionable price, we much prefer the latter. What really gets our attention, however, is a comfortable business at a comfortable.
Our reservations about the prices of securities we own apply also to the general level of equity prices. We have never attempted to forecast what the stock market is going to do in the next month or the next year, and we are not trying to do that now. But [as of late 1999] equity investors currently seem wildly optimistic in their expectations about future returns.
We see the growth in corporate profits as being largely tied to the business done in the country (GDP), and we see GDP growing at a real rate of about 3%. In addition, we have hypothesized 2% inflation. Charlie and I have no particular conviction about the accuracy of 2%. However, it's the market's view: Treasury Inflation-Protected Securities (TIPS) yield about two percentage points less than the standard treasury bond, and if you believe inflation rates are going to be higher than that, you can profit by simply buying TIPS and shorting Governments.
If profits do indeed grow along with GDP, at about a 5% rate, the valuation placed on American business is unlikely to climb by much more than that. Add in something for dividends, and you emerge with returns from equities that are dramatically less than most investors have either experienced in the past or expect in the future. If investor expectations become more realistic---and they almost certainly will---the market adjustment is apt to be severe, particularly in sectors in which speculation has been concentrated.
Berkshire will someday have opportunities to deploy major amounts of cash in equity markets---we are confident of that. But, as the song goes, "Who knows where or when?" Meanwhile, if any one starts explaining to you what is going on in the truly-manic portions of this "enchanted" market, you might remember still another line of song: "Fools give you reasons, wise men never try." 
[At times when prices are high for both businesses and stocks], we try to exert a Ted Williams kind of discipline. In his book The Science of Hitting, Ted explains that he carved the strike zone into 77 cells, each the size of a baseball. Swinging only at balls in his "best" cell, he knew, would allow him to bat .400; reaching for balls in his "worst" spot, the low outside corner of the strike zone, would reduce him to .230. In other words, waiting for the fat pitch would mean a trip to the Hall of Fame; swinging indiscriminately would mean a ticket to the minors.
If they are in the strike zone at all, the business "pitches" we now see are just catching the lower outside corner. If we swing, we will be locked into low returns. But if we let all of today's balls go by, there can be no assurance that the next ones we see will be more to our liking. Perhaps the attractive prices of the past were the aberrations, not the full prices of today. Unlike Ted, we can't be called out if we resist three pitches that are barely in the strike zone; nevertheless, just standing there, day after day, with my bat on my shoulder is not my idea of fun.
