First there’s mathematics. Obviously, you’ve got to be able to handle numbers and quantities—basic arithmetic. And the great useful model, after compound interest, is the elementary math of permutations and combinations. And that was taught in my day in the sophomore year in high school. I suppose by now in great private schools, it’s probably down to the eighth grade or so.

It’s not that hard to learn. What is hard is to get so you use it routinely almost everyday of your life. The Fermat/Pascal system is dramatically consonant with the way that the world works. And it’s fundamental truth. So you simply have to have the technique.

If you don’t get this elementary, but mildly unnatural, mathematics of elementary probability into your repertoire, then you go through a long life like a onelegged man in an asskicking contest. You’re giving a huge advantage to everybody else.

Obviously, you have to know accounting. It’s the language of practical business life. It was a very useful thing to deliver to civilization. I’ve heard it came to civilization through Venice which of course was once the great commercial power in the Mediterranean. However, double-entry bookkeeping was a hell of an invention.
 And it’s not that hard to understand.

In terms of the limitations of accounting, one of my favorite stories involves a very great businessman named Carl Braun who created the CF Braun Engineering Company. It designed and built oil refineries—which is very hard to do. And Braun would get them to come in on time and not blow up and have efficiencies and so forth.
 This is a major art.

He had another rule, from psychology, which, if you’re interested in wisdom, ought to be part of your repertoire—like the elementary mathematics of permutations and combinations.

His rule for all the Braun Company’s communications was called the five W’s—you had to tell who was going to do what, where, when and why. And if you wrote a letter or directive in the Braun Company telling somebody to do something, and you didn’t tell him why, you could get fired. In fact, you would get fired if you did it twice.

You might ask why that is so important? Well, again that’s a rule of psychology. Just as you think better if you array knowledge on a bunch of models that are basically answers to the question, why, why, why, if you always tell people why, they’ll understand it better, they’ll consider it more important, and they’ll be more likely to comply. Even if they don’t understand your reason, they’ll be more likely to comply.

Which models are the most reliable? Well, obviously, the models that come from hard science and engineering are the most reliable models on this Earth. And engineering quality control—at least the guts of it that matters to you and me and people who are not professional engineers—is very much based on the elementary mathematics of Fermat and Pascal:

It costs so much and you get so much less likelihood of it breaking if you spend this much. It’s all elementary high school mathematics. And an elaboration of that is what Deming brought to Japan for all of that quality control stuff.

I don’t think it’s necessary for most people to be terribly facile in statistics. For example, I’m not sure that I can even pronounce the Poisson distribution. But I know what a Gaussian or normal distribution looks like and I know that events and huge aspects of reality end up distributed that way. So I can do a rough calculation.

And by the way, that works well enough. But you have to understand that bellshaped curve at least roughly as well as I do.

And, of course, the engineering idea of a backup system is a very powerful idea. The engineering idea of breakpoints—that’s a very powerful model, too. The notion of a critical mass—that comes out of physics—is a very powerful model.

And all of this cost-benefit analysis—hell, that’s all elementary high school algebra, too. It’s just been dolled up a little bit with fancy lingo.

I suppose the next most reliable models are from biology/ physiology because, after all, all of us are programmed by our genetic makeup to be much the same.

And the reason why is that the perceptual apparatus of man has shortcuts in it. The brain cannot have unlimited circuitry. So someone who knows how to take advantage of those shortcuts and cause the brain to miscalculate in certain ways can cause you to see things that aren’t there.

And so just as a man working with a tool has to know its limitations, a man working with his cognitive apparatus has to know its limitations. And this knowledge, by the way, can be used to control and motivate other people….

The elementary part of psychology—the psychology of misjudgment, as I call it—is a terribly important thing to learn. There are about 20 little principles. And they interact, so it gets slightly complicated. But the guts of it is unbelievably important.

“The mind of man at one and the same time is both the glory and the shame of the universe.”

