On Confidence

I get a fair amount of emails both from readers of the blog and listeners to the podcast. Most of the emails come from people who listen to the podcast. The two most common varieties are: 1)Before I listened to your podcast, I thought investing was impossibly complicated; now, I think it may be simple enough for someone like me.2)Before I listened to your podcast, I though investing was simple; now, I think it may be too complicated for someone like me.”

Part of the reason for these two very different reactions is the nature of the podcast. I talk for almost half an hour about things that aren’t regularly discussed at length by the financial media. So, it’s natural for listeners to feel I’m discussing something familiar in an unfamiliar way.

That can cause listeners to question some of their beliefs, especially if those beliefs weren’t all that firmly held to begin with. Most people’s beliefs about investing are very tenuous. There are, of course, people who are very passionate about investing. They don’t view investing as some esoteric subject, but rather as a field intimately connected to the human behavior they observe in their everyday lives.

For everyone else, however, beliefs about investing come in the form of passive knowledge. The tendency is simply to accumulate an inventory of conventional dictums. Investing beliefs are formed much the way a student prepares for a test. If the subject of investing were as simple as a third grade spelling bee, this wouldn’t be a problem.

But, investing is a far more complex subject. That isn’t to say it is necessarily a difficult subject. For some, it is relatively easy. But, it is never simple. An investor can not analyze relationships with the certitude and precision a physicist can. The investor is concerned with human phenomena, which are necessarily complex phenomena.

The complexity of the subject is what makes it appear so difficult. While you can develop a set of guiding principles, it is impossible to devise rules that will lead you to the best course of action in each and every case.

If you try to build an intellectual edifice based on principles such as high returns on equity, strong consumer franchises, low price-to-earnings ratios, low enterprise value-to-EBIT ratios, high free cash flow margins, and rock solid balance sheets – you will fail.

The entire structure will collapse, leaving the architect disillusioned. Why? Because the items listed above are desirable attributes – nothing more and nothing less. They are not true principles. Even as rules of thumb, they are badly flawed. Ultimately, investment decisions are not made about general classes; they are made about special cases.

Every investment decision requires good judgment and sound reasoning. You need to start with the correct principles. But, principles alone are not enough. You aren’t being asked what the law is, you’re being told to apply the law to the case before you.

This is where a lot of people start to feel overwhelmed. Having learned that investing is not simply a matter of running down a checklist, they don’t know where to begin.

The answer is to start with what you know best. Begin with your most strongly held beliefs. Subject them to honest scrutiny. Then, and only then, apply them to the case at hand.

Do you believe the concept of intrinsic value is a valid one? Do you believe it is a useful model? If so, then begin there. What does the concept of intrinsic value really mean? What conclusions follow from this belief?

In the case of intrinsic value, the most difficult conclusion you’ll have to grapple with is the idea that you can pay too much for a great business. For some, this is a relatively simple conflict to resolve. For whatever reason, they prefer cheap merchandise to quality merchandise.

For others, the conflict between intrinsic value and investing in great businesses is painfully difficult to resolve. But, if you are ever going to have confidence in your judgments, you have to be willing to submit your investment beliefs to honest scrutiny. You have to be your own prosecutor. You have to present the evidence against your thesis.

If you aren’t willing to do that, you’ll end up questioning the investment beliefs you do hold every time you underperform the market. Many proven investment techniques have lagged the market over short periods of time. Occasionally, the performance gap has been very wide. Regardless of whether you adopt a primarily qualitative or primarily quantitative approach to investing, this short-term underperformance is unavoidable.

It’s avoidable in the sense that a good investor can get lucky and not suffer a down year for a decade or so. Likewise, it’s possible to outperform an index year after year – if you’re lucky. But, it isn’t possible to adopt a strategy that guarantees such outperformance.

The best you can do is adopt a strategy that offers the right odds. A series of investment operations undertaken in accordance with such a strategy will not guarantee favorable outcomes in every case, but it should provide satisfactory results over the long-term.

There’s more than one way to skin a cat. I don’t want to encourage dogmatism. But, I do want to make sure you do not confuse that which is conventional with that which is reasonable. There is a lot of conventional, moderate sounding advice given to investors that does not hold up to careful scrutiny.

The most obvious example is diversification. Making a series of bets on separate high-probability events is an excellent idea. Diversifying across several different asset classes and hundreds of securities is something entirely different. Even if there are hundreds or thousands of excellent investment opportunities, it does not follow that an investor ought to make every reasonable bet. After all, some will appear to be more reasonable than others. There is no sense in taking on several difficult tasks in the hopes of achieving a result that can be produced by taking on a few very easy tasks.

You don’t have to agree with me on all these issues – most people don’t. But, it is vital that you question the unstated assumptions upon which an investment operation is based. You might come to the same conclusion as those who engage in wide diversification. But, you need to come to that conclusion on your own.

Many investors have not even bothered to consider the underlying premise of diversification. They aren’t really sure why diversification is a desirable strategy. They don’t know how it minimizes risk or at what point the benefit from adding an additional position becomes immaterial. Diversification may be a prudent strategy. But, you can only decide that for yourself after you’ve considered the benefits in terms of risk reduction and the detriments in terms of selectivity reduction.