One approach is rationality—the way you’d work out a bridge problem: by evaluating the real interests, the real probabilities and so forth. And the other is to evaluate the psychological factors that cause subconscious conclusions—many of which are wrong.

Now we come to another somewhat less reliable form of human wisdom—microeconomics. And here, I find it quite useful to think of a free market economy—or partly free market economy—as sort of the equivalent of an ecosystem….

Just as in an ecosystem, people who narrowly specialize can get terribly good at occupying some little niche. Just as animals flourish in niches, similarly, people who specialize in the business world—and get very good because they specialize—frequently find good economics that they wouldn’t get any other way.

because in terms of which businesses succeed and which businesses fail, advantages of scale are ungodly important.

The very nature of things is that if you get a whole lot of volume through your joint, you get better at processing that volume. That’s an enormous advantage. And it has a lot to do with which businesses succeed and fail….

So, in effect, Wrigley , simply by being so well known, has advantages of scale—what you might call an informational advantage.

Another advantage of scale comes from psychology. The psychologists use the term social proof. We are all influenced—subconsciously and to some extent consciously—by what we see others do and approve. Therefore, if everybody’s buying something, we think it’s better. We don’t like to be the one guy who’s out of step.

The social proof phenomenon which comes right out of psychology gives huge advantages to scale—for example, with very wide distribution, which of course is hard to get. One advantage of Coca-Cola is that it’s available almost everywhere in the world.

There’s another kind of advantage to scale. In some businesses, the very nature of things is to sort of cascade toward the overwhelming dominance of one firm.

“To hell with it. We’re either going to be # 1 or #2 in every field we’re in or we’re going to be out. I don’t care how many people I have to fire and what I have to sell. We’re going to be #1 or #2 or out.”

That was a very toughminded thing to do, but I think it was a very correct decision if you’re thinking about maximizing shareholder wealth. And I don’t think it’s a bad thing to do for a civilization either, because I think that General Electric is stronger for having Jack Welch there.

That’s what happened to The Saturday Evening Post and all those things. They’re gone. What we have now isMotocross—which is read by a bunch of nuts who like to participate in tournaments where they turn somersaults on their motorcycles. But they care about it. For them, it’s the principal purpose of life. A magazine called Motocross is a total necessity to those people. And its profit margins would make you salivate.

The great defect of scale, of course, which makes the game interesting—so that the big people don’t always win—is that as you get big, you get the bureaucracy. And with the bureaucracy comes the territoriality—which is again grounded in human nature.

And the incentives are perverse.

They also tend to become somewhat corrupt.

The constant curse of scale is that it leads to big, dumb bureaucracy—which, of course, reaches its highest and worst form in government where the incentives are really awful. That doesn’t mean we don’t need governments—because we do. But it’s a terrible problem to get big bureaucracies to behave.

CBS provides an interesting example of another rule of psychology—namely, Pavlovian association. If people tell you what you really don’t want to hear what’s unpleasant—there’s an almost automatic reaction of antipathy. You have to train yourself out of it. It isn’t foredestined that you have to be this way. But you will tend to be this way if you don’t think about it.

So life is an everlasting battle between those two forces—to get these advantages of scale on one side and a tendency to get a lot like the U.S. Agriculture Department on the other side—where they just sit around and so forth. I don’t know exactly what they do. However, I do know that they do very little useful work.

On the subject of advantages of economies of scale, I find chain stores quite interesting. Just think about it. The concept of a chain store was a fascinating invention. You get this huge purchasing power—which means that you have lower merchandise costs. You get a whole bunch of little laboratories out there in which you can conduct experiments. And you get specialization.

How does a guy in Bentonville, Arkansas with no money blow right by Sears, Roebuck? And he does it in his own lifetime—in fact, during his own late lifetime because he was already pretty old by the time he started out with one little store….

Walton, being as shrewd as he was, basically broke other small town merchants in the early days. With his more efficient system, he might not have been able to tackle some titan head-on at the time. But with his better system, he could destroy those small town merchants. And he went around doing it time after time after time. Then, as he got bigger, he started destroying the big boys.

Well, that was a very, very shrewd strategy.

Here’s a model that we’ve had trouble with. Maybe you’ll be able to figure it out better. Many markets get down to two or three big competitors—or five or six. And in some of those markets, nobody makes any money to speak of. But in others, everybody does very well.

Over the years, we’ve tried to figure out why the competition in some markets gets sort of rational from the investor’s point of view so that the shareholders do well, and in other markets, there’s destructive competition that destroys shareholder wealth.

The great lesson in microeconomics is to discriminate between when technology is going to help you and when it’s going to kill you. And most people do not get this straight in their heads. But a fellow like Buffett does.

That’s such an obvious concept—that there are all kinds of wonderful new inventions that give you nothing as owners except the opportunity to spend a lot more money in a business that’s still going to be lousy. The money still won’t come to you. All of the advantages from great improvements are going to flow through to the customers.

So you keep buying things that will pay for themselves in three years. And after 20 years of doing it, somehow you’ve earned a return of only about 4% per annum.

That’s the textile business.

Then there’s another model from microeconomics which I find very interesting. When technology moves as fast as it does in a civilization like ours, you get a phenomenon which I call competitive destruction. You know, you have the finest buggy whip factory and all of a sudden in comes this little horseless carriage. And before too many years go by, your buggy whip business is dead. You either get into a different business or you’re dead—you’re destroyed. It happens again and again and again.

The cash register was one of the great contributions to civilization. It’s a wonderful story. Patterson was a small retail merchant who didn’t make any money. One day, somebody sold him a crude cash register which he put into his retail operation. And it instantly changed from losing money to earning a profit because it made it so much harder for the employees to steal….

But Patterson, having the kind of mind that he did, didn’t think, “Oh, good for my retail business.” He thought, “I’m going into the cash register business.” And, of course, he created National Cash Register.

And he “surfed”. He got the best distribution system, the biggest collection of patents and the best of everything. He was a fanatic about everything important as the technology developed. I have in my files an early National Cash Register Company report in which Patterson described his methods and objectives. And a well-educated orangutan could see that buying into partnership with Patterson in those early days, given his notions about the cash register business, was a total 100% cinch.

So you have to figure out what your own aptitudes are. If you play games where other people have the aptitudes and you don’t, you’re going to lose. And that’s as close to certain as any prediction that you can make. You have to figure out where you’ve got an edge. And you’ve got to play within your own circle of competence.

And people who could never win a chess tournament or stand in center court in a respectable tennis tournament can rise quite high in life by slowly developing a circle of competence—which results partly from what they were born with and partly from what they slowly develop through work.

So some edges can be acquired. And the game of life to some extent for most of us is trying to be something like a good plumbing contractor in Bemidji. Very few of us are chosen to win the world’s chess tournaments.

The first question is, “What is the nature of the stock market?” And that gets you directly to this efficient market theory that got to be the rage—a total rage—long after I graduated from law school.

The model I like—to sort of simplify the notion of what goes on in a market for common stocks—is the pari-mutuel system at the racetrack. If you stop to think about it, a pari-mutuel system is a market. Everybody goes there and bets and the odds change based on what’s bet. That’s what happens in the stock market.

I used to play poker when I was young with a guy who made a substantial living doing nothing but bet harness races…. Now, harness racing is a relatively inefficient market. You don’t have the depth of intelligence betting on harness races that you do on regular races. What my poker pal would do was to think about harness races as his main profession. And he would bet only occasionally when he saw some mispriced bet available. And by doing that, after paying the full handle to the house—which I presume was around 17%—he made a substantial living.