If I were forced to spend my life betting on horse races, I’m quite certain I would bet on very few races. Whenever I did bet on a race, I’d bet on several different horses.

Why? Because I know more about people than I do about horses. The likelihood that a few horses in a few races get too much favorable attention seems much greater than the likelihood that I could ever make reasonably specific judgments as to which horse is most likely to win a given race. Of course, I would do best if I didn’t bet on any horse races at all.

So, the question is whether stocks are anything like horses. I don’t think they are. When it comes to businesses, I’m a lot more comfortable with the idea of picking the few winners from the many losers – especially when the odds get out of whack. The one tactic that would remain the same is inaction. Acting less and thinking more is sound advice wherever money or commitment is concerned.

A successful investor has to have confidence in his judgments. I don’t know how you can gain that confidence without subjecting your beliefs to honest scrutiny. An unexamined philosophy will never exorcise your deepest doubts – and for as long as these doubts remain, you will be unable to find the confidence you seek.

Good stuff Geoff.

As a new investor I think the problem is the lack of forceful discussion of security analysis as both a scientific and a philosophical discussion, with both being equally important.

For me the important questions which need to be asked with respect to a company must always be: where have we been, where are we now, and where will we be.

History tells us that every beginning must have an end and this applies to companies as well, no matter how strong they have been or currently are.

The last 100-120 years of the market has shown that there are very few companies whose greatness lasted for more than 20-40 years (by this mean I do not inlcude its growth or decline phases but rahter that period where it was dominant, e.g., WMT has grown and is dominant but only hindsight 20 years hence can tell us whether we are witnessing a pause before it grows again or the beginning of its decline).

In fact if you were to exclude those companies whose products are addictive (e.g. BUD UST KO) there are very few companies who have been able to avoid a decline (GE is one that comes to mind, simply because it was and is I believe the only company to still exist form the orginal DJIA that continues to perform well using common metrics which define a good to great company)

For me, as one progresses from the past to the future, understnding that metrics which confirm what has been and is a good company have less utlity to deterime what will be a good company.

Obviosuly this is because I wish to embrace the comfort of knowing as opposed to thinking.

But as one looks to the future investing becomes less a confirmable science and more a theoritcal art. And as a human being I would like to know I am right when I have to pick a road to travel at the crossroads.

But unless I am "Hari Seldon" I cannot know now what choice is the right road, and that is because unlike Mr. Seldon I cannot perdict the future.

But what I can do is think, accept that I can never confirm today that I will be right or wrong about tomorrow until it is too late, and simply follow Benjamin Graham's teachings about MOS so that if I am right I will be right in a big way and if I am wrong I will only be wrong in the lost opportunity of some other investment.

As always after 5 months of study I know enough to know that I dont know nuthin (thats the Munger in me). But for me thinking about what might be and increasing the opportunity that I may be right one day is a more benefical exercise than trying to figure out a way to know I am right.

Thanks for the post it got me thinking and thats about the best thing I can say about any thing I read.


investing becomes less
have begun to realize that metrics (high ROE, EV/EBIT, FCF margins) may tel

Wow! What a great post, Geoff. Some fabulous nuggets in there for any investor.

I like your bit on explaining diversification, but also you r take on inaction - acting less and thinking more ...

Thanks,

The unexamined life is not worth living, but the unlived life is not worth examining ...

For a few years now, I've been striving to get all my beliefs to be internally consistent with not only other beliefs, but with my actions. That's easier said than done, and I'm a long ways away from that end. But what surprises me daily is how much better life is for having attempted that examination; and I'm also surprised by how few people attempt it.

My advice would be twofold: first, learn how to say "I was wrong" without emotion, like a scientist trying to find the right combination of molecules for a project; and second, learn to recongize cognitive dissonance and act on it.

I shall take the contrary track. This is a BAD post because the ideas presented are too messy to grasp. Indeed the complicated presentation correlates to the post's view that investing is complex.

Investing need not be complicated. What's compicated is finding a sufficiently consistent investment method that is sufficiently sound and suits the individual's psychology.

I repeat -- sufficiently consistent, NOT totally consistent; sufficiently sound, NOT totally sound.

However, I do grasp one point the auther is trying to make-- test your theories rigorously for soundness and for building confidence. Perhaps I should add test it with a bit real money to increase realism.

Lastly, for more understanding, probably Karl Popper's books or the "Fooled by Randomness" by Nassim Taleb will be useful

You make a good point about the difference between a method that is sufficiently consistent and a method that is totally consistent.

Especially in investing, the best model is the most useful model not necessarily the most accurate model (and certainly not the most detailed model). I've said before that I think investors need to focus on what's constant, consequential, and calculable. It isn't necessary to consider those things that can be counted but are of little consequence.

I also agree with you about Popper. His ideas are relevant to investors.

Finally, you're right about using real money. First, the theory has to be sound. Then, you have to stick to it. It isn't enough to test the method; you also have to test yourself.

Many investors fail even when they have the right method, because they don't stick to it. That's where confidence comes in. A deeper knowledge of the theory can lead to greater confidence in its execution.