You have to say that’s rare. However, the market was not perfectly efficient. And if it weren’t for that big 17% handle, lots of people would regularly be beating lots of other people at the horse races. It’s efficient, yes. But it’s not perfectly efficient. And with enough shrewdness and fanaticism, some people will get better results than others.

The stock market is the same way—except that the house handle is so much lower. If you take transaction costs—the spread between the bid and the ask plus the commissions—and if you don’t trade too actively, you’re talking about fairly low transaction costs. So that with enough fanaticism and enough discipline, some of the shrewd people are going to get way better results than average in the nature of things.

How do you get to be one of those who is a winner—in a relative sense—instead of a loser?

And the one thing that all those winning betters in the whole history of people who’ve beaten the pari-mutuel system have is quite simple. They bet very seldom.
 It’s not given to human beings to have such talent that they can just know everything about everything all the time. But it is given to human beings who work hard at it—who look and sift the world for a mispriced be—that they can occasionally find one.

And the wise ones bet heavily when the world offers them that opportunity. They bet big when they have the odds. And the rest of the time, they don’t. It’s just that simple.

That is a very simple concept. And to me it’s obviously right—based on experience not only from the pari-mutuel system, but everywhere else.

How many insights do you need? Well, I’d argue: that you don’t need many in a lifetime. If you look at Berkshire Hathaway and all of its accumulated billions, the top ten insights account for most of it. And that’s with a very brilliant man—Warren’s a lot more able than I am and very disciplined—devoting his lifetime to it. I don’t mean to say that he’s only had ten insights. I’m just saying, that most of the money came from ten insights.

So you can get very remarkable investment results if you think more like a winning pari-mutuel player. Just think of it as a heavy odds against game full of craziness with an occasional mispriced something or other. And you’re probably not going to be smart enough to find thousands in a lifetime. And when you get a few, you really load up. It’s just that simple.

So what makes sense for the investor is different from what makes sense for the manager. And, as usual in human affairs, what determines the behavior are incentives for the decision maker.

And it was always screwed up. They could never get it done on time. They tried everything—moral suasion, threats, you name it. And nothing worked.
 Finally, somebody got the idea to pay all these people not so much an hour, but so much a shift—and when it’s all done, they can all go home. Well, their problems cleared up overnight.

All right, we’ve now recognized that the market is efficient as a pari-mutuel system is efficient with the favorite more likely than the long shot to do well in racing, but not necessarily give any betting advantage to those that bet on the favorite.

In the stock market, some railroad that’s beset by better competitors and tough unions may be available at one-third of its book value. In contrast, IBM in its heyday might be selling at 6 times book value. So it’s just like the pari-mutuel system. Any damn fool could plainly see that IBM had better business prospects than the railroad. But once you put the price into the formula, it wasn’t so clear anymore what was going to work best for a buyer choosing between the stocks. So it’s a lot like a pari-mutuel system. And, therefore, it gets very hard to beat.

What style should the investor use as a picker of common stocks in order to try to beat the market—in other words, to get an above average long-term result?

A standard technique that appeals to a lot of people is called “sector rotation”.

The second basic approach is the one that Ben Graham used—much admired by Warren and me. As one factor, Graham had this concept of value to a private owner—what the whole enterprise would sell for if it were available. And that was calculable in many cases.

But such is the nature of people who have a hammer—to whom, as I mentioned, every problem looks like a nail that the Ben Graham followers responded by changing the calibration on their Geiger counters. In effect, they started defining a bargain in a different way. And they kept changing the definition so that they could keep doing what they’d always done. And it still worked pretty well. So the Ben Graham intellectual system was a very good one.

Of course, the best part of it all was his concept of “Mr. Market”.

To Graham, it was a blessing to be in business with a manic-depressive who gave you this series of options all the time. That was a very significant mental construct. And it’s been very useful to Buffett, for instance, over his whole adult lifetime.

And once we’d gotten over the hurdle of recognizing that a thing could be a bargain based on quantitative measures that would have horrified Graham, we started thinking about better businesses.

And, by the way, the bulk of the billions in Berkshire Hathaway have come from the better businesses. Much of the first $200 or $300 million came from scrambling around with our Geiger counter. But the great bulk of the money has come from the great businesses.

So we didn’t have to be governed by any such construct. And we came to this notion of finding a mispriced bet and loading up when we were very confident that we were right. So we’re way less diversified. And I think our system is miles better.

In investment management today, everybody wants not only to win, but to have a yearly outcome path that never diverges very much from a standard path except on the upside. Well, that is a very artificial, crazy construct. That’s the equivalent in investment management to the custom of binding the feet of Chinese women. It’s the equivalent of what Nietzsche meant when he criticized the man who had a lame leg and was proud of it.

How many of you have 56 brilliant ideas in which you have equal confidence? Raise your hands, please. How many of you have two or three insights that you have some confidence in? I rest my case.

I’d say that Berkshire Hathaway’s system is adapting to the nature of the investment problem as it really is.

Over the long term, it’s hard for a stock to earn a much better return than the business which underlies it earns. If the business earns 6% on capital over 40 years and you hold it for that 40 years, you’re not going to make much different than a 6% return—even if you originally buy it at a huge discount. Conversely, if a business earns 18% on capital over 20 or 30 years, even if you pay an expensive looking price, you’ll end up with a fine result.

So the trick is getting into better businesses. And that involves all of these advantages of scale that you could consider momentum effects.

How do you get into these great companies? One method is what I’d call the method of finding them small get ‘em when they’re little. For example, buy Wal-Mart when Sam Walton first goes public and so forth. And a lot of people try to do just that. And it’s a very beguiling idea. If I were a young man, I might actually go into it.

Finding ‘em big obviously is very hard because of the competition. So far, Berkshire’s managed to do it. But can we continue to do it? What’s the next Coca-Cola investment for us? Well, the answer to that is I don’t know. I think it gets harder for us all the time….

And ideally and we’ve done a lot of this—you get into a great business which also has a great manager because management matters. For example, it’s made a great difference to General Electric that Jack Welch came in instead of the guy who took over Westinghouse—a very great difference. So management matters, too.

However, averaged out, betting on the quality of a business is better than betting on the quality of management. In other words, if you have to choose one, bet on the business momentum, not the brilliance of the manager.

Even with a 10% per annum investment, paying a 35% tax at the end gives you 8.3% after taxes as an annual compounded result after 30 years. In contrast, if you pay the 35% each year instead of at the end, your annual result goes down to 6.5%. So you add nearly 2% of after-tax return per annum if you only achieve an average return by historical standards from common stock investments in companies with tiny dividend payout ratios.

But in terms of business mistakes that I’ve seen over a long lifetime, I would say that trying to minimize taxes too much is one of the great standard causes of really dumb mistakes. I see terrible mistakes from people being overly motivated by tax considerations.

There are huge advantages for an individual to get into a position where you make a few great investments and just sit back and wait: You’re paying less to brokers. You’re listening to less nonsense. And if it works, the governmental tax system gives you an extra 1, 2 or 3 percentage points per annum compounded.

Within the growth stock model, there’s a sub-position: There are actually businesses, that you will find a few times in a lifetime, where any manager could raise the return enormously just by raising prices—and yet they haven’t done it. So they have huge untapped pricing power that they’re not using. That is the ultimate no-brainer.

All they had to do was to cut out all the folly and go back to the perfectly wonderful business that was lying there. And when you think about it, that’s a very simple model. And it’s repeated over and over again.

And, in GEICO’s case, think about all the money we passively made…. It was a wonderful business combined with a bunch of foolishness that could easily be cut out. And people were coming in who were temperamentally and intellectually designed so they were going to cut it out. That is a model you want to look for.

And you may find one or two or three in a long lifetime that are very good. And you may find 20 or 30 that are good enough to be quite useful.
